    Default Hampton 2 lobe blower

    Disclaimer……I don’t know half as much as I’d like to. I’m open to all Criticism.
    I’ve wanting to post this thread for months now. For whatever reason, I can’t seem to find much information on this blower.
    We….on the PB forum have awesome talent that love to teach.....which is very rare.... Every day we are fed information that most have to pay for……….having said that…………with all due respect to those that view this thread……I've grown tired of the bullsh!t that surrounds most blower threads……In other words….im an not asking about turbos….im not asking about belt driven turbos.
    I’m not asking about hi helix blowers. I’m not asking about v-drives……jets…or outdrives…..I sure as hell ain’t asking about egg beating weed whackers!
    The only thing I’m asking is…. Does anyone have any (factual) information on the Hampton Super II?
    In my very limited understanding, it sounds like a great HP to cost option. An 8-71 is supposed to work like a 14-71 three lobe blower less maintenance. Anyone have any thoughts….per cost?

    On his website he guarantees it. Looks like a few heavy hitters have been using it in competetion. Looks like a non-stripped blower also.

    Guarantees what exactly. Compared to what EXACTLY?

    Let it be known that I would never say a bad word about Don Hampton, Gene Moonyham or Don Bowers. Period!
    BUT,
    no 8-71 is ever going to act or move the air of a 14-71.
    Its old school. All roots blowers were straight 2 and 3 lobe blowers when they were first invented. The twist was created by GM starting with the 4 and 6 71 blowers. All small roots blowers in the 50's were straight. Most small blower like the Weiand 144 thru 250, including the Weiand 6-71 are 2 lobe straight rotors. If a 8-71 with straight 2 lobe rotors will out flow a 14-71, then why does Wieand bother to make a 8-71 with twisted rotors. Doesn't it make sense that the 6-71 with 2 lobes will out flow and out HP their own 8-71 with twisted rotors? Are they stupid?
    They used straight rotors in drag racing in 6-71 cases for years before they started producing cases for larger blowers. Once the larger blowers were available, the straight rotor vanished.
    It very simple. A straight 2 lobe blower will move more air that a twisted 3 lobe. GUARANTEED! But a 8-71 2 lobe out performing a 14-71? No way!

    You say you don't what to hear about hi helix, well then stop reading!!!!
    When Norm Drazy arrived on the scene with Lysholm design screw blowers that were big enough for top fuel and alky classes, the roots was done for. Period. But the NHRA banned screws from Top Fuel, only allowing them for alky and gas classes. It was more than a little obvious that the screw was FAR superior to the roots, but illegal for fuel. So they did the next best thing. They added even more twist to the rotors and a delta opening in the bottom. They went from a 60o twist to a 120o twist.

    THERE IS NO RULE THAT STATES YOU CANNOT USE A STRAIGHT 2 LOBE ROTOR IN TOP FUEL!!!!!!
    So then why isn't anybody using them, if they are gauranteed.

    He guarantees WHAT exactly, and compared to what EXACTLY!
    Like I said, I would never say a foul word about Don Hmapton, but you may be reading something into his claims that he never made. I think Don is intelligent enough to know that his 2 lobe blower has no chance against a Kobelco, SSI or PSI roots blower. And I am fairly sure that as well known as Don is in the drag racing world, that if his blowers made more power than a Kobelco or SSI, Force and Schumacher and everybody else would know it. Don was one of the very very best in the top fuel blower field. Nobody knows what it takes to build a winning nitro or alky blower than Don, and I assure you he will not make any such claims about the roots style blowers that are currently use. They a world apart.

    Look at the way this thing is built, and tell me that a simple standard 14-71 with straight rotors is in the same league with this. There is more enigneering in the rotors, cases and inlet inserts on one of these than you can imagine. There is a reason they are the KING, and why they cost what they do. There was a time when Gene Mooneyham, Don Hampton, Don Bowers, and Kuhl ruled the blower field. So did iron block 392 hemis. Those days are long gone.

    [QUOTE=gn7;1613564] A straight 2 lobe blower will move more air that a twisted 3 lobe. GUARANTEED! But a 8-71 2 lobe out performing a 14-71? No way!


    The Hampton II does not have straight rotors. It has billet twisted two lobe rotors. Which would make it illegal for nhra use. This is also why it can't be compared to a hi-helix kolbelco, a screw psi, or an old school weiand. The hampton II is it's own thing. Correct me if im wrong, but top fuel guys are allowed to run billet blowers but I believe they have to be 60 degree twist. That would make any hi-helix or screw blower better than they have now. If top fuel guys were allowed to run this blower over a three lobe 60 degree twist do you think they would?

    Do you have any ideas on pulsing because of the two lobes?

    Would a blower designed this way affect signal at the carbs at idle compared to a three lobe?


    If I cant re-find the chart that shows how much air they move i'll post it. Im having a hard time finding it.


    thanks gn7

    If there is a twist in that thing, is sure is EXTREMELY SHALLOW.
    There is nothing that says they can not run a 2 lobe rotor in Top Fuel. Certainly not in Top Alcohol, or Pro Mod.
    Billet rotors are manditory, not just OK. 120o twist hi helix rotors are OK and used, as is blower setback, and Delta openings. It all simply has to fit in the 14 case with a legal rotor length, and case inside diameter.

    With the million at stake, and the millions inn their war chests, all the top fuel and top alcohol, and Pro Mod guys have managed to over look somethng you just happened to discover from one of the oldest blower manufactures in the country. Damn do they ever look foolish.

    Get ahold of Andy Dement he tested 1 on his TAF and had great feed back.... He runs a Hampton 14-71 then tested it for Don a few years ago..... If you dont have his number I could arrange that for you. Tom

    Ok I got the data... Its a 2 lobe blower with 60 degree twist. Accourding to don a typical 14-71 will move 519 cubic inches of air. The Hampton Super 2 will move 619 cubic inches of air per revolution.

    I don't see any reason why a delta opening and setback wouldn't work with this blower as well...

    And yes you are right....if top fuel isn't using it, its for a reason. At any rate Im just bench racing. Its an expensive piece, but for the price I think its a cool idea.
