10k Revs of 2.5L Big Turbo AWD Rabbit Madness!

[gabe@bwperformance]

Just wanted to cross post this from another thread in regards to our dyno numbers.

i'll say it again and again...it's a way different motor...way too different.

also. what is your plans to get 1000? BW just built a killer setup with E85 and only(only haha, its a lot) 615 fWHP. where are you finding the other 400whp?
not knocking you...just interested as to what you plan?

Just an FYI the 619FWHP was put down only at 20psi and only pushing to around 7500 RPM. The reason being is that the night before we had sheared the ARP flywheel bolts at the strip and decided to put some generic grade 5 bolts (all that was available) back in along with welding the flywheel to the crank. So needless to say we were taking it easy. Since the event we have redone the motor and have done many pulls past 9k rpm and have boosted it over 35psi. Trust me its faster. We hope to dyno soon AWD but I promise 1000AWHP is possible with this motor. (Our current setup, I am guessing can produce around 850awhp.

bw and hep did an awesome job... congrats

That's amazing, can't wait for complete results.

Throwing one of these on the Rabbit tomorrow.

[DarkSideGTI]

Co-Branding win.

[pete@blackforest]

Awesome!

[pennsydubbin]

any pics yet?

[gabe@bwperformance]

not yet.

[twoteks]

When do you guys start making boost with that mammoth turbo?

[gabe@bwperformance]

boost comes in around 4,000rpm.

[twoteks]

You guys said you're running "custom cams"? What is the duration and where did you source them from?

[gabe@bwperformance]

The cams never came around although we are hoping to finally have some here real soon.

[DerekH]

Did you guys switch to a larger throttle body or are you still running stock?

[gabe@bwperformance]

Still running a stock TB.

agreed!

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.

[thygreyt]

arent you running an underdrive belt?

[gabe@bwperformance]

arent you running an underdrive belt?

yes.

[mldouthi]

This is awesome Big

[thygreyt]

yes.

why is it shearing off then?

i thought that the underdrives were "fixing" the issue...

because on the stock pulley/belt the issue is pretty bad

[gabe@bwperformance]

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

[DerekH]

Pure awesome, how are you going to fix the head lifting? I thought you already had arp studs in there.

I'm assuming that the belt fix is going to be a stronger tensioner?

Edit: also, where is your valve cover?

[Aonarch]

Drool.

Makes me want to sell my GTI and build my 2.5L Golf.

[GTACanuck]

Beastmode = ON

That is freakin amazing, great job!

[nothing-leaves-stock]

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.

[thygreyt]

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 remember reading on here or on fb that it starts to boost at 4000rpm. They also mentioned the turbo size, but I forget that.

lol hadnt even noticed! i dont post to build the count thou... lol.

found it on post 1...

Precision 6765 Billet turbine Ball Bearing Turbo.

if you ask me, its pretty dayum impressive!!

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.

Those guys are more concerned with "low", led lights, and "high performance air intakes" than anything else

[thygreyt]

its funny... the 2.5L tech forums is a LOT more tech and in deph involved than the 2.0T FSI, TSI and the "TSI & FSI" tech forums.

and most of us are MOSTLY not really involved with the mkv forums.

Idk the mk6 guys might have em beat being concerned with LED tails
