New PI 3800 Torque Converter......

A standard PI 3800 TC will handle 650+ BHP, easily exceeds the stock box limits of around 500. Higher stall speeds mean it will launch in a higher power band. It is stronger than the stock unit.

 

to follow termi's wise words...

 

a 3400 stall took nearly 1/2 second off... soop dog's(?) quarter mile time on stock turbos i seem to remember.

 

this 3800 is more suited to big turbos/drag use because of the higher stall.

 

this unit would tansform a single turbo auto, from fast, to silly silly fast on the strip!

Can anyone tell me:-

Is this a straight swop for the stock item ?

How would this affect day to day driving ?

Do you need to do anything with the standard ECU ?

Cheers Dave.

 

 

Yes

 

Slightly more revs when pooling about, I did not mind running a 3800 stall

 

No, you might want to wire up a lock-up switch to lock up the converter for cruising around to help keep the heat down.

Controls a solenoid in the transmission to 'lock up' the torque converter to stop it from slipping and building up unnecessary heat.

 

Forgot to add that it should not be enabled when using full power too often as it will put a strain on other parts in the box.
