oh i didn't realize that you were in a truck...that's a different story then. if you're planning on using a higher octane combined with nitrous then i would definetly stay away from torco, as it will lean you out and you don't want to do that when spraying.

 

how high octane can you safely go on s1?

 

you can go as high as you want, but anything past 93 is just going to slow you down. higher octane fuels are harder for the engine to burn, and if you don't have a way to change timing to adjust for it then it actually does more harm than good.

 

outstanding numbers psi my s3 just came in and i was thinking about getting a p/p head when i throw on the stg3. 355 non hom that rocks.
