Bernd's Tubro NC
 
Here You can see a really serious project.

This NC is getting a Borg Warner EFR7163 turbocharger on a forged engine running with 1.3 bar boost tuned with a MS3. It will produce around 400hp at the flywheel with 455Nm/336lbft torque.
It also gets a full roll cage, fender flares, gearbox oil cooling system and differential oil cooling system.

A forged 2.0? What manifold are you using? What wheel and tire specs?

Guido@SPS 12-18-2019 02:34 AM

Hi, the manifold is custom built with an external wastegate. Tires are 255/40 ZR17. Wheels are 9x17 Rota Titan with 42mm offset and spacers.

And this is a dyno sheet with 1.4bar/20.3psi. The power is at the flywheel.
