Ported 4 port
Here are pics of Phil's 8' newly ported intake ports. Thats a mouthful.
So last night as some of you all know CRH and I went to a local Rotor Heads shop and I ported Phils intake and exhust ports . Ray and I are rebuilding Phils engine and thought we should give him some special treatment. Due to the fact that Phil is a wonderful guy. Well here are pics of the finished product,,, http://i59.photobucket.com/albums/g3...1082008013.jpg http://i59.photobucket.com/albums/g3...1082008012.jpg http://i59.photobucket.com/albums/g3...1082008011.jpg http://i59.photobucket.com/albums/g3...1082008010.jpg http://i59.photobucket.com/albums/g3...1082008009.jpg |
you handled that mouthfull pretty well :) lol
seriously though, looks good |
how much did you guys grind away?
|
Enough that we recycled the metal shavings and bought a case of beer.:lol:
|
Why the hanging top edge?
|
nice cant wait till its all done.
|
nicely done
|
good job guys
|
rico
|
nice job guys i'm curious to see it in the dyno! please post more info
|
any comments on how (much) timing/flow was affected VS stock 4 port (and 6 port)?
[off hand i can't remember the stock values...] always good to see things like this |
what kind of cutting\grinding tools did you use? i would like to do that kind of clean jobs on my engines as well!
Lucky Phil! |

Looking forward to results of your guys work! |
Well there is only one local shop on your side of town I would trust doing port work. So it had better have been Glen.
before and after shots? |

[off hand i can't remember the stock values...] always good to see things like this As far as timing goes, all that was done to change any value was adding a bit more duration to the port on the upper edge. There's not very much room for any other enlargement of the port. 90% of the changes were made to the interior of the port. Removing casting edges and smoothing out the flow through the port.

before and after shots? I was porting Rotaries in the late 70's. I think that was before Glen was born. :Eyecrazy: Ask me about it some time Dave. |

so a bit more duration on the intake? did you just alter timing on the secondaries? or the primaries too?
did you think you got close to the 80° closing of the auxiliary in the 6 port? I imagine he'll pick up a bit on the top end if I remember correctly how this works... (should increase the rev limiter~ ?) here's some reference info: |
There is no way to make the 80° port closing of the 4 port secondary compared to the 6 port. What I have done is add 3° +to the primary and about the same to the secondary closing point.
As I said the port walls are not capable of much enlargement. The most you could possibly obtain is 5° at the most. I would be worried about carving out the port to obtain that much. To get to the 80° point you would have to make a new rear and front cast iron plate. It just is not possible. Right now we are at the 48° 63° marks on secondary and primary respectively. I see no way to increase the exhaust port timing. Just change the exhaust port internal size and dimensions. |
i can haz ports?

Erick has been kind enough to port my 4 port. Don't know how to thank him other than to show my grattitude by posting my thanks.
Every little mod adds to the final outcome of the hp and torque. My desire has always been to have a 300hp 4 port. Erick has contributed to the final result. I can't wait to drive this BHR - Easy_E1 monster.:Eyecrazy: :Eyecrazy: |
Phil, I don't want any thing from you but MONEY! JK
I have always wanted to see what can be done to the 4 port and now I know. I was a little hesitant to go to any extremes but now I know what can be done. You will have a lot better flow and more intake duration. That should be a nice HP increase on your engine. |
thanks for the reply, actually that's what I expected you to say.
[judging from the pics, anyway] too cool. (and good job!) |

No it was not Glen, Dave. He's not the only one in Phoenix that ports Rotary Engines.
I was porting Rotaries in the late 70's. I think that was before Glen was born. :Eyecrazy: Ask me about it some time Dave. Any plans in the future to add a flow bench? |
very nice...we're all anxious to see this monster again for the first time :)

I called Phil yesterday at about 3:30pm Vegas time. I
told him he is now the proud father of a bouncing baby 8. Yes folks she is up and running. |
that's great news!
|
good to hear. can't wait for another vegas run
to see it zoom |
yeah, not sure if I can wait till the next Annual Tri-State Vegas meet to see this little beast in action.
We might just have to make a trip out there before that. |
lies.

The other day I was at Ray's and out of the corner of my eye I thought I saw something. I was really thinking it was the elusive Michelle. :uhh: |
