Need Crazy High MPH? Hey guys,
What is the best Stall Converter to run with a TNT 150 Shot for max MPH??
Im using a TX-Speed Torquer Cam and Patriot Stage 2 LS6 Heads.
I also have 2.73 Gears......
Would a 3600 stall be good?
I want the best possible trap speed possible.
Any help is great!

alot of other info is needed here...how much does your car weigh and what tires are on it? shift points? rev limit? maybe a better question for the auto trans forum.
it's a hard(almost impossible) to pick a converter for nitrous that is perfect on and off the bottle, you usually have to trade off

I would stick around the 3,500-3,800 range too. You'll also want a converter built for nitrous with anti ballooning plates and severe duty sprag, that's usually an extra $200 or so. If your keeping the 2.73s you'll want to look into a higher str too, I would say 2.5 bare minimium with a 3,500-3,800 stall. If your going with a sticky drag radial go with like a 2.7-2.8, that would hit nice and hard out of the hole.
I'm not sure what your budget is but, check out the PYE 3600. It's a real nice nitrous specific converter made by Yank, it's also one of the most expesive though.

Only problem is that TCI sent me a 4000 stall instead of the 3800 i ordered. so now im trying to rethink everything and see what u guys think. the 4000 has a 2.7 str.
would the 4000 work or is it way to much?? I seem to think i should send it back in and get a lower stall.....
Thanks guys!

It depends how efficient the TCI is. When you put a good amount of nitrous to a big N/A converter they tend to slip alot and you blow right through the converter. I would personally send it back for a restall but I have no experiance with TCI converters.

I ran A TCI SSF3500 with my old setup, I had 2.73 rear at one time
stock internals with a big dry shot i was close to going through the 3500

I e-mailed Fuddle Racing, and they recommended a 3400 lockup with my (now) 200 shot (mainly street use) using their Performance Series for about $400.
edit: I also have an A4 with 2.73 gears... cam + spray + bolt-ons

I just ordered a Fuddel Racing 3500 stall w/ a 1.7 str.
John at Fuddel said it would work great from a roll w/ 2.73's but not so much from a stop. Im mainily looking at racing from a roll. So I will try this one out and hopefully it will push me past the WRX I'm racing....
The WRX traps 127-130mph!! So I might need to think about a 200 shot!
First I'll run the car on the 150 shot and see how it traps, then if I need more it will have to be a 200 shot...

With the gears you have your best go at a roll will be from 75 MPH in second gear.
Lock the converter at 95 MPH second gear WOT.
In third gear you don't want the converter locked at WOT until 150 MPH.
The lock-up speeds apply even if you run a non-stock converter, but running a stall like that with your gears will build a ton of heat. Don't be racing with a hot tranny.
If you're racing up to about 140 MPH, then you'll need to tune the 4000 - 5200 RPM blocks of your timing and fuel table a bit to survive a big bottle shot with the increased load in third gear. Pulling a couple of degrees advance and adding a couple % more fuel would be reasonable.
It's not that normal to use N2O for long high-speed roll races, but it can be done. When you get in third gear your piston speed will be changing very slowly, so the tune needs to match that with a slower burn.
You'll also need a cold sparkplug that will not overheat while being under load for that long. I'd use an Autolite AR472 racing plug for that.
If you're not winning by 130 MPH, then I'd shut it down and try another time.

I would love to run a stock converter, but I was told that the car cannot be tunned with the stocker in place.
I'm not really sure?? I was told that going w/ a Torquer Cam from TX-Speed that I will need a larger stall in order to complete the tune......
But, would a stock converter hold 550-600 hp???
