Hi guys, I have a 86GN with a stock block & crank. Eagle rods, JE pistons & a Comp cam. (duration @.050 212 lobe sep 110. It has stock heads,( non ported) intake ,throttle body & MAF. TA Per. headers, Southeast Turbo 3" DP with a RJC racing 3' exhaust. (with cut out) A PTE 6262 turbo & PTE stock location intercooler. Turbo Tweak chip & injectors. A RJC Racing Power Plate. It also has a TR Custom Parts Big Mouth cold air kit with a 4"/9" K&N air filter. The trans is also stock with a shift kit & a PTC 10' converter. Stock rear with a posi unit. What kind of ET's am I looking at with this combo. How fast can I go with the stock MAF, throttle body & plenum? I know these are limiting me, but how much? This car is going to be on the street 98% of the time with 93 octane. When do I need Alky? Thanks in advance for pointing me in the right direction. Your help is greatly appreciated.
