Rotor,how long does that engine last? one pass maybe 2
both engines are capable of the needed hp, the decicion is up to mazda and the PR potential of the race program

im sure they can make a 500 hp 4 banger as well as a renesis, but as I said before the decicision will come down to PR and spreating cost

I still feel that Mazda needs to stay with their roots and what has always worked for them. 4 cylinder engines haven't worked for them.

In this case, remember, MNAO is the one supporting the ALMS program, and they do have much in-house engineering experience and development with boosted DISI/MZR engines... The same can definitely not be said for the RENESIS, for which MC (Japan) has done all development and engineering. And without MC on-board 100% with the ALMS program, there doesn't seem to be much choice for MNAO against the Porsches, Acuras, etc... Of course we can always hope that the rotorheads at the company (MNAO), which btw are influential, can pull a rabbit out of the hat!

Only after they get these 2 issues worked out and see how fast or slow the car is should they consider different options.

The difference this next season though will be that instead of being in last place and getting 4th in class, they'll be 7th or 8th and in the runnings for nothing.

I guess it's easy to see where the rotary focus has shifted to. Mazda's goal has been to win all 3 big 24 hour endurance races. The rotary is the natural candidate for that. They won Spa Francorchamps way back when. They won LeMans in '91 and that leaves Daytona. Look at the new Grand Am 3 rotor we saw at Sevenstock. That's a definite commitment to that program. That seems to be where the emphasis went and hopefully there's a good chance they can win it.
Does Daytona seem a little less impressive these days to anyone else now that they're NASCRAPing it up? Don't get me wrong, I love the hell outta that GT RX8 (even if it is tubeframe) but Daytona seems kinda like the Indy500 since it's just IRL now...
And to bring this back to topic, I think Mazda should focus on my personal Big Three: Sebring, Le Mans, and Petit Le Mans.

Mazda has more class wins at Daytona than just about anyone. I hope you don't mean an overall win with the 3 rotor Gt class RX8. It ain't gona happen. They won Daytona first time out in 1979 with the RX7 in the GTU class. Racing beat has also won in the GTO class which is basically the same as todays GT. Under the current rules Mazda does not have an engine that can compete in the Daytona Prototype class. A four rotor would have a chance but is unlikely to ever be allowed.

The likely hood that any GT car wins the Daytona-24 overall now a days is very slim... The "Daytona" Prototype racers is where it's at with Grand-Am... and unless most of them fall out, a GT victory is very difficult.
I do know that there had been talks between Grand-Am, Mazda, and 3rd parties to allow a 4-rotor in DP class a while back, but they went no where, and that's where they're likely stay...

Just read on both the ALMS forums and SpeedTV that Dyson is supposedly going with two of the next-gen Porsche Spyder RSes in P2 next year. So whatever Mazda throws out there will have to deal with 4 Spyders, 3 Acuras, and a quick Radical and plucky Lola, which will possibly be running updated aero.
Good times!
As a side, P1 is now just Audi and Autocon running one (maybe two) very outdated cars.

Its too good, with 2 speedsource 3-rotors, i will be satisfied watching just GrandAm GT. They're going all out in the 07 season, we could even see some 1-2 podium finishes!!

Here's the press release dated 12/8...20b. As stated earlier in the thread it's too bad they aren't doing a turbo Renisis.

Speedsource had one of the 3 rotor cars out at Sevenstock and even did a presentation at the banquet about what went into that project. They are impressive. I've got some great shots of the enbine bay.

Actually I may have to repost them. I didn't put those pics up in the Sevenstock thread. I did load a couple into another thread but admittedly they were irrelevant to the thread topic and another admin deleted them! Damn it! I'll load them up here when I get to my other computer. That's where they are stored.
