More so for the automatics

Another recommendation once you start getting up there in power, is having the axle tubes welded on the 8.8 to avoid the possibility of spinning a tube, especially so if running drag slicks.

How bad is it to shift hard from 1st to 2nd and so on? I shift pretty damn quick and before the blower, the car would spin 90% of 2nd, if i get radials and it hooked, what could break?

Slicks. I drop the clutch off of a 2-step at 5,000+ RPMs. Rear end is still bone stock and in excellent shape after over 250 passes at the drag strip. I must admit, however, I seem to have a factory freak when it comes to not breaking anything.

What exactly does altering the timing change in the motor? I understand the effect it has on power but what is being changed in the motor?

And with a blower, HP as measured at the rear wheels is just what's left for fun, it doesn't include the power the motor needs to provide at the crank pulley to pull that blower or drivetrain frictional / windage loses.

Changing timing just changes the point at which the spark plugs fire in the cylinders each time the crank makes a rotation.

The tune is EVERYthing. Get yourself a wideband gauge if you dont already have one. That will put your mind at ease when your WOT and you can see your getting enough fuel. I have 300 or so passes at the track with my car. The only thing to fail was the rear end clutches. I was running slicks until this year, just switched to DRs. These cars are built to be tough but some motors do give up at the 450 point.......but most do not. Enjoy your car dude but remember the tune is everything.

It really depends on the motor's components. Some have blown well under 500, others over 500 are still fine.

The one thing you mentioned that raises a B I G red flag was your fuel delivery issue. As mentioned, you MUST have adequate fuel, with some room to spare, too. If your pump is "running out", it's probably just a stock-ish pump with no circuit upgrades (boost-a-pump) and not a twin-pump setup. YOUR TUNER SHOULD NOT ATTEMPT TO TUNE WITH FUEL RUNNING DRY!!! You WILL eventually pop your motor.

Keep in mind, as temperatures cool, you'll generate more power, and need more fuel. Safe tune, good motor.

Enjoy the boost :beer:
