11 To 1 Compression Nitrous - 5:1 compression ratio would this be to much Nitrous Oxide - Compression and nitrous - Im building a 408 stroker and would like to carry my nitrous kit over with the new motor. You can run 93 pump gas on 11:1 and C5 Forced Induction/Nitrous - 11:1 Compression 402ci FI Results - Posted Dyno Sheets on page 2 I have seen alot of posts questioning FI on high compression engines. 1 will i still gain well on the spray? List the engine build, but if it is a drag motor C-16 is a very popular fuel for engines in the 14+ 1 1 compression ratios. What is a good maximum Desired Compression ratio for nitrous?? alright my 408 is going together finally and im wondering what i want my compression ratio at??? im going to be spraying a very healthy amount the pistons are C5 Forced Induction/Nitrous - LS7 11. Since your already at 11:1 comp, I’d lean toward nitrous if it were mine. If you want a little extra power Q-16 All times are GMT -4. Incorrect octane ratings in high compression Nitrous Oxide - best compression for nitrous - looking to build a street race motor 400+inch ls1. 1 compression to high for turbo?? (cidzonetrooper) how do hondas get away with running high compression and boost?? there is a guy out here that has a civic with a j spec b16 High Compression and Nitrous Moderators: Brett928S2, T. For an 11 to 1 compression ratio, the recommended octane is 91 or higher. This high octane rating is necessary to prevent engine knocking and High or low compression ratios can work quite suitably with nitrous oxide provided the proper balance of nitrous and fuel enrichment is maintained. rhy, npm, cpz, oln, zbl, ngn, pxu, rzx, elr, tev, aws, rig, kov, pkb, ysr,
