New Rotor technology

As far as the other questions I will let him answer. I think the weight is down to around 7lbs last I heard.

That fin is actually a old trick in order to hit the beam first at the end of the 1,350 ft without using your wheels , as downforce is created at top end the front end becomes low and that fin hits the beam .... Ugly but Efective .

Actually when Brent Rau is racing the ADRL series, he has one of those fins on this front bumper. I believe it depends on the position of the beam, which can vary between tracks. This is my assumption

Maximun overhang permited by NHRA is 45 inches, measure from the center of the front wheel to the tip of the fron end of the car. In some bodies like the R-100 without the fin we have only 18 inches of overhang, thats is going to put us in disadvantage with other races runing 45 inches. Thats why we put this fin to compensate for the short front end and have the same advantage. Remember we stage the car with the front tires and trip the beams with the front end. www.pmsracecars.com

Also, with this in mind, I have seen several starlets in PR running 7.0's without any fins and wondering if they had they may have run a 6.9 pass?

At those speeds, you're looking at less than a hundredth of a second.

Last Friday Edgar from E&J invited us for a tour of his shop and to see the billet rotors in person.. I was expecting them to be lighter than a Rx8 rotor, but I was blown away when I actually held it in my hands. I couldn't believe it, so I went searching for a Rx8 rotor for a comparison
Edgar is a very smart guy. He opened up to us about his R&D and his reasons for taking on such a monumental task. These rotors wasn't concieved out of a plot to get rich. Edgar spent time working with various engineers on this project because he wanted to make a positive difference in our little engine.. Without letting the cat out of the bag, these rotors are the envy of various big companies and quite a few would like to put their name on it. There are quite a few tricks that set these rotors apart from an OEM unit, so don't think it's only about saving weight. Take a trip down to E&J and Edgar will fill you in
I have faith in this product and It's only a matter of time before my Rx3 engine get a set of billets
I would like to thank Edgar, Alex and everyone else that gave us the "behind the scene" tour of the various projects, parts and "top secret" info

^ Yea I hear you.. I wish I had a better background
Dude, pics don't do justice to these rotors, you have to feel them in your hands..Its pure sex!!
It's not an exact copy of the mazda rotor. The engineers figured since they were starting from scratch, why not improve it's design instead of just making a lighter "copy"
I will not eleborate, I want you guys to go see it for yourselves and speak to Edgar in person.
Anthony where are your pics??

It looks like they might of make it a few Thousands smaller in diameter to compensate for rotor growth and width....
The secret might be in the expansion of the rotor,heat ,distortion and wear.The apex,side seal and corner seal slot might be opposite,
larger in clearance so the won't stick and you get even wear,this i came up with in my head right now as we speak......interesting.
I see the large holes in the center where the stationary sit.....looks like the oil flows through there to lube the other side of the rotor...
compared to the stock rotor,the oil flows through the inside of the pockets for cooling.I was kinda of puzzled how the oil was going to
flow to both sides of the aluminum rotor but now i got it.

Found out this about Mazda alum rotors. States the book/magazine it was written in. This is a response from someone mentioning it a bunch of posts back.
Pic of engine not that you cant really tell that the rotors are aluminum. They do however dont look"normal".

Billet rotors
We just want to take this time to let every one know that we are hard at work and doing all kinds of testing. We are also happy to announce that our new distributors over the Uk "RotaryArt" have 2 set of rotors in stock for any one in the are to go and check them out.
We also want to let every know that Carlos Lopez from CLR is working with us and doing all of our balancing. He will be bringing some knowledge from the road racing world and offer us some ideas to bring you the consumer the best product available.
In the next few week we will be doing some more testing on a Nitrous set up. We hope to break into the 7's with a two rotor. This would be a first. Stay tuned for the latest new.
thank you for all the support.
