MPI Supercharger - oil overheating

[snomadTT]

I finally got the Vector on the snow for a first ride. We still have very minimal snow here in the upper midwest - so the ride was limited to blasts up and down a field. My clutching is not dialed in yet - at all, so I could not hammer on it or hold it open at all before it would hit the rev limiter. Temperature was 30 degress F.

My concern is that the warning light came on indicating an overheat condition in the SC oil system. Has anyone experienced this? I've seen some builders drill holes in front of the oil cooler for more air flow - is this a must? I have not read of this problem anywhere.

Anyone with thougths?

You should have at least 6 holes drilled in front of cooler per mpi install directions, I would imagine the more air you can get to it would be better

When in doubt - READ the instructions. I did not see that. Holes will be drilled and testing will continue. THANKS!

Please send snow this way!!! Then I could get a handle on that clutching! LOL!

I did not see it in MPI's instructions to do this on the Vector either, but I put the holes in anyway. 7/8" diameter hole saw if my memory serves me correctly! Next thing is working on a air filter relocation to up behind the handlebars using the MPI filter and another filter. This will leave the MPI filter where it is at and if the hood gets covered with snow will allow air to be sucked in by additional filter behind the handlebars! Did I mention please send snow!

I saw that you had cut holes Allen - I will do the same. I have also thought about moving the air filter/cold air intake position. I am running a stock hood and light. My scheme is to butcher the hood some more (already did rider forward) to locate the filter in behind one half of the headlight carcass - leaving only the other half as a functioning headlight. I have not started monkeying with it yet, but know I am going to struggle with clearance to get a 3" pipe/hose back there. Do you have more clearance with your aftermarket hood than i do with stock?

 

[Srxspec]

I don't believe there's anymore clearance than what you would have on a stock hood. I'll try to post some pictures of the relocate when I'm done. The air filter will end up right behind where the stock speedo/gauge would end up when I'm done (between gauge & handlebar post).

I now have 10 holes in the front of my Apex Mtn and I saw a huge decrease in sc oil temps, about 40-50 degrees. Conditions were not the same as last year, but I would say a 20-30 degree reduction is a fair estimate for deep snow conditions.

Hey guys the more holes you put up front the more snow you are going to pack around that cooler= no air flow if you ride in DEEP snow all the time .

 

[Wakegod]

Good point, this is why I'm currently looking for a screen material to put over the holes.

On the other hand I spent all last season throwing snow on the oil cooler to bring down the temps...

My instructions didn't mention holes but, it does mention removing the metal piece that is attached to the hinge. I removed this and also cut out the section that SRXspec has holes drilled in.

I cut four 1" holes in the nose today. The metal deflector was taken out at the time of install. Unfortunately, there is absolutely NO SNOW to test on.

I am headed to Cooke City on January 5 regardless! I hope my pals will put up with my new sled jitters.
