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...

Thanks to Brian for pointing out the Genie GR20 as a good candidate to use as a man lift type elevator for mezzanine access. It checked all the boxes: battery powered, drivable, compact footprint, easy step up/on from the floor, and 20+ foot vertical reach. I'd been keeping my eyes on...

So because of tight spaces in my Miura chassis and to optimize the hose routing in those tight spaces, I oriented the oil radiator with ports on the side. In on the bottom port and out on the top port with an oil thermostat being directly upstream/downstream of the oil radiator. So unlike...

I suspect fuel boiling at the fuel pump impeller more than injector heat soak at this point. Maybe I'm wrong but relocating the fuel pump into the tank will tell me. This car is using a GM ECU (early 2000 Camero). I don't know if it is measuring injector impedance or not but I'm hoping the...

I can only halfway answer that question at this point. The installation is complete but I have yet to do an oil fill and/or attempt an engine startup. As to installation, the MMR external cooler kit appears to have good quality parts and I didn't have any major issues with installation other...

After having the engine stall from this issue, the engine would start fine after waiting about 20 to 30 minutes for the fuel to cool down. Until the fuel cooled, the engine wouldn't restart at all. I could tell by the sound of the fuel pump pre-start if fuel had cooled enough for restart or...

Thanks for the compliment! Not my intent to start envy but to share some ideas for things that can make out hobby more enjoyable. We are under going a major remodel on our primary residence. Part of the "grand plan" for the garage is to use it as a warehouse for our belongings while the house...

So my garage/workshop build is winding down (which is a good thing) but the last couple of things came in very large containers that required trailering in and a couple days of assembly time. I've been thinking about getting a 4 post hoist for a while and finally pulled the trigger on it...

Hmmm...interesting question. First off, it's driver/passenger safety I'd worry about, not inspection (because there isn't really a "safety" inspection from my experience with homebuilt cars). I'm guessing the pictures shown don't do a good job of showing the context so I took some...

Dash Console for Gauge Panel On the Miura, the center dash console housing the small gauges flows downward to seamlessly connect with the center console. As such, I need to make sure I keep this in mind and design in a way to interconnect the two while fabricating the dash console. My idea is...

Thanks Howard. I think I have a good understanding of what's going on. I'm guessing a person who could back this up with actual quantitative analysis is likely busy in a day job in auto industry and not hanging out playing with their automotive toys. I dug up the Davies Craig Installation...

Thanks for the information on "bypass thermostats" (it's helpful) but is somewhat of a different topic than the question posed in post #58 https://www.gt40s.com/threads/electric-water-pump-how-to.57366/post-588792 I think the question of how best to quickly get the coolant system up to target...

Hmmm...all the recommendations I've seen for EWP use is to eliminate the Tstat and use a sensor based EWP controller. Certainly that's the recommendation from Davies Craig in their installation instructions. Does anyone know if the OEM cars that use an EWP do so without a Tstat? For example...

Test fit of gauge panel I bought a Mitler Bros. 2 1/16” two piece hole punch to make the holes for gauges in the panel. First is to drill a ½” hole centered where you want to larger hole, thread the bolt through the hole and use to bring the punch pieces together and make the larger hole...

So I'll dabble back in the theoretical with this question (that is unless someone here has actual field experience with this scenario). The scenario is a mid-engine car with an "adequate" coolant system and then it's changed to go from an "inline" physical thermostat to a sensor/electronic...
