Running 750cc (more like 740) on mine with only 250whp and idles smooth. full boost 15psi gt2510 with 70% duty cycle rb20det

Refresh Block Crank Collar Arp Rod Bolts Arp Head Studs HKS Gt2510 Apexi Filter Mishimoto Rad N62 Maf Walboro fp 750cc injectors Nistune Fmic 3" straight back except elbow Hallman Mbc set at 15psi 3.96 ring and pinion 2 piece drive shaft ..... and a slipping clutch

same thing happen to my friend in honda. though pvc and catchcan setup overfill and messed up got into intake. so detonated, blew rings and pistons

11.80 is still really low. what is current reading at idle from battery ? it should be around 14-14.5. also when you turn on wiper, vent blower, and headlights how far does it drop. it should not drop below 13.5. if it does alternator is bad.

the apexi thing is i believe a exhaust control valve Make it loud or quiet
