drive pressure question

[jmd025]

Doing some twin tuning, right now drive vs boost is 1.2:1 . My question is, what is an acceptable drive pressure value? How high can it go? What's normal for a 500-600 hp twin truck? Is there a max?

Yes I've read that thread a dozen times..... my question is, is there's max drive pressure value to attempt to stay under....which is not addressed in that thread unless I keep overlooking it.

Thanks, josh

Never more than 2:1..closest to 1:1 the better...up to 1.5:1 is acceptable.

Your 1.2: is great.

So I shouldn't be concerned with dp in the area of 80-90psi as long as the ratio stays 1:1 ish?
