From 490.4 WHP to 541.4 WHP (14.1 PSI) there were 40+ pulls. And finally from 541.4 WHP to 563.7 WHP (18.9 PSI) there were 30 or more pulls.

Well .... my original point was 150 pulls at 18 psi' s on stock motor aint happening. Your response does not show me that. Thats like saying I ran 100 miles in an hour...but then coming back later and saying ...I drove 95 of those miles....but I still went 100 miles in an hour.

Even with the numbers you posted above...the motor would not last on the street.

I never said at those HP levels that a engine would last long. Nor do I think any real tuner would you drive out of their shop with a tuned G/Z boosted to 18 PSI on a stock block. Nowell's engine only lasted 4 days in total and like 16 minutes on street. But for those 16 minutes the VQ held on

. I'm 99.9% sure if they would have pushed it to 19 PSI, the engine would have blow on the dyno.

All was doing was answering the OP question of :

I reply with the video (To show the MAX PSI), and said below it, that 10 PSI would be safer.
