Hi Everyone.
I have a 2002 mk4 Golf 20v turbo ARZ engine 97k...I think it has a k03s
Since yesterday Ive noticed the car seems to be holding back when I accelerate hard ( between 2500 to 5500 revs ) as if its not boosting properly.
The car still goes quite well but there seems to be something missing. When i rev the car out of gear, I can here the turbo spool up but on a run it holds back. The wife thinks its the hot weather........
Any suggestions on what it can be?
Starting to p*ss me off now!!! :angry:
Thanks everyone.

The hot wether does considerably effect performance on standard 1.8t's as the side mounted intercoolers are not very efficient so the charged air temp can remain quite high as it enters the engine.

Sorry Mate.
Should have said....The car is fitted with a front mount from the last owner, but the car has the standard GTI front bumper. So I don't really think there's much air getting to it anyway.

Yeah could be, when I had my Leon Cupra 1.8t i'd estimate there was around a 30bhp variation between hot and cold weather. All forced induction engines suffer with it, some more than others.

I thought for a second that there might have been a bigger problem.....Well a remap help this issue in hot weather?
Or im I going to get the same holding back issue .....
-
ARZ has a ko3 as standard :wink:
-
if its holding back check the MAF/ whatever induction you have
-
you need it hooked up to record logs and fault codes, second guessing everything won't help
