So I'm running a 3.54:1 rear with my TKO 5-speed. I know 5 is an overdrive so I can't expect too much there. I do have a good timing light so I'll make sure the distributor if optimized. I haven't checked my air filter - it's one of this giant ovals with the black and aluminum fluting on top that says "COBRA." I'll see if K&N makes one for those. My pipes are the ones ERA uses from a company called Stainess Specialties. I inquired with ERA about what's inside of them for mufflers. They didn't specify other than saying that it's a very good design and better than what you get if you don't opt for the stainless option on the pipes. However, I think it sounds great but I don't need ear protection. Also, I don't want to need ear protection, and I don't think I want to attract any more attention around town than I already do. So I'd rather focus on other ways boost it up a bit.
Sounds like timing and air filter are two pieces of low hanging fruit.
I believe my PI intake and CJ heads should already have a matched port size since they are both designed for each other (right?). But I suppose you could report them both for a better overall airflow design.
Great input from everyone on this. And although I believe I have a pretty good natural/learned talent for keeping this car stuck to the road, I do plan on taking this to a driving school also. But again, I'm not looking to go over 500hp - "just" high 400s.
Given all these new mustangs, cadilacs, BMWs and yes, even Hyundais coming out with crazy power these days, I really don't want to risk embarrasing myself out there!
