Title says it all. Have a Yank SS4000 2.6 STR Torque Converter and 3.42 gears in my 01 Vette. Have a 100 wet shotand sprayed only 2-3 times and althought my tranny is OK now (stock tranny) it will break soon and I might be getting a Level IV RPM Tranny soon. While my car is up there I was thinking maybe I should swap my SS4000 for a smaller stall?

Which one and why?

The SS4000 is cool, but I am not at the track that often and kind of want a lower stall on the street. I mean the 4,000 is great, but a bit too tall for me for everyday driving and bursts of speed.

Yank has (2) specficied nitrous converters, but who knows?

-Might also get Hardended output shaft while it is out.

Thanks

i would go with a 3600 to still get full benefit and is rpm in lewisvlle building ur trans and also is that 11.42 with the bottle in your car?

 

Pro Yank 3600 extreme converter

Btw you've got a pm

[SIZE=2]RPM Transmissions is a vendor in Indiana that builds a lot of trannys and all love them. 11.42 at 122.58 MPH was NA.

RPM does good work and did most of my work, heads/cam/TC/gears/etc etc etc

I ran 11.10 at 124MPH on the bottle in 90 degree heat, haven't sprayed in the cool air yet. That was one of the few times I sprayed.

I should be in the 10's with a beefed up tranny spraying out of the hole and THROUGH the shifts which I don't do now!

Here are the 2 Converters for Nitrous from YANK

Nitrous/Blower Converters:

PRO YANK 3400 EXTREME 4L60E/4L65E
258mm, Posi Lock-Up Clutch w/Kevlar Linings, 6 bolt mounting lugs , lightweight billet cover, 3400 stall, 2.70 STR

OR

PRO YANK 3600 EXTREME 4L60E/4L65E
258mm, Posi Lock-Up Clutch w/Kevlar Linings, 6 bolt mounting lugs , lightweight billet cover, 3600 stall, 2.30 STR

 

I had Pro TRQ build one custom to my set-up. Car weight, power, tire size, and tranny, gears, and amount of shot!!That way it was just right!!

 

ttt

Thanks guys

Sould I get a new converter??????? Like an SS3600 or the nitrous 3600 equivalent

OR

Upgrade to Bigger Gears, like 3.73's for my existing 3.42's?

 

I run 3.42's and a tightened TCI SSF (34-3600) in my A4 T/A. I had Kevin Winstead at TCI hook me up. I am thinking of dropping to a 3.73 gear with the same convertor. If I don't like the results I will then install the other SSF 3800 that I have to bring the RPMs back up where I want them on the launch as I believe the 3.73's are going to tighten up the launch RPM some. Hope this helps.

PS-It runs 10.97@125 with a soft 1.62 60-ft. time as I am still tuning the progressive controller.

 

Thanks for the replies

 

I going to be switching from 3.90's to 3.42's along with switching from my PT4000 to the PY3600. I'll post results once the PT4000 sells and I can get the car back together

Thanks I am interested what I should do??

Those Nitrous converters are $895 and the YankSS4000 that I paid high dollar for, went down quite a bit as Yank lowered all their prices and sell direct now.

Thanks Guys

 

11.42 was all motor and with my SS3600, with the SS4000 and nitrous I went 11.10 at 125 MPH and didn't even spray out of the hole and it was 89 degrees

 

I'm running a Yank SS4000E, and it's taken everything I can throw at it, workin great with a 300 shot, will see how she does when I change my nitrous setup and up the jets!
