I have a 500efi built up to 540 with dart pro 1 heads blower pistons bigger injectors and a m1 pro charger at 8 lbs when I can get the belt tight enough. I want to go to a roots type blower.
i like the looks of a big belt 10 or 1271.
a whippile is more efficient is the 500 efi stage 2 big enough?
Is there really enough difference between the whipped and the standard roots typ if you go big?
anybody try the rootz injection system?
How much you think I can sell the pro charger for?

All this is on my 2003 26 Daytona, runs over 100 any day with a 32p

Thanks all
