Trashy · Mar 12, 2018

Longhairfreak · Mar 13, 2018

MK4TDI · Mar 13, 2018

Thought Allan was never tracked out? Haha. Looks like a beauty day to be have been sledding

Ballzdeep · Mar 13, 2018

what did you do when you pulled clutch cover off....turn up boost? Wicked vid, nice to see clips longer then a min. :Cool9:

LennyR · Mar 13, 2018

Cool video, looks like it's making some power. just imagine if it was on a real mountain chassis not a bandaided XP, that thing would be awesome eh !! &#55357;&#56841;

haha well thats why its a race sled! its a terrible mountain sled

Lazy backshift.
Something is going on with the clutches.
Losing rpm when wfo for longer pulls.
Fluctuating rpm when wfo.
I would guess worn secondary causing slow backshift combined with tall gearing making the problem worse. What gears are in it now?
Rebuild both clutches, replace the secondary moveable sheave bearing/bushing thingy and start fresh or forever chase your tail clutching.
The engine is running great. No bogs. Nice. Love the vids. I get to tune your sled in bed and naked. So much fun.
Advice is not guaranteed and may be 100% incorrect. Haha

Running very crisp... sounds great!! What was the original turbo kit and who’s controller? If you don’t mind me asking.

kanedog · Mar 13, 2018

Rpms are down 250 rpm so there is at least 10% more with correct rpm. Maybe a 1-1.5grams less could bring some more thrills for you. There's lots more in there!! Get it and kick butt!

maxwell · Mar 14, 2018

yep i was noticing that aswell.

maybe another lb of boost would solve that?

kanedog · Mar 14, 2018

I would pick the boost that I would run the most and tune the primary to that boost number.
In the vid it sounds like the secondary may be worn or dirty cuz of fluctuating rpms and slow backshift. Sometimes that crazy beast will get over 7700 but only when it’s wound out on hardpack. Have a quick disassemble and clean it a bit and check it out for free movement. Post more vids. I can sled vicariously through you that way.

a little Sunday test and tune!
