sorry for finish :)...some new stuff+pics etc.
Now currently adapting new polychain carbon belt system to get some nice whine and traction for the blower. Hope to get 370hp out of the engine with this system+new custom exhaust and ITG filter.

During the winter maybe I´ll make 2.8L stroker mod + add more agressive camshaft and other things to get the power up to 400hp(hopefully). Then I would think it´s there where it should be ;)
Cheers, Sami
