Seppo.  Great numbers and reinforces why adding boost is a great power adder.  Rough math has that engine making almost 300HP in a normally aspirated setup which is still respectable even without the boost.  Thanks for providing the lb/ft torque numbers.  That helps to keep the torque values in a U.S. numbers format.

Mister Santala's dyno is quite hard for them who want to get big numbers.
Many brand new crate motors lost power during ship transport from US if you are looking what stands in selling brochure.

956.4 horsepower @6300 rpm and 1164 Nm / 858 pound foot of torque @ 5400 rpm. Boost 2.2 bar / 32 psi. I thought HP is universal value .
