Thread: Cam Questions

I've found that the BC STG 3's were alike, in the sense that they buck annoyingly at low RPM's. Funny thing is that after removing the stock manifold and getting rid of the AAC, the issues went away. Occasionally I would get a SLIGHT buck, but I blame that more on the clutch/tranny.

yeah i would say ppl getting the bucking is probably more so due to the aac valve opening and closing causing the bucking, hence why when you got rid of the aac valve the bucking went away, i too had the problem, but my solution which really wasnt a solution was to open the aac valve up a little more and the bucking wasnt as frequent.adding in more fuel down low can also get rid of the bucking too

thanks for the help guys

S4 cams. Ive had them in for a few thousand miles now. At around 4500 RPM it feels like a totally different car. With a lightened drivetrain you will feel it more. Nissanguy has seen and heard me drive away. A lightened drivetrain will balance out the power loss down low. I made 160whp with my S4s at 10* timing.

I have a UR Crank and Alt pully
Power steering removed
Water Pump removed. (replaced with an electrical water pump)
8.5 lbs Fidanza Flywheel with a 6 puck unsprung clutch disc.
The car is super rev happy. The next thing I want to do is bore out the IM and get a bored out TB from Overkill.

^^^No BS, oh and americo my cuz says my car does they same thing( ) when it gets around 4500-5000

Cheers, I'm sure there is more work to be done on the map...I'll get them to take a better look next time it's on the dyno.
