I have a 2wd cossie with 3" Mongoose, KN, Montune Chip, Turbonetics T34 ar.48, RS500-cooler, grey injectors, low compression pistons, and ported top (???). Had it on a rolling road and the results were 350bhp@6100 rpm., and 417nm@4400rpm. 1,6 bar.
Is it worth buying BD10's?
Because of the small exhaust-housing i can't have more than 6000rpm. (Don't know what you call it in English. Back-boost???

Preassure/boost in the exhaust-housing). Will new camshafts help with this problem? Will i loose power on low rpm?
