Ok here's 2 more the edges here appear good .
Do the tires in post 182 have the edge ?
Worth the time and little cost.
I understand using less prep and more air pressure as the night goes on and a track gains grip but what does opening up the split in air pressure do ? Say going from no split or one pound to two or maybe even a three pound split.
If the track gains good grip and you stay on straight up air kart may be to snug, the split helps to keep it free It's not common to go more than a 1 lb split with a flat kart, more split is used with champ karts.
when going to split do you mean adding air to the RS tires or taking one pound out of the left ? Also how does a split free a kart up ? Does it delay the weight transfer a little bit ?
Remember as track gains grip you want to run as much air as you can, SO you would add air to rights, and possibly both left and rights, I'm NO engineer to explain it 100% in detail, so dumb guy's explanation would be the higher air keeps the tire from being in the track to much, would stiffen the side wall ( spring rate ) which would resist transfer, Don't know that air pressure change affects timing as much as some other adjustments like cambers and casters would, but as stated above it would resist transfer more.
I would want them sized close before Internal rolling & if wiping during the week , plus of course you need proper stagger for the race so again size before PRW to race, nothing worse than fighting stagger to race. With that being said you will always be tweeking size between prepping them.
I have never prepped internal yet, but it seems like they grow better when prep is in them. Its all about these tires. I am sick of it really. But its what has to be with dirt karts. lol. I need to get some money saved and give you guys a call. That is my plan.
Each build varies some only the dyno confirms ideal, top builders are turning 7400 + If I did not have that info or access to a dyno I'd try 7200 and see what it does, that's a newer build I'm NO motor guy I would imagine that would vary depending on which generation, hopefully a motor builder will chime in.
