My sapphire is making 18PSI peak and then drops to 15PSI. Is this too much?

Is stage 1 with standard injectors. I know that 15 PSI is max recomendend for stage 1 but don't know if it's peak or constant boost here.

thanks in advance for any advice

 

thats wot mine peaks at 2 mate mines a stage one and its been running fine like it

 

same with mine too. stg 1 and all that, peaks at 18, drops to 16 and holds that. so no prob there mate.

 

just out of curiosity wot chips do u 2 have????? mines a pathetic superchip thats being changed asap

 

Just make sure the fuelling is ok .

 

Chip is a Collins.

I'm asking this because I have started to feel a strong vibration past 4000rpm, don't know if it has anything to do with turbo. l didn't notice before with 13 psi. something like having a engine mount broken or so (but checked mine and are fine).

 

Is it just revs or more like a fixed road speed? If its just revs, check your exhaust for fitment, ie sometimes if its not hung correctly and some part of it is stressed then it can cause a vibration/tizz also check your turbo damper...an item that gets over looked, mine included

Stu.

 

Had a look and something is wrong with turbo dumper. going to take a picture and post it here in some minutes

 

Spring is compressed a lot and there is a big gap also. Don't know if this is correct.

 

well, the vibration has to do with the gearbox for certain. now it's getting harder to shift... any ideia?

 

turbo damper looks quite normal, but hard to say from those pictures. i have the section of workshop manual that tells you how to adjust it correctly if you would like it?

 

Had alot of vibrations throuh the gear stick at 2500-4000 rpm but got my self a bailey turbo damper. it feel like im chaning gear with the engine off now in comparson to how it was getting before.

Defontaly a worth while mod in my opinion and looks the business

 

Thanks, I have the workshop manual, they say 4mm between supporter and damper, but I have a lot more, spring doesn't look too good.

I think I will get a new damper kit. Anyway I have ordered new engine mounts also. I'm getting crazy with this.

 

Mine starts vibrating like hell around 3000 (as soon as I get positive pressure) and never ends till I decelerate. If I acelerate gradually without puting too much pressure, vibrates but not much.

I believe it has something to do with damper or engine mounts.

 

isso parece-me detonação (mistura pobre dá combustão anormal)...
nao sera isso?

boa sorte!!!

 

as paconassa said: probably detonation

checked sparkplugs and are all f**ked with no poles at all

already ordered new 071's, was using 901s

I was able to buy a new turbo damper kit (original one and the last in Portugal ) (99 Euros + vat) ouch!

 

new plugs, still the same... I think I will need to remove the gearbox now, have nothing more to be done except for the new engine mounts....

 

Got the gearbox out today, replaced clutch kit with a used one just to test. Every vibration went off. evrything is fine now, however clutch is used and engine slips a lot.

anyone has a cheap one for me?
