Hi,,
My 2000 AMK 8L S3 has an uprated K04 from CR Turbo's that was fitted about 18 months ago. The car has only done about 10 miles in that time as I've had it SORN'd and garaged while I've had the use of a company car. I've started using it again last week and the power delivery is not as it used to be.....
The S3 has a custom JabbaSport remap, Forge 007p, Forge Induction, FMIC etc. etc. and was last rolling roaded at 293bhp (at JabbaSport). The problem I have now is that the car only boosts to 0.4 bar until it gets to around 4 / 4.5k revs and then it will start to climb gently until it maxes out at 0.75 bar at around 6k revs. The car used to make considerably more boost than that and would regularly reach 1.5bar +, needless to say it's sluggish and nowherere near as much fun to drive!
I'm pretty confident that turbo is fine, as I say it was fully reconditioned and uprated by CR Turbos a little while back and hasn't been used since. I suspect / hope that it is something that may have come about as a result of the car standing unused for so long? I can't hear any boost leaks when driving though can't rule that out entirely..... Also the turbo was replaced because the previous unit failed so there was quite a bit of oil being burned through the exhaust, not sure if this could have caused issues with something either?
Any thoughts or opinions on likely culprits would be greatly appreciated!!!
Cheers,
Paul
