Yeah, them Pre PI 2V's dont respond to boost like the PI 4.6's do. And they dont seem to handle it all that well also.

Some Pre PI 2v's (With Pre PI heads and all...Dont want Hammer killing me) with a blower on it only make a little more power than a slightly modded PI 4.6.
LMAO
Actually, it's been my experience that while the 99 and up modulars put a bit more HP to the pavement with a blower than an early modular, the early modular setup seems to "live with" the blower a bit better.... It might have something to do with the compression differences...

Actually, we did a side by side dyno of these setups....
98 with FRPP Heads\Intake\Procharger (Yellowjacket) against a 99 with PI Heads\Procharger....

I came out ahead by about 24-26 horses (rear wheel) with less compression and running dog rich.... While not a great bang for the buck.... There IS a difference between the FRPP and PI pieces.... Now with the porting used in SD Wheeler's package, we could be playing with some different #s here....
