MCX mounts right onto the motor behind the the oil reservoir, into the PTO I believe its called. I think the oil pump on the Trask kit is/was near the turbo and thats why it was prone to overheating. I haven't talked with my buddy in awhile about his sled, but I do think that Trask is aware of the problem and has it fixed. But im not sure. My buddy went through 3 oil pumps before they figured it out. He bought one when they first produced them for the Nytro. If I remember correctly he now has it up above the oil reservoir and has had no problems since. Last year raced up the drag race hill on boulder in revy, mine would pull slightly on him. He upgraded to a 162" track and Apex springs in the rear, I was still running the factory crap maverick 153" track stock rear suspension. He was running 7lbs of boost, I was running 6.5-7lbs of boost. I have been told I should be pushing 8-9lbs at that altitude. So we'll see how they both run this year.
