Chasing that time slip is addicting, isn't it??
I can tell you from experience that a electric water pump (or drive motor for the OE pump) and an aluminum underdriven crank pulley are a solid tenth at your power level.
Speaking of water pumps: You DO have an aluminum pump and housing, right?
I'd also add light bumper brackets with the bumpers. If they're not available for your car in fiberglass or aluminum, you can "swiss cheese" the OE brackets **Note that if you're having traction issues now, I'd leave the OE bumper on the rear.
I always ask guys too when they're wanting to throw parts at it, are you 110% tuned? Spent a day testing jets, squirters, PV's, timing, startng line and shift RPM points? Tire air pressure...Front AND rear?? At least tuned it on a chassis dyno???
What's the MPH now?
