I Just figured you're such an important guy, they should be capitolized...LOL I didnt get a chance to check the bypass yet, no one wanted to ride in the engine bay while Im boosting down the road....

Mine does not have a PCV valve at all, its all internal....or is that what your talking about? I really think Im just overspinning this blower, or its not large enough for this engine. How do you calculate blower RPMs? Im not sure what the crank size is on this engine, i will have to look it up of crawl under there and see.

I safety-wired mine shut once to test it. It was BIC (before intercooler), and man, did the IATs zoom! Also, it makes a real cool noise when you let off the gas.

You could do like Dusty did to see if his blow off was working and duck take a video camera under your hood and go drive around

Are you talking about this?

BTW. I vote for a sliping crank pully.....

Thats pretty cool Dusty. How can i tell if the crank pulley is spinning other than pinning it then trying again? How are the pulleys pinned?

I know if i can get a few more pounds of boost outta this thing, i could be flirting with low 13's.

Take a sharpie and put a mark on the crank bolt and crank pulley. Go for a few blast and see if they are still lined up. That should tell ya if the pulley is spinning.

perfect, but I gotta say, if it was slipping, you more than likely would have erradic boost readings. Not super stable like you do now. I said more than likely!! I bet I am wrong. ...the sharpie trick cost nothing though. Unless you are The Breeze who wouldn't write on the motor, that's a suuupppeerrr dooooper idea.

I beg to differ on that one. Once the starting friction has been overcome, it will continue to slip as we see with his log. He peaks early, then loses boost.

Just my .02.

Whoaaa whoaaa guys take it easy there....no need to go at each others throat like this. I dont want to see anyone say anything that might come back to bite them....... j/k, just messing with you guys.

I will try the sharpie thing for the hell of it to see what happens, i like that idea even if its not a crank slipping. With my luck it would be slipping, but lining itself up perfectly with the mark everytime it stops....LOL. How does the pinning kit from maggy work?
