Torque Converters, we need better

[GDNF2ET]

I don't understand why the big turbo automatic DSMs have to have a 50 shot to spool at the line ? These re-stalled stockers aren't getting it done...Take a look at the turbo buick camp, you buy a turbo and match it to the stall that will make it work..Not the one size fits all BS...We should be able to find a proven company to give us the stall we need..

try ipt transmission

ATI may have a solution.

The problem is the torque curve. On a 2.0 turbo motor it has to have a much larger difference in slip between low end and top end than what the bigger motors need, and that is the tricky part. The torqiuer motors can blow through the low end of a tighter converter a lot easier than a less low end torquey motor. Why yours is having issues, I'm not sure still. There are still more things to try, but it seems like it could benefit from being just a hair looser. I think my converter would stall up your turbo no problem, but unfortunately that's not really a realistic option. Since IPT is who did your current one I'd hit them up first, I'm pretty sure they keep records of what they do to who's, as they had a record of mine. Find out if they have any insight and maybe give Hughes a call and see what their opinions are. Other than that, I still think we may be able to get it through tuning and playing with the cam gears.

I called IPT and they didn't have a record of what was done, but they said to check the flash stall and give them a call back and they would work with me on it...I was referred to Protorque converters by a buick vendor and he told me that the nitrous shot is the best option out there right now..He said what is needed is a smaller diameter/high stall converter, and the market just isn't there to do it...He said the Precision converter that was offered a couple years ago was the best one for us, but they were difficult to build and didn't sell well....I called Precision this morning and they said they will call me back with an answer of whether to build one again or not..
Hey Dave, maybe after the MIR event this weekend we can work on it some more ?

, at least there's someone else out there like me.

Well Precision still makes the 2G 3 disc lock up converter and a local here did the 1G to 2G swap so look out on the boards when he goes back to the track and kills the 1G trans setup. He made a full pressure shift box that uses the stock shifter so it's totally kick ass and an easy plug and play.

No one will touch our converters since most DSM owners are brainwashed to buy expensive restalls. I've talked to all of the big makers, the only ones that don't make one and will was Edge Converters and West Coast Converters ( the owners are brothers ). I stayed away after seeing a ton of complaints and how those companies handled them.

Don't bother with the IPT stock restall converter, I've had 2 already and they don't mod it which is why they don't know what was done to yours. There is a shop that will do a custom one but I'm waiting until this 2G swap guy goes to the track 1st. If the 2G bombs ( it won't ) I'll do the custom 1G converter and get back to everyone on who it is and how it went.

Are you talking about spooling your 16g? If thats the case I'm just gonna do a swap now. I was planning on having fun with this auto thing until my last step was the swap.

yeah, go ahead and swap, that stuff is worthless, sell it all to me cheap, I could use a spare 2G AWD Auto drivetrain

GDNF2ET is trying to stall up a 35R.

The evo 16g was a blast with the IPT converter, brake boosted near 20psi once, the 35r is another story.....

and the 35R isn't fun?

 

[420a-t]

haha same with me. I could stall up to 22psi on my evo3 and cut 1.7 60'...but now, it looks like nitrous is my only hope with a holset and my re-stalled converter.

 

[scottr126]

Why not use nitrous? Its fun! Seriously though there is nothing like sitting at the line and knowing that as soon as you let off that brake you are going to be almost instantly at full boost.

This is Precision's response thus far;

They'll end up sending in any core and it will turn out being different. We just can't take a chance making something where we get blamed for the industry having parts swaped for different transmission parts.

What size 35R are you using?

 

[HighPSI TSi Guy]

It's a bolt on 35R. Made a lot of progress tonight. I tweaked the tune a bit and was able to get it to stall up. The converter is still a little too tight at 3000 RPM for a 2.0 though. Really needs a billet or a if possible, a further worked stocker. Got the IPT restall verter to stall to 4500 RPM tonight, but it's still taking a while. Have some other things to try that I think will make it better. We'll see.

How did you do it? Did you pull timimg? How much boost is he able to build at 4500rpm?

It was making 15+ PSI. And it was a combination of a lot of different things and several hours of testing and tuning that made it happen. What it came down to was pretty much a matter of getting every little thing perfect.

I have no problems with my Level 10 Billet converter, 4500 RPM stall.
I have built as much as 30 psi with a 60-1 and T3 .82 a/r hotside on the line. It doesn't do much good when you sheer the rear axles off either.

If you can leave with 22 psi+ there shouldn't be any issues unless it is due to poor tuning. Poor tunes ruin drivability and can severely complicate launching. I have pulled 1.5x 60 fts with 22 psi launches on regular radials with a welded center diff. If your center diff is not welded, your trans will take a dump at that performance level to begin with.

Although not everyone is willing to spend $1200 for a converter. I like stuff that works so its well worth the money.

 

[Car Cannibal]

Didn't know Level 10 offered a Billet Converter, thanks for the tip.

Did you run the stock 3 bolt rear axles when they sheared off at 30psi??

Do a search of Level 10 on this board and on turbobuick.com before considering..

I'm glad its working for you 4SFED4 and thanx for posting..

 

[4SFED4]

I sheared 3 bolts as low as 20 psi with drag radials, the 4 bolts give up a little past 23-24 psi. Most of the time it is the driver's side shaft.
