So that water to air intercooler on Scott's setup provides shorter air path for incoming charge?
MazdaManiac tried to convince me it was more efficient than air to air cooling but I couldn't see that (not that I completly grasped what Maniac was saying at the time, nor am fully schooled in turbos, but I have played with PC CPU cooling) and some of the principles have to be the same. The water cannot be cooler than the ambient air and I live in AZ). CO2 spray may help (as Mr Maniac pointed out).
But in the photos I do see a shorter air path from the turbo to the engine? Maybe chopping about four feet (or more) out of the compressed air path reduces lag?
And damn I missed the Mazsport booth somehow. They were nice enough to put a flyer under my wiper. I need to be more methodical when walking through those vendor booths. All the shiney parts and cars distract me.
Looks promising. I may be willing to sacrifice some home equity on one of those kits if I can get 350 whp and pass emissions on the 8. I know I am greedy, but I can ask!
Thanks for the photos.

I hope the Renesis can hold up to the high horsepowers. But its basically the same as the FD, probably stronger housing and rotors too.

but think about it, its like saying the greddy is 5k+. You have to have 5k+ to make the thing max out at 300whp with interceptor and goodies. This 8-10k pricing already has that extra stuff included in the price. From what i can tell you wont need anything but this kit out of the box to run well, except maybe a new clutch.

I'd agree with you. Upgrade clutch/flywheel/pressure plate.

They aren't working on one right now but it doesn't mean they still won't pursue it again someday. The one thing we did get from this weekend was that the rotary has a long future ahead of it.
I really expected some whispers about DI as the next generation, or a capacity change to the RENESIS...

Carlos Lopez is the MAN! its funny because to me he's Famous. others even in the rotary community dont know his name. i was telling a couple of younger guys who everyone was at Racing Beat and i said in front of Carlos' wife "thats Carlos Lopez he's kinda famous" and she rightly got some digs in about my comment- i didnt mean it that way of course- i was trying to explain how some people may not have heard of him but should. But he is a hell of a nice guy who took my backhanded compliment quite well. and He has huge amounts of knowledge and experience and the ability to share it in a way anyone can understand. trailing first ignition timing (negative split- like the renesis does at idle) always while in vacuum. nearly direct injection in a peripheral port 13b( i say nearly because its not exactly like you think of direct injection as its being used in some production cars now) and even how to induce some overlap for better exhaust tuning and power gains in a Renesis.(cant tell you how thats a trade secret
) in fact i maybe shouldnt mention that and will probably edit it out later.

Carlos said for complete true independant spark timing he would run what ever EMS he was using and let that control leading and then he'd run a megasquirt to just control trailing. so one wouldnt be indexed against the other. it wasnt trilin g15 degrees after the leading firing. it was leading when it was best to fire it for power and safety and trailing when it was best to fire it. trailing first in vacuum (he does this to get as close to 3 plug firing as he can with only 2 plugs) leading in boost. whats interesting is thats exactly how Mazda runs the firing in the Renesis- the leading and trailing are fired completly independant of each other for best power, fuel efficiency and emissions. Carlos has been doing it longer then there has been an rx-8

Go Texas Longhorns!
Well, its been a long but fun weekend, I’ve had some time to reflect on the weekend and what we learned as I get ready to leave the left coast.
First off, the new event location was great, a lot more room (even though we could use the whole Ford Premier Group parking lot) Great attendance, 500+ cars and a lot of vendors showed up. Bernie and the Socal club guys did an amazing job again with the organization and planning, how the hell you can get that many cars into a area so quickly in an organized manor is beyond me.
My overall take away from the event was that there is a lot of rotary support from Mazda and the race teams down to the individuals who flew in from as far away as Japan, Australia, and Europe. I got the feeling that most of the higher ups do realize that the rotary will continue to face an uphill battle to remain relevant in the future as a competitive engine. I think the passion so see in the company from the past is still evident, and I’m sure there are folks tooling away in Japan working on the next iteration of the engine.
We keep hearing about hydrogen, but I think that is really Mazda’s version of e85. It’s a cheap dual fuel modification that also happens to be green and makes for good media, but isn’t really that practical due to its storage issues and efficiency. DI is the future, and the more I asked about it, the more I got Carlos Lopez, Rick Engman, Kobe and others to open up about it. A lot of folks are looking into DI and making it practical, which will be necessary for the next engine.
We of course couldn’t get any info on the MS8 or any form of turbo/super charged version. We saw all the parts at racing beat from Mazda’s testing over the last two years. In fact, none of the parts had really moved from last year, I prolly could have taken the S/C home with me if I wanted too….it had dust on it. No hidden cars or mules were found, the half painted mazda6 was about as exciting as the test cars got. We heard at the banquet about something being announced at the Sema show, but the gentleman speaking was struggling with English, so it was hard to make out what he said, but he didn’t want to get to specific b/c there was Japanese media at the banquet. It is a Mazdaspeed announcement of some sort, but it wasn’t clear if it was parts or a car. There aren’t any more cars to “MS” except ours, but my other sources didn’t dig up any info.
I also asked about when we will see an all aluminum engine, and what if any issues there are with an all aluminum hosing setup. Per Dr. Ianetti and others, there is no issue with aluminum other than cost, you need to reinforce parts of the end housings with some extra material, but other than that, Mazda could easily make a all aluminum engine. That would shave a good 50-60lbs off the engine.
I wish we had an answer as to the engine type for the BK team, the only hint I got was during a speech on the main stage, where the higher ups pointed at the GT 3rotor car and said that the GT car is the future, which may or may not mean they are abandoning the rotary in the ALMS car. The engineering that when into the GT car is amazing, they showed us a video of the development at the banquet on the development and design, you guys would be proud of the effort put into that car. The Mazdaspeed guys wouldn’t cave on giving Fred or I an answer, and I left my torture devices at home.
Well, off to the airport, if anyone wants any clarification on the above just let me know. I’m looking forward to Sevenstock 10 next year.
