the 88mm will be too small to be efficiant on just about any big block, I'd lean more towards the Procharger. Especially if they'll let you neck down an F2 or F3 to meet the 4" inlet requirement.

If not I'd look at going with the 94mm with the 3.5" restrictor, probably the best overall fit for the turbo option.

Sounds Like

Sounds like our Extreme Street class here. With the exception of strict 29x10.50 tire and they allow wheelie bars. Also only one nitrous kit allowed. Pretty well dominated by nitrous cars, but turbos can be competitive too.

Fastest pass as far as I know is 5.19 @ 135 and some change. Big Block Chevy powered first gen Camaro.

Damn!!! I thought it was a big block!

When I read those rules and saw BOP's race at small block weight, you are the firsy guy I thought of. You could make a killing at that race!

i don't think i could get my car light enough with the no-lexan rule since mine has a mild steel cage. but if someone were to build a fairmont from the ground up then.........

If you build a turbo car right it could compete. Does it say where you have to put the restricter at on the larger turbo sizes?
