Scott, Rotax mini max has a "Spec Gear" and always has had... [/quote]
Jim,
Actually – when we first got into Minimax it was open gear. At some tracks, the Minimax were faster than the Juniors – which was crazy. They put in the spec gear to slow them down – and inadvertently they created the “Turbo” problem.

Wow John, I didn't know that. We only ran a few mini max races this year and I thought the set gearing had always been there. I can't imagine how fast it would be with out it.
It must have been rough starting out in mini max with an open gear and then (slowing down) to the fixed one. I know why Jack likes the Jr. rotax so much more.  |

| There has been alot of evolution to the mini max package, not only was the gear open but the original weight was only 235 or 245 and you had to run yhc bridgestones and the min jet was 155. |

The spec gear we have in the MM class (13/82) hardly slows them down much - 1 or 2 seconds, at most, in a 40 second lap. 1 or 2 seconds spread out over multiple corners (where accidents typically happen) is hardly conducive to creating "space" for eye/hand reactions.
What the spec gear does do, unless coincidentally matched to the track, is create random speed differences - namely bogs and turbo. It is these speed "hicups", that are random/unexpected and mismatched to the field, that can create accidents.
MVHO,

BUT it's not the same, and it's easy for the driver to get. angus could get turbo whenever he had enough room to get to about the right rpm to then make the jump. it's a burst, but not nearly as drastic as the minimax burst.
i think the only way to limit the minimax turbo is with a rev-limiter. we can get turbo with a 148 main jet, so limiting that isn't the fix.
someone in canada will get it soon. i'm sure stoll is getting it. |

The mini max deal is completely out of hand. Its the only rotax class I currently participate in, so I can't speak for any of the other class's, but I assume its more of the same.
I fully expect to get beat as far as horsepower, compared to guys like stroll, did anyone notice who the kids tuner was in ocala? Mike Wilson for anyone not paying attention. And Jordan Perry still looked much better through the infield, hell we were faster than stroll through the infield. The thing looked like Mr. Plow if you ask me. Did I mention the kid completely cut the track, skipped turn two, and passed Jordan in the process and still didn't get penalized. Must be nice.
Ok, so I guess my point is, its more certain people that think they're Roger Penske who screw things up for the rest of us looking for an even playing field. I would say 95% of the mini max's are pretty close, but when you buy 100 motors and mix and match all the best parts, what do you expect?
Anyone who knows me, and who I work for, knows we put in the time and money to be able to compete. I don't want to hear, oh your go kart was to tight. What does that have to do with us beating these guys off the corner, and down the first half the straightaway, and then having 2 guys blow by you from 5 cars back at the very end of the straightaway, rant over. |

Might not have to figure out that pesky "Turbo", but atleast in mini max you always know what rear gear everyone is running.  _________________ Rick Sweeting

top fuel dragsters were getting to fast and blowing up far to often so the rule makers changed rules. By doing so they had the racers re focus their efforts into narrower channels. 80% nitro, dont have to worry about the fuel. Spec pulleys on the blower, ok. Spec gear ratio, figure how to work around that. The end reslutls of trying to slow them down with rules, they are going faster.
Formula one, smaller wings, much less add on aero pieces, going to save money improve passing and slow down the cars.... Practice for Spa, the announcer said they are making more downforce now than they did before the rules change. Testing ban, gonna try some weird stuff at the practice days, or bolt some camreras on and do some "promotional camera shoot driving" oh yeah its on the latest and greatest car we made. dont mind all those other cars we have spare sitting letting some kids have the job of dusting them fool you, this is the only car we could run.
My point is, spec the gear, spec this, spec that, racers being racers will do anything to find an advantage over the compitition. Spec something else and we as a group will find a way to find an advantage, and complain when someone figures it out before us.
When everybody else is maxed at 10, we want to go to 11. |

"Spec" rules are more about controlling costs than reducing speed.
It simply prevents people wasting time and money on needless equipment and areas. _________________ Chad
