Polish doesn’t really flow with your theme (IMO)
Just be sure to have it lightly polished if you powder coat it... otherwise the rough cast will show specs...

I'll await more reviews/tests/dyno's of that setup before I speak anymore regarding performance.
It definately looks awesome though

I should make it to the dyno next week hopefully.
Just thought I'd share some of the comments my tech shared with me regarding the cos install:
"Just wanted to give you low down on your last visit. Everything went well with your intake install. I managed to retain the thermal barrier for the throttle housing and used the new Hondata gasket. A few things needed relocating but overall it's a great fit. I used my inch pound torque wrench to torque the bolts holding the carbon end caps on as specified which is only about the third time I've used that overpriced tool!! I had a bit of an issue getting the ecu to relearn the idle air volumn value but eventually I got it. It's very specific as to the rpm range and load it will relearn the volumn of air entering the engine at idle. With all the changes to rotating mass and air flow on the intake side it's not surprising.
Your oil separator was full so I removed and emptied it. It seemed to be a mixture of oil vapor and water which is exactly what would be expected. Your oil level was fine, no worries there.
The pulleys all were tight but I did reset the belt tension. I did hear some noise from the belts and I think it's due to the fact that the pulleys are aluminum and the belts will pick up a glaze of alumimum as they wear. Aluminum is soft and will easily transfer a surface glaze. I don't think there is much that can be done. Your front crank seal was totally dry, no leaks. I made a template for your heat shield and will make it over the next week or two."

Let me just say that the MD setup made more power overall, with a slight twist...

Interesting... I'm anxious to know what the "twist" is... I imagine a tune would be in order for proper a/f with this setup - seems that flow velocity would be greater?
