:crazy: i put my BBK throttle body on the other day,let me go back in time a little. I installed the holly staelth ram 2 weeks back ,got it all soughted and running again.Impressive as i have had one before.Now i thought this time i will put a BBk throttle body on,nothing big just standard 52mm.well started her up and would'nt run and huge sucking noise's ,oops must have air leak.stripped it down found i shuold use the supplied screws not the old ones cos they too long and did'nt seal properly. put it back on ,started up and she runs but still lot of sucking noise. Tracked it down to the air filter box,man do these things suck more than a stock t.b. Really goes now, smooth and never ending revs .
