Status Report 2007

It was a hard fight to get this thing together but I finally made it in August.
The main problem was of course lack of free time. I've got 3 kids and a ridiculously high workload on my current assignment... Putting the engine together went smooth but then the turbos wouldn't fit between the frame in the engine bay. I had to cut the turbo flanges from the exhaust manifolds and turn them a bit. Moving a turbo involves moving all the connections to it so it took a while. I bought a welding machine and welded the exhaust myself. The turbo pressure side plumbing had to be made to fit as well.

I removed the engine by placing it on jack stands and lifting up the car.

I used a pallet lifter to lift the engine.

Here is the engine block with 90mm pistons and the heads with Ferrera valves.

Bottom of the engine assembled using Clevite bearings and ARP studs.

Next picture shows the JWT wild cams that caused me a lot of head ache. The engine would not start even though it had the fuel, spark and appeared to have the right timing...NOT! The timing was 180 degrees wrong due to the CAS aligning axle being mounted 180 degrees wrong in the cam!

The KU-engineering manifold was beautiful to look at but it needed quite a lot of treatment to make it fit.

The holes would not align with the studs. I also had to widen the inlet holes to match the ported heads. Apart from that, I was forced to cut away the turbo flanges to make the turbos fit in the engine bay.

Since the engine power was to be substantially higher, I replaced the flex plate with a stronger one. I also used the Border injector kit with Sard 850cc injectors.

I run in the engine during August without any problems, apart from a slight oil leak. I suspect that the oil is sipping out from the main oil gallery between the head and the block though... I may have to remove one head and replace the head gasket.
I didn't have the time to map the engine properly yet (running to rich now on a safe map). I also noticed that the turbo pressure is not stable with quite an overshoot at the beginning and to low pressure after that. I will be replacing my Apexi AVC-R with a better regulator. I planned on developing one myself but looked at it realistically and came to the obvious conclusion that I will not have the free time to do it.

I managed to attend on only one track meeting this year and I'm quite pleased with the results. I made a 12.0 on 1/4 mile and 1:29:18 on the Swedish standard track Bilsport Superstage. The Superstage track is used to compare all kinds of sports cars in Sweden and has become a performance measuring tool here.

That's it for now. I suppose that I won't have the time to update the status pages until next Christmas holiday...
Enjoy the ride!
