Nice video you guys really have the sleds set-up. I'm thinking of doing the the undertunnel exhaust this summer. I just watched all three of your videos on youtube. There is alot more snow this year than the past couple.
 
Missed your videos this year - keep them coming!

I would really like to some pics of the "kachess pitot-system" on that bender turbo sled!

Show us some pics of your updated pitot system. I have a MPI/Bender stage 2 so I'm very interested.
 
The pitot valve is nothing special. I bought an ice maker valve kit which came with a little needle valve that clamps onto a 1/2 in copper pipe and a coil of small copper tube. I cut off a couple of inches of the copper tube, attached it to the valve with the compession fitting. I removed the pitot jet, put a groove around the nipple that the pitot jet screwed into so a rubber hose would not blow off when clamped with a hose clamp. I clmped a rubber hose (1/4in i.d. ?) to the pitot jet nipple then ran it up to the ice maker valve which I attached to the frame above the brake. We run it closed on the trail, and then crack the hood and turn it open when we start climbing. Usually 1/2 turn to 1 1/4 turn will achieve the right mixture at elevation. The valve has a little rod for a handle so it's easy to count turns.I found that if you are too eager you can lean it out too much real quick. We've run it reliably from 2k to 8k feet with no problem. Not rocket science, but I can't imagine having a pocket of jets and swapping them out on the trail.
