You guys said you're running "custom cams"? What is the duration and where did you source them from?
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
Makes me want to sell my GTI and build my 2.5L Golf.
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?
I think if you ask anyone they would think it was impressive....
well except for all the GTI and GLI guys on the MKV forum haha. I still think its funny that a bunch of them have no restect for a motor that can make this kind of Hp.
I wonder what kind of numbers it would put down as 2wd only, without the crazy loss from the haldex.
