I wonder if this twin turbo V6 has anything in common with the Chevrolet Indy Twin Turbo V6 by GM and Ilmor Engineering.This is awesome too have two GM racecars [sorry Nascar...NOT] to root for. And being built by Pratt&Miller you know it's hot......
I believe it does if you check out the Road & Track article in the other thread.I wonder if this twin turbo V6 has anything in common with the Chevrolet Indy Twin Turbo V6 by GM and Ilmor Engineering.
The answer is no, per R&T. This engine is based on the LF3 and is called the LF4.R. Just modified for race use. So, I think we've found the upper limit of the LF3/4 family @ 600hp.I believe it does if you check out the Road & Track article in the other thread.
Also, for those whining about the V badge being up top, this is why:

Sensors are on the bottom of the trunklid.
Transitioning from the one-of-a-kind rumble produced by the V8 CTS-V.R's to the new 3.6-liter twin-turbo V6 follows GM Racing's recent emphasis on promoting its forced-induction technology. Through its relationship with racing-engine builder Ilmor, GM uses a 2.2-liter TT-V6 Chevy powerplant in the Verizon IndyCar Series, and with the new ATS-V.R motor, Vurpillat says the decision was made to keep the project in-house and in the hands of GM Racing's powertrain experts.
"What we really like is the heart of the race car being the 3.6-liter twin turbo. There’s a production variant of that, and I love that linkage between them," he adds, referencing the 600-hp production-based LF4.R engine. "I think that gives us a great marketing story to talk to our owners, to talk to dealers, to talk to prospective buyers. The whole idea of racing for us is growing the Cadillac brand and its performance credentials. If you can tie the race car to the road car, you just get more credibility."
It would need to be paired with some type of hybrid solution. LMP1 engines are pushing 900 - 1000 hp.Wondering if this engine could be used in prototype class-LMP1 maybe?
