S60R boost issue

6 posts in this topic

Soooo the car in question is Chris's old S60r 2.4 with an Owens development 19t turbo.

 

 My issue is I'm only getting 0.5 bar of boost instead of 1.4 bar. I can drive the car up the street with it boosting fine then all of a sudden it disappears. I can turn the car off and on again and it magically appears then can disappear at any time.

 

I've been advised that it could of been the tcv, I've since changed that with no resolve to the issue. I've recently put a snabb cold air intake pipe on and noticed the maf is quite oily, could that be the issue? No codes via a generic code reader and nothing on the dash. Any ideas and advice would be greatly appreciated, thanks.

I'm assuming the R's have a map sensor mounted on the intercooler pipe like on T5's,if so,I would try changing this as it caused the same kind of boost issue for me

Are you sure the mar-turbo pipe is fitted correctly on the compressor housing?  You can clean the MAF safely with electrical contact cleaner as it leave no residue.

Would be worth checking all vac pipes and that the TCV is plumed in the correct way if you haven't already.

Has it thrown any fault codes? Failing that plug it in to VIDA

Thanks for the replies gents. I've checked all the pipes, it was doing this before I changed them over.

I've cleaned the maf this afternoon and I'm about to put it back in at some point this evening. I'll test drive the car tomorrow and pray that it's sorted. Failing that, it will be going to a professional next week.

 

I'll update as soon as it's resolved.

cheers.
