I just found out KB makes a 3.2 blower for the 3v. I have a 2007 GT 3v with a maxed out Whipple 2.3... anyone run the KB 3.2 on a 3v? I'm very interested in this as an option.
Thanks.
Thanks.
I would never go from a whipped to a on first of all unless it was going to be very low boost for the big blower due to heat issues.
Many have gone to the VMP modded TVS with good success.
The 3.2 is very new and good for about 5psi more than the 2.8 mammoth. Cool that it's physically the same size as the 2.8.
As a reference, the 2.8 on a 3V will make 820-850rwhp. Mine made 843 using stock 3v heads. Expect another 75hp with the larger 3.2.
with that said, the DOB R-Spec is the best twin screw option for BIG power! Plus it has all the extra cool features - big innercooler, dedicated belt drive, 200a alternator, etc.
With a more oxygenated fuel, like E85, you should make your goal of 600rwhp. But that 2.3 Whipple is all but spent spinning it that fast. It just wasn't designed for "big" power. For 700rwhp + with a screw you really need a larger displacement blower to keep IATs down. You have 2 options for the big screws on a 3V- KB and DOB. Otherwise a turbo will get you there easily with the right combo. I've had 4 different blowers on my car. For >850 rwhp the DOB kit makes sense for a lot of reasons.
And yes the hot rods are good for the sound, but difficult to tune and definitely hurt power. Keep in mind stock heads and cams will get you north of 750rwhp, no need to go crazy there.
