When my car was in the mid-12's & I had had Alky on for about a month or two. I was going over to another town on a long 4 lane road at night, just to see what my boost would get & actually top speed.
I was in 4th gear 27 lbs. of boost got up to around 124mph according to the scan master but I got on it from going around 55-60 mph. Then rolled into the floor board & held it for about a 1/2 mile. No knock no problems. But again this was NOT from point A to point B. or from a dead stop to racing like you're talking about doing.
With the motor I have now I've also done the same thing to see what the rpms would drop to for about half a mile had no problems but based on what everyone else is saying I wouldn't do it again. lol.
