I'm assuming you guys dyno reclassed the car. Where did the reclass land you? What base class and weight (and max power and torque numbers if that's not still top secret)? The first post in this thread says 148whp but that means comp. weight of 2109lb to be maxed out in PTD.

What about the water pressure sensor? I had one but it would display that I have 25-30psi all the time - even with the engine off for several days, so I took it off. I had mine on the hose right after the thermostat.

They don't allow Miatas anywhere near the 14.25:1 ratio for PTD/TTD. Those numbers are only guidelines.

pls understand Miata/MX5 took 10 of possible 18 podiums at T25 according to NASA. in reality. one of the class is ESR, Miata can't even run there. another is the top tier ES class, more of prototype and Cup car class, Miata don't run there. so basically, Miata/MX5 won 10 of "possible" 12 podiums. so no, I don't think weight/hp ratio is going down anytime soon..:giggle: |

E46 BMW's are another story. Greg Greenbaum will not class a small tired car with a favorable lb/hp ratio into what the books suggests a reasonable classification, which he's stated on more than one occasion. My research shows about a 2.5% hp/lb penalty for us Miatas. Thanks NASA.
Notice how many Miatas win NASA classes in sprints, TT, 3hr and the 25? If Greg will give us the same few % lbs/hp penalty for an E1 or E0 Miata, we'll happily accept it. |

+1. it is ~15:1.

^ I know that this is MT, but honestly to be competitive in ES the car would need at least 350-400whp, and over 25hrs, I don't see a 400hp Miata engine being reliable enough. I know that there are some super reliable engines on here, but I doubt that you could go in with any sort of confidence that the motor and trans would hols up for the full 25. If you wanted to do an ES T25 car I see an LS1/2 motor being the way to go. It wouldn't even break a sweat at 400hp, and as long as the oiling system was improved upon, I would expect a GOOD swap job to last the 25. And having Keith teamed up with us for this one, I could see FM and 949 doing a joint car.
That is purely my opinion though, and honestly I don't know all that much about turbo Miatas. I only signed up here because there was a good discussion going on, and I had run out of views. |

Not sure what you're complaining about. In sprint races, we have a few hp to spare. In the 3 hr enduro's we have a lot to spare. In the 25, we could have spotted our competition about 15whp (>10%) and still won even if they had zero problems.

we have been on the wrong tires (not on hoosiers) or not driving good enough. If that e46 had been at TWS last week i would have spanked him.

E0/1/2/3 have similar rules, like only 10 gallons per stop, no air jack, no pressurized fuel delivery. ES is pretty much open. |

Miata drivers might be getting a little too cocky. in ES, you will be racing against these:

Not really, he runs TTA not to get hasseled.

6 second pit stops for 30-40 gallons and 4 tires. E0 is a huge step. ES is a 200K Miata and that ain't exaggeration. For that coin I would buy a few year old GT3 cup car for 75-90k, spend maybe 50K getting in prepped, a few gentleman drivers writing 40k checks and a corporate sponsor to cover the rest.
I would definitely be up for helping out as crew for you guys at the 25 next year. Bob |

So really the question must be asked, is more power even really needed. I think that the reason the E2/3 cars do so well compared to the E0/1 cars is that they are so much better on fuel/tires/reliability. So running an E0/1 car would probably cost a ton more money, and likely not end with a better or more impressive result. The only realistic result that I could see would be getting a top 5 or possibly even top 3 overall with a very well built E0/1 car as long as it somehow made it through without any mechanical issues. As for an overall win, I don't see and "privateer" team taking down Mercer. (they beat everyone by at least 48 laps) Though I would love to see the chevy C6r team come out just to piss off the Mercer boys... Whatever the future brings, I am excited to see what happens, and hope to play a role next year as well. |
Ok maybe I said the wrong class. The prototype sports racers are ESR though. And it looks to me like the car I want to build would only fit in ES based on the rules however the other classes all pretty much require DOT tires. I would definitely be up for helping out as crew for you guys at the 25 next year. |

Hell, they could just run your car on a more mild tune, and as long as everything held up for the full 25 (which we have no reason to assume it wouldn't) it would be a force to be reckoned with. It certainly would have a good shot at pole position in whatever class it ran outside of ES.

^ I was surprised that this wasn't the response that I got when I asked if they needed/wanted help with the T25...
My name is Chris, and apparently I fooled everyone into thinking that I know a lot about Miatas... |
