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

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.
