well... I did my own kit because their are some things I wanted that no one else offered and I just wanted to do it myself. I have lots of experiance with turbo street bikes, but this is my first turboed sled and a carbed one at that. I wasn't sure if I wanted to turbo my xp because of the carbs. but after reading the carbed 2 stroke thread a hundred times, watching a few turbo xp videos, every picture I could find of a turbo rev and xp, and posts by gus and info from dave at r&d turbo werks I decided to go for it. Thank you to dave at r&d for some help on the phone and the parts. If I was to buy a kit right now it would be a R&D turbo kit. Mike at cpi was also great on the phone with some advice and got a turbo pipe out to me right away.
I used a garrett 2871 with the tial stainless turbine houseing (turbo weighs 10lbs, 2 oz), tial mvs external wastegate, tial Q bov, cpi turbo pipe, boyesen turbo reeds, dynomo joe qr11 helix, 20.7 grams on clicker 3, and dynomo joe mountain ramps.
Holly ****... The thing rips. I was doing every thing I posibly could to get good throttle responce. I had a slp pipe, and head last year. Several others have got the same setup after riding mine and love it. much better throttle responce and mid range power then a stock xp. My TURBO xp has as good as throttle reponce as the xp with slp pipe and head with a **** load more top end power. It just keeps on pulling and never stops. This is only on 7psi and pump gas. I only have 3 days on it, but it has ran better then I expected. It runs great from 5,500' to about 7,000'. Once I get around 7,000' and above it looses the midrange power a little and throttle responce drops off. Still pulls like crazy on the top. On the first day it sputterd and loaded up bad at 8,500' on the bottom end. Second day I started going backwards, but had it runing better by the end of the day. On the 3rd day (today) I got it to where it was not sputtering, but wasn't nearly as good mid range and throttle responce as 6,500' and below. So I will be doing some more tuning and trying some things with the carbs to hopefully get the throttle responce and midrange to work above 7,000' as good as it does at 5,500-6,500'.
Overal I am pretty happy that it has ran as good as it has with relativly very little tuning. just turning the power jets a little and playing with the fuel pressure. Right now I just have the power jets set for above 7,000' and stoped when we hit the trail on the way home to turn the power jets out for lower elevation down the trail and across the lake.
Sure is fun making climbs and the front skiis never touch the snow the whole way up and you have to let out so it does not go over backwards. This is with a 154. Can't wait to turn it up to 10lbs of boost.
I am just happy that the sled has ran so well from the get go with no real issues except some tuning.
Sorry I do not have any pics. The second I got it done I loaded up and headed to the cabin to ride. I didn't bring the camera. I will take pics when I get back into town on sunday or monday. Sorry no video either since I don't own a video camera. I will have to see about barrowing some ones.
