I have been toying with the idea of getting about 10 gallons of VP race gas. Would it be worth it? Of course I mean for when I go to the track (Grove Creek doesn't have race fuel at the track so I have to buy it at a local exhaust shop).
I have a CAI, a Magnaflow Wide open single 3" in--> dual 2.5" outs -->-->, 180* t-stat drilled 1/8" holes in two spots (now the engine runs at 165-170 everywhere but at a stop -then it'* about 195-200), removed MAF screen, Taylor Spiro Pro 8mm wires, NGK TR55 V-power plugs (been thinking about going to TR6'*), 2 bottles of JB water wetter ($18 worth), and I never put anything less than 91 octane in. Also, in the next month I will have ported and polished lower intake manifold, exhaust manifolds ported , and the heads ported with all ports matched.
I am guessing I will really reap the benfits as my car has serious knock retard (I experience extremily noticeable KR about 95% of the time I put the pedal over 1/2 throttle). I just wish I could get my car hooked up to a scanner to see if there are any codes -SES light has never come on so I haven't been too worried, and can't really afford to unless I really am having problems.

TIA,

Absolutly!

What is the race gas rated at out by you?

If you experience severe knock retard as you say, then it will make a HUGE difference. If you weren't getting any knock retard and were running full timing, I would just run regular or midgrade in it. But since you are experiencing severe KR, you should notice a HUGE difference with race gas.

Remember, any gas above 104 octane is low-lead, not unleaded, and some 104 is low-lead also. If you don't have a catalytic converter you should be fine (it looks like you don't) running leaded gas, but if you do have one it causes a problem.

Well, if you can find high octane unleaded, or even maybe low lead, go for it. I would NOT run leaded race gas in your car, unless you want to change out the O2 sensor on a regular basis.
