I wonder if this air to air intercooler I worked in a couple pages back will cool that off.

View attachment 336217

Is this going to have a hood, firewall, inner fenders, dash, side skins?

Just trying to figure out once you get some air to the charge air cooler, where is that air going to go?

You have high pressure air in front of it, but nowhere good for the air to go.

Is this purely for sandbox races or u4.

Just trying to grasp whether the intercooler has to rely on fans or if speed is going to help.

Then you have a fuel cell directly behind the motor, exhaust and intercooler, equals heated fuel.

Not to mention the heat soak coming off the trans radiating towards the cell.

Just not a good air flow path, and air doesn’t like difficult paths, whether that is pressure induced or from convection.

I vote for n/a, or methanol fueled. But good luck with getting methanol approved for nearly any Offroad sanctioning body.

Could do water/meth injected but that’s another system to fail and requires another tank sized appropriately.


Overall just a ton of self inflicted short comings.

Glad wasting your customer's money is a laughing matter to you, which up to this point is still very top secret to us.

Hopefully this one gets answered.
Let's all be adults here.
If there is one doc in the world rich enough, passionate enough about off roading, and dare I say it - crazy enough to pay David to build an offroad car for him...it can only be Nazir, right?

I have eternal respect and gratitude for him. I hope it's not. For his sake. But I mean it sort of has to be, right?

I'll believe it when I see it, he can afford to hire any builder he wants...

Anyway, no one has used turbine power in an ultra 4 yet--get a nice P&W with a couple thousand hp and a fancy high speed gearbox--lightweight, easy to package, no need for radiator and extra thrust to help with obstacles.

Just make the off-road equivalent to the F-35, then you'll be able to "jump" any obstacle.

Cutting edge would be a sx’s turned into partial helicopter. Rules don’t address height thru canyons and you aren’t deviating from 50/150 ft from course centerline.

Wouldn’t have to worry with rock section bottlenecks or shock tuning when you just fly 6’ off the ground or over any competition.

Was able to flip the radiator below the mid-rail, move the rear shocks perpendicular with the trailing arms at bump, and started on the bulkhead. Trick is gonna be removing the front diff. Looking at options for it to drop, or slide out the front.

There's a bunch of trucks like this down in eastern NC if you need to get any geometry off of one.

This is the best look I've had at 2 inch headers over the past few days. I feel like the car is asking for a stainless steel fire wall, which could mean the entire interior right side of the driver could essentially be stainless steel instead of aluminum. The larger (more surface area) I make the stainless piece of sheet metal will dull more heat. If I could create a forced air corridor between a stainless firewall, and aluminum interior, I figure that would probably be considered max effort to stray the heat. All hypothetical I guess, but a piece of thin stainless between me, and the headers is going to make the bigger difference.

I picked some trailing arm photos off the internet to look at my options. The first photo I dropped is the style trailing arm I believe I will end up running. Reason why is because it's completely made of laser cut chromoly plate, and I feel like I can shave weight by not using a heavy wall tube on the bottom side. I haven't had the opportunity to weigh (or calculate) the billet equivalent of what I think I want to run, but what I'm seeing is the chromoly trailing arms will be basically hollow. The ends carry less bulk as well. Looking at the billet trailing arms, I'm possibly looking at a binding issue at the link tab during articulation because the ends of the billet trailing arms look to be way more bulky, because they have more mass width wise. I don't know. I'm not going to completely rule them out, but I'm going to start designing a chromoly trailing arm because I feel like it's going to have a better strength the weight ratio.

Dude? Have you been in my house?!

that looks a lot like something he just built with Legos.

That already happened, twice, about 5 years ago, that never ended up getting finished.
Yea they were finished... by Woodlee.
