To me u just more pleasure out of beatin a Boosted car an ur all motor . Almost like beating a guy in sports who takes steroids an ur all natural lol...
Okay, this thread is a bit old, but seeing as I just read the whole thing I think I'm entitled to drop in my .02 of thought here.

To make an NA 3800 as fast as or faster than the supercharged 3800 car does take a lot. On paper, it looks like your GT is only 40 horsepower and 40 ft-lbs of torque down from the GTP. Hey, that isn't much, right?

But the fact that the blower helps put the torque out through more of the power band means you will need to make a lot more with your NA car.

I'm going to say this cliche: There is no replacement for displacement. But blowers and turbos will give you MORE displacement, period. The best you can hope for with normal aspiration is to make your engine less restrictive/more efficient. But you'll end up needing a lot more money because you'll need to stroke that engine, get the best possible flowing heads, a perfect cam to let the engine breathe in the upper RPMs, and the proper intake and exhaust mods.

And you will spend thousands of dollars to get there.

Maybe this isn't what you want to hear, but it's pretty much how it goes.
