Hey I am in the processing of building a h22 for boost 9.5:1 compression JE pistons 89 bore goldeneagle sleeves swain tech coatings etc. I plan on running 10lbs of boost JRSC. AEM standalone 550 injectors. Hondata intake gasket fluidyne radiator, engine oil cooler. With out the luxory of an intercooler I am looking to run either 101 or 104 octane unleaded. Any ideas on how much timing I will be able to run. I know for pump gas 91-93octane hondata uses the generic .75 deg of retard per pound of boost for their boost tables. What about for 101/104 octanes. Thanks in advance

 

Id think with the good fuel management, you could run 10psi on a 9.5:1 on 91 octane..maybe not as much timing as you like tho but it should run strong.
