hi all ive had my car set up and its running poor power,quick spec
stage 1 head
piper cam
vernier pulley
bayjoo chip
-31 actuator
front mount
mf2 5th injector
k&n
exhaust
standard t3
when it fisrt wen on it was 240 bhp @17psi but really lean,when he sorted the fueling out the power just kept coming down,the boost just drops straight off wont hold,it finished off at 170 bhp @17psi,
any answers would be much appreciate as its doing my head in.

 

what you using for boost control?
sounds similar to mine with a bleed valve fitted- needs proper boost control imo.

 

ive no boost control,its on a bleed valve.

 

170 sounds about right with the spec,though am baffled why u have a 5th injector at that level of tune,240 is never gonna happen with 17psi on a std t3

 

First run probably had wheelspin. There is no way it'd do 240bhp with that spec.

 

what sort of power should i be looking at,since all the work has been done the car does not feel over responsive on boost,the tuner says the turbo seems lazy when spooling,and why is the boost dropping straight off.

 

the 5th injector was to help with the fueling

 

Yeah as above 170-190bhp on a stock T3 is normal, the boost is dropping off presumably as the revs increase yes?
This is beacause as the RPM goes up the amount of air flow needed from your T3 to hold any given boost pressure increases, and as it is a stock T3 on an engine with a ported, cam'd head, it cant do 17psi.
What is it holding, 11/12psi?

A upgraded T3 is your answer

 

cheers karlos,yes its holding that kind of psi,what upgrade of turbo am i best looking at.

 

Yeah thats what I expected...
Stage 2 or 3 T3 is what you want mate, just be aware that the Stage 3 will be laggy on a little 1.6 making peek boost around 3700-4000rpm, so really depends on what you use your car for, IMO stage 2 is perfect for daily driving.

 

full boost is more like 3000-3500rpm

 

JamoRST Is that on MFI??

 

all i want to do is maximise what ive got for now,and as its on mfi ill be looking to change everything in a couple of years.

 

where the best place to look for a stage 2

 

Yes

 

Turbo Tecnics or CR Turbo's, just google them mate.
Thats impressive, the two engines i've had Stage 3 T3's on never made full boost that early, but then they were running a Kent CVH 35 and a Piper 285T2 which didnt help!

 

My ex _standard_ t03 made 15 psi of boost at 2800rpm no problemo and it held it until limiter. But i recommend turbo & managment upgrade too.

 

I recommend vince @ http://www.crturbos.co.uk/ I get all of mine from their, best service ever, tell them your spec and what you are after and they will built it to suit

 

what wheels are they in your signature?

 

Matt35,

Also try http://www.shepherdmotors.co.uk/services.html as they are really helpful and tell you like it is.. Also they have built some nice motors with differing stages of turbos so know what they are talking about and the best thing of all they are quite reasonable not cheap but cheap enough.

that was with my newman cam

heres the graph before i got my newman with a piper 285 t2
