Default Re: Where Do We Go From Here?

Hey tri_zombie, thanks for taking the time to post all the work you had done. I know I asked a lot of questions, I'm just really impressed with your car and wondered what it would take to duplicate, or at least come close to, your performance. Now I know it takes a bit more than just a big crank pulley, headers and exhaust (Those are mods I don't have).

As for the discussion about shifting into 4th just before the finish line, what would people suggest? If you want to hold 3rd gear, you would have to let off the throttle a bit to keep from shifting at redline. Good luck doing that and not let off too much, slowing you down.
With our gearing, a 26" tire and a rev limit of 6200, the fastest you will go in 3rd gear is just over 111 MPH. At 6300, it's 113 and 6400 (our engines supposed max RPM) it's 114.8. So I guess if you upped your rev limit to 6300 or 6400 you could keep from shifting into 4th.

But the problem I've found is I never hit my rev limit at the track. I believe my tune set it at 6200, but none of my datalogs show my hitting it. Hell, my car always short-shifts first gear. I'd be lucky if it even gets to 5800 in first gear. Second gear is a bit better and I've hit over 6100 when shifting from 3rd to 4th. I don't know why this is. I've read here on the forum that others do hit their rev limit when drag racing. Don't remember who posted it or whose tune they have.

And the last time I had my car re-tuned, I completely forgot to ask to double check my rev limit or ask for a possible explanation as to why my car short-shifts.
