How much

[saywin]

How much will running race gas help a totally stock cars performance?

Just running race gas in there, wont do anything, with the stock chip...

You get a chip from TurboTweak for race gas, slicks, upgrade the fuel system with new pump, hotwire kit and adj. fuel pressure reg, then crank the boost to around 22 or so.

Launch with 10 or so psi. Bam, you got a 12 second car!

Hopefully that answered some of your question..

Only if you are getting knock with the stock chip will race gas help...otherwise it will probably hurt performance because the slower ignition/combustion rate of higher octane gas will need to have the spark advanced to get the power out of it...otherwise, the cylinder is already going to be traveling down by the time max combustion occurs.
