As for more than 25psi on pump it could be possible. I know you could probably go up to 28 but I wasn't sure what his octane turned out to be with that mix.

 

On pump and a track tune the bbk won't do 400 on pump on a MD, and on pump you won't be able to reliably run 25psi on the track. Just won't happen. Personally I would rather run a stock turbo on good gas at the track then Amy aftermarket turbo ever made on pump at the track. 91 just plain sucks for track use.

 

I dont think CBRD makes anything in house but power.
Turbos are made at Blouch in Lebanon and the Fab stuff like IC's, pipes and rads are made at JMFab out by Philly area.

 

hfs-1, full bolt on's, 272 cams and gears, FMIC, and a good tune can put you there.
