I think Mighty Car Mods did a myth busting thing on black intercoolers. I can't remember the outcome though
Is a welly cooler like a little fridge for Wellington boots or something?
I think some folk get a bit too wrapped up in "For stage 2+ - You must have a 3" catback, you must have a massive intercooler, you must have grade 7 spark plugs, you must have Millers Nanodrive.....". You don't NEED any of it, technically speaking. But a bigger IC certainly helps keep heatsoak down, but the more volume the turbo has to fill, the more chance of lag etc.
I think the Might Mods test made minimum to no difference. The only reason id stray it is if I wanted it to be a sleeper etc
Welly was the name of the first guy to try it universal intercooler on audi sport forums, about 5 years ago now. just a bit of banter that stuck.
Yes I totally agree. people going with all these name brand parts make the price of stage 2 ridiculous.
When I fitted my welly cooler I definitely noticed more torque, but I also noticed there was a bit of lag too. but once the intercooler had filled up its pulled hard and nicely. You dont really.
Even those cheap Ebay twintercoolers do the job for stage 2.
In other words dont break the bank lol
Ah right, so Welly cooler just means 'generic ebay cooler' ? Never knew that, good info
I like things to be simple and I'm not into chopping bumper irons and stuff either, so I just dropped an S3 intercooler in instead. The post 2010 one with plastic end tanks, which was about £230 from Audi when I got it. Cheap for OEM! The all alloy one (with minimal gains, hence why Audi dropped it) is now about £450! I haven't noticed any lag, but then it's not much bigger than the GTI one!
I also tried a turbo muffler delete and a bigger turbo discharge pipe (KO4), but those two made bugger all difference, so took them off!
I think there comes a point where some mods make zero to hardly any difference, but folk still fit them anyway because the internet says so
