625hp@5800rpm in a gear reduced 434 cubic inch Small-Block Chevy. 372 mph. There is awesome video at the end of this. It was designed and built to go racing in the Unlimited class with P-51's and F8F Bearcats, and Super Corsairs but rule changes (It did not meet the 4,500 pound minimum weight) kept it out of that class. The Sport class would have worked but rules there also kept it out (had to have 5 kits produced and sold for homologation) and once they made the super sport class, it had a home.
The super sport class did not require kits to be sold so it had a place for lightweight one-off designs to race as long as they had 1,000 cubic inches or less. The power at that speed had to be reduced for the prop so they went to a reduction unit.
Able to fit to small and big block chevy power as well as Ford windsor and Jag v-12, it has options for your ideas as long as they aren't much more than 900 foot-pounds of torque into the device.
In the end they arrived at a solution that fixed the teething problems. Weak engine with cylinder failure in 2011, and an over-stressed firewall installation let to engineering work and engine development to the present package. Oil starvation above 5,100 rpm in the reduction unit was solved with additional scavenge pumping and further cooling issues were fixed.
After all of that they set a few records and Will be at Reno this September. I highly recommend going. As an airline pilot I really can't take regular airshows. Oshkosh could press my buttons but the only airshow that really does it for me now, is the Reno Air Races in mid-September. You must go or youl'l miss out on wonderful ingenuity like this.

First off ... NEAT!
Second, why in creation would anyone want to trust their lives to a Jaguar V12-powered single-engined aircraft?! O_o

Would have to ask Hasselgren Engineering, their builder. They do seriously high end stuff too so I would believe they do know what they're building for them. I'm sure making it 434 cubic inches with highly loaded internals might have been an issue. Highly loaded meaning up to 6+ G's in turns for 30 seconds at a time or more in a race. Also there could have been space concerns in one way or another.

Who knows. Could be for boats or...i dunno...people in homebuilts have odd ideas and keep trying stuff that others keep having problems with. " My installation of the boat anchored heavy ford 3 liter essex v-6 will outperform anything else" they believe.

I'm just thinking the single most important thing you want in an aircraft engine is reliability ... which a Jag V12 has exactly none of.

Aircraft engines tend to be more reliable because they're typically run at a constant RPM well below the redline. That might be their thinking, but racing an aircraft puts many of the same stresses on an engine as racing a car does and I definitely would not want to put my life in the hands of a Jag V12 at 200 ft AGL and 500+ mph.

Oh yeah, Im sure they know what theyre doing. Customer request maybe? I figured with an LS being physically smaller,lighter, and easy power out of. Why not right.

I think 80+% of the jaag v12 problems can be fixed by replacing the ignition to a better third party digital EFI and ignition system. Such as Electromotive and using competition wiring harnesses and the like. I'm not sure about its mechanical otherness, like is it always blowing head gaskets or spinning bearings? but any of the accessories it has can be replaced with better ones third party.
Really, if someone is going through the expense of using a jag v12, they can easily afford a Falconeer V-12 instead. Makes better sense.

True, but they do need torque, and that engine they built has the torque peak at around 5,100. that't the thing about spinning big props, it does take a bunch of torque. Now, I'd like to see someone install an inverted cummins turbo diesel in something like this and coal roll the skies.

Crikey, that's cool!
Haven't been to Reno for the air races in years. Need to get back.

Yep. Theres' a Subway outside the main gate in a plaza nearby that's open crazy early makin' sandwiches. Grab one for lunch because you won't be able to get up out of your seat from 8-5.

Little late to the party, but do you know what records they were going for and if they got it?
