red347

N/A = 10.68 @ 122. 150 shot = 9.74 @ 137. The car has been lightened for this season by 106 pounds, and if all looks good and it will hook, I want to step up to 200 and then a 250 shot.

what type of nitrous kit r u running red347? and what is happening if u pull ur plugs and 1 of them have some black specles on the porcelin?

I have the Wilson Manifolds Pro Flow plate system. 88 spray holes in the spray bars that aim directly into the runners.

Silvered or black spots on the porcelain ususally mean you are starting ot get some detonation. Pull out another degree of timing, install new plugs. If clean it means you have solved the problem.

On the cam question, I used an off the shelf N2O cam form Comp. .683/.696, .286/.296 @.050, 114 LSA. HP stayed about the same, but torque drops way off. Nitrous then compensates for the torque loss. Even though N2O is rated in HP, torque is probably 3 times that number.

only 1 of my plugs have some specles on the porcelin, but it's not black it's some kind of different color and there's not many specles, just a few. is that still a sign of detonation? and if so, what would happen if u left the timing where it was?
