Now that we have addressed the most powerful car you've ever driven, whats the fastest car you have even been in, but did not pilot?

"Working" or more, spending time at a shop that specializes largely in drag cars has its perks, one is that a few years ago a friend of the shop gave me a ride in his 10 second "street" first gen Rx7. About 600hp and 2500lbs makes this car pretty stout. Its been off the road since not long after this picture was taken (2012), and its about to be back with 800-900hp looking for 8 second time slips haha

We went behind the shop, did a small burnout, sat there, the RPMS raised he hit the nitrous and got off the brake and launched, it was the craziest experience of my young life (i was like 13, in 2010). then we did it again.. when we came back i was speechless, and gave up video games after i got home because i couldn't feel that rush again from them.. ive been in a lot of fast cars, but this car is the holy grail so far..

That, or a supra me and my uncle were out tuning on the highway (shut up, i dont want to hear it, i know its not safe lol).. 850hp made it totally worth cramming in the back seat of a 4th gen supra..

When I was younger, I'm guessing pre teen, the father of a family friend unit was staying with my family. They had been living out of state for some time and were moving back, and he was staying with us for a while to work and get housing sorted for the move. While staying with us he was borrowing someone's f body camaro, I'm guessing it was a 2003? I don't remember. It was white.

Anyways he invited me to come along with him to see the house that they were buying while he was taking care of some paperwork or similar at the main office of the community. The house was in this development out in Memorial City, the outskirts of Houston. It was probably 3 or 4 miles down this empty new road.

We hit this road and he said something to the extent of "want to see what this thing can do?" and floored it. I have no idea how fast we went, probably around 120 or so but it was awesome. That was the fastest Id ever gone in a car, and it's still the fastest I've gone as a passenger

TL;DR: 120ish in a 2003 Camaro

Well it wasn't fast as in top speed achieved, but I got a ride on an autocross course in a complete beast of a Miata. It was stripped for weight, supercharged, had front and rear wings, and ran on 12-inch slicks. G-forces in all directions were insane.

Haven't gotten a ride in it yet, but a close friend's dad just ordered a 2014 GT3, apparently only one of 33 coming to the states this year (I find this hard to believe. however), and he said I'd be the first non-family member to take for a spin. His kids couldn't give two shits about cars, so I'm feeling like I'm turning into the son he never had because I end up getting roped into talking cars for roughly two hours every time I go over there.

But yeah, anyways, 991 GT3!

Maserati Gran Turismo.

I worked in country club management for five years and we had a Gran Turismo at the club as a hole-in-one car for the biggest member-guest event we held each year. We couldn't leave the car outside overnight, so as I was leaving the first day of the event, walking across the lobby, our general manager dropped the keys to me over the rail and told me to take care of it since I was the only one who cared about cars. I won't say how fast I drove it, but it was triple digits and was returned to Maserati of Atlanta with nearly 100 extra miles on the clock. It was fast and fun, but I wouldn't ever want one, regardless of how much money I had.

I have two stories to regale you guys with...

The first occurred when I was younger, about 15, and the vehicle was an 86 IROC Z that had been stripped, built rearend, 454, some sort of transmission swap, and lots of other stuff(I wasn't really into cars at the time so I have no idea what else was all done to it). Anyways, it was New Years Eve and he had just got the car back together after months and months of it sitting in his parents driveway and he asked me if I wanted to go for a ride in it. We went around the block a few times to make sure nothing was going to fall off, then(in our young and dumb mindset) we decide to take off for the some more open road in an unregistered, very questionably street legal, and blacked out car. Anyways... none of the gauges were in the car so I have no idea how fast we actually went, but I do know that we were keeping up with other people on the road when we saw blue lights. Shortly after there were no more blue lights on the horizon and my butthole was puckered for a good 2 hours. It was a damn impressive car, he kept having issues with it and sold it a few months after though.

My second story is one I can give more details on seeing as it was more recent and something that truly catches my interest. I'm a huge rotary fan in all aspects of the title and there aren't too many people who mess with them in this area so it's rare to meet someone who knows what they're talking about. At a car meet one night there was a black FD that looked beat to hell and I figured it was another LS swapped one like all the others in the area(except the one RHD with a 2J in it? 0.o) but on further inspection I found it to be a 13B under the hood, well mostly at least. This thing had zero moneys or fucks given in the appearance but god damn it was done right where it counts. He was running a set of older second gen housings and irons, with modified and lightened Renesis rotors, which left it at 8.9:1 compression with a better combustion chamber shape, he had custom stationary gears made, the only thing stock in the whole block was the e-shaft. Enough rambling about the car though, a few meets later he took me for a ride in it and the 305's on the back did nothing to keep it going straight, most beautiful sounding car I've ever heard too, nothing but turbo/induction noise, kinda like standing next to a jet. He ran just under 40lb of boost and even though motors didn't last long, they were damn impressive. That first ride wasn't the fastest I've ever been in a car, but handily cemented that car as the fastest I've been in. When you have to roll on the throttle in 4th to keep from spinning at 120+, you have enough power.

I sat on one of Rob Muzzy's hand built super bikes once. I drove a modified stock Chevy II one a test drive once, I think it was a ten-second car.

The fastest conveyance I have ever sat in was probably an F-11 Tiger, a mach capable fighter used by the Navy. Other than that airliners or military transport planes. I think a 747 is marginally faster than a C-141, but probably only by a few mph.

Boringly, I'm pretty sure it's one of the German luxury cars with the limiter set to 186mph that I've been in. Haven't been fast-fast in any of them, though, mostly just given a lift in town by someone's dad or whatever.

There are all kinds of much more interesting cars I've been in that get close, but not quite there. A Maserati Bora tops out at about 170ish, for example. An Aston Martin Lagonda 'only' does 150, but it's probably the performance car I've been closest to top speed in, having been a passenger at over 130mph once - empty motorway, early morning, still too fast for any public road but it was only a short burst in the middle of cruising at 100mph.

I just thought of one I forgot about when we were doing fastest cars you've driven yourself. Not sure it counts, but back when they were raising money for the first Thrust SSC record attempt they had an immersive virtual-reality simulator they took around the country - the same one that Andy Green used for training, so ultra-realistic. I had a go on that, and 'drove' well over 500mph.

I've ridden in some fast cars but the one I always like to refer back to is the e38 bmw 740li I test drove. I never go chasing high speeds on public roads and this was no different. Merging on the highway I accelerated until my butt dyno determined it was an appropriate cruising speed and glanced down at the speedo and saw I was going over 100. I had no idea, thought I was doing 60.

33 sounds a bit low I would guess around 80 or so will be in around the first year. Porsche's production numbers bounce around a bit from nearly to 2000 to only 600. Do you know if it is an RS? If it is then 33 sounds a lot more on the money, either way that is going to be a blast once it shows up in the driveway.

Top speed wise, the fastest car I was in was a De-limited E39 535i, which had some mods. I've been in the low 150's, but the thing can go up to the low 160's.
Fastest-Feeling wise, was a 1.9 TDi Audi A3. This car has about 115-120 horsepower, but easily double the torque. It was ah-mah-zing on the twisty south European road I drove (and was driven in) on

They started life at renesis rotors, but had been remachined for 3mm apex seals, had the second oil scraper groove filled since there were no sideports on his engine, and he said the combustion indents were lengthened slightly, and the entire rotor face taken down a bit to reduce the compression ratio but have lighter/stronger rotors. He went through a set of apexes about every 3 months, but running carbon ones kept him from having to do anything besides pop new ones in and give everything a quick cleaning.

I should mention it was also a full p-port motor.

Well we do just about everything, we have an amazing fab guy who does all our piping, we tune and have a tuner whos experienced up to about 1000hp, we at the shop build motors, install anything, do maintenance, put 20bs in cars, put REWs into Rx8s, and rotaries into starlets.

We just finished a sweet half bridge REW Rx8, We're building a 20b rx8 the right way (by cutting the firewall) have a 20b fd getting wired, building a turbo 2 powered first gen, finishing up work on a Rx8 turbo kit we intend on selling, and finishing up maintenance work on a maxton rollerskate which we installed a fuel injected 74 13b into some time ago.

My uncle has been in the business for over 20 years now and is really passionate about the cars, he owns a Rx3, a street Fd, a full tube frame Fd, and a turbo Rx8 (the prototype for the kit)

That sounds amazing. I'm going to school for CE/EE with a minor in mathematics and computer science and I've been getting more and more interested in control systems as well as embedded systems as far as engine management goes. I always take the chance to see what all different shops do in that department(tuning/custom engine management/engine harnesses) since that's an area I'm thinking I might enjoy once I'm out of school, as well as keeping an ear to the ground for internships.

That sounds like a wicked shop though, I'll definitely check it out on Facebook, I have a soft spot for the vintage rotaries for sure.

Yea, tuning is really cool, and really doesnt seem too hard if u understand what youre doing. our guy is a mechanical engineer for the navy and works on boat turbines, he owns a drag first gen and picked up tuning over the last few years for us. there are some pretty amazing guys out there though. one guy apparently does this thing where he puts your car on the dyno and within 3 passes it will be fully tuned. hes the guy to get around here, his name is Wilber, and hes pretty legendary within this branch of the rotary world

Tuning is cool, and there definitely is a big gap between the kids who street tune subbies locally and the guys who actually understand what's going on in the engine and the math behind it that can crank out real precision stuff. My interest is way more piqued by the software behind it all and how to make it more efficient, ECU design hasn't taken as many leaps as it could have with the hardware available these days. If you're allowed to talk about it, what types of engine management do you guys usually use? Standalone stuff, piggy back?


Kinja'd!!! TyFc3s-A car hating millennial > roflcopter
01/05/2014 at 00:20

Kinja'd!!!0

well we only really deal in full stand alones, the closest to a piggie back we get is the apexi power fc which uses the stock harness with a new computer. other than that we use mainly microtechs and haltechs

Both computers could be improved upon, but for us they rock. the microtech is the cheapest stand alone imaginable, u can get a new one for like $1000, the draw back is they kinda suck, not great at full management which is required for a street car, but for drag cars that are at 100% at all times, they rock. The worlds fastest drag rotarys all have that mediocre little computer, and they make 1800hp and run 6.20s

The price also makes them very attractive, like i run a microtech in my car (or i will when its done) because im a broke kid who wants the most powerful N/A 6 port in the world. (~210hp)

The haltech on the other hand is far more sophisticated, but more expensive, and by no means the end all be all of computers. its better around town, and can do the same thing power wise at the microtech, but to most of these kids that doesnt justify the jump in price

Haltech's interesting addition to the battle though is the New (in like 2009) sprint RE, which is a very small computer that was cut down to have only what a rotary need to run. great computers and all for $900! my uncle runs this in his turbo Rx8, but as far as my memory is concerned i only remember us doing one other car with the computer, as turbo 2 powered first gen years ago.

The reason? the world has been taken over by the microtech and its all monkey see monkey do. In all honesty, if everyone was looking for the very best for their $200,000 race cars, we would all run Motechs, but we dont lol

Other options include the electromotive, which we have a good deal of experience with, my uncles street Rx7 runs one, our most famous car a 20b Fd now owned by Rob dahm on youtube, runs one, and all the rest of our 20b cars, because thats the cheapest way to buy a computer capable of running a 3 rotor. It helps that they are located in like virginia too.

Then theres the ProEFI, which to be honest i dont know all that much about, as no rotarys really run the system yet, but theres a shop called undercover racing around these parts that builds supras and Gran nationals (weird combo, i know) and they specialize in it. i think it tunes itself and can instantly switch from map to map depending on the fuel in it, which is great, because most of those cars are tuned for E85 and pump gas, and theres only one place in the area to get E85. But ill let you look into that one yourself, which i hope you will, because its clearly the most advanced system out there right now

But in reality, if the attention that was given to the andriod os was given to aftermarket ECUs, my 200hp goal would be 300hp, our record would be in the low 5s, and we'd all be dead lol, i hope maybe you can help improve them

Thanks for the rundown on what you guys typically use, a lot more information than most people are willing to give.

I suppose when you get into running a rotary things definitely get more complicated and like you said, there aren't a lot of options specifically made for them. In your opinion(since you seem to know a decent bit about it) what is the weakest link in the current offerings? You say that further development to the ECU systems could make big power gains, but I just don't see that since it usually comes down to the mechanical limits of the motor. (think about things that kill an engine, especially a rotary, such as ping and the like, and there isn't much more you can do besides put the 'right' amount of fuel into the chamber and let the mechanics take over. I mean playing with spark advance is definitely a key component, but as long as you can calculate that once per cycle then you've already hit the useful limit on that as well.)


Kinja'd!!! TyFc3s-A car hating millennial > roflcopter
01/05/2014 at 02:05

Kinja'd!!!0

honestly, this is where my knowledge runs out and my questions start as well on both the mechanics and the electronics. Im much more mechanically inclined myself, and have spent years trying to figure out ways in which to improve the motor, with no real "break throughs" yet, but its why i wish to go to college for engineering, to figure it out. as for the electronics, all i can think of is a computer which tunes itself for every variable, one that will take in the temperature, density, humidity, and even atmospheric pressure if it matters to make the car run at its peak every time.

That being said, i do believe there is still a ways to go in each, but at that i do believe that this is the pinnacle of what internal combustion can be. If perfected, a fuel injected (obviously) rotary should be the single most powerful package per size available. It might even be, when you consider we have 13bs making over 1300hp. i dont know any other motor that can make over 1000 hp per liter.

And we are constantly advancing. i remember the first 13b that i know of to make that power ran a 6.90 in 2010. Its a starlet called la otra. it was the world's record car for that motor, but blew up at the top of the track. Nowadays we have plenty of motors doing that in heavier cars round after round, the fastest now is a low 6.80s Rx8. There's plenty of room to move in both fields, in my opinion, but the mechanical field is the only one actually moving right now as both the current rx8, La otra, and the fastest 20b car, all probably ran a Microtech Lt16 (i know they all ran microtechs, just not sure of model)

All that being said brings up another point, which might prove you right, they all ran that same mediocre computer, year after year, car after car, everything is that same computer, but you have winners and losers. would a motech on the same car actually make it that much more powerful. perhaps its all mechanical at this point.

I feel like ive rambled on a bit, but theres a point in there somewhere hahaha

Well if you care to read, here is a good rundown on what you're talking about as well as what I think would be the next step in engine management....

The holy grail you speak of with a car that can tune itself is essentially being done to some extent in just about every car out there today, it's called closed-loop. Most cars use a feedback system to control AFRs and the like at low load/idle/below a certain RPM operation and it is essentially doing what you're talking about, but on a more simple level. It takes the 'output', in the form of a reading from an O2 sensor, and compares that to a target AFR that has been established, usually high 14's low 15's for idle and cruise and adjusts the amount of fuel delivered to compensate. What you're describing is a bit more complex and to apply it to WOT and high load situations the use of lookup tables are typically used, and 'tuning' in the sense most people think is tweaking these tables, then looking at your result, then tweaking them again to get the desired 'outputs' from the car(be it AFR, power, temps, whatever). Originally(such as in the '93 Mustang we race) the tables were super simple and you had very few variables getting looked at, such as RPM, ECT, Baro, and IAT, outside of the actual amount of air moving into the engine in the form of either a MAF or MAP sensor. These other sensors were more of switches than truly instrumentation and they only tell the ECU which table it should be looking at, then the fuel is calculated as a function of RPM and MAF readings. In more modern cars the other sensors have their own tables that act as a multiplier to the main table that is still based off of RPM and air metering, but it's more accurate and easier to mess with the multipliers than with a bunch of different tables like our Mustang uses.

The difference between a good tuner and someone who can just make it work is knowing the math and physics behind those multipliers and the equations you can use to model the changes in air flow/density/volatility that result so that you can get them right in a very short amount of actual dyno time. Your idea of a fully closed-loop system is one I've dabbled with for a little while now, and once I have a few other projects squared away it will probably get fooled around with, at least as a proof of concept. The main hurdles with something like that isn't the power of the ECU itself, I can already run thousands of lines of code in between combustion events even at a 12k redline, it's actually the speed of the feedback system. If you're monitoring AFR's through a wideband O2 sensor located just past the collector(which is the only accurate way to look at the condition of the motor as a whole) then you have lag time between a combustion event happening and the exhaust from that getting to the collector, which doesn't seem like much, and at lower engine speeds and loads the accuracy isn't needed and it's a viable option, but at WOT with a car pushing the limits of what it can handle, having 3-4 engine cycles before correcting for a lean condition, especially in a boosted rotary as I'm sure you're aware, can spell death for that engine with a quickness.

I'll leave it at that hell of a run-on sentence. There's so much to learn about engine management and the methods used vary widely between something truly streetable and a dedicated racecar.

I don't do the passenger thing. I did get to drive an 05 gto putting down nearly 700whp. 6.0, heads, cam, intake, supercharged with supporting stuff. The clutch was horribly touchy, I have been driving manual 15 years and could barely pull of a smooth shift. It was damn fast when it hooked up, but those "little" 275 wide DR's had a hard time doing it.

Nope, not an RS. Apparently the 991 GT3 is not selling as quickly as Porsche would've hoped. I would've figured the usual 10% figure, leaving 80, but he claims 33 are coming to the states. Anyways, it's going to be a blast! There's speculation that an official RS 991 GT3 might never happen because there's a rumor that the GT3 R Hybrid racecar's tech is going to be the next step up in the GT3 rungs.

Back in 1975 (I was 15) I used to hang around a garage in York PA ( I still live here) the owners son had a 9.90 Gas car which he ran at York US 30 before it closed.

He would let me be a passenger during test and tune nights......Holy Mother of God-the initial hit off the line in a car that does the 1/4 in less then 10 seconds is incredible.

It's like being rear-ended by a locomotive doing 110 mph. Something I will never forget as long as I live.
