Nice sled looking foward to seeing it come together, but what wrong with the stock front piggybacks shocks???

(unless you took them off cause there was no stickers)

The MTX does not come with piggyback shocks. They come with a standard KYB shock with 1.7 kg springs. I kept the standard shocks but 2.5 kg springs on to help stiffen it up and keeping it from diving.

also what kind of top end will you expect to get out of it with the ulmer turbo???

This sled will not be about top end. It is a mountain sled and will stay setup that way with 20/40 gearing with the 3.0 pitch 2.25" lug track.

Keep the pics coming, looking forward to have a closer look at your turbo kit as the project moves forward.
 
We do not change the compression on our Stage 1 kit. We will be testing a larger turbo with lowered compression for the FX Nytro when we get snow on the ground for Stage 2!
 
sounds good to me...without lowering compression, these turbo installs would be an ease... I'd be interested to see how one of these kits performed agains the others with lowered compression and higher boost levels...Would be faster of the line and through the trees I guess....

Thanks, Bull
 
The installation of the turbo kit is very simple. You have to drill one hole out bigger and drill one new hole to mount the turbo. Then you drill the hole for the charge tube to come through the front. Otherwise no other modifications are needed.

A few more pics of cutting the running boards pretty much completely off and then reattaching the Better Boards and also cutting, heating, and bending the outside running board grip to match the new running boards!
