How fast with short wheelbase?

Ok here is something to think about . Two fed's both cars weigh 1600 lbs one is 160 w.b. the other is 200w.b. same motor same distance away from rear centerline . The shorter car will have more weight on the front wheel's ! What dose this have to do with anything ? I am not really shure just felt like typing something .

Ok, I'm tired, was supposed to do club racing last night and it was called off as I was leaving the house (rain), I was up at four and at the swap meet grounds to prepare at five, it was 53 degrees at two PM, I was supposed to do test and tune after the swap meet, but was just cold, and I was just to tired.
I do not think you are correct, the front and rear tires will carry the same weight regardless of the wheel base.

No expert here but I have used a friends electronic scales on all four corners on our FED. Moving weight around makes a difference . We put the Optima battery inside the nose piece ( in front of the wheels).

Correct, moving weight around, forward and backward in the chassis would effect weight bias.
This is not the question raised.
Weight remanins the same in two different chassis, rear axle center remains the same, forward engine placement remains the same, the difference is the length of the chassis (distance between the front and rear wheels) Distance between the front of the engine and the rear wheels remains the same. Weight on all four wheels would remain the same regardless of the length of the chassis. Move the engine forwar and that would change.
I think??.

IMO if front end is farther out it will have less effective weight especailly under power,that just simple physics(leverage).The rear wheels have more levarge on front end while trying to pick it up.
I grabbed front end today and raised the front up about a foot without a lot of effort, I know on our funny carI could not have done it and motors are close to same distance.Now Im not small guy but Im not powerlifter either.
I would also think the more effective weight underpower would help handling if anything.
