My engine is in the throes of being assembled (I know the Pyramids were built faseter than my engine) so I started looking at the manifold to see what needed to be done.
First comment is it fits on the engine nicely and doesn't need any machining to clear the front and back water bridges. I know some of the plastic covers won't fit anymore. The fuel rails all fit (one is a tight squeeze below my 90mm T/B).
I had to intall 4 additional hosetails for:
1. The Map sensor
2. The boost gauge
3. The Water/Meth controller
4. Fuel Pressure Regulator (FMU)
There was already a hose tail for the Supercharger by-pass valve.
I will need to install an additional hosetail after the T/B for the charcoal canister purge line and the vac line for the brakes.
After removing the top plate I was able to see how it lined up with the ports in the head and the general layout within.
First comment is not all the ports are perfect matches with the head. I need to do a little grinding, perhaps 0.5-1.00mm to make things perfect. I'm pretty happy with what I have.
Second thing is the outer ports look a little more restrictive than the inner 4. I know John Cribb had commented his outer cylinders ran richer then the inners. This would explain it. Again some judicious porting should improve that.
Third point is there is a sharp ridge right above the port which I feel will alter airflow leading into the port. Again out with the Dremel and smooth it off.
Fourth point is none of the ports have any "bellmouthing" to speak of. Again I'll round off the sharp corners to improve flow.
The attached photos show whah I mean.
All in all I like what I have and I didn't expect to recieve a "drop it on and drive off kit" as we all have different needs/desires from our engines.
Another point is most of us have had some porting done so the standard maniflod sizes may need enlarging anyway.
I feel the quality of the casting is good and the machining in general is neat.
The blower drive that I was supplied is beautifully made and looks great. I would be very surprised if it doens't work perfectly.
