as title was out in the cosworth and wen giving it some its is limiting at 4-4.5 rpm it just burrbles and pops like its hitting the rev limiter early it sounds like it could be a back fire but im not sure (rough spec is chip,stg 3, rs500 i/c,d/v,ram air filter, i only got car yesterday so im gettin th spec confirmed by garage) i have power readouts for 348bhp, anywaywould could the problem be im worried now my mate was behind me and said he is sure he saw some black smoe come out of th exhaust when it was limiting,

i tried reving it to 6k stand still and it did and wen i was in second i took it to 6k whilst movin but i donr it gradually so it was prob offf boost I NEED HELP LOL!!

 

Check your plug gaps would be the first point of call

 

ok ill look at my spark plugs wat should the gap be

 

Plug gaps and plug leads, both have been problems on cars I've had :/

 

ok guys thanks im worried it is serious thou argghh lol

 

How much boost is it running ?
It might be overboosting and cutting out.

Steve.

 

I wouldn't panic mate, cut-outs on heavy boost have happened on about 70% of the turbo cars I've had at once time or another. Was never anything serious, just annoying.

 

im sure he said it was runnin 26psi but i sure wen i drove it tonight it was hittin 30psi how can it change though as wen he took me out in it it was fine and on way home seemed fine but tonight not so good

 

It can peak at 30, hold 26?

 

no im pretty sure it was peak at 26 hold 24psi come to tjink off it

 

Christ knows mate I know nothing!

 

no nor do i mate lol ill get to a garage tomoz an just take it easy

 

Get it set up

 

Yep get it setup!

If you post up what plugs are in it though someone will be able to tell you what gap to run for that plug!

26psi is right on the limit for greens mate

 

Is it an Escort?

 

no stu it a 2wd saph ill look wat plugs are in it its booked in for full service and set-up an rolling road not till the 6th of june though

 

any more ideas people

 

same problem was the leads
6 june ant far i know it is hard to wait but a lot longer for a rebuild!!!!!

 

yeh im waiting just drivin it nice an easy so it hopefully will be fine

 

I have had similar probs in mine mate, set up needs to be right, first chip i installed was no good, now have Bayjoo chip+pectel board, problems again this time it was the loom plugs that run along the bulk head at back of engine/rocker cover, cut them out and joined wires together lasted about 18 months same probs again now, car may need re-looming, cossies lovely when their working properly and a pain in the ass when their not my car runs around 25-23 psi on the boost peaks at 25 holds 23

If it was me m8 i'd bung in some 071 plugs gapped at 0.6 mm,new dizzy cap and rotor arm.

 

i had the exact same symptoms with my rs turbo engine, would rev fine and then sound like it cut to 2 cylinders.

as people have said it was the plugs, was blowing the spark out. when i took them out they were set at 0.7mm, i reset them at 0.6mm and its perfect now. different engines but sounds exactly the same.

 

yeh it will be getting all that ksa when it has it full overhaul and major service all plugs, leads,dizzy,oil,fuel filter and pump etc etc

ksa im sure i know u from rsmania when u had ur awesome rst u were good mates with t28 i think

 

Thats me m8,sorry i've forgotten your name

When i bought my saph i did the cambelt and tensioner too.

 

yeh i have booked it in for the cam belt alt belt and all the usual on 6th june

ksa my name is jamie im th one who is from england but half scottish and support celtic lol

 

Hiya Jamie cant believe you still support that shite team

Nice saph by the way.
