Right i got a -31 on my motor which is on its last legs Im going to get another one as per insructions of Mark But i forgot to ask what the differences is between the both?

So any idea? Yesterday i think it was told one comes in with more of a bang?

-3

You can fine tune one of them more than the other

Graceland

which one as i need a new one - the actuator thats on mine is something stupidly

Daveyboy

-31 i think

Rhys

Well Graceland i presume a -31 is better as thats what i been told to get But just wondering where a -34 would be better as obviously there must have been a need to produce it?

gurnE

Base lift pressure is alot higher on the -34 (14psi compared to 7psi from memory, which could be wrong)

You're T34, greys & 30psi aren't you Rhys?

I was told -34 is worthwhile on anything stage 3 or over

10psi to 14psi i think....could be 14psi to 18 psi tho LOL....can't remember off top of my head.

T34 -34 is required IMHO makes it nice

Rhys

GurnE supposed to be running over 30psi but currently car is only going to 25

Well Mark said -31 even for the boost so im getting one of those, as he knows what to do with the engine. Maybe its down as said above u can fine tune it more?

Just to contradict Dingly, go for the -31, as combined with the correct jets in the amal valve and boost map in the chip, it does exactly what you want it to . Just listen to your tuner .

gurnE

Well, I'd always say follow the advice of your tuner.

I went from a -31 to a -34 but also went to greys,T34 and boost controller all @ the same time so couldn't tell you if the actuator alone made any difference

Rhys

I am But just wanted to know the difference

Surely you listen to the people that make the turbo

mine had a -34 when harvey did it, so did jay's and my tuner says -34 so

morto

i have - 34 as recomended by stu but dont forget guys the main diff is lift off -34 needs 14 psi before lift will start and kicks you in the backside.. - 31 lifts at 7 and does the job smoothly dont also forget .. no amal valve means -34 with amal valve its up to you..
