Yes.. a turbo is probably capable of more power

I thought this thread was about "superchargers" anyways....when i buy a blower i would like for it to be of the most effecient design possible "twin screw"

A Centrifugal design for the Titan is not what i'm lookin for...takes 2 long to spool up or make power...by that time we are near upper rpm.....our CAM profile has most of our power @ lower engine speeds. Any roots style would compliment us very well...

Yep the twin-screw design is bad 2 the bone...look at what they do with a mustang 4.6 it produces nearly 520RWHP and 550RWTRQ with 10-psi of boost, all on 91-octane pump gas! Is that sick or what...http://www.whipplesuperchargers.com/...sp?ProdID=1208

geez 520 rear wheel horsepower...that's around 630HP to the crank i'm sure

Check out this link that Whipple has on their site. It explains the principals of a twin screw design. It's a good read.

I understand the twin screw design, I was just under the impression that the roots operated exactly the same way. Whipples site talks about how great thiers is, but i didnt see anything detailing how mechanically a roots is different.

here ya go roots vs twinscrew...http://www.kennebell.net/techinfo/ge...romcatalog.pdf

Nice find! They are very similar, as I expected. Wonder why eaton favors roots if twin screw has so many advantages?

May just be a cost factor. I'm sure the screw designs are far more expensive to manufacture than the regular old roots rotors, but with the volume they sell you would think they would make up the margin pretty quick.

[mach1]

yeah, im sure your right, its all about the bottom line. Roots are probably more reliable in that they are slightly simpler design, not as close tolerance

Probably because eaton has been doing roots for so long and it works....I think both Whipple and Kenne Bell have proprietary designs.

Whipple can make a "stock" SLUG 5.4 Ford F-150 have more output than a "stock" Stillen Titan...that's depressing...we all know how slow a new Ford F-150 ishttp://www.whipplesuperchargers.com/...sp?ProdID=1203

Take a look at what happens to a ford lightning when the "roots" is swapped for a "twin-screw". 96HP by simply swapping the compressor...I hope GReddy goes this route or atleast thinks about this technology!!!

Check it out 10 sec lightnings use twin-screw..

From the article..
All but two of our competitors were sporting Kenne Bell twin-screw superchargers on top of their cammers, further convincing us that screw blowers are the way to go in the quest for serious horsepower.

If you were an observer like I’m an observer then you would be observing what I was observing…lol.my bad….time to put the pipe down..LMAO

Please rest assure that when we do start this project we will give 100% attention to the quality of the kit as well as the keeping a close eye on the integrity of the motor. Nothing will be left unturned. We have been in the forced induction business for over 30 years. Over those years we have used both supercharge and turbo charged applications. We have a strong presence in the import industry with many turbo kit applications. We have just recently stared using supercharges again in kits like the Celica GTS and the Scion XB. We are not going to put the amount of money we are talking about into R&D just to fail. That is not an option. We will succeed in a kit that offers quality and a substantial power increase while still maintain streetablity.

All of the other companies that offer supercharges or Turbo kits for that matter all R&D the heck out of the product before it gets to the publics hands. We all offer a great product. Some are different that other, but all have one thing in common: “MAKE A GREAT PRODUCT AND IT WILL SELL ITSELF.”

The reason for this rant is due to a few P.M’s I have received. I and others in my field of work are not here to bash each other company’s products, but to research what the public wants, aging by making a great product. I hope this explains my position on the matter.

Sweet, glad to hear it.

I can't see a kit going for 4k - but for 5 i can see a single turbo set up happening

Sorry but a turbo set up is not in the cards. Cost is the main factor

[mach1]

to much plumbing involved,. for a street freindly, daily driver,reasonable gains, home installed system, supercharger is the way to go

TitanHigh, any updates? Hopefully things are rollin'! Good luck with it.

Everything is still a go. We are going to start prototyping soon. Also, i have not forgotton to call i have just been very busy. I will get with you some time next week...
