Wasn't just the F 1 guys,

This stuff, apparently is required for (WMD)'s : Weaponds of MASS Destruction.

WOW !

The Italians have a big problem.

sounds like a bridge port with NO BRIDGE!
ohhh my god give us a video please!!!!!!!!!!!!

also,how much power is he expecting to make?

Been there done that a few times..
The Sad face indicated that I wasnt "Dissing" just sad that I missed out on calling while all my questions were fresh in my mind. I was also starting a 13+ hour shift.. Bleh.
As its 6:45.. I think I will wait till I get up in 6 hours to go to work again.. and call after I get things settled at work.. and can think clearly..

(BTW... will be asking about N/A rotors for a EP application.. /grin)

Very neat stuff. Kudos. This isint ITA legal though is it? Would this be compatable with streetporting as far as IO? Sorry Im always full of questions when I see something interesting and creative.

i want to know what combo of porting and these rotors would be the best for a daily driven high hp motor. Im guessing you could just run a set of the rotors in stock port housings and get large gains for many reasons.

But like i said... what porting to the housings would be a good combo for these rotors? Im thinking a street port? maybe?

Also i think i will be calling for a set of these rotors when i build my next motor. have any used ones for sale?

Although I'd "like" to say: "Yes this will give huge gains in performance, and add all sorts power, !!!.. The FACT is: The increases gained by the scalops should be considereed as an "ADD-ON" to Intake PORTING..

Porting is the PRIMARY means of increasing performance and VE.
The Scalops (Rotor Port phazing) will add "time" to the maximum port timing & overlap provided by proper PORTING., Thereby increasing the breathing cycle's time by "X" amount in degrees of shaft rotation, . In fact, ths Scalops" in them selves increases breathing time, & add to the Volumetric Efficiency of the engine, but are best used when combined with some form of Intake side porting.
Unless, otherwise when used in some type of spec. racing, in which NO form of PORTING is allowed. .
The top National Mazda EP racers are known to have "experimented" with this type of technology. (never to say any have ever used it ) !!

Bottom line, ... big gains can be made, but bigger gains have been "documented", when applyed properly.

would a half bridgeport be a proper port to have sick gains? or would they almost "interfere" with each other? <--if that is possible?

Are the scalops the same size for secondary and primary ports? (if ports differ in size)


I edited the pic of a primary port, to represent the secondary of a HBP...red = bridge, blue = scalop

How do these rotors effect cumbustion chamber efficency? Have you had to run more timing advance to account for longer more erradic flame front? At the peak where the scallop meets the dish in the rotor and where the scallop narrows by the side seal looks like possible hot spots? Have you had any pre ignition due to this? Im very interested in your product just want to have the facts.

BTW, not that I care because Im an Autronic guy and it one of the fastest systems availible but at 7000rpm's an 8bit prossesor can receive all information from the engine sensors make its calculations from all its base and modifier maps and output signals to the coils and fuel injectors about 40 times during half a degree of engine rotation. Seems fast enough to me for just about anyone on here. Unless you're into street bikes!

Is it possible to have too much port timing? If you had a bridge with notched rotor housings, I'm assuming there has to be a point of diminishing returns. How well would the scalloped rotors work in this example?
