The Truth about PI converters

[PWR_Justin]

Well in a recent thread someone said that PI just bends the stock fins to create the stall in their converts, I'm just here to state the facts about really goes on insided teh PI converters and how unique they really are.

1. PI uses a 245 style core, the only company to offer this, so we can offer more than 25 different setups for any combination that our customers need or desire.
1. PI torque converters can be equipped with STR as high as 2.53:1, an impossibility using a stock Mercedes torque converter core which all of our competitors use.
2. PI offers an unconditional warranty and free stall change for 2 years.
3. PI Mercedes torque converters have custom made parts and only reuse 1 part from the original torque converter while our competitors just modify the stock converter and charge high prices as if it was something special.

PI also uses a different cover for each stall, There is no way to bend that. You can look at the marks int eh cover and the angles of them tell the whole story. Each converter is built per specs of the car, weight/tq desired stall speed. So ever cover is going to be differnt for different cars. Hence, a 3k stall converter for a twin crew car making 600ft/lbs would only be around 2500 stall in a stock r/t the same weight.

Just thought I may clear the air sence some recent posts reflect very wrong infomation

4k stall cover


3k stall cover

uhm.....playing devils advocate here, I don't think PI was specifically referred to or even implied in that post.

[PWR_Justin]

do any of the companies that we purchase torque converters from like Edge, Pro torque or Percision industries bend their fins... I thought these companies make their own torque converters and dont reuse stock ones.

What?????????????
They take a stock converter and bend the hell out of the fins...one uses a friggen cold chisel to bend them over, judging by the tool marks. Hmmm, how consistent do you think that is , breaking all the furnace brazing.
Edge does SPOT weld some of it back together....how do you think that effects balance?
Oh well...if all are happy with their selections, that is really all that matters.
Next subject.

Seems fairly specific to me, enough for me to have to answears questions about it all day long anyway.

We had that 4k stall opened up a few weeks back to get tighted up a little by a local company PTC I'll check and see if anyone took some. If not I will ask PI for some when they redo my stall.

So what is the procedure if I want to send my PI 3600 back to change it a 4200 ?

What this guy said.

I asked for it to be orange. they are all normally pink unless you ask for a different paint.

The main difference is the angle of the imprints on the front cover. Which you can see are a lot more slanted on the 4k vs 3k stall. This isn't something you can "bend" its a different part for each stall.

True that, outside pics mean nothing. Bumps, ridges, mean nothing.

Unless the overall sizes (Diameters) where different. Smaller sizes raise stall.......

It's all so clear now.

I believe those dimples are for anti-ballooning... or distortion of the outer cover under pressure.
