High speed G-maxx for ISC event, 100mph or bust

[Rivermaxx]

A swiss cheese body is definatly a big NO! I want to reduce drag not increase it. A body is a must! aerodynamic is key and if I run without a body it will shed about 10 mph off my speed atleast. I know where you going with it though. Your thinking I am going to have the same problem as jzemaxx with the truck taking off because of the body catching air. For one thing my body is definatly more aerodynamic and it sits way lower to the ground the hood is more sloped creating necessary down force . A couple things I am thinking about doing doing to prevent blow over that I know work is: The back of the body will be probably cut out allowing any air that sucked up by the fenders to escape out the back. It also will create a low pressure and help keep the car planted. I plan to run a little rake in the suspension also to create more frontal downforce. Batts are being push as far forward as possible. Thinking about making a front splitter(kinda like a front wing) out of a foam bumper. I also plan on taping the sides of the body to the bottom of the chassis with heavy duty clear packing tape, its amazing they line up perfect.

A little update I just put all new avid bearings in the carriers and new ceramic bearing throughout the transmission. I also put graphite dry lube in the cvds with boots and pillow ball socket also. I set all the pillowballs perfect by measurement and adjusted all of my toe in perfect, check and double checked.

well, it's a rock and a hardplace. no body= no lift, so you don't need the downforce the body creates. Add the body, you have lift and need the downforce. Of course rules dictate that the body be on.

I really think it would be worth a try once you get to testing to a/b a body with/without holes and see what happens.

I also envision an indy car style front wing that is as wide as the trucks wheels. That'd be awesome.

Just figure out how to slow down the air going over the top of the body, without causing additional drag, and you will get rid of the lift effect (bernoulies principle).

Aerodynamics is a tricky thing - there's a reason automotive and racing companies spend a fortune in wind tunnels.

Here's a thought - most leaf blowers can flow about 100mph - use one to try different things. Use a stationary video camera to record the various configurations. Maybe even get a buddy to bring theirs over so you can get more volume. Got any old smoke bombs laying around - glue some of those to the ground in front of the truck to create smoke to help see the air.
