I gotta disagree with you Brian, he actually states putting hand or book accross the U TUBE.... that's the intake. He is also talking about the breather tube, too. but the hand thing he is talking about the intake.

While I agree the end of the Utube is safer than against the turbo !!! I still think the vacuum of 5 or 6 pistons sucking against a 2.5" tube is enough to do serious damage to your hand. NO VACUUM cleaner is going to suck that hard!
