and1c Posted December 20, 2016 Author Share Posted December 20, 2016 Stock converter used to lock up at 2200rpm for us, worked great launching as TT. But launching a single turbo with a stock converter is awful. That's the advantages of having a high stall. Although the stock torque converter with our setup works great on the road. Power delivery is alot more predictable and also more smooth. unlike it was with the 3600rpm hi stall. What's your setup Chris? the one in your signature? I am guessing you are seeing boost at quite low RPMS then? Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted December 20, 2016 Share Posted December 20, 2016 What's your setup Chris? the one in your signature? I am guessing you are seeing boost at quite low RPMS then? Stage 3 built SRD auto Stock torque converter Precision 6466 turbo SRD turbo kit Hypertune intake TRD diff etc etc... Makes full boost circa 3600rpm. 654rwhp on V-power 708rwhp on E70 Quote Link to comment Share on other sites More sharing options...

mellonman Posted December 21, 2016 Share Posted December 21, 2016 I take it that's in top gear ,ie a motorway pull ? Quote Link to comment Share on other sites More sharing options...
and1c Posted December 24, 2016 Author Share Posted December 24, 2016 The 3800 stall certainly adds an element of craziness, especially on kickdown but I like it more and more each day! To be in the powerband so fast is a massive bonus. If I was daily driving it I wouldn't be anywhere near as happy though I would still prefer it vastly over the stock TC as it just bogged down from a stop eg traffic lights until it was making boost. Hopefully it will help a lot at the 1/4 mile which is my main requirement.. Quote Link to comment Share on other sites More sharing options...
Milo500 Posted December 15, 2017 Share Posted December 15, 2017 (edited) The stock TC flash stalls to 2, 000 rph , I think the 3200 stall would be best suited to a street car , also with the higher stall I hear the lock up plays up, iirc its to do with motorway cruising where the TC is still slipping / not engaging 1:1 ratio so you need to manually set / switch the lock up or you will cook the box from all the extra heat . *BUMP* Hi, I have been to pod quite a few times and am having trouble with getting off the line...I am looking at a 3200 stall as the car is used on the street, but no longer a daily. It is turbonetics tnx 45/64 with a stock box (hopefully soon to be shimmed by David p) with two large coolers, running just over 500 at the crank. The only thing that concerns me is this excessive heat most people say about crusing on the motorway (which is what I would do for a few hours to get to somewhere like pod) ... at what point or what stall does it start to start slipping when crusing at like 70-80 ish? Will a 3200 stall lock up at that point? Or if not is it better to drive with overdrive off so it is locked up? Thanks, just trying to ignite an older thread and get some more info before I look at getting one.

supradanturbo Posted December 16, 2017 Share Posted December 16, 2017 If you are serious about drag racing with an auto. You need a high stall. I have a pi 3600 stall. I am planning on going for a 4000 stall in the future to fully get the turbo into boost on the line. Quote Link to comment Share on other sites More sharing options...

Thanks, just trying to ignite an older thread and get some more info before I look at getting one. I have 3 large tranny coolers and the only time temperatures even approach getting hot (100 degrees which isnt hot) is in heavy traffic going uphill, stop start. Its perfectly fine on the motorway, I leave overdrive on and there is no slippage noticeable over 70 although my driving style has probably adapted to the hi stall. OD off doesnt lock it , that can be done by installing a manual switch but I have never felt the need for that as it drives fine. OD off just stops it going into 4th gear, eg it remains in D. Not good for fuel or relaxing cruising. I cant really tell the difference from stock now apart from instant boost off the line, I highly recommend the titan one.

auzzam Posted December 16, 2017 Share Posted December 16, 2017 I've just got one big cooler on mine, 3800 it's absolutely fine. I think you spoke to my cousin Saq at santapod. I actually own the silver supra that was there that day. I've driven it on the motorway in the heat and had no problems whatsoever and Saq's run them on his last two supras without issues.

Krister Posted December 17, 2017 Share Posted December 17, 2017 I have a PI3800 rpm stall on my Aristo and it locks up fine during highway use. I think lockup is mainly controlled by the speed and not rpm so lockup works almost like stock on light cruising and motorway use. Quote Link to comment Share on other sites More sharing options...

Milo500 Posted December 18, 2017 Share Posted December 18, 2017 Cheers for all the info I am looking at a second hand pi3200...will it give me much of a befit over stock on the drag strip? As it's only roughly 1k over stock? Quote Link to comment Share on other sites More sharing options...

Milo500 Posted December 19, 2017 Share Posted December 19, 2017 (edited) Yes! Depending on your setup I've got a tnx turbonetics, med to large turbo, comes on at about 4k-4.5k ...so will 3200 make enough of a difference? As I still want to drive it comortally ok the street, and don't want it slipping too much on the motorway etc...I've allready knackered one box haha Is anyone using a rev limiter like a bee r, or one incorporated into their standalone to get some more boost off the line? As if that works then I could go for a 3200 so it's ok on the street, but still get good boost off the line at the strip?

and1c Posted January 13, 2018 Author Share Posted January 13, 2018 The stalls that they are advertised with are not always 100% accurate. So 3200 stall may actually be 2800 stall, my 3800 is nearer 3500 being full lockup. With the turbo you have I personally would go with the Titan 3800 rpm stall. But I have not driven the 3200. It works perfectly with my setup and that starts making boost at about 3k so I would suggest that would be needed on yours to stop it bogging down. Regards your gearbox failure, I would look at getting it uprated or a Titan stage 2 box in there for max bulletproofness! Upping the line pressure of the stock box seems to be a very worthwhile and cheap mod, I think David P does that or has details on it, and also it is on Supraforums as a guide iirc Quote Link to comment Share on other sites More sharing options...
mellonman Posted January 14, 2018 Share Posted January 14, 2018 fyi their is a 3400 Quote Link to comment Share on other sites More sharing options...
Milo500 Posted January 14, 2018 Share Posted January 14, 2018 Cheers, I have bought a pi3200 off of a guy on here, and am hopefully going to be having David p shim it etc so ut can hold some more torque than stock. The converter should lock up on the road, but wondering if it will be enough stall to make a big difference om the track...what is the stall of the stock converter?
