New 305" Whipplecharger
I know it just came out this January but does anyone have any info on this unit? Its a direct replacement for GMC style roots blowers. Seems like a good option for an efficient supercharger that will work with existing blower manifolds, linkage, etc.

With an adiabatic efficiency of 75-76% its right there with most centrifugals and turbos, but with the low end boost of the roots. Now if I could just get it to fit under my hood....

Lets see, call Bob or Frank at AllPONTIAC FOR BLOCKCrank, etc., call for this new blower, get everything in, together, and into car. go to track,get throwed out of gateway for running too quick, grin all the way back home.
 Clearly worth checking into doing!!! |

Art and Bennie have been playing with the larger supercharger for some time.
I know of a couple of "projects" where that unit is being tested. LOL! Glad Whipple is doing something in that area for larger engines. For a street car the unit would work great. The older 3.3 Liter unit would move about 70 lbs of air/minute so the 5.0L (300 cid) unit will move more naturally. 70 lb/min is 700 hp before you take away the 125 hp to drive it. 3.3L would make about 575 at the crank. 5 Liter blower will make more, like 50 % more so 575 + 285 more = 860 hp. Lots of centrifugals will make more HP on the top but the Screw will make great HP in the Pontiac rpm range of 1000-6000 rpm. Tom V.

Tom, Would this be the supercharger to use to make a solid 2000 hp with?

Nope, WAAAAY too small. Just a good street piece. Unit will just not move that much air. The PSI blowers will make the HP though.

Food for thought, a 6-71 roots blower has around 400 cubic inches of volume per revolution. Pontiac Jack had the real numbers at one time, I can't remember what they are right now. I know that blower will not make 2000 hp so how could a 300 cid screw blower make that kind of hp.

Screw Superchargers rule all!
Great Article on Norm Drazy: http://www.northernthunder.com/turningscrews.html Whipple probably should've designed this a little bigger/inlet looks less efficient than what Norm Drazy pioneered... Drazey told me after the screw supercharger blew up and NHRA banned the PSI design(RCD made pulleys to spin the cast rotors faster than Norm suggested ...Troxel?http://youtube.com/results?search_qu...&search=Search) that he made the screws out of billets and the PSI wouldn't explode at max RPM but actually sieze(33000 or so RPM). So depending on what material Whipple has used for the rotors and actual max rpm, the air volume amount seen in the manifold/hp can possibly go up a bit more. Yea it's not a 2000hp setup, unless you ran maybe two of em...Quads. http://www.whipplesuperchargers.com/...sp?ProdID=1179 -Rob WWW.ICTCengines.com |

Just add a shot of n2o to get that 125hp back

They are certainly not cheap. Whipple has set the MSRP at $6,350 for the base blower (no drive system), $8k for the blower with a 16 rib serpentine belt drive and $12k for a top of the line intercooled model.

Rob,
Norm came to see me about 5 years ago and brought a blower with him to show me. He hauled the thing into the building on a two wheel push cart, LOL! Yep! Norm is a sharp guy. I heard a rumor that Lysholm was sold or in the process of being sold. I guess Art, Corky, and Jerry have been kicking their butts on sales. Tom V.

I could swear that I've seen info about a guy running twin whipplechargers
in a pretty radical and rare Buick GSX car. I think it was a street strip car that ran 9's. Can you say TwinWhippleChargers 3x fast ?

$6350 for just the blower? Yikes! That's alot of money for a small blower, even a new one. There's a 14-71 standard helix Kobelco that was refurbished by RBS right now on EBAY with a buy it now price of $2800. That Kobelco will support a sh!tload more HP than this Whipple.
