This is altogether superb my friend. Just read through the whole thing here and it has been enjoyable.

So, now I have 290HP at the engine and 270HP at the wheels and 41kgm of torque.

This Saturday I tried the APR 98oct and 104oct software.

I had to choose the 98oct because with the 104oct the lambda meter was showing the AFR trying to be stoichiometric and not rich how it should be at full throttle.

So, now I have 290HP at the engine and 270HP at the wheels and 41kgm of torque.

Almost...

I'm happy with the gain of power after 4500rpm, it is helping, but it is not enough, I'm going to test as soon as possible a more aggressive APR software.

I'm using the 95oct software, I'm going to try the 98oct and the 100oct. I will see what can happen. They have a tool called V-tune, it is capable to make adjustments over the software.

Are you happy with the feel of the car now?

[Plautos]

Here we go!

The car lost the peak torque, however it gain more torque after 5000rpm.

The last graphic is a comparison between torques, I plotted the new torque curve over the old one.

We should remember the boost is falling after 5000rpm.

New shocks for the rear...
These shocks are from VW Corrado... I had to tune it a little to make it fit..
Thru the pictures it is possible to see the Konis have a shorter stroke, at least 20mm.

Lets see on the track if it worth it.

You sure do love your hybrid turbos Do you mean you hit the Eclipse???

I mean I had to overtake the Eclipse.

I was thinking on the GT28RS with the compressor housing from a GT25, but I need more handling first... I'm sliding too much in hi-speed turns... and this gearbox is killing my exits at low-speed turns!
I can’t handle those freaking Subarus! I drove one today, it has coil-overs, semi slicks, a very nice gearbox and almost 300hp. What a car, now I understand why everyone loves those freaking spaceships.
And my lovely VW let the bolts from the exhaust manifold get loose from the turbo! Just today! Track day! I’m half mad! Just because I ran over a 500hp Eclipse!

This is the Subaru that I drove.

Great stuff mate, when are you thinking of dropping in a Garrett and which one do you have your eye on? And please post your DYNO results when you get them

Any update on cams mate?

Yes.. sorry.. I was trying to test the car in the dyno before everything but they were full.
Ok my first impressions…
During my first runs I saw the fuel mixture at the peak power get lean but the ECU could correct it. But just for kill the curiosity I installed a 4bar FPR and I felt good results.
The engine revolutions are much faster, in the N/A phase before any boost I felt the engine stronger, and the turbo is charging faster and giving to the engine more power with the same boost.
The engine is growing well until the red line even with the turbo pressure dropping.
The temperature of the engine compartment is lower also.
I think with a k-16 turbo, or a garrett gt the engine will be great.
My conclusions, I felt a good gain of torque.
