I will add a change light and some
instruments to read engine conditions.
The change light is a HiTech design
that should resist moisture and vibrations equipped with LED bulb ,-) Hope
the lamp works in bright sunshine.
Here is the new EGT gauge and IAT gauge
from Mainline Sensors at eBay.uk.com shops. The EGT meter reads up to
2300*F(1250*C). I have an IAT meter already in the system but I can the
only read it from the laptop display.

The battery is going in the boot in the spare wheel well. This lighter
bettery will take 30 lbs (13 kg) off the front axle and add 20 lbs (9 kg)
to the rear axle.

The water tank for the cooler and the battery have found their final
position and the water pump and the valve for letting the water out
almost. The heat exchanger for the cooler is not coming, the water will be
changed when it gets too warm.

This is the summer 2015 version of my engine compartment with the air to
water intercooler, supercharger and turbocharger and a bypass valve
between them. The bypass valve opens at 0.7 bar (10 psi) and the
supercharger poes off at the same time. I'm still testing fof the best
change point. The air cleaner is down behind the air dam.Now I only need
to get the car to run!

I have been studying the differences in engines 111.944 (the former) and
M111.975 (the present). This is the M111.944 cylinder head on the exhaust
cam side. You can see that the exhaust cams are not identical - the one on
the right has a fuller form and opens the valve earlier. The closing
sides of the cam look about the same. Is this feature for swirl or what?

The lifts of the intake cams are about 0.37" and 0.37" (9.3 / 9.3 mm) and
the lifts of the exhaust cams are about 0.37" and 0.33" (9.4 / 8.4 mm).

The newer intake cam (VVT) seems to fit in the older cylinder head. The
cam has the same lift as the older one but the duration is about 10
degrees longer. I found a pair of the older cam sprockets which are better
for adjustable gear setup. PO-Metal machined larger adjustment holes (+-
10degrees on camshaft and +-20 degrees on crankshaft) in the sprockets.

The VVT cam has two oil holes which have to be closed. I made M5 threads
and screwed M5 screws with loctite and cut them along the flange surface.
I must move the cam sensor finger from the old sprocket to the adjustable
one.

I had to modify the timing cover in order to make the coming changes in
cam timing easier (e.g. not needing to let the cooling water out). I
believe the valve cover still needs to be taken off to remove the upper
part of the timing cover. The plan to keep the oil inside the engine is
still on the drawing board ,-)
