Did you guys switch to a larger throttle body or are you still running stock?
So 2 or 3 weeks ago with the revised and updated setup we strapped the Rabbit back down to the dyno. Unfortunately we were having some issues with what I believe was the head lifting which was causing pressure in the coolant jackets and also causing the coolant to overflow out of the bottle. Also we were not able to take it over 8k rpms because of a terrible tensioner issue on the main drive belt which causes it to kick the belt off. (IE is working on a fix as we speak) However we were able to put down an impressive 811AWHP on an AWD Superflow dyno pushing 28psi. Attached is a link of one of the dyno runs and as soon as I get the graphs I will post them as well. Enjoy.
This was at a local dyno day. Please ignore the hp numbers that are shown below. He was trying to calculate for a corrected sea level number however it is not accurate.
arent you running an underdrive belt?
I apologize when I answered you earlier I was in a rush. Basically we are just running an ECS lightweight crank pulley but everything else is stock. Problem is that the lower tensioner for the AC/Crank belt gets some bad harmonic vibrations while in the higher RPMs and it is not strong enough to hold the tension down so the belts keep skipping off basically

very impressive gabe.
as for the belt, we had that issue on the road rabbit NA rabbit...we took a mk3 VR6 tensioner pulley the had edges on it. trimmed the mk5 tensioner down a bit and it never came off again. but i'm sure IE can build you one better then stock. thats just what we did quick.

so, with all issues solved, +9 or 10k rpms, we can expect +1000 AWD HP?
also, i wanted to ask: what turbo size a/r etc are you using? when does it start to spool and when does it reaches max/full spool?
already know what i want, just wanted to know what it came with. i assume a large journal bearing t3 or something of the sort. if it comes with a ballbearing, that's awesome.
i already know what i want to use to utilize the engines performance and get the gains for the type of powerband desired based on the comp map vs engine,etc.
though it isn't my car, it will be awesome to have a very stealthy 2.5T running around.
especially on pro-maf tune.

jesu joy of man's desiring... that thing sounds CRUEL.
i'll be happy with something half as nasty and respectably streetable, but is it seriously nice to see (and hear) what these little bastards can do. even happier to see it built from the same molasses 140ish whp '07 foundation i'm on! far above and beyond any 2.slow, and with the reliability of these engines you can score a clean block for the cost of a couple rough nights on the town. i'm dead set on building my gal a terminator heart once she turns 150k, and not one mile more.
