Moderator: martauto
450cc´s at 50% duty@5k and it´s only 0,45bar boost
They will probably max out at about 1-1.1bar.
Drove it around today to do some fuel mapping, it´s spot on now, just need to get "out" where I can really try some higher boost.
EDIT.
Overall this 8.0:1 compression ratio 2.8 is sucking in on average 17% more air then a 2.5 does at same KPA and RPM. So this cheap stroker conversion is well worth it.
No such thing as bad throttle response either

Great work Gunni!
It must be amazing the turbo engine!
Is there any lag on the throttle?
By the way, i love the zinnobar color and the black wheels...
Really spicy!

Who knows

There is no lag, but I´ll have more info on the boost threshold(when it comes in rpm wise)

Gaffa tape is like "the force" - it has a light side, a dark side, and it holds the universe together.
There's nothing that shouts "Poor Workmanship" more than wrinkles in the Gaffer tap

Got a tax disc today, so everything is sorted.
took it out, it´s maxed now
450cc´s are at 90% duty at just 1.1bar.
We´ll see what that is on the dyno next week.
It´s a damn monster btw.

Not in E30s any more 

there will be very soon 

That would be so useless 
it´s only got 215/40-16´s and an open diff.
traction is just not there.
My friend works at race technology and he got a video datalogging thing we are going to use today for some video/kmh/rpm/g recording.,

man thats @ucking fast! good work there!! 

Well I didn´t quite get 400LBS torque like I had hoped, but
466LBS !!! ,, This is SO crazy now.
I took the car to Sal at Evolve and had a bit of fun tuning
This is where the car was before tuning

And this is same boost but after tuning.

3rd gear looses traction now after I tuned the ignition.
And driving this is INSANE!!..
Having a car tuned on a dyno really makes a difference.
