Renesis_8

hey thanks l8apex, ill shoot u a pm this weekend.

i was looking thru the grand-am rules

9-3.2 Fuel Capacity - The maximum fuel capacity is 22 gallons.


2-14 Mazda RX8 (Prep 2)
2-14.1 20B Cosmo three rotor (Mazda Spec parts). 2.0 liter, 9.7 compression ratio,
3-52mm throttle bodies, maximum of 6 injectors, maximum fuel pressure 4.2 bar,
intake manifold is free. Call Grand American for parts list 386 947 6681
2-14.2 Minimum weight 2200 lbs
2-14.3 Six-speed transmission.
2-14.4 Maximum body width is 73.5 inches.
2-14.5 Front tire 280 /640/18
2-14.6 Engine set-back 5.125 inches from spindle centerline to 1st spark plug.
2-14.7 Complete rear wing height w/ end plates cannot exceed roof height.
2-14.8 Fuel capacity 24 gallons May use oil in fuel

Bern reported that we get a few laps per tank less than the porsches, and that is with an extra 2 gallons already. seems like we really need to get the fuel mileage up! But then again. Daytona isnt really the RX-8's strong course, its a horsepower course, we need the twisties!

p.s. if mazda still make housings that fits 3 spark plugs, the problem would be solved!

fuel was not a problem last year, we where getting better fuel milage than the porche's, it looks like they did theyr job and got better for this season, im sure MR. Haskell will do a better ecu program for the next races and the entire team will work hard for better results, speedsource always does that.

Grand Am allows them in both GT and ST.

I thought so too. We saw "Mr. Ceramic Apex Seal" Francesco Ianetti there talking with the teams.

Renesis_8

thanks for the correction, b/c i saw no use of ceramics in the rules =d

Where would they get the motors from if they were to allow them?

Yes, Dr. Iannetti is the MAN. One of the most unsung heroes in this game. He provides more products and technical assistance than people realize. He helps Mazda, NASCAR teams and even the NASA spce program.

Mazda has said that they want a 24 daytona victory, maybe they would be motivated to make a couple of engines

Generally speaking, a proper team fielding 2 cars would get about 12 to 15 engines. I just don't think Mazda Japan is interested right now. They've also lost a lot of people who were involved with Rotary Racing and the R26B in particular.

We'll see what the future holds and what they decide to do in the next decade.

I was talking to a guy named Mike in the garage area (I don't have his last name but I do have his phone number). He is working with an other guy to produce PPort 4 rotor race engines in the US. The template engine for this is coming from Australia. He is the the one that is suppose to get it working. One it is working the money guy will start producing these for sale. Mike will get to keep the original for his work.
He is interested in trying to port a Renesis. If anyone is interested, I can give you his number.

yah, mazda japan is only interested in DISIing things


haha RC, funny i was reading the grandam boards, they were saying a new ECU crippled most of the cars (trans failures, overheating, etc etc) last weekend and actually in 2004 or something a GT car won the race because no DP could make it across the finish line!

The Australian people often demonstrate great ingenuity and are EXTREMELY talented but making a 4 rotor suitable for serious endurance competition is a tough proposition. R26B was quite a device when it was current, the materials, the coatings, the third spark plug etc etc.

If Mazda Japan wanted to play, we'd see something.

both SS cars are heading down to mexico! and this time we'll also see the long awaited pair of 350Zs... I am very interested in how they do, they're running with the 3.5L VQ, unlike the 4.5L V8 used in the G35 GT. The G35 went thru 4 motors and coundnt finish, i dunno how the 3.5L V6 will like pushing out 400++++ hp....

oh btw, Berny if you see this, it'd be great if you can change the title of this thread(to just SS GT grand-am, or sth)! i thought about starting a new thread, but theres a lot of great info/discussion here to let it die!



Here is what I found on grand-am's site

2-17 Nissan 350 Z (Prep 1 and 2)
2-17.1 3.5 Liter VQ35DE ,13:1 compression,RRZ31-Spec 2 heads, 515/264 In,485/250
Ex. Camshaft ,38 lb crank piton /rod 902 gms.
2-17.2 Tire sizes are 280/640R18 front and 295/660R18 rear

I believe the unitech 350Zs arent tube frames.

P.S. the 350Zs are factory backed.

Rotary Reliability Brings SpeedSource Two Top 10 in Largest Class in Daytona Rolex 24 History

(February 12, 2007) -- With the off-season days clicking by at SpeedSource, team hopes and confidence were high for the 2007 Rolex 24 two-car effort, though the time was short to build and prep these 3-rotor big brothers to Mazda's distinctive RX-8 road car. 2006 had proven to the team the GT package had the right stuff, and with the added support of Mazda and Mazdaspeed, the team had the tools to compete head-on with the very stout 2007 GT field.

January Test Days again proved the GT RX-8 ready for competition, with the 8th quickest time in the field. Problem-free practice sessions allowed the team to focus on race prep, and from the drop of the green flag, team car No. 70 hummed through its paces for the first 8 hours with only a fuel rig problem to slow the team down. Starting off the driving rotation, team owner Sylvain Tremblay handed off to endurance racing veteran Nick Ham, followed by driver and team technical director David Haskell, with Mazda team driver Randy Pobst anchoring the line-up.

Tremblay compared the two seasons. "We came into this year's qualifying session with a time over 1.5 seconds quicker than in 2006, but qualified again in third. The 2007 GT field has clearly improved and raised the competitive bar." It is also the largest field of cars in the Rolex 24's 45-year history.

In its Rolex debut the No. 69 car, driven by Emil Assentato, with co-drivers Nick Longhi, Matt Plumb, and Jeff Segal, set a quick pace in the January Test Days and followed up with a 7th in class qualifying run by Plumb. The FXDD-sponsored car shadowed the field leaders throughout the race and came home in 7th. The motor ran flawlessly and only an errant traffic cone that punched a hole in the radiator slowed down the drivers' efforts. In a middle-of-the-night radiator change, the No. 69 crew led by car chief Marty Kintzi returned the car to racing conditions with minimal down-time.

Tremblay expressed his pride in both his crew and co-drivers. "We have grown as a team in the last year and I am proud of the effort of the entire crew. We overcame the difficulties of last year, and put two cars solidly in the top 10 in GT. That's a big turn around for the team and the entire Mazda program."

Though the cars were flawless, the team worked throughout the weekend to focus on and resolve the few problems they encountered. "When the No. 69 car had a pit road exit mishap during practice, the crew stepped up and got the car ready without missing a beat. Early in the race, we had fuel rig problems, but our guys were focused and rebounded."

Tremblay is especially proud of long stints put in by Haskell and Ham in the rainy hours of the night. "My co-drivers had their hearts in this race, and their efforts proved it. They drove consistently and took care of the car. Plus, driving in the middle of the night in the rain is tough, and they never let up."

On the restart following the lengthy red flag, the accordion effect of cars bunching up brought contact between the No. 70 and the No. 85 car. "The damage we sustained was more severe than we initially thought, and we lost straight line speed after the hit and the aerodynamics were not what the designers at Mazda had worked so hard to perfect. We hated to have the damage for our car, and hated it just as much for the No. 85, which was running a strong race."

The rain also played havoc with No. 70's radios. Following the red flag, and for the remainder of the race, the crew battled to reestablish communication with the car.
No. 70 car chief, Matt Martin kept the drivers and pit stops on pace despite the loss of radios. Pit signals and a cool head kept the car in the hunt.

Of the race end, Tremblay said, "With Randy in the car to finish out the race, we had no way to communicate that the No. 06 was gaining for position. After 24 hours, we lost fourth place by .26 seconds on the last lap, less than a single car length. That was tough, but to come within less than 4 minutes of winning one of the world's toughest endurance races, I am very proud of the team and the effort.

Technical Director and driver David Haskell summed up the race: "I guess overall everything went well for us in the race. You always try to prepare the best you can, but this race always seems to come up with something that catches you by surprise. The car and rotary engine preformed flawless. Everyone involve with this program did a great job. We just have to cross some more things off of our list, come back next year and win this thing. We're not that far from doing it."

SpeedSource now looks south of the border to build on the momentum of Daytona. "The Mexico trip will be somewhat of an adventure, but we anticipate the Autodromo Rodriguez to be better suited to our braking and aero packages, so we are looking forward to the race."
