I think I may end up ditching the poly mount if it could be causing this.

Thanks all.

they sound good and gives you more road feedback its an "R" so i think it blends in to the rest of the set-up

Ok it seems I should keep it then.

I just been out and realised its got a re-circ blanking plate but no dump valve? What in gods name!!!

I have another problem now too, the car pulls fine and runs well until.... you boot it the boost guage moves and it appears to boost but the car shudders almost like the wheels are madly unbalanced or the anti-lock brakes are kicking in. Its neither obviously but annoying. Going to try standard ecu see what happens and if not must be a boost leak.

What do you chaps think?

It could be wheelspinning, mine feels like that.................................. last time I drove her!

Its definately not wheelspin mate.

Its a shudder felt alot through the wheel. Going out to have a tinker ill report back shortly

hazium>>>Am liking that. Did ya cuz get his T5 sold?

no mate dont think so havent spoke to him in a week or so but id imagine he,d be on the blower to tell me she has sold,cant for the life of me understand it,the 850s/s70s arent as big a secne here as there but ,the first person to drive it will buy it,i spent at least three times its asking price on it!!!

I've got to do the gearbox mounts next, just need a gearbox in the car to fit them too!

does tend to help a bit lol. I have only done the larger mount at the minute but got the bush ready for the smaller one

Mines got a recirc blanking plate with no dump valve and has had for about 2 years now. I recently fitted a new turbo and the old one when removed had no play to speak of in the shaft and no oil consumption or smoking issues so not a major issue with the boost these run on standard or mildly modded states.

What do you chaps think?

The boost gauge is showing boost increasing ok though?

Obviously my hands arent on the steering wheel you you sure it isn't feedback from the blast of torque to the wheels?

Yes showing increasing boost.

Just swapped ECU's for a standard one took it out and did the same.

Its definately not torque steer either. Best way to say I suppose is it just isnt running right lol.

I think new spark plugs and double check all boost pipes but they all seem intact and in good condition.

Glad to hear I'm not going mad - or that there are two of us who are LOL!!

3 now!!...exactly the same on my p2

On the vibration issue, now mine has the main silencer off, you can feel a slight vibration at idle. So if you've got a sports exhaust with a poly engine mount, perhaps together they are the cause.

Yeah Im hoping thats the case I have tried everything else now nearly!

Just need to sort this boost shudder. Car drives perfect just except when you put your "pedal to the metal" so to speak.

Not getting enough fuel at full throttle?

Possibly, I have put the white injectors into it, you may well be right though. Worst case new fuel pump I suppose. Ironically there is a spare fuel pump relay in the box of bits he included... wonder if this has something to do with it?

**t5 pete** · Sunday 21st November 2010, 21:14

most likley the plugs

Does it take the ecu a while to "learn" the bigger injectors?

**t5 pete** · Sunday 21st November 2010, 21:16

also i personally wouldnt have put the injectors in as it will be mapped for orange injectors wait untill you get a map for the injectors as at the mo they will not be benifiting you just dumpin extra fuel in

I would have thought as the Rica is a generic map it wouldnt have made that much difference just reduced the load slightly.

Im hoping it is the plugs but I inspected them and there werent excessively fouled. Its clearly an air/fuel problem though... or rather it has to be!
