Why don't people port 6 ports?

aaron,

Maybe you are thinking the older versions or maybe the wolf3d site is fibbing? Or maybe I am just plain wrong. But it says

Under general specification:
1,2,3,4,5,6,8,10,12,16 Cylinder operation, 1,2,3,4 rotor operation, odd cylinder and odd fire supported.

Then under IGNITION DELIVERY AND CONTROL SYSTEM:
Rotary Engine Leading/Trailing drive method selectable

Also I had a friend here in Pullman that used to have the older wolf on his second gen and he says he loved it.....

To me that makes me think that it is made to work on a 13b as well? I may be confused....

The last version I worked on (version 4?) could not run the trailing toggle so it was not possible to run stock trailing ignitors. Had to get another two leading ignitors, swap the trailing coil onto them, and run them using two ignition outputs. Not entirely ideal...

I'm also not big on the software as it crashes and is often unnecessarily confusing.

this is just the middle section gone..... no other porting on the sides.

that's how my ports look. the car performs well a lil slow til bout 4 1/2 bout once its there is pulls til 9 1/2. if i balance the motor then 11 is just as easy.

IMO (1st hand experience), I (partially) disagree with "rotarygod" and some others out there. I find that people often say things will not work or can’t work in spite of the fact that they never tried it for themselves.

“If you aren’t testing your guessing”….

Back when I was in college 96-00. I had a “STREET” driven 85 GSL with a half bridge in the aux ports and it ran GREAT well over 200rwhp. I had a side draft Dellorto 48mm carb before I went with a Holley 550 vacuum secondary carb yielding 20- 23mpg (like any rotary one good pull and a week of good right foot behavior was out the exhaust).

Why run a half-bridge: well there are two ways to make power add displacement (turbo) or rpm (rotaries lend them selves to rpm anyway). At the time it was much cheaper to do the latter of the two and it gave me the performance I wanted out of an NA platform while remaining streetable.

My car would accelerate hard right off the line but at about 5,000 rpm the car would pull almost exponentially (it felt like a turbo coming online pushing you back in the seat) this would carry you thru 9,000 rpm. People say what they want but 5,000 rpm in a well tuned rotary passes in a blink of the eye.

For turbo application Bridges and half Bridges, work but I too believe that bigger is not always better; Although bridges ports are said to work best with no exhaust restriction (Turbo) there are plenty of guys that will tell you Bridges work fine on turbo apps. One thing I can defiantly say is bridge or no bridge I would not run the sleeve on a turbo app.

For my application I removed the sleeves, all emissions, and ran a free flow exhaust.

13b 88 block 9.4 /11lb rotors
Half-Bridge in secondary ports
RB Holley 550 cfm vacuum secondary carb
Jay-Tech 6-port Manifold
RB 17lbs Flywheel
RB Road Race Exhaust (to 3 inch over diff to a Borla 1 in 2 out muffler, RB way to restrictive)
RB pulleys (water & alt)
Dual electric fans
MSD coils
RB wires
15’ deep dish panna sport rims
Full suspension (bushings, sways….)

Rotarygod to say that if people ran smaller ports we would see faster cars is a partial truth and miss leading. You would have to specify where the cars would be faster, porting makes for faster cars upstairs and gives the engine more potential power. I guarantee Racing Beat land Speed cars were not on stock ports. So the question is: Faster where???
