BMW Supercharger Specifications Wiki
Recently I've been doing some research on a project for higher horsepower supercharged M3's -- even higher than current VT3 specifications. I knew Vortech had just announced a new V2-TI supercharger at the 2013 SEMA show. But so far, I haven't found any specifications for it from Vortech, or on any of the review sites. So today, my curiousity got the best of me and I called Vortech to get the specs.
At first I wanted to compare the V2-TI specs to the typical V3-Si and V7-YSi specifications, but then I thought...why stop there? Why not compare to all the superchargers that have been offered in the past or are currently offered on the S65 M3's. So, I compiled a list...and here you go.
Notes:
Please don't use this thread to turn it into a vendor war of whose supercharger you think is better. I'm really hoping it won't turn into that. I'm hoping it will stick to a technical discussion. If you see any errors, please help me correct them. If you know of other supercharges that have been used, then please mention it and I will add it to the list. Enjoy, I hope this helps people.

I do not see the V2-Ti compressor map posted; just the old V1-T versus V1-S map. Looking forward to some dyno testing of the V2-Ti to see its advantages on stock block motors as well as built motors.

First I have to figure it out. I guess it's time to read the Vortech white paper on reading the compressor maps! |

Here's one thing I forgot to mention about the V2-TI and why it's worth talking about. The V2-TI will go up to 1000 CHP, but takes up no more space and mounts to the same brackets as the V3-Si. That makes the V2-TI a great migration path for people using the V3-Si (like ESS and Gintani stage-2 kits) and wanting to build their motor and upgrade to their stage-3 kits.

Yes, all but the V2-TI because it's brand new to the market in the last two months. All of these have been used in the past, or are currently in use on the S65.

Oh okay true. Not too many blowers, I guess the market opens up for suppliers to add value in the tuning, intake manifold development, and cooling department. Thanks Reg Guy ur info and work for the s65 on this forum is helpful. no h0mo

a company called 928 offers billet wheel upgrades for the v3 units that bump up the CFM to 1200...... this is a great option for v3 owners wanting more from their supercharger unit....

Great info! I'm definitely interested in how to understand the compressor maps and get to know each units efficiency range better.
Have you tried to collect any data on the Eaton TVS TM 1740 planned for implementation from Harrop or the ASA supercharger utilized by G Power? I think the unit is the T1-723, but I could be mistaken. |

EDIT: I already found the specs on the ASA T1-723 and confirmed it's the G-Power unit. I will add that tonight. |

It looks like G-Power has used both the ASA T1-523 and ASA T1-723 on the S65's. I found specs for both. So I'll add both.
I'm having a hard time finding specs on the Eaton TVS TM 1740 or anything Eaton 1740. It looks like a new unit and specs don't appear on their web site. I have sent an email query. If it's successful, I'll add that as well. |

The older T uses a larger inlet, although the discharge is the same size. The larger inlet meant that the same intake could not be used unless it was cut back and a silicon adapter put in place. The difference was only about 1/4 inch. Not sure about the newer Ti, but I assume it is also larger. There is another designation for clipped impeller wheels, the older SC and the newer SCi, but there has never been a clipped version of the T and I doubt there will be one for the newer Ti. VF has used the clipped wheel blowers in some BMW applications, but I do not know about the E9xM3. I think the theory on the clipped wheel is that it spreads out the flow for high revving motors so boost does not go too high. The V1/V2/V3 designation specifies the internal drive. V1 uses sturdier straight cut gears with a 3.45:1 step up ratio and require an oil supply and drain. V2 uses the quieter but weaker helical gears with a 3.60 step up ratio and require an oil supply and drain. V3 uses the quieter helical gears with a self contained oil supply. The YSi steps up to a larger case blower. It fits in the same brackets as the V1/V2/V3 but is physically larger in some areas, so whether it fits a particular car depends on the space in the engine compartment. |
