Looking for dyno chart

Hi all, it's probably been ask a 1000 times but I can't find it and got bored of searching so I thought that maybe one of you guys could send me a dyno chart for Active Autowerke E46 330 Supercharger Kit Level 2 so I can compare it with other supercharge on the market. I'm looking for the torque curves especially. FYI I'm comparing this kit with the ESS M54B30 TS2 series system. This comparaison has been made several time on the forum but I didn't find any "winner" between the two so I guess I'll have to make my own reasearch.

Thanks

IMO, if you have the money, get the Twin Screw. My rotrex S/C will only built max boost at 7000rpm where the TS would do it at like 2500 rpm lol.

Is't twin screw linear too? I thought they just have a **** ton more torque and the power band is more ridiculous then centrifugal.

Twin screw ftw though...

This is focused on Whipple but applies to the TS in general:

I include the link as it provides a good graphic highlighting the fundamental difference in boost curves between TS and centri.

I think by 'linear' SC vendors just mean 'predictable', as opposed to the wild 'kick' of a big turbo* when it finally spools. Either SC type will be linear in the sense that the the gas pedal always does what you expect.

If "powerband" means "the RPM range where the motor feels strong", then:
  • the twinscrewed motor's earlier-RPM full boost development and corresponding flatter torque curve will mean that it just about always feels strong.
  • the centried motor's later-RPM full boost development and corresponding slanted-upward torque curve will mean that it won't feel quite as strong at lower RPMs.

It's open to debate as to which which type is better in a race (which is generally won or lost at high RPMs) but a twinscrewed motor will feel consistently stronger in day to day driving.

*a turbo setup that is right-sized for driveability will be predictable as well (e.g. the TT Turbo). It won't spool quite as low as a TS, but makes a bit more power for the same boost.

OP needs a Technique Tuning kit. Boost comes in early and Never let's up.

As for turbos, the TT tuning kit is a great example of a "right sized" turbo in my opinion. Sure, you can use bigger turbos for more peak power but that comes at the expense of a longer spool time and thus very different power delivery. In terms of ultimate speed, more power is more power... but you do have to keep in mind your primary usage of the car and how you want the power delivered. Frankly, this last statement is key when choosing between any form of FI whether it be turbo, TS, or centri and to a large degree also applies to the sizing of the components in those varied applications. So often people get too wrapped up in peak numbers.

^^^ Totally agree. I can't wait to to go stage2 with this turbo. It's going to be absolutely fun!
