I ran for a few years on the stock bottom end, before finally getting a forged block. I didn't have any problems at all, and it was my daily driver.

i suppose running FI on a car wouldnt really have any negative effect as long as you stay out of boost, correct?

It shouldn't at all, but it is almost impossible to stay out of the boost when you have it. LOL. The real key though is having the proper tune. At the time I was running 475 RWHP with a Brenspeed tune. I didn't abuse it, but I didn't pamper it either.

10 psi for some 6 years now. 33,000 miles with the blower, 45,000 on the motor. I don't make a lot of 1/4 mile passes, but I treat ever red light as if it were a Christmas tree. It would be an old lady in a town car next to me, but I'm still going to lay the smack down on her ***!

Acerbus 2.0

18k+ miles with the Paxton NOVI @ 8-10 psi. Car put down 486rwhp, 382rwtq with the mods in my sig. No problems whatsoever with the engine so far. The transmission wasn't so lucky, though... I drive it spiritedly everyday, but no more "top speed" runs for me anymore.

And recently I've taken up using at least 1/3 tank of (sweet, sweet smelling) Sunoco 100oct unleaded fuel at all times, as an extra precaution. I'm going forged block eventually, but perhaps an FRPP throttle body + intake manifold may be in the near future.

I think I'm gonna call brenspeed and see if they'll finance that Roush 560R

xx10Gt

yeah i understand. im thinking of either supercharging either the '10 gt or '03 gt. i kind of want to throw a whipple on the '10, but then again with me being capable of that much boost, ill probably need a forged bottom end, haha.

72000 + miles with SC added at about 47000. 7 pounds of boost at 410 RWHP.
Very Spirited driving on a regular basis.
No problems so far with motor or auto transmission, and its still a blast to drive!
