Going through my current 427 that Ive ran both n/a (545rwhp) and with 8 psi from a Vortech T trim (726rwhp). Was roughly 10.75:1 but with the new heads it should be down to 9.6-9.7:1. Ran 93 and a meth kit to get by with the boost and compression. Carb blowthrough setup.

Its not an all out race setup as I drive the car up to an hour for local meets,cruise ins,etc. Still will be a straight drive car. (Currently a TKO,possibly a T56 magnum swap). Ill say my tolerance for whats a "street car" is higher than a lot of people.

I'd like to see 1000-1200 rwhp on 93 and meth. Figured twins and lots of cubes was the easiest way to make this possible. Been looking at the new SXE Borg Warner 69mm turbos. Seem to have a decent size exhaust wheel and are priced pretty nice. What exhaust housings would be better to go with?

427 wil have Avenger 230cc cnc ported heads w/70cc chambers,comp cams 116 lobe high 600's lift solid rolller (thinkig the duration is in the 260's at .050),super victor intake,csu carb,etc

If anyone has other suggestions on turbos Im open to them.

Thanks for the advice,
Billy

 

the 91ar (dual entry)usually spools better than the .88(single entry)

 

Appreciate the info. If you happen to sell these units could you PM me a price on a pair with the 91 exhaust housings shipped to 28112?
