Look what arrived today.







Can be some small fitting space issues.

Jesus man, you're crazy. Leave the poor car alone for a time being.

or this time with a stroker engine?

Thomas you need to find help

[Settari]

Nice!

[Majorcina]

Wow!

[Thuppu]

Hahaa, thanks guys, appreciate your view in this matter. Just can't leave it alone, need to evolve things even that the previous version wasn't finished properly. Where can I get help?

Nick, I doesn't have any schedule for the next dyno.

Thuppu, why did you replace the Eaton M90 ??
Did it produce too much heat for those boostlevels ?

The M90 was working good and boosting well from down low. But it was also quite heavily transmitted and was turning 18500rpm at 8000rpm engine speed. It was out of the efficiency map and was producing lots of heat that occurred espeasilly on track. I'm sure it would work well with a bigger pulley(less boost) and make less heat = more power. Well, it did make 624hp, quite good result for a twincharged engine with massive torque at 2krpm.

But my goal is now to make a twincharge setup with efficiency without compromises and for even higher power levels. M90 alone is good for max 350hp, M112 ~450hp. I will now run the M112 for about max 11krpm so it will be on the good area of the efficiency map. It will propably make less boost on low rpm, so maybe some small drop in down low torque, but midrange should be better with big size turbo.

Timing belts. Gates standard vs Gates Racing.

At the time I ordered it, Gates racing wasn't available here in Finland. Now there is one shop that sells them, but I guess they have like 4 weeks order on them.
