No Paul, BadSSEi puffed out the engine compartment. After one race the engine compartment was wet with sc oil.

Now I know why my under hood insulator is oil soaked directly over the snout.

I suppose these SC are only designed to hold 7 psi of pressure without blowing out the seals.

Not all of them.

But then again, mine doesn't have a breather. I've been running somewhere between 12 and 15 psi on mine, but without a breather like yours, I won't have the problem.

I've seen other Pulley'd M90'* not leak.

Ok..so Paul got a model clearly intended to peeve off a Canadian.

The snout leakage has me thinking as well. I've run a 3.2 for some time now and have no oil at all at the snout. Must be something wrong...as I know I'm clearly around 13psi.

Enjoy the Gen V Paul...

Just think how much that old defective SC cost me last year in the 1/4.

2 psi has to be worth something. :P

Had a very good discussion with Snow Performance technician about my Boost Cooler injection system.
He actually recommended spraying pre rotor. He also said it'* fine to inject post rotor. Says that it does not remove the rotor coating but actually helps by cooling the rotors and creating a better seal. Says that coating loss is caused by the rotors overheating and flexing due to running much faster than stock using smaller pulley'*. It makes sense from the markings I observed on the coatingless rotor.
Also recommends not running with race fuel like I was doing and that it will give me more power.

I am going to make further modifications as soon as I get running again......but I won't tell. It'* a secret. :P

Paul, half of what he said is BS. I've been spinning a SC faster than ANYONE here, and have no coating loss whatsoever.

.....and you've been injecting with no coating loss.
A different design of SC might make the difference. Your rotors are shorter and you push much less air with the M62 vs M90.

This guy has a lot of experience with injection systems and seemed to know what he was talking about.

Our rotors are the same length. Diameter is different, but not by much.

And I'm pushing more air than an M90 with a 3.2" pulley. About equal to you wtih the 3.0". Think about it.

We've got alot of pulley'd M90'* here with no coating loss.

Are you sure? I didn't know until I pulled it off. How many that have run with a 2.9 and no intercooling have no coating loss? Should do a poll.
