John most after market coolers cant take the oil flow of a rotary and blow apart have seen this many times . I prefer to use original mazda ones . I would use 2 cosmo oil coolers [Off the 20b ] they are strong and more compact than the other mazda coolers

John......most of RX-8 we rebuild are run by customers till the very end, destroying bearings completely and when you remove oil pan, you do not get big pieces but rather something like copper paste :

A ~quick~ search revealed a gentleman who claims an engineering background yet absolves any expertise on subject matter and allows the reader to draw their own conclusions from his research. He details many filters and the efficiency or their micron "ratings", anyways, interesting read http://www.gwrra-ohh2.org/pdf/oilfilter.pdf And another TSB from Amsoil in 2007 http://www.amsoil.com/techservicesbu...ine%20wear.pdf Thanks for learning me something higgi EDIT: This information also appears to be from what I can tell as 2003?? So things may have changed. Also sorry for Hijacking |
I wonder if you really need that much oil pressure.
I suppose you choose the position of the oil injection point into the bearings in conjunction with the "big bang point" of the individual rotors to create a high pressure wave in the film? I hope you know what i mean.😱 Better go for high volume, rather than high pressure (there is a difference). Besides at high pressure you may have problems with "choked flow" as oil has a relatively high viscosity when cold. Just a thought. Grtz Dennis. |

....Yeah me too! Might be a while though, replacing the igniters is a quick job, but fixing the oiling issue might take a while. Also don't have a lot of time to work on it in the next month :(

11 days and no updates, did most of you go on vacation?
|
Yep, I'm in greece at the moment. Oil coolers and ignition modules are waiting for me back home, so can't wait to get back and get it running!

Man that is awesome. Ain't nothing like having your own CNC and the skill also save some coin on making your own e-shaft. Damn I need to get a CNC. What program are you running autocad or soild works. That dose not look like bobcad lol.
|
John doesn't have any CNC :)
But he uses Solidworks. |
Yeah, no CNC for John here. He's doing it all the old-fashioned way (besides using Solidworks).
|
soooo, vroom vroom?
|
bumpity for updatey
|
Please do not bump this thread, John will update when he has news ;)
|
Yep I will!
Been in the US for work, didn't bring my car with me so I haven't been able to work on it lately! I'm going home soon, and when I get anything done I will update this ;-) |
BIG NEWS EVERYBODY :)
sorry John |
:drool::drool:

Fixed the oil coolers, there is a set of RX-8 coolers in there now, had to hack up the aluminium vents a bit, add some brackets and change the oil lines but now it fits and works. Also replaced the cheap ignition modules with real bosch ones. The cheap ones were wierd, they would fire the coil, but some of the plugs weren't sparking as strong as others. Swapped the modules and it's fixed. So spend some more time messing with the ecu and now it actually runs and idles :nod:, here is a vid of it:
Still messing with it, the ignition timing is off, it's way retarded and changing the trigger settings doesn't seem to do a lot. the AFR values are way off aswell, it reads about 1:10 - 1:11 at idle, and if I start to lean it out the engine dies. The AFR is probably off because of all the misfiring, but that usually causes the meter to read lean, not rich. No major troubles though, so I'm happy :). |
Zounds!
|
Lol John same vid in a few minutes, btw no Dauwtrappen?
|
:mspank:
|
Incredible work! That sound is something else!!
|
Yesssssss!
|
Amazing. Simply amazing
|
Worth the wait. That is really cool. Congrats on the start.
|
Almost brings tears to my eyes.... Been waiting a long time to hear this. It sounds amazing. Top notch work every step of the way.:D
