I have only just got my cossie but i'm assuming it's stage 3. It has got Rolling road print outs of 309 bhp and 299lbs/ft of torque. Green injectors etc etc..

Anyway - it has got a t34 turbo boosting to around 12psi. Is this the maximum boost I can safely run or can it be turned up a tad without messing things up?

 

HI MATE IM RUNNING 1=17PSI 2=22PSI 3=32PSI MATE YOU CAN TURN YOUR T34 UP BY DOUBLE

 

ok...maybe i'll do it bit by bit. How do I do it though?

 

Thats low boost for a t34 runnng greens really. Although for 12 psi 309 bhp is very good. Most stage 3 cossies run 25ish psi. Also are your green injectors 803's (dark green) or light greens.

Dont turn the boost up willy nilly without getting the fuelling checked by a pro. there may well be a reason your boost is only 12 psi

 

they are dark green sorry. So how do I up the boost?

Previous owned said it just needs a set up or down to a boost valve fitted.

 

update: It's going in for a full set up on saturday. Better to be safe than sorry as Ma used to say

 

To up the boost you shorten the actuator rod. This puts more preload on the spring and hence more boost is needed to open the wastegate penny in the turbo. But dont do it. Let who ever is setting it up do it so they can monitor afr and check for det.

 

Im peaking at 32psi, holding 28psi on mine turn that boost up

 

mine has 803s, 3 bar, t34, rs500 inter etc.

my lad has turned mine down to about 10psi whilst i ran it in!

reckons he wont turn it up, obv scared at how much am gona knack his stage 1 escort! so i have booked in for a set up now its ran in and get them to set my boost!


then he keeping off it!

 

10psi

 

I had the car set up by Tremona Garage in Southampton on saturday.

Now its running about 25psi. Daaaaaamn its fast! Flames out the exhaust the lot! Turns out the diaphram on the dump valve wasn't sitting correctly and the pressure was being lost.

Can't recommend Tremona enough - check 'em out!

 

Bet that feels much better flames are wicked aswell

 

where in southampton ar tremona mate ?

i might take mine there when i'm across next

They know their stuff. Set ups are carried out on the road - just don't tell plod

If you go there, ask to see their show cars - impressive stuff! There's an Escort Cossie in a carcoon with only 1600 miles on the clock from new!
