Why do you say that ?
He's an old school V8 guy. They don't a whole lot of fast turbos. The quickest turbo there lately is 10.7 gutted civic. They had a 9.9 sec AWD DSM shop build many years ago.
He was very surprised the car had twin engine he had just learned that. Plus he didn't expect the 6.3 time on the track. He told me himself the track wasn't sticky today.
besides who cares... The car has a 4t80E and it runs awesome. The trans shifts hard 1st-2nd and shift hard in 3rd gear. Holds power like nothing.
I'm sure it will take the higher boost. I got lucky on my trans.
I am running the tight converter so it's slow spooling. I might need the Aurora 4.0 converter because right now I have to spool the rear engine before the front.
