Invent a device that goes into the drivetrain that if more than 300HP is delivered for more than 0.1 seconds the car is made "neutral" for 5 seconds.

Engine rules? Totally open. Since you can only use 300HP, how you make it becomes unimportant.

Unlimited aero. Again, downforce vs. drag, 300HP becomes the limiting factor in itself.

Car style is unrestricted. But you must maintain one configuration throughout the season.

Tracks: 25% ovals, 25% roavals, 25% road courses, 25% street courses. Have fun making an all-around car.

So like world challenge but with open chassis.

Strain gages here we come, don't have the intake restrictor. Would have to program the revs, gear indicator, and program the gear ratios into the limiter, but that would be an intresting concept. 300HP and safety only rules (like Pikes Peak unlimited).

Then the main game would become torque. Instead of shrieking, rev-happy race engines we'd start seeing burbling, lazy strokers. I imagine it's technically possible to create an engine with 600ft-lbs and only 299hp if the revs are kept low enough.

Funny thing: I can think of how I'd design such a device. It probably wouldn't be perfectly precise, but basically an intermediate clutch stage with a ring of metal drive ramps around a faced metal rim. Wedges with friction material set in the gaps would be spring retained, and be forced away from the metal rim by a combination of centrifugal effect and relative torque between their surface (in contact with the rim) and the metal ramps. Abusing it too much would cut the weight of the wedges by friction material lost (and thus disengagement due to RPM), but would also cut required torque to slip, so would self-balance to an extent.

20 or 30 of these on a race track and it would sound like a hippo olympics.

Here is the problem:

A device like this, used for racing, would have to be dead on accurate (and repeatable). it would also have to be able to control the clutch, and therefore the RPMs, otherwise, driver at WOT + sudden, unexpected neutral = blown engine.

In order to build such a device, it would have to be heavy and large, never mind the extra electronic components. This would make it counter intuitive to racing.

What happens when the 'device' lifts mid corner and you spin?

You would just see people screwing with gearing and have 27 speed transmissions or some stupid crap. HP is just (TQ x RPM) / 5252, so you can still get there with crazy ratios. They would just have to do the RPM increase after the device and massively reduce the RPM of the engine... like a diesel or something.

That sounds like it'd be fun to watch and read about, haha.

perhaps dyno test everyone on the same dyno in the same conditions? Dyno is not to exceed 305hp. With several pre-test sessions allowed to get as close as possible to that. People would be all about tuning that car for the HP to hit 300 as low in the rev range as humanly possible. At the same time they'd build to get the highest RPM's possible and having the car be as rev happy as humanly possible. This could be fun!

After firing it off from my phone I realized that it would probably just be some kind of CVT style transmission... so it might actually be even more boring than current racing.

Haha, "CVT racing" could be a great way to get into racing, or it could be a death sentence for any kind of career beyond the CVT style cars, haha.

I think manufacturers have shown they can create fairly flat torque curves, as evidenced particularly by Ford's Ecoboost engine. Perhaps it'd be easier to limit torque, rather than horsepower?

That would be a better solution. Limit the raw torque with a device that lets go at a specific force level... it would be like a clutch that slipped on purpose. That way if they put too much down force and tried to up the power, they couldn't go any faster because the drive train would just slip or disengage.

Lol, I envision VTEC engines, horsepower with no torque.

Then your engine builders got a little too happy.

No, I mean, you're mid corner, powering out, if you hit the limiter and car goes into neutral, you'd be likely to spin.

If you were following the rules, it never should have hit the limiter. You can make 299 all day long, but hit 301 and you get effectively penalized.

Penalized by possibly crashing the entire field?....lol...Sounds like figure 8 racing...

Okay, fine 50cc cars at Talledega. That way nobody can crash.

I didn't say I didn't like the idea...

I like figure 8 racing...
