why it got 5 guys standing around with hardhats?
Will there be an LGP model?
Why is the rear wms so much wider than the front?
How much clearance is there between driver left thigh, and driver front tire at full lock and full stuff, when steering towards the driver side?
Why the nose heavy design with what 48”+ long rear links?
Just seems like rear sprung:unsprung mass ratio looks low or close to equal.
What kind of software is this?
Could the bottom end of the engine be rebuilt in a trailer , in the car, in the rain and mud?
i think that’s a critical design consideration
why front engine?
Such a simple question that demands an acute explanation. I feel like this is one of those worm hole questions that I need to navigate with precision.
I would venture out there to say that most everyone knows the challenge an Ultra 4 race car faces is climbing hills, rocks and attempting to track through the desert at really high speeds.
Let's assume that when the car is going up hill, that a large total weight percentage of the car is putting pressure on the rear end. This begs the question of why? Why would I want to put the engine in the rear of the vehicle, loading more responsibility onto the rear end? I have a perfectly good race duty front suspension. I'm not going to treat the IFS system on the front of this car like it's fragile. No. I'm gonna charge it with community service.
For me, this boils down to 2 things.
1 - Having enough weight on the front end to push the tires back down to the ground as quick as possible while I'm hauling the mail over bumps. I have to be able to steer this thing. If the front end of my car is bouncing around and flying in the air, I have no traction to steer.
2 - Get the front tire patch over the apex of a ledge and I've won most of the battle. Given, your gonna run into spots where the talent tank needs to be involved, but if I'm traveling over 3 miles per hour I've lost all visual and mental acuity with the rear end. It's not taking up any percentage of brain space at this point. I'm full bore on getting those front tires in position to climb over a correct line. Apex, apex, apex, I'm just zoned in on the rocks in front of me getting the weight of my front tires on an apex, because if I've done that, I've already beat the bully.
Most of us know what the little Rock Hill looks like at the flats? As soon as I had 4 tires on that rock garden, I would be setting my front tires up on a line half way up that thing that would allow me to just rip on the throttle, and come off the top in a fury with all 4 tires diggin for a trophy.
I would go out of my way to have a larger percentage of weight on the front half of the car.
Sorry to say you got some learning to do.
What you explained is not how an ifs rear engine car works at all.
Google polar moment of inertia.
Research the effects of sprung mass vs unsprung mass.
The front tires are easy to control bc they steer.
Controlling yaw in a dynamically changing environment of tires that don’t steer is a different but connected issue.
I didn't explain an ifs rear engine car. How many rear engine cars have your raced? I've raced 3 different ones.
