found it, this was a MKII Leon Cupra
As a guideline, on mine, with stock code and no other mods, we saw inlet temps decrease from 30oC to 17oC with outside ambient temp of 13.5oC.
On a mapped car, we saw 20-25% drop in inlet temp with the S3 intercooler.
Thanks for the info manor13. My main worry is the boost pressure difference between a 2.0 TFSI and a 2.0 TDI. When people start running 25+ PSI on their TFSI Is the S3 cooler still up to the job?
As you can see from my pics above there is a fair bit of oil in the boost hoses which will be sapping my power. Also the boost hoses are really soft so it all needs replacing. I'm sure with a clean FMIC and a catch can ill get most of my performance back.
Can anyone tell me if the 50mm Allan key bolts pictured above from the EGR delete are a standard Audi bolt?
1 has dropped out which may explain some of my poor performance.
aso just looked around was that intercooler run as a twintwecooler? aka aswell as the original like they advertise for the s3 and tfsi ?
I'd love to have a big cooler just behind the bumper by itself as that'll offer the best performance and cooling but If an S3 cooler upgrade keeps the temps down on a hybrid It definitely looks the easiest option, if a little expensive.
