My only thought is possibly looking at a Centrifugal unit vs. the present Roots on the market. It would be easier to intercool later, more flexible with upgrading, but would have a little extra lag (Not much mind you) and should be lighter overall. That's my bit, lower weight. I'm prepping my TI for a DASC, but am game for other ideas.
I passed on the South Florida bit even though the price was better. Nothing against them... Miami is a tough place to get a good rep and product from (Once bitten). I live close and have only found a few fabricators that were covering all angles (Mosler in West Palm for one).

I think the supercharger is a side-business for DA. They do race fabrication. Quote: | Originally Posted by 96cali True, but price is not carved in stone.

Hi guys I will get around to answering you but we have been really busy so I will post lots of info about us in a day or so. Sorry for the wait.

Ok guys here is a big question for you. If you had to pay more for a more powerful and efficient system over a cheaper less powerful and efficient system which would you buy. I ask this question simply because of the type of supercharger we are planning to use we currently are split between the EATON M62 Roots type and the WHIPPLE W75AX Screw type. The EATON is the least efficient in terms of power delivery (tend to lose power towards top of power band), volumetric efficiency, and heat creation. The WHIPPLE on the other hand is much better in terms of power delivery (very linear power delivery), volumetric efficiency (98% which is the best of any supercharger this is not a company thing it is due to the design of the unit), introduces much less heat into the air charge. On the other hand the WHIPPLE does have to have the Oil changed at 20,000 miles with regular 5W-50 Synthetic motor oil whereas the EATON is a self contained unit but typically need a rebuild around 120,000 miles. So by using the WHIPPLE unit and a few other things we have planned we can build a superior supercharger system too anything else on the market (Not braging, this is based on a few design elements if anyone would like to discuss these with me feel free to email me at jester4982@Aol.com , greg@seambmw.com , or PM me or you can AOL IM me at jester4982 .) I will be posting a company bio by Monday for all of you to read because I have read and heard from a few of you that you have been burned before and by no meens am I trying to do the same and I look forward to working with some of the more local members on design and development work on this system once we get a few decisions and design kinks worked out. So if we go with the WHIPPLE unit you get a better system but it will be more costly. If we use the EATON it will be better (again design elements) but not as good as the WHIPPLE (By quite a bit) but it will be cheaper. I dont want to quote pricing at the moment because I dont know the exact design of the system yet with either supercharger. But based on the differences in price of the supers we are looking at a difference in price of around $400-$800. But again like it was said before you get what you pay for. Well guys feel free to give me your opinion on this, I look forward to hearing you views. Greg Scrivner SEAM | | | | | 02-11-2006, 03:44 PM | #22 | | doesn't care about you.

If you gus are making a new system , PLEASE USE THE WHIPPLE!, We replaced an m90 eaton roots with a whipple 1.6l twin screw on a e36 m3 and It rocks the differencewas like driving an M5 motor, , Hands down use the whipple.
Just my 2 cents. | | | | | 02-12-2006, 01:08 AM | #24 | | Senior Member Join Date: Jun 2004 Location: Florida Posts: 160 |

I've always been told that twin screw s/c's were the best. AA is coming out with a twin screw s/c for the e36 M and everyone on bf.c is almost in love with the thing. I would say the whipple is the best choice for power and diversity. | | | | | 02-12-2006, 04:13 AM | #26 | | Senior Member Join Date: Feb 2005 Location: Marin County & Santa Cruz Posts: 116 |

does either place more stress on the engine thu shortening lifespan? __________________

More heat will contribute to wear. The question is how much does it shorten the life. I can live with some reduced lifespan if the performance is pleasing. | | | | | 02-13-2006, 05:46 AM | #29 | | Senior Member Join Date: Feb 2006 Posts: 102 |
Good Im glad you guys agree we decided over the weekend that the Whipple was the best choice even though the price was more. I would be lying if I told you it didnt shorten the life span of the engine but I can tell you that we are addressing the heat situation quite intensively and that our system will be much friendlier than other systems on the market. If you guys would like more information on the system please feel free to email or AOL IM me at jester4982@aol.com, Jester4982 or at work at greg@seambmw.com. No we arent finished and we are still working on the manifold design but I can let you know more specifics off of the forum. Again thanks for your comments and I will post more information for your "approval"!

cool. i was going to suggest whipple since there is already a good kit using the eaton roots type. be nice to see what you guys come up with. there's a couple guys in the denver neighborhood that were talking about making a trip down  __________________ 1996 318ti, California package, 267k miles
