Torque is 382 lb/ft (518 Nm). The model of supercharger is ASA TM1-20 HD.

wonderful!!!!! PICS PICS picccsss!! loving our little z4m Fi community and lots more new owners taking the plunge as well.. i do love those ASA units.... these big vortechs need 10 + psi to really get going!!!

I would love to see what AA would do if you got an ASA. That thing be such a blast to drive on the street and track!
... with differential 4.10 and this torque is difficult to get traction. For this reason 275/35 tyres 19.

Photos soon

The ASA TM-20 was a freaking amazing blower! The power and torque that it provides between 4000-7000RPM is very different compared to the Vortech V3Si. But it does slightly get tired on the top end, while the V3Si just loves to keep pulling and pulling.

Check out this really old thread on M3Forum! There are some valid points brought up!

great thread. I don't like the SHARP power drop after 7000rpm on that ASA blower... ugh..... can't have torque AND top end.

Rotrex C38-91?

But yeah, I am definitely not liking that dump in power on the top end! I imagine to be a big reason why ESS switched to the Vortech units. I wonder if ASA has made any new blowers or redesigned things for better top end. Considering that GPower uses the, I am still curious what their power curves look like.

ESS chose the V3si because of the following:
* it's a reliable unit
* cheap maintenance
* Internally lubricated with proof of no overheat issues on the track
* lower output temperature than other supercharger
* lower torque protects engine STOCK internals
* very reliable unit :P

the ROTREX C38-91 will deliver more power and torque in the mid-range but will require engine oil feeding and recirculation, probably a cooler, will generate hotter output temps, expensive to rebuild while the V3si can be rebuilt for like 300$ if your warranty is up or if anything wrong ever happens to it.

The max out choice would be the ROTREX VC38-91, the safe and good amount of power choice will be the V3si.

Thats how i understood it after some discussions with multiple parties that are very technically inclined.

Great information! All I know is that whether VT1-445, VT1-455, VT2-500, vT-2-550....they're all brutally fast and way more power than I can handle

One thing about the Vortech V3Si and ESS kits is how the power is delivered. I think it mimics the natural power curve the S54B32 fairly well with it's progressional strength increasing as you reach the top end. I talk to a lot of friends who have various kits with the V3Si and they all like how the power is very predictable and controllable.

yeah the v3 has lots of plus points plus its CFM rating is insane.... outflowing all of the other units mentioned including that big ass rotrex unit.... the only problem with the v3 is the inital buy price (expensive).
i love that big vortech.... its a power monster.... looking at the graph it seems this is a crank figure??? accordign to my google translator anyway!! Spot on the power anyway!!

ASA and G-Power merged IIRC. The old ASA/ESS kits cost a lot more than the newer Vortech kits.

Translated from the german wiki article on g-power:

Since 2008 G-Power is in the ASA Group integrated. This drew a move the company headquarters from northern Germany BrunsbŁttel in the southern German Autenzell after themselves.

ESS moved to Vortech because of cost, and because you can use the same blower for stages 1-3.

AJ told me they moved because they wanted a unit that was flexiable on power and able to power all 3 of the stages ( and then some).

from one of my slower runs, against an AA tuned 135i



I think I ran a 12.6 and he ran a 13.09 or something like that.
