I need some info on the TP series.
What is the SE of these verters:
4000
4200
4400

Also if I had a TP4200 behind a 380RW setup and then went to a 410RW setup would it stall alittle higher?Lastly,does the TP 4200 work well with 4.10's...

Colonel

My best guesses follow...

5500
5700
5900

If the power at 4200 was increased then yes, it would increase the stall speed accordingly. If the power at that RPM was still the same or less then it wouldn't (and that very well could be the case.)

4.10s? Yes.

I have the TP4200 from my old JPR S1/224 setup that stalled to 4200 and a SE of 5500.

I think I have found my new verter Steven.I have about 15RW more at that given rpm vs my old S1/224 setup so it should stall another 200 or so and give me just bit more SE.

Thanks.....

Colonel

Cool. It's hard to go wrong with a TP 4200.

I probably wouldn't expect 200 RPM more stall out of 15 RWHP more at 4200. 75-100 would be my guess.

Thats fine,4300 flash on a setup that peak tq's at 4600 should be good.
Plus the much better SE from the Yank...

5800-5900 rpms with mine. I also run 4.10s with 26x10 ET Drags and a good suspension is a must with this combo. Hold on when you let into the throttle with the PT/4.10 combo

Yep yep, same here. I had the 4400 when my car was stock internal with 3.42 gears and now with H/C with 4.10 gears. One thing I am wondering (colonel?) is when the car was stock internal the sweet spot seemed to be right at about 2500 rpms, but with the added power I am wondering if I would benefit more stalling it up closer to 2800-3000??

If I see 5700 on the upshift I be a happy man..
When I had this verter in my cam only setup it SE at about 5700,I think its gonna be just like a 4400 with my added power..

Hopefully I wont lose 34RWHP like I did w/the VIGI

I'd stall that converter at least to 3000, traction willing of course.

I tried a tip that Mike Hoffpauir told me back in febuary on launching the PT4400 and 4.10s but it would only work if the track was DEAD HOOKING. He pulled his best 60fts. by leaving at 1800 rpms letting the converter flash some,so i tried it and spun hard doing it lol. Leaving at 2400 rpms the tires would plant and go pulling 1.51 60fts. but leaving at 1800 rpms the car would leave a little sideways off the tree but still pulling 1.53s. I think if i could ever get things settled down at the launch then the 1800 rpm drop would be the key to 1.4x 60fts. like mike was pulling.

The higher i went on the rpms the worse my 1/8th mile ETs got but i still pulled the same 60fts. compared to 2400 rpms. What do you think about that stephen?

Colonel

I think there were other reasons why your 1/8 ET got worse. You 60fted the same due to traction limitations. Your 1/8 ET should have been the same IF all else was equal. It could be that your car was making less power on those runs (heatsoak, weather, etc...)

When I ran a Yank it always worked best with more brake stall?
2400 to 2600 seemed the best.
