Hello,
Has anyone put a turbo blanket or beenie onto there GTI (Either K03 or K04)?
If so was it a generic blanket cut down to size or a specific K03/K04 product? Where was it purchased.
Also what are people's thoughts on doing this....
...(aiming to lower the heat being transfered into the intake and also help spool time)
Cheers..
I think you're misunderstanding what a turbo blanket is actually for... you should be looking at more efficient intercoolers instead.
....The Audi S3 intercooler drops into the Mk5 GTI very easily,
Whilst the S3 i/c may be a straight swap, the job certainly aint "easy"!

The stock oem intercooler on the Mk5 GTI/Ed30 is actually well thought of by independent experts - Far more efficient than on the Mk4 apparently and not really needing replacing unless you're in Florida or Arizona or do lots of trackdays - You in the hot part of Oz? You're not getting heatsoak are you? - If not, don't bother. Get an air intake instead, or a Milltek exhaust.
Sorry, but can't agree. Even in chilly old Blighty, you can get heat soak in the standard intercooler, and you don't need to be doing track days either.
The uprated S3 i/c is around 40% more efficient than the standard GTI one, and even a totally standard GTI can benefit from the S3 i/c.
Also Forge offer a Twincooler which adds onto the front (and partially blocks the radiator!) as an addition rather than a replacement.
Huh - that's nonsence. The Forge Twintercooler no more blocks the coolant rad than does the existing air con condensor, AND the standard intercooler, which are both mounted immediately in front of the rad!

I know that Forge originally gave up on this product because they couldn't improve the stock.
I think that might not be true! The Forge Twintercooler is very highly rated, with actual vag-com logs to prove its effectiveness.
