What's new

“Brophy Jeep” Street Legal Ultra4 4500 class CJ6

She warm brother :laughing:
And that's just doing a warm-up with run-up hubs on, no load. :laughing: But it does it for 24 hours straight, so it doesn't seem to mind.

Enough of the derail, been watching this one from the background, killer build you have going here Rockchump looking forward to seeing it out there doing it. :smokin:
 
I like that even OEM professionals use the same folding table I carry everywhere with me.
I have wired many rigs on this thing.

Now that’s a race car! So cool I could crawl around and geek out on that car all day!!
Thank you! I appreciate it!!

It's an incredible car. After ~10 years in pro Motorsports it's the only car I've ever been around that I could find less than a couple of 'why did they design this part this way?' Pretty much every component was well placed and thought out. But that's how you win Le Mans multiple years and absolutely stomp everyone around the world for years. :laughing:


What that?
Yep, gt1guy nailed it, that's the carbon airbox and filter feeding the drivers side turbo.
 
Anyone know what's inside that expensive header wrap?

HeaderShield is a bi-layer insulation and encapsulation system for anywhere you want to keep the heat in or out. Consisting of special, inner insulation layer and durable, stainless steel outer shell

"Stainless outer shell" is going to have to be very thin to form around headers. That's not exactly ground breaking and the thermal transfer properties of stainless are well known. So what's under it?

The list of what doesn't transfer heat isn't exactly a long one.

Ceramic in some form of matrix?

Carbon in some form of matrix?

Both in some form of matrix?


The stuff on that Audi LMP looks beat to shit. I'm sure it doesn't have a easy life and it may have been on there a while, but with the way parts would be timed out on that car, that stuff looks horrible.

Bucket list race to go watch!! If you need a water boy I’m about to renew my passport! lol

Never cut it off, but nothing obvious to see in there when you peak through the pass-through holes for getting to the manifold nuts.

Yea, it's on vintage car. When they campaigned these cars the manifolds would have been lifed-out and tossed in a dumpster, I guess they weren't worried about the poor bastards wanting them to look good 20 years later when there were no new manifolds left :homer: But to me that's a testament to how tough the wrap is, these manifolds may well be ~20 years old and have 15k KM on them. Definitely a way harder life than any LS/ultra 4, etc will ever be on them, at least in terms of heat. Rock strikes, mud etc I can't speak too obviously. I could post pics of the same wrap on a new V10 manifold, but you can look at the sales brochure to see pics of it new. Haha

As far as the manifold on the LMP car, the flanges get inspected for cracks regularly. Sure, they could be sent out to get rewrapped, but the wrap still does its job of protecting the components around it. It would be a different story if the goal was to squeeze every bit of thermal potential out of the turbo system, but for an old guy to go out and run 45 minute races and wax the field, they work just fine. Vintage stuff is a whole different world for better or worse.

That makes me feel better for wanting to spend the money on the good stuff. I’ve had a buddy literally slow cook their feet from KOh with similar setups. Plus with trail wheeling I didn’t want to worry about cooking my feet being in the car a few hours at a time especially since I’m dumb and like wheeling in flip flops! lol

Ok, that all makes perfect sense. And you're right, it's also a testament to how well that wrap lasts.
