Just about ready to go! A few little things left to do, but nothing too major.
Currently the sled is setup 100% stock (clutching, exhaust, intake).
I do have the following installed for data aquisition, etc.
I plan to play with some new air box modifications as well as a few different exhaust setups as well.

Rear skid is a modified stock skid with 4 additional wheel kits and 2 stock wheels as well. Also has Tri-Hub eliminator kit installed as well for the rear wheels.

How did you have to modify the skid to run the 10.5 track? I was thinking of doing this as well for the summer. Did you have to narrow the rails or just put a bunch of wheels on it?

The 10.5" track uses the same rail centers as a 15" wide track. I used a different rear skid arm that has the upper idler wheels moved in, otherwise it's a stock skid assembly (with more wheels added into it).

So, which speed wire gets tapped into to get speed signal for the PCV to monitor??

What was the rear arm out of? I'm assuming you're running shorter shocks in the skid?The 10.5" track uses the same rail centers as a 15" wide track. I used a different rear skid arm that has the upper idler wheels moved in, otherwise it's a stock skid assembly (with more wheels added into it).

There's more to it than just hooking up a wire, you have to calibrate the sensor in the PCV as well. Call me and I will walk you through it.

I used the rear arm out of a F7 rear suspension, you need to cut a few things off and only use the upper part of the rear scissors/arm, a few spacers and bolts to make it work as well, but nothing too major. I have the front arm sucked down with the limiter strap (had to drill new holes) but it is the stock shock, no rear shock, the rear arm is mounted solid. Give me a call if you're serious, I can set you up with everything you need to get on the asphalt.
