It's not like premium fuel hurts the car.

 

Your changing the detonation times, so unless you are tuned for your engine to detonate the fuel properly for that gas then it's a waste of money and you aren't going to pull a better 1/4 mile time.

Also 35 PSI is way to high, you'd want to actually lower the PSI in the tires, esp the front to help you get better traction.

 

Mike (chibiblacksheep) is right, if a car requires regular gas, then you will not see performce gains with a higher octane gas...but, Quartermain NA SS is also right, it does not hurt a car to run premium when it requires only 87.

Now, I was told by a tech at the Chevy dealer that with the VVT, it is possible that a higher octane gas MAY give my car more power...but he said I would never feel the difference because it would be a gain in the neigborhood of 1-3 HP. And i've run 87 octane, and 91 Octane, I can't feel any difference.

 

I run 34 PSI in the back and 26 in the front when racing. You want your fronts to be a little lower PSI to have move tire on the road, you'll hook up better. You want your rears fully inflated, makes it easier on your fronts to pull the rest of the car and also helps the front tires hook-up more quickly.

 

cant wait to see more numbers
