I ran NOS octane booster. The stuff does work a bit.

I have always run standard Autolites in everything and never had an issue.

Hate to break your heart but it prob doesnt. The main ingredients in that pint of octane booster are Toluene or Xylene? I think it is. And you need 1 gallon straight of each, to raise ten gallons of 91 octane to 94 octane. So a pint aint gonna do shit, haha.

Go to your local paint supply store and pick up a 5 gallon drum of Toluene.

And ya, additives prob caused the red, or I think rust might do it too... but I doubt you have that problem in a C5

Mix E85 in there or run Torco if you need the extra octane. Im using E85 now to get me around 94-95 octane. Gonna go with Torco to make things easier. Torco does work, seen it with my own eyes on the dyno.

I've run a can of Torco at Adams to keep the Cobra from detonating and it works great.

I have no need right now for the extra octane. I used to use a gallon of xylene before for my high compression motor but its $15gal now. So then I started using a mix of 30% e85 with 70% 91 for a few years and it worked great. When I used the nos it was two bottles for 1/4 tank of gas. I know its not great stuff but I have seen it work to a point. Here in CA its the only one off the shelf that might do something but you need two bottles at least. Also Im only talking about it helping for 1* or less of kr I was seeing. Not like it boost octane enough to to add timing or boost or something like that.

It has a small amount of nitro methane. I think it raised 10gal up to 92 from 91 in a test. I know, not much.

Btw this was just once, that i used octane booster, when i put the ls3 together since the old tune had too much timing in it, like 34*, but i ran cold plugs and the e85 mix. When I did try octane boosters before, they never discolored my plugs. I think the fact that the plugs werent hot enough kind of let that stuff bake on the plug this time.

Took a short drive, gave it a quick wot here n there. Now the ground straps are all white. Wtf? Porcelain is clean, no specks.
