With -31 actuators, is there a difference between
them for the different turbos? t3, T34, T4??
Rod lenghts weights etc?

and Is there a way of telling what turbo its for??

Got mine at a Show a while ago, (not used it yet lol)
and i can see 31 at the end of the code number,
but just wanted to double check they have given me
the right one for a t34!!


thanks!

 

they are in different lenghts.

you can alter the lenght by swapping the bit the screws onto the threaded bit.

not too sure on the other Q's.

 

thanks Dave!

 

I saw a pic from Stu (msd) a while ago...you could see three different actuators...maybe he still has it...

 

maybe...standard, -31, -34.

 

or were they different lenghts

 

there are 3 lengths - very short for Escos, medium length for 2wd and long for 4x4.
the other variable though is the length of the turnbuckle that attaches to the wastegate arm, so by juggling the two there are a few combinations that can be achieved to reach the same goal..

 

ah i see. but ultimatly all -31s will open at the same pressure?

Seems a bit of a silly question when i put it like that


thanks Richm!!

 

yes I believe so, only the physical dimensions that vary.

 

dont need to worry about that being wrong now then!

 

8 psi liftoff for -31, higher boost achieved by ECU & amal valve/other boost control.
