i've never seen anything like that. thats gotta effect volume also cause there's more airspace there, that would normally be filled by rotor and can now be filled with air and fuel, thus increasing displacement. correct me if I;m wrong but doesn't that seem logical? also what about air/fuel getting compressed in those new pockets created on the side of the rotor. looks like those rotors would kill side seal life.

Those style rotors are setting records in EP Racing EVERY WEEKEND!

SSSSSHHHHHHH!

Pistons guys will scream at the board for rule changes!We get a leg up on by R&D and they will cut us.

i believe that would increase/decrease compression ratio, not displacement.





anyway, how much for a set of those balanced?

Balancing the rotating assembly runs ~ $500, The machine work on the Rotor cut is another $450. I am not sure what CLR is charging for the lightening: It appears that they have mapped out a very nice "cut" on a CNC Mill.

I keep emailing SDJ about getting my rotors lightened and never get a response

I'll be going to SDJ next week. I do know that Stan has limited computer access.

That's my rotor! Yes, done by CLR Motorsports...I'll have to pull out my price sheet to see what the charges were but they're not cheap. Well, well worth the money. Think bridge port without the wear issues. They're 88 Turbo II rotors which are lightened to 93+ spec weight (lightest weight spec'd by the factory). The scallops do not lower the compression ratio. The 88 Turbo II rotors have the thickest and most consistent faces. The 93+ rotors are crap. Very thin and they can melt easily, shown by dimples in the rotor face. Carlos built me one hell of a motor. I started with my Cosmo 2 rotor, tore it down and he went through it piece by piece. He built a no-holds-barred motor with all the bells and whistles, fully race prepped save for one mod to the crank which isn't necessary. Everything was "touched" and the list of engine mods is several pages long. The engine flows enough air for 600rwhp, just pick the appropriate sized turbo to achieve those numbers. I'll be "aiming" somewhat lower with a lowly GT4088. Should be capable of 20psi or a bit more on pump gas. Picked up my motor on Saturday night, had her "dressed" by Monday night and installed the engine today. Need to hook up all the fun stuff tomorrow morning but it should be running by sunset! Everything is clearanced so no real break-in is needed. Just keep it below 10psi til I get a feel for the engine and then it's off to tune! Can't tell you how excited I am to have a "real" motor. CLR's stuff makes engines from the usual suspects look like MANA motors :-) Need to start a new thread, "Carlos Lopez is building my engine!"

Forgot to mention, the rotors expose the intake ports for an additional 140 degrees of crank rotation. Pretty darn significant! Also, RENESIS rotors feature a small scallop on the rotors as well, not nearly as big, but they're there.

what about sideseal life?

that rotor looks great, but is it a drag-racing only thing?

how do the sideseals take the heat when it comes to long races like highway pulls and such?
