Mods can include: Oil passage mods to front and rear flat housings,oil mods to stationary gears, polished eccentric shaft, eccentric oil jet installation, bearing pre-break in (Lapping), front cover oil and water mods, shimming of primary oil pressure reg, installation of our Ceramic seals and our water pump. Some port work is sometimes an option also.

Off topic, how likely is it to increase the compression of a RENESIS to 11:1 for use with E85, without resorting to the extreme rebuilds. (ECU reprogramming would be required, of course)
Can the recession (air pocket) on the rotor can be shaped to have deeper on bottom and shallow on top? I'm assuming it would help with the rotation when the combustion occurs.

It takes finding the right pre-heat temp, the most compatable weld filler material composition, a controlled cooling and maybe it can be done without warping things too much. Anywhere the weld filler is added will create shrinkage across that surface. It would take a post welding stress relief to somewhere between 900° and 1100°. That in tself will probably leave some distortion. Finally the weld filler would need to be machined and the rotor would need balancing.
Lets go back to the difference in the rotary vrs a piston engine. A piston engine has a more spherical shape which is closer to the ideal to minimize detonation. A rotary has a rectangular shape resulting in compromizing the optimal pressure-temperature peak.
Higher compression would work better for a piston motor. I would suspect just advancing the timing would be just as effective in the Renesis. It might be a good subject for a seperate discussion and even better if one of the tuners wanted to play around with it.

So a Rotor is welded from three pieces? I had the idea that it would be forged.
On topic. Is there anyway the rebuild of a RENESIS can increase raise power without resorting to forced induction?

They're at $2500 plus core presently and can cost as much as $6500 as tricked as they can come.
We're going to try to keep the cost here for as long as we can which is a interesting process in itself. We won't ever use the crappy parts that some builders would consider and there are procedures that we employ that some builders have never even seen.
The main reason that we sell cheaper than anyone else (For the quality) is partially due to Rick's free labor at the moment. He, as owner/builder has been kind enough to make this donation at this time. We're finding cores with less re-usable parts and simply absorbing the cost of providing a greater amount of new parts continually.This is done as a service to the RX8Club community. We'll see what happens
