As to some of the mods, I thought Jannetty Racing, in Waterbury, CT did some pretty good analysis of what various mods might yield if I recall correctly, so probably worth trying to find his posts, but remember when modding, keep your intended purpose in mind. |
If thats aimed at me its not really neccesary, but thanks. And yes Jannetty did some very useful testing, i posted the link to it a few pages back.
1 7/8" headers gained 14hp peak to peak, and their best gain anywhere on the curve was 15hp.
2" headers gained more but also lost 5-10tq in the lower areas, so its a trade off.
