6psi drop would be a leak IMO. The cooler looks a decent size don't see why it would be the issue. I personally run a $100 600x300x76 eBay cooler and have had back to back 450rwkw dyno pulls with a maxed out turbo, intake temps are fairly high around 70* but it was also 40* ambient temps. A leak will also create high intake temps as well so I'd go looking there before changing the cooler. Nice job with the diy tuning btw always good to see other people have a go and learn something.

The cooler has been custom mounted, just measured up the core (excluding end tanks, measured to the welds) 3.5inch (90mm) thick, 500mm wide x 400mm high.

Tried for some pics of where it sits but bad light today, wish it was silver for photos

Yep that's a rapid V2

U owe me a happy meal bitch hahahaha

Haha that's fair, how do you want to get it?

I did a little google work today and from what I saw the v2 should be better than 320rwkw, but didn't see a heap of guys data to compare, not sure what to think.

Ahh not sure what happened with the video sorry. Video explained more but basically epic boost leak in one of the cooler pipes, it's been pierced.

.... can I get a happy meal aswell? haha.

just saved yourself 2k with a simple test.

Haha I suppose $2k buys a lot of happy meals :P

Yeah was pretty happy when we found it, brief forum post in the heat of the moment probably didn't explain it properly - more money for other goodies now though.
