My car is using an 8 stack EFI on a Coyote but I do want to use a MAF on it. I do want the weber looking throttle bodies to be visible so a transparent air box is needed for the MAF to work for this configuration. The challenge is that the air box needs to be quite a bit wider than what is...
In my case, I probably used every bend radius available. It would be nice to use all the same radius but that's probably only possible with very simple header layouts. I tried to stay away from tight radius bends due to flow restrictions but there was a couple of places I had to use them. My...
If you are putting an oil cooler on a street driven car, you will want to have a temperature control valve on it. For track only applications (where engine is running in top 50% of rpm range), you most likely don't need temperature control. The most common complaint from Cobra owners who have...
It's not a bundle of snakes header but probably even more complicated layout. I decided the plastic mockup approach wasn't going to tell me everything I needed to know, so I built a "prototype" using cheap steel mandrel bends prior to building the actual header in 304 SS. Probably takes more...
Gas Tank Fabrication (Part 3)
The top panel is now welded in place with big fat weld beads on all four sides. My lesson learned from prior gas tank fabrication experience is not to skimp on the filler rod. You’re more likely to get pin holes in the TIG weld if you don’t have a nice “fat” puddle...
Gas Tank Fabrication (Part 2)
After thinking about the feedback I’d received from multiple sources, it lead me to these choices: extra bracing for the side corner weld seams, addition of a sump in the tank bottom, inclusion of a venturi jet pump powered by the EFI return fuel, and using baffles...
Here's what I made for my Miura project for pedal adjustment.
It's simply a 1/4" plate of 6052 aluminum with a series of holes drilled into it. The pedals are mounted to the plate with screws counter sunk from the bottom side of plate. I then used button head screws to fasten the plate to...
Now that's a very sophisticated gas tank!! I've had fuel starvation issues upon hard acceleration in my Cobra when the fuel level gets low. That's what I'm hoping to prevent with the GTO.
Trap doors in the baffles sound like some fabrication work but should be simple enough to be maintenance...
Gas Tank Fabrication
The GTO has been undergoing the homebuilt car sorting out process and has just over 2,000 miles on it now. One of the issues it has had since I moved from a location at 800 feet elevation to a location at 5,100 feet has been a “vapor lock condition” that can occur when...
Here's a couple of pics from one of my hand built cars where aluminum was riveted and bonded to chassis tubes.
The aluminum used was 3003 alloy and .050 in thickness. For the engine compartment panels, I used anodized aluminum which I'd recommend for panels that are highly visible because...
I suspect that material expansion, especially stainless steel, is a factor that we underestimate and then it surprises us. So a test for leaks in exhaust system done at 70 degrees F is not a valid test. I think you'd need to test for leaks at the normal to higher operating temperatures of the...
I built a car from scratch, including the chassis, and took it through the registration process in CA back in 2010. It was the SB100 process. The CHP was required to provide the VIN for the car and they riveted a plate in the door jam with the specially issued VIN. I just made an appointment...
If those are "single slip" connections to the collectors, you'll likely always be challenged in getting them to seal. You need double slip connections and even then they sometimes leak enough to cause O2 sensor misreading. I've been surprised on one of my cars on how challenging it is to keep...
Augment Wheels ( https://www.augmentwheels.com/ ) custom made them for me. They did the CAD work based on pics of the Campanola rims that originally came on the Miura. They also did a nice job of making them look like knock offs but still use the wheel studs/lug nuts from the C5 hubs. I...
