That is such a nice looking engine bay

Thanks! There is some hours behind it

For this size turbo a single 044 and some 850cc injectors would work fine on e85.

At the moment i run on 1000cc Bosch EV14 injectors. But how much can a single 044 pump give me on E85 you think?

Some carbon

Couldn't resist to buy some carbon from Aron. Also fitted my turbo heat shield.

I am not sure how you arrive at the 28% drivetrain loss (483 stated hp).
I usually tend to see 20% on these cars. And 378whp would be ~454hp in that case.

That said, on 98 RON this is a perfectly normal result. There is not much use going more than 1.9-2 bar on pump fuel. Result is only heat and detonation.

I don't know what the dyno's ramp rate was set at, but the spoolup seems a little late.
A HX35 Super makes the same power and has 2 bar at 3.9-4k.

WMI or E85 would help a lot. In fact I don't see why you don't use E85 with dual map switch if you are in Sweden, as E85 is almost more common than 98 RON over there.

That was me writing wrong... The dyno sheet is "correct" . I don't know anything about their dyno ramp rate. what is that?
The reason i decided to go with gasoline was that i didn't have to build a new fuel system. Just dropped in a 044 and new filter, injectors. Maybe in the future i will change to E85 but for now it's going to run on 98 gasoline.

So what was the limiting factor stopping you from making more power?...

The tuner said that it was a gamble to push over 2 bar with gasoline. And the exhaust temp was going up to much. We went up to 2.3 bar but with no big difference in hp. The tuner blamed the fuel.

wow impressive on the torque jumping from 3.5 to 4.5k rpm.is this BB or journal bearing CHRA?

Hello. It's just a journal bearing. Precision 58/58 turbo.

Flywheel

Great progress / result. Looking forward to a drive by video.

Can the flywheel be used with an em clutch ?

I presume the flywheel is lighter than the AAN flywheel ?

Thanks.

The flywheel is used with 707 Sachs pressure plate.
Yes it's Lighther than AAN flywheel. But How much i don't know.

A little video from the dyno

Thanks

Thanks for the kind words. I'm really enjoying the car. It pulls lika a train as far as you keep the revvs up. I will polish the car tomorrow because it's worth it now.. In the weekend i will put many miles on it and hopefully i can find some old gentlemen in their porsches and smoke their asses
