the best wheel base for racing

[noceros]

My wheel base is 83 in. the sr1 class is up to 105 in. wanted to extent to 92 or 95 in.what do you guys think

[Odyknuck]

Longer wheel base = better overall stability.
Shorter wheel base = quicker in the turns.

92" - 95" would be in the middle and a good compromize for both situations.

About 130" or so...oh, and 800 hp...just sayin'.

Are you racing short course or desert?

You’re making a lot of crude assumptions. Wheel base is not the only variable that establishes stability and control. As much of a concern is CG location, sprung and un-sprung weight distribution, roll axis, etc….you can have a short wheel base and more stability than long, and less total weight. For example, a lower more centered cg car will have more stability and shock control than a higher one, if you want the best of both worlds take a shorter WB lower and center the CG, keep the distributed weight and moment arms(fwd/rear, to CG) down.

You are correct there are other considerations however a general question was answered with a general responce. We are talking a UTV here are we not? Hard to get a lower CG without sacrificing ground clearence on them.

Not at all if your rebuilding which I assumed he was.

Well then I suppose we need more details on the OPs intensions before we can make a sound judgement call!

Agree, it is an interesting subject tho and VERY complicated hate to say. You can see the battle so far with Articat1000 vs XP900, with the Cat placing the rider closer to the “low CG”, as well as the bulk of the weight the engine mid-chassis, still leaving a whooping 13 inches of ground clearance, 90 inch WB, 1300 lbs.

XP900 has an 81 inch wheelbase, 1190 lbs, same ground clearance.

Hard to say without knowing exactly where the CG is on both cars whom the winner is, all we can say is that whomever knows how to optimize their Cg with respect to their dry weight, wheel locations, reliability, and cost will be the clear winner. Not an simple task my friend.
