1/10 Dirt Oval Gear Setup

Put tires at 1-3/16 stagger front and rear. 4.5 left 5.5 right, ( you need roll speed.) Are you using tire prep? How many sets of tires do you have? 33s fire like crazy on goat but u cant run them every week and goat. If its definitely a 33 track I'd be punching high 50s and be on goat. Put that right front down into the ground some I'd try 3-4 flats and see how it turns. You gotta get it turning before you worrie about gear. Should be able to flat foot a preditor. If hes lifting karts way wrong. Just my 2 cents.
They are 33s not sure what they are punching. When its only him on the track he doesn't let off the fuel but with other kids on the track he lets off to keep from hitting them, He did try passing on the high side last time he raced and learned fast that the high side was to loose when he smacked a fence post.

The best thing I can tell you from running my Bad Max on a similar track . Set 1 1/2 inch stagger front to start , 1 inch in the rear , get your % where you want it , then up cross 3% and add a puck of 5lbs weight to the front center , with the bolt going right straight thru the star . Don't know why , but that always helped me . And Tires , Tires , Tires . That track needs prep on tires and better track prep . JMO
That's close to what I've got his stagger at now, And yes the track is in desperate need of better prep. But in the owners of the tracks defense this is their 1st year running the track and they have worked wonders on it this year gets better every week.

When you can plug your spread sheet into the kart and adjust the %'s .
Then you would have the best thing since buttered bread .
Until then it's a tool to play with nothing more .
It's nice , it's accurate and it's quicker then a pencil and paper .
I can play around with it and my weights but translating the results too the chassis is a totally different situation .
IS this a good time to mention the next big thing in karting? Sliding weight, much like an airplane does when balancing the cabin weight before take off. It's an idea nothing more lol

It probably has been tried , lol , but the whole process would be to slow to react then counter react , as well as to problematic to achieve . JMO

Preditor racing is all about momentum. 90% of preditor races are won with tires. The rest is chassis setup and gear. The idea of prep is to get the tire to fire off before it has heat in it and makes it's own bite. Be carefull with aggressive preps as u will ruin tires quick. Invest in a durometer and see what they are punching. If you have 2 sets I would prep a set for each week and rotate them. Goat p is what alot of guys turn too on 33s. But you need to let them sit after you wipe them with it as it will drop duro alot.
I'll run a set of 33s for hotlaps and heat race take them off and be on another set for the feature and wipe them right before i push to the grid. Then they get cleaned and sit for atleast a week and I'm on 2 other sets next week. That way the duro comes back up some and I'm not killing tires. Typically get 2 seasons out of tires wiped with goat. Its unfortunate you have to kill tires to be competitive but like i said preditor class is all about momentum. Ask some of the bigger clone guys if they have any older sets of 33s they would sell. I wouldnt be scared of a set that was 2-3 years old punching high 50s low 60s just make sure you know what prep is in them. I also dont swap tires around meaning once I have a set of 4 they stay togeather and always get the same prep wiped in them no matter what. It's supposed to be a budget class but it takes alot of money and tires to keep up with the big guys.

100% correct!! It's tool! And like any other tool, your skill at using it is all important. It's just an adding machine. You give it input, it does the calculations and gives you an answer. It's only an aid to "your" analytical skills. Instantaneous answers to your input "what if I do this". Just a fancy calculator, no more.
