Sevenstock 8 was awesome!
RG, bummer I didn't get to meet you but hope you had fun on your trip out to Cali.
I took 100 pics today...I'll post them later on.

Cool! Thanks for posting those great pics guys. Any new rumors or actual real news to report with regards to the development of the Rotary or RX-8?
And what happen to that one-off prototype supercharged Mazdaspeed 8 that was on display at MNAO HQ?

guys, that new engine is a 6 port, not a 4 port. We had to look twice ourselves. They changed the upper intake manifold and there are 2 more ports there. It's just not the same as our current 8 manifold.
EDIT: and btw, brillo posted all those pictures, not me. I have some better pics of that manifold so you can see it.

Brillo was logged on to my PC so he posted as me.
I've got 225 pictures to post eventually as well as a video of the 792.

I have the final definitive word from both Mazda and Rick Engman on the use of synthetic oils in the rotary. the Mazda guy I asked has been the head in charge of rotary development since 1974 so there was no one higher or better to ask. Rick Engman is the engine builder for Jim Downing btw and is probably the foremost expert in this country when it comes to rotaries. Just to tease everyone with the answer, let's just say if you know what my position is, I have a really really big smile on my face! :D I'll get into more details later.

One hell of a happen-in. Worthy of the "stock" implication.
I met so many people from so far away it was amazing.
Hell with the Mazdas, I love those 1/3 scale engines that guy builds.
He says some day he'll do a rotary. Can't get over the fact that he does all that on an old Southbend lathe and a Bridgport??????????
Anybody know how many cars and people were there?
I didn't get the chance to spend the time I would have liked with alot of new freinds and look at more things but I had some domestic problems going on.
I have a 90 year old mother who lives with me and this was a bad weekend for her. She doesn't understand when I can't be there and panics. Not all the time just some. Maybe most.
I really loved the chance to talk tech with a lot of you without having type and miss spell.
The most comment I had was "it's so small." Except from Turbine_pwr he knew it would be.
Now if I were to build one of those 1/3 scale engines would I build a 1/3 scale axial flow? :D

Ok here's the official scoop on the oil issue. As I said earlier, I asked the highest people on the planet when it comes to rotaries. First I'll start with Rick Engman's position as he built all of the engine's for Downing. I looked at Rick and just quite simply said, "synthetic oils". His response was, "I wouldn't use anything but synthetic oil in a rotary". Thankyou Mr. Engman! All of Downing's race cars use Valvoline synthetic. He said it doesn't matter if it is a race engine or not. I also told Mr. Engman that many people say you only use synthetics in a rotary because it gets rebult all the time and that it doesn't matter what happens to these engines. I can't post what his opinion are of these people! He did say their engines get 100 RACE hours of use between rebuilds. The Courage is using experimental engine parts that were last used in the 80's and 90's! They care more about the longevity of the engine on a race car than a street car so some people's logic is VERY flawwed.
Now onto Mazda's position on synthetics since I know that the opinion of the smartest rotary person in the U.S. isn't good enough for some people. As I stated earlier, I asked the head of rotary engine development for the past 30 years at Mazda. He designed and built the 787B engine too. In very broken english he told me that not all synthetics are created equal. some are better than others when it comes to mixing with fuel in the oil metering system. The oil metering system is the key. It is NOT with swelling seals. He said that because some oils work very well and others not as well, it is far easier to just officially say not to use them than to say which ones to use and not to. This has actually been speculated for a long time and now we know it's true. I asked which synthetic oils he does not like. the answer is very surprising. The worst synthetic oil for the rotary according to the smartest rotary engine person in the world is Mobil 1. At least Valvoline and Royal Purple are fine. Didn't get any others listed. Rick Engman did say that decades ago there was an issue with some swelling of seals with old synthetic formulations but these have long since been resolved.
To all the people who keep getting on my case and others for using Royal Purple, WE'VE BEEN THE CORRECT ONE'S!!!!!!!!!!!!!!!!!!!! :D
Yes you can switch back and forth between oil's if you absolutely have to.

[QUOTE=Toadman]Here's a few re-sized ones. Ajax likely has the good pics(supercharger?). We'll start a SS8 pic thread and move these there. I felt compelled to beat Ajax to the punch, being local and all. 
Lots of scissor-doors this year for some reason.
Toad man, you so crazy! :D there was only 4 cars there with Lambo doors. 4 out of 400, thats not very many at all. he he he that means there were 396 with normal doors. :p
