Justintoxicated Posted January 7, 2004 Report Share Posted January 7, 2004 16 are too small more than likely, Im running a 50/50 mix 1/2 pump 1/2 race and I only have 19cc domes. Quote Link to comment Share on other sites More sharing options...

sean10 Posted January 8, 2004 Report Share Posted January 8, 2004 Thats a small dome which will give you higher compression. You will need higher octane than 98 octane. Why are you going with such a small dome size? Quote Link to comment Share on other sites More sharing options...
FULL_METAL_JACKT Posted January 8, 2004 Author Report Share Posted January 8, 2004 thought i could get more compresion! but i want to use reg. gas, not race shit. FMJ Quote Link to comment Share on other sites More sharing options...
