GTO Failure from the Goat's mouth...

It's boosted. Remember, 14.7 psi boost, at a comparable air inlet temp, will double torque (and thereby horsepower) at a given rpm, assuming everything else is equal (and that is a huge assumption, which never equates...there are pumping losses and more).

11.49 and faster is the current roll bar/cage requirement.

Fun to drive and a little scary on street radials
The stock bottom end is good for 650 hp, remember these things only rev to 5500 max stock, 5000 is like shift point...torque!
In theory at 14.7 psi boost, the 231 is equal to a 462 in displacement, I'm running 20 psi so I'm looking at 545 ci All this is lost in VE and head flow numbers but boost still rules. My stock turbo was still running strong at 88,000 miles when I finally upgraded to a more efficient turbo, the last piece of the puzzle.
That 'flash in the pan' is still burning @sses
Still a turbo car requires special care, oil has been changed every 1500 miles, it is allowed to idle at LEAST one minute before shut down to allow the turbo to spin down and oil to cool, and the fans are run on the cool down ride and the engine temp is brought down to 160*, just my anal ritual. These engines came from formula one or cart whatever in the '80's and detuned for the street(not the same engine specifically, just same concept Buick V6 Turbo)

Yeah this is my forever car, no doubt...it was ugly, bland, and overpriced when I bought it
