could anybody tell me what the boost should be on a standard erst,how much can i go 2 with exhaust,air filter,dump valve,fast road head and saab turbo,not sure if its chipped,how easy is it 2 tell if it is chipped

 

8psi

 

can i go higher than that or should i check 2 c if its chipped first

 

isnt 6 standard and 10 psi the limit on std chip?

 

ive got a bleed valve on it so i can adjust it a bit

 

no! leave well alone!!!!!!

 

u can run 10 psi max on a std chip, take out the ecu unscrew the cover then unscrew the board and see if the chip has a aftermarket manufactuers name on it, tbh ur best bet is to get it set up properly by someone who knows what there doin and dont touch the bleed valve unless u wanna re do ur headgasket and anything else that will proberbly blow up if u wind the bleed valve out

cheers kev

 

with the turbo ive got on it it was only boosting at 4psi with the actuator off the original turbo,ive moved the bleed valve a little bit and it boosts at 8psi now but wasnt going 2 move it any more

 

best get ya fueling checked then matey,you never know

 

surely even if its got a standard chip in it it should b ok shouldt it,might hav an evo7 intercooler coming for it so will check the chip and then get it set up when its all done,dont drive the car at the moment so cant do no damage

 

the fueling will be fine for 8 psi of boost, check to see if its chipped then once up and running get it set up properly and get rid of the bleed valve if ur curious to how fast ur car can go, me and my mate wound one out on a xr3 turbo and the engine lasted about 10 mins wont ever do that again lol

 

cheers 4 the help but what would b the cause 4 it 2 only boost at 4psi without the bleed valve,if i fit a -31 actuator will that make any difference,the turbo ive got on it bolted straight up but the inside diametre of the inlet side of the turbo that comes from the air filter is bigger than the turbo that i took off so would i have 2 get an actuator 2 mach the turbo or r they all the same really

 

i had 12psi out of a standard chip

 

i wound the bleed valve right in and it was boosting at 4psi then wound it out 2/3 of a full turn and it was boosting at 8psi

 

how well did that go on 12psi then and how long did it last,how did u adjust the boost 2 get it up 2 12psi,im new 2 turbos u c bcause my last car was a 2.1 mk2 escort so i only knew about n/a motors really

 

it was only peaking 12psi you wouldnt of held that in the high gears.
mines peaking 12/13 on a calibrated gauge but get it in 4th and boot it and it will cut out.

 

Mine peaks at 20 and holds at 15, but then mine's not standard.

 

8 psi is the satndard boost pressure. A weak actuator could be responsable for the 4 psi you were seeing. You are using a good quality boost guage and not a TIM shit thing aren't you??

Unchipped I beleive you can make the car run 10psi after a chip about 15psi. Once you've gone a little silly like me 25psi

 

yep

 

In a nutshell mate.the rs owners club put a figure of 0.63 psi as standard.I converted mine to a chipped ecu and before i put the ecu on i accidently fitted a -31 actuator (bought it off a mate who told me it was a standard actuator).The car flew and when I reached 17 psi the standard ecu shut the motor down.sounded like a double barrel shotgun and i shat meself.Looked in the mirror to see a fog bank which ive been told is unburnt fuel (thank god).I then ran it at 12 psi and it didnt repeat the shut down (thank fook).From that experience I would say you could get 12 psi but i am no expert.

 

will get a -31 actuator then when i get paid then,i had a mk2 escort b4 this which was about 140bhp and when the boost comes in it feels quicker than that,a couple of my mates own 16valve gte astras and it feels quicker than them and they aint standard

 

the boost gauge im using is a pro gauge with the changing colours background,i think its ok 4 what i want

 

cheers krazy kim,hopefully mine will b like that 1 day when ive got the money,got an evo7 intercooler coming 4 it next week so that will help,y cant all women b like u and like cars
