I MADE 558.6 ON 104...NO CAMS OR NOS....THE GAIN WITH THE MIX IN MY OPINION WOULD BE INSIGNIFICANT....IF I AM WRONG THEN I AM...OH WELL

i wouldn't risk running leaded gas, but that's just me. it will screw up your o2 sensor.

I've ran leaded fuel in my car for many years now with no problem. But if you have a wideband sensor intalled then I suggest you remove the sensor before starting up the car with leaded fuel in it.

why would it hurt your engine?
The only thing it should hurt is cats and maybe o2 sensors after a while. But when it comes down to it, what would you rather replace?
A $50 sensor due to leaded fuels every few years or a new engine due to detonation?
With that being said I run race fuel in my car all the time with 0 problems. Matter of fact I have a 1/4 tank of C16 in it right now to play this weekend

Honestly though it depends on your set up , If you are still on stock twins, it is likely you really dont need it. You wont be pushing enuff power or boost to get it to detonate anyway unless you cant tune for shite.

Besides burning out the o2, I love pumping the high octane. I've notice that it makes my car idle soooo much smoother, not that it doesn't already. Good stuff :gapteeth:
