Awesome to hear the results.

 

Just wondering of you guys are planning on testing these rotors in an all motor N/A car, preferably a pport motor? We are hurting in this department against the Honda guys and I think these rotors would help out alot in this matter.

 

We haven't tested on a n/a application not because they wont work. We just don't have any data to back our information. On our turbo car we were able to increase our horsepower by 80 horses at the same RPMS and very conservative with our fuel and timing.
For our road race test, we will have a N/A PP set up and we hope to increase our RPMS to 12000+ and a horse power increase of 75 to 150 hp from there original set up.

 

Are the set used in the street testing going back in for more?

I assume you're using a different set for each type of testing. . .

 

The combustion chamber is obviously a much different shape than the Mazda rotors. Is this what you attribute much of the power gain to? Since you're making more power at the same rev you're increasing torque at that rev which means something's gotten more efficient in how the engine produces power. Since you haven't changed porting you have to be doing more with the same amount of air. Or am I way off?

 

well at this time we have two working sets. the set that we have on the red car have never been change. the one that we put in the street car are the second set and the original. this were the one that were on the motor that was on the floor. we have a video on you tube.

 

Well is more than that. Is the combination of the chamber, the weight and a few more thing that were done to the rotors. With our rotor the power come in much faster than before.

 

congrats on everything!!! things are looking great!! keep up the good work, i hope to one day own the final product and rip it down the highway at 12k rpm!!! lol

 

One past says the 505 rwhp was made at 17, one says at 18... which was it? Also, what sort of gain was realized over the previous setup using these rotors, if there was a test done...

 

I'm assuming the test engine didn't change and just had stock rotor's beforehand.
Do you mind telling us what power increase was archived with just the rotor change ??

Edit: opps didnt read the post above.

Was their any results you got, that you had not expected ? eg more torque ?

 

Guys I bet you the majority of the power increase with these rotors is attributed to the furthure lightening the rotating assembly. Since it now takes less energy to spin the rotors and e-shaft, more energy/power gets to the ground. Hmmm then again if that where the case, you would also see big increses with light weight flywheels. Damn now I'm confused!

 

Just guessing but the shape of the combustion chamber looks like it would concentrate the compression in a smaller area and maybe provide more drive when fireing occurs.

 

the funny thing is alot of this was explained within the 15 pages of this thread, rather in depth too

 

The finish on the rotors surface looks like it is unfinished as if it were just pulled form the cnc and put in the engine enabling the carbon deposits to easily take root. I imagine giving the rotor surfaces a good mirror polish would inhibit carbon buildup to the degree as pictured so early. I'd also suspect that it might be necessary to give them a polish (or other surface treatment???) considering the malleability of aluminum vs. steel and the susceptibility of the aluminum to incur damage from too much carbon buildup.

 

Flywheels don't produce power!

 

Sure you do see flywheel HP ... it free's up more power to wheel, on a mustang dyno i've seen about 10 whp ... had to retune things too becauses it was easier to rev up the engine.

 

oh god, not another flywheel hp debate. Stick to the rotors for the love of god

 

Think you can draw? Send us your best drawings of our new BILLET ROTOR and the winner will be featured on our new stickers.

good luck and thank you

great news with the road testing there

any videos of this street gt47 car in testing?

 

But it can make you faster!!

 

So can liposuction and dropping 50 lbs, but that has nothing to do with power output! :P

 

A flywheel should be looked at not from the standpoint of a power adder but rather as a contributing factor in drivetrain loss. The weight of the flywheel (and where the weight is on the flywheel) will determine how much power it robs from getting to the wheels. Some rob more power than others.

 

Of course. I think the question earlier was however why is it that the same percentage of weight loss taken off rotors (which are also part of the rotating assembly) give a much more considerable increase in power than a similarly reduced weight from a flywheel. And the reasons are I suppose because of the leverage effect of rotors on combustion, the direct effect from combustion, the multiplication of leverage to E-shaft, etc.

 

I never said it did bud.......

 

Have someone put the rotors in a light box and take some better quality pics.. use a black background and get pics from different angles
