This last part is what is of interest to me and also whats holding me back from the 4.10s or 4.30s. Low 11s with a 3.27 So its possible but would 4.10s be better.Ralph Greene said:BTW there is a guy with a blown 97 Cobra who posts on here running low 11's with 3.27's and TKO. I believe he crosses the line in 3rd. He has less of a traction problem.
As a general rule, the better your P/W ratio is, the less you need big gear ratios. That's because traction rather than power is going to be your limiting factor.RioRed1997GT said:I've done the searchs but so many different opinions to make a sound choice. So I'm hoping this is the ultimate end to it all...
For '96-'98 cars 3.73 is the biggest diff ratio for which there is an official Ford part # for the speedo gear. For 4.1 gears I've heard there's an "unofficial" part # that works but was made for a different car, and I've also heard it lasts a while then self-destructs into a mess of plastic. From what I've heard your best option may be an Abbot compensator.RioRed1997GT said:Thanks guys....I think I'll go 4.10's after everyones imput. My only question is.....is the speedo compensator really only $15??
