Hey guys, so i helped a buddy at work put a bbk h pipe in his 94 gt. He has 2 chamber flows and this sunday im going to install a set of underdrive pulleys and bbk 1 5/8 shortys. Oh he also has a bbk cold air. What kind of HP numbers could he see when im all done with everything above installed?
I know in 94 215hp was factory. Thanks! MM
