I wonder how much this part costs.... Star Race Cars Parts Catalog

 

Very interesting catalog; I wonder if ordinary mortals can order from it?

 

No clue... but it looks yummy.

you can upgrade your renesis with the front cover, pulley spacer, front plate, water pump, and sump tray .

I'm more interested in the water pump and if its upgraded or just modified to fit a bigger pulley for overdrive purposes.....

 

So is using the engine to brake bad for it since its not getting any fuel (premix)?

 

And their muffler must be good for +20 hp, right?

 

I looked at their water pump and was immediately curious if it was stock or not.

 

Yup..Timing Cover does not look S2 either..or S1

 

I'm not sure if its aftermarket but that pulley is larger than the ac compressor lol (sarcasm).

Yea its a custom cover with AN fittings for the sump setup.

 

I spotted the heat shield between the LIM and the header. I'd like to see how it attaches.

 

the water pump assembly is an 86-88 Rx7 unit. they are probably using that because the Rx8 has the water pump and front cover in one casting, and they are using the dry sump front cover which isn't

 

i get one if they can paint it in pink and cost 200 bux

 

This is awesome, thanks for sharing 9k.

 

odula japan has something like that years ago.

 

Got any pics of it installed?

 

Just get some sheet metal line it with reflective tape and strap it to the LIM.

 

they premix at 200/1?

 

I read the link OP provided. Thanks, OP.

I find this all interesting, but- and let me stress I'm pretty out of it today, so I may be missing the obvious- how do many of the maintenance procedures, techniques and intervals regarding this dedicated-race rotary have relevance and/or applicability to daily driven, garden variety, consumer owned RX8s?

 

Most of it doesn't have any direct application. Most of it is simply interesting.

There are a few bits that do apply still, since the engine itself is still pretty similar. Engine management and engine usage is different, as is cooling and lubrication. But there are still things we can use from it. Like the RPM limitations due to housing damage, the fact that Mazda still sees premixing as a good thing, etc...

 

You re wrong!

Mazda knows best we know nothing! 5w20 ftw! Premix is for idiots cuz omp.is more than enough ftw! Yada yada yada !!!!

 

Friend bought one overseas, dont have a pic now, will ask.if he can snap one for me. I think odula has it on its web site.

 

the dry sump oil system alone costs more than you are willing to drop on an engine

 

Amazing ain't it, the intake resonance works fantastically on a zero overlap engine but the exhaust with far more energy apparently does nothing

 

Never really seen any particular housing wear or even chatter marks on our racers, but then we make sure we inject plenty of fuel on the overrun (as much for side seal cooling and lubrication as housing wear too).

Don't get too hung up on the oil change times in that PDF, that's normal for pretty much any race vehicle.

 

Yup. I've never seen you mention it, though other racers have. I don't think either "side" is wrong, just something involved that isn't being shared/documented that makes the difference.

With the unknowns of the street engines, especially remans, a cautious approach to that is best in my opinion.

 

do they run pre mixed premix ( VP fuels has it available?)? I think they do.
On the exhaust--they have a nice flowing set up--but iit doesnt look like it is a "tuned". to me. But I know nothing really.
I am curious Philip--injecting at overun doesnt wash the lubrication away? Or do you have a high enought pre mix ratio to compensate for that?
