How Would I Increase Top Speed?

Jeep Trick · #1 09-09-2009, 10:34 PM

Given my current configuration what at this point is holding me back from going faster? Obviously not power.

So is it something that has to be done in the TCM or can I do it in the Predator by bumping up the redline?

Can it be done in a CMR tune?

I always assumed it was done in the TCM but am not entirely sure.

Have you run it at the track yet?

Sometimes the cmr tuners forget to raise the limiter

Vortech forgot on mine

Unfortunately not, have had a lot on my plate lately. There was a death in the family among other things

I really want to get to the track but still have an issue with the bushing and my mechanic has been to busy to get to it. Hopefully next week he can get me taken care of.

I am registered for the Miami Mile on Oct. 11, thus the reason for the question

With little time left I would at the least get a Diablo tune.

Are you referring to top speed?

Sorry just read the title, to increase top speed you would have to change the gear ratio in the rear and front diff. I believe we will gear out at 172 regardless of rev limiters.

bumping up redline can be bad unless the motor is made for it...

no there no such thing as gearing out without a redline

what if you set it to 10,000

Paul did Vortech revise it for you?
