After doing some clutch testing yesterday I had a lot of oil in the skid plate and all over the engine / transmission, got it all degreased today and removed the clutches and enclosure and found the leak, all 9 of the bolts on the drive pulley shaft cover were loose, not just a little loose but...
Did some testing with the KWI Clutching setup today and it’s gonna be good news for the rock crawlers!!
Nice smooth low engagement at around 1500 rpm, it can crawl a 25% grade at 1-2 mph.
15% reduction and was still able to hit 96 mph before hitting the limiter!!
But…. We think we can make it...
Yes, the belt we are now testing is way longer and wider than the GBoost, the KWI secondary is larger in diameter than the OEM secondary so it will allow for a longer belt and therefore more low end reduction
We have it all set up and ready to rip, been playing with different belts and springs to get the lowest engagement and most reduction (we are trying to set up the clutching best for crawling as it's already been tested at high speed in the desert) we are currently at over 15% reduction on the...
You would need to measure the spring, Inside and outside diameter, length, and wire diameter and I can calculate the rate and see if we have anything that would work.
With a center bearing primary the secondary spring should control the belt tension and should really have no or very little deflection, if the secondary reaches full shift
(all the way closed) and doesn't take up all the slack in the belt then it will get loose.
We modify the secondary...
I'll have some other components tomorrow to set them up, these clutches have been tested for several weeks in fast desert conditions so I'm working on the other end of the spectrum, slow crawling, I'm working with KWI and setting it up to see just how low of a belt engagement we can get and will...

I would have thought so as well but 01680 is the highest VIN number I have heard of, if there were way more than 2000 out there you would think someone on all the Facebook groups would have responded as I posted that question on all the H2 related groups.
Going by the VIN, the highest number I have seen is 1680 on a dealer lot and the highest number anyone has responded to me with on all the FB groups was around 1300 so it appears there are less than 2000 total units out there which shouldn't take long to retrofit once the fix is available, I...
We do quite a bit of machine work to allow the secondary to close more and allow for the use of a longer belt which then allows the belt to ride higher in the secondary giving you lower initial gearing,, the secondary should not be fully closed with any belt as it then becomes loose and the...
