does the air temp senser mount back in the intercooler and what other lines that went in to air box go into intercooler Thanks Tim

Ya theres a hole in the side of the intercooler for the sensor and two small holes pre-drilled for screws..
No other lines go too intercooler from airbox.. You have a vent off the top of your oil reservoir that went to airbox that now just goes to atmosphere or some guys are installing alittle collection bottle for oil.. Theres also the vent line off your valve cover that now just goes too atmoshere..

Out of curiosity, did the sled run with a high or low idle when the hose came off?

Sled Started/Idled fine.. I was on the hill and my AFR was all over the place mostly in the 14's. I kept turning up my fuel regulator pressure to the point it would hardly idle and finally saw mid 13's on the AFR, still too lean but I was taking it easy... Don't ask me why but later in the day I decided to try turn up the boost, stupid I know espically as lean as it was. I tried everything maxed out the boost controller, adjusted the wastegate nothing couldn't get over 11psi. Rode back to the truck and while it was idling on the trailer it sounded different, sounded like an air leak.. Sure enough I found the hose off between the idle air control valve and the intercooler. Won't make that mistake again!!! I talked with Dave afterwards he said boost leaks can be identified by the following:
-Crazy AFR numbers that are all over, and sometimes indicate a lean condition
-The sled will run flat on the top end
-sled will loose rpm and not pull its clutching
This confused me, I thought that if a motor was rated at 100hp @ 10psi boost it would always make 100hp even with boost leaks assuming the turbo could keep up to the extra load of the leak. Not so apparently, Dave spoke of compressor and intercooler efficiencies that can make big changes to a motors hp output at any given boost level. At least thats how I understood it!!! I still don't understand how this can affect the AFR reading as I seen. As you can tell I'm very new to 4 strokes and especially to turbos, by no means am I an expert, or even a beginner. If I am incorrect in my above statements please correct me, no sense passing along non-sense garbage!!! Sean
