[QUOTE="decipha, post: 16117289, member: 74327"] very nice setup should make 325rwhp on engine @18lbs you should make 650rwhp easily and safely I would not recommend any more on pump gas at that compression if it makes more power than that then its probably too advance and needs the timing backed down a touch BE ABSOLUTELY SURE your tuner knows its a HIGH COMPRESSION 4v. The 4v engines DO NOT TOLERATE compression at all!!!! Someone with no experience with high compression 4vs specifically could be in for a very bad day. I have seen naturally aspirated 4v high compression engines in marauders mach1's and cobras detonate at only 16 degrees NATURALLY ASPIRATED. If I were tuning it Id command 14 degrees at peak torque 0 boost / 0 vac and 8 degrees at peak tq at max boost. 11 degrees or so at WOT above that and if the power isn't there creep it up carefully and slowly reading plugs all the way. Make sure the tuner keys-off at 7k rpm while making the pull to read the plug correctly. Prob best to use cyl 8 as its typically the hottest. [/QUOTE]
