450cc´s at 50% duty@5k and it´s only 0,45bar boost :mad: :mad:

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! :twisted:

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

Got a tax disc today, so everything is sorted.
took it out, it´s maxed now :cool:

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.

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.,

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

Image

And this is same boost but after tuning.

Image

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. :)
