I rode Revelstoke again today, 4th trip on the s/c and it ran flawlessly. I am pulling 1 lb off idle, 3 lbs at midrange 4000-7000 and 5-6 lbs WFO. Climbed good, I have installed a new skid and have to get it transferring, but the sc is was perfect today.
Next time I am going to try 10 lbs, see what that is like.

Had my 05 RX1 MPI SC out first time last weekend. 5 PSI at 3000 RPM
10 PSI at 6-7000 rpm 15 PSI at WOT I was attempting to trail ride so the
WOT part was never more than 1-3 seconds WAY TOO FAST for tight NY
trail with rocks/boulders/trees etc. Had some install related problems but
thanks to help from MPI all should be right for this coming weekend. I
am switching to 1 to 1 pulleys shooting for 10-12 PSI max boost-which should be plenty!! I had 1 brief chance on a lake- at 70MPH this thing will hang the skis a foot in the air-INSTANTANEOUS RESPONSE-this is with stock clutching and 96 stud-shorty

Yes, 9 hours, no troubles.
MAKE SURE YOU READ THE INSTRUCTIONS.
Too many guys slap it in and run pump gas at 10 lbs, gonna cause troubles.

Yes, I did the install. Around 10 hours. Make sure you READ everything first and follow the steps. I tried to do things a little easier, but it usually came back to bite me in a later step.

had the intercooler come off 3 times & had the upper pulley(driven pulley on jackshaft)on right side spin on the shaft both due to install problems
This time I'm doing it myself!!! Hats off to MPI great kit(it delivers as promised). Follow instructions carefully/take your time-it will be well worth the effort

Rode revy again, terrible visibility, but played in the trees, and had bad snow ingestion troubles, when the hood gets covered its game over. I am thinking a snorkle, have to do some modding. Anyone tried this? Oh yeah- we were in 4-5 feet of powder when we found some nice meadows to play in.
