I have a stg 3. 330BHP 2wd sapphire using a 500 cooler, 803s and a T34 .63 Mar- m 247 shaft, which actuator would I be best to use in this, the car drives best around 5-7200 RPM limiter and I like power to be consistent, ideally the same power lower down to match the top end, so am I best off with a -34 or -31 actuator to achieve consistent power?
What do you run? I will be mostly on track and drifting

 

-34 on mine m8.

 

Thankyou, how does the power come in and I'm guessing it holds the boost well at that?

Anybody else using an actuator?

 

personally i'd ditch the greens and get greys or siemens blacks with a new chip; see 380-400hp with that spec, might as well get the most out of it

incidentally i had -31 actuator on mine

 

yep am going blacks woz at msd talking to kenny yesterday

 

Ok blacks on my shopping list, can my existing chip run them or be re written? How does the -31 differ in use from a -34 please if both have been used they both must work but what's the difference in power delivery etc?

 

you'll need a new chip if you want to use new injectors, but if you havent got the money at the mo, greens will be ok - you just wont get the best out of the turbo

the difference between the 2 actuators is the lift pressure, 8 psi for -31 and 14 psi for -34

heres a good article https://passionford.com/forum/techni...ifference.html

 

am going to run air to airs as well

 

Brilliant thanks, a -34 then and I'm eventually having air injector and blacks to match, what are the part numbers for siemens injectors for upto 380 bhp as mentioned above? That lot will be plenty for a STD box etc

 

3102 is siemens blacks 55lb

 

Why not ask Stu at MSD?

 

had both and i like my car much better on a -31

 

Always ran a -34 on the t34 LOL

Pete ure a gay boy thats why u like a -31 - nice slow progression on entry

 

....stevie babes ur getting me horned up.....
