Ladies and gents, how about one of these for a super-trick PT chassis?

I got a close-up look at an engine-tranny assembly yesterday, and it's super trick. Dry sump, twin superchargers, 6-speed, super lightweight (under 500 lbs for the engine+trans), and super compact.
It's spendy, but in a light car with a bunch of gear, it would be a rocket.

I don't know. :hmm: I'm kinda partial to the V12s myself :yeah: :drive2:

those motors are amazing that would be THE choice for a kit car in my opinion...do they machine their own parts? or are they based of a production engine?

It's basically a Chevrolet IRL engine (not a mass produced 3.8 liter) that is detuned for street applications. The CR and cams are changed, and twin superchargers added. The overall engine is very compact, even with the low-mount accessories and dry sump components.
With a 300+lb front end weight reduction, plus the engine/tranmission center of mass is effectively moved back and possibly lower, it's a great arrangement.

I saw one of these (not street version but real IRL motor) in a stretched roadster at Bonneville a couple of years ago.

Its suspension could use a lot of improvements even for just going in straight, and I'd imagine rear susp (if there's any) has similar deficiencies. The car span around at least a couple of times.
But the car sure went fast when it went straight (240ish IIRC). With a flat-plane crank, the engine sounded like a 1000cc 4cyl motorcycle at idle, and it screamed at high rpm.
