So we're comparing apples to oranges then, always a good start.
I've seen the way you debate on Pistonheads and it does come over as derogatory I'm afraid. And I know more about this subject than you appear to give me credit for.
Good for you, you spend your money how you see fit. I wouldn't spend my money on a carcinogenic smoke belching Derv Scirocco personally, but each to our own eh?
You are a firm believer in provable gains eh? You had nothing 'provable' to contribute in the Revo 400hp Octavia thread when a very clued up guy said it was BS, if I recall. You more or less surmised if it feels quicker, then it is, which is what we all think, no? So what's your problem with my intercooler findings then? I bolted it on, car feels better, so what? I'm not into this whole Pistonheads style of having to justify myself and provide scientific evidence to back up my claims. Pistonheads is for tit for tat, this forum is somewhat above that as we're enthusiasts, not nerds.
I don't really care what you think about diesels - or what you know (or don't know) about intercoolers or tuning cars since I don't know your experience level (nor have I questioned it. I questioned your claimed results)
The fact is that, in itself, an intercooler does not provide you with power per se. It allows you to maintain your power in hot conditions and multiple full power runs, and, at higher levels of tune, not be held back by restrictive cores or poor cooling creating high inlet temps which causes you to lose power.
Charge air is charge air and it doesn't matter whether it's petrol, diesel or piss that it's running on.
I
have done before and after runs when fitting an upgraded intercooler (going from the stock TDI intercooler, same as a normal GTI one, to in my case a THS) and it
proved to be no different, except at the top end where it held power slightly better but didn't actually improve peak power and certainly not enough to feel it (you are not going to feel 5 or 10bhp on the road).
As I have said in the past, if you are happy with it then great - but I think it's misleading to other people who may be reading the thread to believe that if they spend £250+ on an intercooler their car will feel quicker where as I do not believe that it does on a stock or even Stage 1 car without repeated high speed runs with limited recovery time.
I didn't need to prove anything in the Pistonheads topic you mention (which is completely unrelated to this one I might add!!!)
A few (3 or 4) members seem to troll highly tuned "normal" car threads, saying they are all BS - without any evidence or proof to back up their argument (that the car wasn't doing 400bhp). Then you have the people (I presume like you) who see lots of big words talking about cylinder peak pressures and side with them rather than the actual measured output.
If a bolt on map with no other modifications, can achieve 370bhp I'm very confident adding intake, exhaust and intercooler will contribute to a 400bhp peak figure.
Revo had dyno proof of their power, as well as acceleration times which were around the same as other cars of similar claimed power.
But as I said this is completely unrelated to this intercooler discussion. I was not rude or derogatory to you at all in this post.
I post in different styles on different forums. So I don't really think it's your business how or what I post on other forums, whether they are PH, Mumsnet or Pornhub.
