Installing a new Canton pan - Do I still need the windage tray???

[Bernica]

Yup, you filled the floors. Nice! You should stuff a tennis ball in one so folks can see just how big those ports are!

Gained 40 cfm and reduced CSA as well.....

Bylkins Nice port job, can drop a tennis ball in that hole. Now show and tell about the dark side, You know the one with the deflector. We both know that's the bottle neck on these combos.
Would like to see a flow video of how bad air turbulents is on the back side of the deflector. He both know air doesn't like to bent. Also know the faster the air flow the more turbulent is close to the valves in the head.
See we both like a layed down "D" port. I did have ideas about if small ribbing in the port would help deflect the air better behind the pushrod deflector. The Idea of smooth porting and polishing against rough CNC grooves left in the ports. I know on the floor where there is dead air catching fuel droplets is a plus and fuel heats and goes back to a gasous form and is sucked in on the next valve operation.
Last Note, Is there a way to FI this motor with a dry intake manifold. More cfms, air is lighter than combo with fuel. More flow should be the final outcome. Direct injection would be the real winner. Back to work. Thanks for the snow and 5+ degrees. going to get up to 22f+.
Cost too much but cammer head motor is the way to go. Little work on the short radius and that's it. Hey, have a good day. Rick l. Ps would you be going to Goodwood cruise in Aug??

I can't take credit for it, Lawes Mayfield did the port work. There are a few bottlenecks in a TP port...the sheer size of it can be one. The pushrod tubes going down through the intake ports can be another. These don't have many bottlenecks now though....

A tidbit of info is that a smooth port isn't always a good thing. A rough CNC finish or even dimples in the port can work wonders. Think of a golf ball... Sometimes it makes more horsepower, sometimes it doesn't make more horsepower, but makes the engine more efficient, to the point where you can pull fuel out to hit the A/F ratio target.

Got up this morning and it's 1 degree here. Global warming?

Brent ... since this thread has already drifted .... go to Speedtalk and look up the thread "Why an engine makes more power off a burr finish" .... all 58 pages , back on 11/20/14 . Lots of good info , photos and hard test data .
Makes for good reading when it`s 1 degree out there .... 17 here in SC .
