<BLOCKQUOTE class="ip-ubbcode-quote"><div class="ip-ubbcode-quote-title">quote:</div><div class="ip-ubbcode-quote-content">When adding a supercharger of any type, does the fuel octane rating have to increase? Meaning, you cannot run regular unleaded in your H2 after installing a supercharger??? Also, if the answer is 'yes you must run higher octane' then what is the recommended octane level for a supercharged H2? </div></BLOCKQUOTE>
Actually, on the H2, we had Magnusun and Allen Nelson make a tune for 87 octane fuel and it acutally runs good--and even with 8.5 lbs of boost. I have a 91 octane tune that I may use if gas comes back down to reality, but I am interested to see the power difference between the 2 which I suspect is rather small. The main reason to run the 91 or higher is to try and avoid detonation.
