hey guys...Just Dynoed my car, got these results... 367rwhp @12 psi at 7,300rpm... Problem im having is that the car keeps breaking up from 7-8k. Either a ignition problem, maybe bad ground? Please help me out.

well i bought this car with the current setup from brian ( 1fast7)... he was making 405rwhp @15psi at 7,800rpm....Why im trying to go to 7,800 myself.... He had decent sized street port, P port... I ended up popping the motor a little after i bought it from him... When we bult this motor, we went a good 10-15% bigger on all ports from the current motor....

You gotta stabilize that boost. I make more torque at 10psi with stock ports with a flat torque curve.
Do you see how your torque curve just keeps rising?
I would throw in a pair of stock wires and fresh plug and retest after you get that boost straigthen out.

the tq keep srisign cause boost keeps rising also, the boost contorller is turned off. this is the LEAST boost hea can get, the wastegate is too small so it keeps creeping slowly. we will worry about the flat power band after the breakup is fixed

NGK 9's all around
RB OPR
RB harden stationary gears
Theres no real reason why i want to go to 8k i guess. But the previous motor made 405rwhp @7,800rpm. So why not go to 8k? On the my dyno the HP dosent fall off, so why not go another 1k to make more hp
My main goal is 450rwhp @15psi. If brians dyno was right with the 405rwhp @15psi , then i m hoping i shouldnt have much of a problem getting 450 with all ports being 15% bigger. Of course with good tunning
