We appreciate everyone's incredible patience with us developing our Gintani Twin Turbo E9X M3 Kit. We figured we may as well start a new thread as our previous one has a lot of clutter in it. We are working very hard to finish production parts and release the kit by the end of summer.
We took our TT E90 M3 to a local dyno, Specialty Z, where they use a Dyno Jet. The car is currently running at 7.5 PSI, 91 octane, stock motor, and stock MSS60 ECU.
We did a comparison from our Twin Turbo Kit versus our Supercharger Kit, both at the same peak boost of 7.5 PSI:
Car and Modifications:
- From 3200 RPM to 4500 RPM – The Twin Turbo makes 60+ WHP more vs SC.
- From 4500 RPM to 7000 RPM – The Twin Turbo makes 90+ WHP more vs SC.
- From 7000 RPM to 8300 RPM – The Twin Turbo makes 50+ WHP more vs SC.
- From 3700 RPM to 4600 RPM – The Twin Turbo makes 80+ WTQ more vs SC.
- From 5500 RPM to 6200 RPM – The Twin Turbo makes 100+ WTQ more vs SC.
- From 6200 RPM to 7200 RPM – The Twin Turbo makes 60+ WTQ more vs SC.
- From 7200 RPM to Redline – The Twin Turbo makes 40+ WTQ more vs SC.
