What are the specs on the engine?
is the the 1.8 20v that is used in formula palmer?
From my original post "Audi/VAG Formula car powertrain originaly used in FPA and developed further for F2" - so yes..... but it's a development of the F2 powertrain for use in this application. is the the 1.8 20v that is used in formula palmer?
It has slightly more capacity than the original 20V, rods, crank, pistons, head casting, valves, cams etc. etc. are specific to this application. It's dry sumped and runs with significant crank case depression, turbo is a modified GT35R on an inconel equal length manifold with Tial water cooled wastegate. It revs to 9000RPM, runs up to 2.8bar boost and makes over 500bhp at this. 600bhp available if we wish to run more expensive fuel, different cams and a larger turbo.

Just in case anyone thinks these are fragile or in some way not as capable of taking abuse as an original F1 a slight mistake on Saturday afternoon led to this:

No damage beyond a scrape on the floor - we build them strong!
Ok. Which joker put the wings on upside down.

Quality job poppop. Always a pleasure reading your threads.

2.8bar! Wow!It has slightly more capacity than the original 20V, rods, crank, pistons, head casting, valves, cams etc. etc. are specific to this application.

That’s a pretty epic build! I’ve always thought something like a triple or quad rotor rotary engine would be a good unit for something like this, 5-600bhp is more than possible on a bridge ported engine, N/A, mega responsive and a truly awesome noise
5000kms between rebuild though? 
This highly tunes quad rotor managed a decent distance without needing a rebuild. Just some fuel and an oil top up....

The driver ran out of talent having got too excited on the straight, and forgot PPB's advice to "warm the Carbon Brakes... BEFORE you need to use them in anger" bloody idiot but no damage done.Photo credit to Steve Mangelschots via Instagram.

Awesome write up PPB looking forward to a fun summer!

There’s a fair few triple rotor RX7’s around the world used on the road doing more than 3000 miles between rebuilds... Rotary engines aren’t as unreliable as people think.

Ive got a spanking new built Triple Rotor motor if you can use it? I had it built for this project initially but PPB's plan was better. Im now looking for a Mk2 Escort Shell to install it in over the winter. This highly tunes quad rotor managed a decent distance without needing a rebuild. Just some fuel and an oil top up....

Can we please build it with the Sadev in the back carrying the rear suspension and an engine speed prop like the Aston GT2/GTE?

The difficulty is running them as a stressed member. The castings are thin and rely on long bolts to clamp them together, you simply can't hang the whole back of the car off them. For an F1 or similar this becomes a major issue, especially on a modern chassis as they are so narrow and tightly packaged there isn't room to run big engine frames and rear bulkhead plates to destress the engine without massively compromising the aero surfaces and bodywork. If you look at the installation in the 787B here:
You can see just how much structure is around the engine to make sure none of the loads the gearbox sees from the rear suspension are transmitted into the engine itself. With the Audi Formula powertrain we are using you can see how much less structure there is, the block runs stressed and there are just two small side frames which pickup the top of the bell housing which are there mainly due to the bell housing width vs the distance between the block side fasteners.
It's not always about how physically compact something is, it really does come down to how much load you can put through it with these and with a lateral G capability of over 4.5G there is a lot of energy going through noisey bit in the middle of this Sauber
Ahh that is a problem. By the time you’ve managed to build a structure to cover the supporting side of things I’d imagine that removes any real weight and potential packaging advantages. Balls.
I’m off to watch a video of Mad Mikes triple rotor RX8 drift car to cheer myself up with noise

How much does a landing in an F1 car hurt on a scale of 1- Oh Christ my arse is ruined! (I am that driver
