they make them for everything else why hasn't someone made a supercharger like the weiland ones for our cars, our low coompression heads should be great for one... has anybody attempted to have one made? i ust think my 73 century would look killer if i had a blower sticking out through the hood and it wasnt on a chevy 350... who knows maybe one day..
Blowers look cool but a Procharger or turbochargers are better for a street car: Here is a twin turbo buick 350 that is about 550 HP with no internal mods other than a camshaft. http://www.v8buick.com/showthread.php?t=99527 Here is a Buick 350 that is 422 HP NA with low compression and 630 hp with a few PSI of boost: http://www.youtube.com/watch?v=zktYY...KuiWwBNoTF8XxC http://www.v8buick.com/showthread.ph...highlight=1021 Here is a 1021 HP Buick 350 with stock ported intake, ported heads and only 355 CID: http://www.v8buick.com/showthread.ph...highlight=1021 Here is a Turbocharging article I wrote based on the 350 Buick: Right click and "save picture as" so that you can open them in a picture program and zoom into them.
been there, done that. go to the bpg site and look up our little 350. it was fun, but you need a good cooling system because of heat.
Talking strictly from a power prospective I disagree. For street use there is no substitute for instant full boost from 2000 rpm to max rpm. I'm specifically talking about the Twin Screw supercharger, Lysholm, Kenne Bell, Whipple and the hybrid style Magna Charger/Eaton superchargers. The Procharger and the turbocharger are both centrifugal compressors where the output is proportional to the square of the impeller rpm. That means the boost pressure for the Procharger is directly proportional to the engine rpm since it is tied to the crank. In most cases you start seeing boost around 2000 engine rpm, then it increases as a straight line to the max boost at max engine rpm. If you look at compressor maps for turbochargers you will notice that most maps aren't wide enough to support a constant boost level for half the engine rpm range. For the street you are looking for "Area under the curve" or average power and that is where the Twin screw superchargers excel. OK, so someone is going to point out that the 1st post was referring to a Weiand type supercharger which is a roots blower. Picky! Picky! For low boost street application they can be made to work well also. Paul
I love the twin screw supercharger on my daily driver as it has great low RPM Torque. With the 350 though a better match for a street car is a twin turbo setup... Why waste HP turning a supercharger when we can have virtually free boost with the turbos?:laugh:
Sean Which supercharger are you running. Can you post a picture? Not so free boost if you are using a "You know what" type exhaust manifold. See, I can't even type the word. Why did you leave me such an opening? You knew I would have to pick. LOL Paul
I am using a Whipple Supercharger on my 6.0L powered Chevy truck. These are the type of headers I am using, mine are the same style but a little nicer:
All of the supercharger can be made to work great, but for my money, the turbo charger is king. When set up properly, they can create more midrange torque than the others and offer a boost adjustability that is just much simpler and diverse than the others. I will say that I do love the simplicity of the Centrifugal supers. If you have room for it.
say what you want about the hair dryers, i'll take a regular ol' s/c anyday. a) s/c intake, b) s/charger c)assemble on engine d)run car. don't have to 30 thousands different item to assemble. here is something for all of you. i put all what i do online. no bull****. guys in the northeast will back up what i do because they have seen it. all i here on this sight is bull****. i think its time to prove your words.
Try Hampton blowers in so. Calif. He might make an intake for you. Tell him that JESUPERCAT sent you. I could take him a 350 motor when I go, I have plenty of extras. He will be making one for our TA 455 Nitro motor soon!
One thing. If turbos and centrifical superchargers are SO great then why doesn't the top drag racers use them rather than a roots style blower? Tim
Unfortunately as far as NHRA premier classes goes, they won't allow any other types of blowers They were just about to allow the PSI blower in the TF classes in the late 80's early 90's and put a hold on it until they came up with better rotors. They came up with billet rotors and then NHRA still put the clamps on any inovations. So much for an "unlimited class"
I'm a newb when it comes to all these (classes) for drag racing but i really don't see a point. What ever happen to run what you brung???
NHRA says they're trying to control the cost of racing as well as keep the speeds somewhat under control, neither has worked all that well. The guys with the money will always spend more time & money tweaking a legal combination to the max. Is 300mph really much safer than 330? Probably so on a short shutdown :shock:
