130mph trap rpm?

[325DR]

Just wondering what RPM you guys trap at around 130. Please post tire height and rear gear ratio. Thanks.

My brother is running about 5800 rpm @ 133 with 28" slicks.

Depends on if your converter is locked in 3rd too.

Here are some calculators on hartline's site that calculate the rpm. From this link there should be a menu to get to the gear ratio calcs.

Is that locked or unlocked? Is that with a TH400? What convertor? And does he have a 3.42? Thanks.

Trap at around 5900-6000 RPM...stock 3:42 gears...28" tires...AC "N" stall nonlock conv..200-4R trans...this is in 3rd gear...

What stall did you purchase and what does it actually stall to (at both 0psi and when you launch at x psi)? Thanks a lot.

It's called an "N" stall...think it's supposed to stall around 3800...popular conv when using the 70GTQ turbo...

What boost/rpm do you leave at and what kind of 60' do you get? I have a similar combo to you. Thanks again.

You won't be able to tell much from my 60fts...they suck...the tires break loose a little as soon as I hit the transbrake...but I leave at anywhere between 7-10 PSI...1.55-1.58 60fts...I did manage to get a 1.51 with this combo leaving at around 10 PSI but haven't been able to do it again...track must have been prepared especially good when I did that...I'm currently working on some suspension changes to remedy the problem...I should be in the 1.4's...

Gotcha. My convertor is loose and I am driving through it (130 turning 6500rpm) but it leaves hard (consistent low 1.3's). I dont mind sacraficing some of the 60' if I will end up gaining more on the big end of the track. Just looking for the right convetor so I was thinking of goign with a l/u unit.
