hi i have just brought my first erst and it has a in car adjustable boost what is a safe setting for a standed engine with a Mongoose 2.5 exhaust and a front mounted intercooler also what is the purpose of a boost valve why would u want to addjust it why not leave it at a high safe setting?????
as u can tell i'm new to all this turbo stuff

Without a chip and setup, you would look to be running 7-8 psi to be safe

SafeChav

The idea of it is so you can turn the boost down to save fuel etc and make the car a bit more driveable.

Keep it low until you have a set up, in car adjusters have a very dangerous potential

SafeChav, if you turn the boost down it's still gonna use the same amount of fuel that it's set up for, so it'll then be overfueling ?

get the in-car adjustable cack to fook, set it to 7psi and then get a tuner to set it up properly and leave it alone, it'll only end in tears otherwise!

Ad4m RST

Agree with both, just get it to a tuner as soon as you can. Setting it to 7psi should be fine just hope the previous owner didn't have it fuelled for alot more.

Whatever you do don't go messing with it, most tempting thing in the world when you've got in car boost control just to whack it up when a porsche flies by

cheers for all your posts.my plan is to get a chip and get it set so i know everything is ok.i have even been thinking of getting rid of the boost just so it dose'nt tempt me like ad4m rst said

SafeChav

vroooom ptssssh depends whats been done to it to cope with high boost fuelling, if its just got the KE set up running it shouldn't overfuel on low boost......

I think

Ah well even if im wrong i dont care because its EFI for me

reality

i think you'd struggle to blow it up as you'll hit a boost cut.. unless it is chipped.. then who knows!

SafeChav

Boost cut is never good for the turbo or head gasket though

steven botes

leave it alone till you know what your car is set up for!
eaisest way to impress others when cruising and break shit

slimwynn

is there any good tuners by me i'm from shrewsbury in shropshire.

slimwynn

so if i have my car chiped and have a actuator-34 fitted what kinda boost could i have with a standand speck engine,no performance cam as yet

reality

You dont want a -34, you'd want a -31.. your tuner should set it up to about 1.0-1.2 bar boost.. for about 185bhp

slimwynn

so when would i need
a -34 when i get a upgraded turbo?

reality

You never need a -34 on a road car..
