    Brian, to my knowledge only two builders have put the radiator in the rear. They did so because they wanted storage in the nose. IMO, the best place for the radiator and condenser is the stock location in the nose. In any event, if you moved the radiator/condenser to the rear you wouldn't have a...

    Brian, clearance inside the nose varies widely. Some builders have relocated the radiator to the tail and have nothing except a trunk in the nose (e.g. Mesa and Rumbles) and others have everything but the kitchen sink; Nose frame stiffeners Battery Hydraulic lift pump Hydraulic lift pump...

    Mason, the radiator outlet will be made out fiberglass and it will be bonded to the nose. It will be fed via a fixed duct, made from aluminum or fiberglass, that's sealed to the shroud. I'm currently working on the outlet size to create a diverging-converging duct to maximize mass airflow. There...

    Brian, I assume you're asking about the green box immediately behind the door. If so, that illustrates the available space between the monocoque and the body. Below that green box is where the cooling, heating and A/C lines go. How much actual space you have depends on where those lines are...

    Brian, those tail lights won't be easy to blend because the back of the SL-C is flat whereas the C7 is curved. I'm completely reworking the back section of the tail to fit the curvature of the lights. If I recall correctly, the arc extends the tail about 3" in the middle. The picture below shows...

    Back to working on the adjustable pedal box. I purchased a compact ACME nut from McMaster, but I realized that there was no pressure rating for it on their website so I sent them an email inquiry. Here’s their response… Let me think about that failure mode… If the nut doesn’t hold up to the...

    I was away from the car for a month so I had spent a lot of time designing the adjustable pedal box in CAD. I got to spend some time with the car this past week and the CAD fantasy didn’t fit reality. Specifically, the Front Suspension Race Cage wasn’t were it was supposed to be. I’m sure my...

    Neil, I was originally planning on using 4130. However, when I uploaded the design to 3DHubs to get a CNC quote, the only options for alloy steel were 4140, 4340 and 1215. Joel, at this point, I'm not planning on putting any sound deadening on the floor around the pedals... but time will...

    Continued from previous post... CONNECTIONS The reservoir and pressure lines for the clutch, front and rear brakes will be connected with Staubli quick disconnects. They have a lot of options, so I need to mock everything up to figure out which ones to use. Each connector half will be labeled...

    I want an adjustable pedal box for several reasons. Firstly, I can, with 100% confidence, state that I wouldn’t get the pedals located in the right place the first time. By the time I got it right, the floor would likely look like Swiss cheese. Secondly, I hate doing anything in the foot box...

    Thoughts around SLC as a race car.

    The SL-C's chassis is very stiff. The Superlite website provides the following table and you'll note that the only car with a stiffer chassis on the list is the Ferrari F50. However that number doesn't include the dropped seats which adds triangulation and is now a standard feature. More...

    Nose hinge

    I assume that Fran is really busy given that the Covid19 lock down in Michigan has just been lifted. I would suggest that you get pricing from Fran and figure out how many committed orders there are. They would likely help move this up in his priority que.

    Abe welded the coolant expansion tank. This was the first time that I had used SOLIDWORKS’ sheet metal features. Spending the time to ensure a 50% overlap for all edges resulted in perfect fitment with optimal corner weld joints.

    Removable doors

    Chris, I have the same problem with my trailer. It has a winch with synthetic rope and a remote control. Works great and there are zero concerns hitting anything because you can walk around the car to make sure everything is fine. You can also let the car cool before you put the cover on. The...

    Most steel parts provided by Superlite are either powder coated or zinc plated. However, the following parts aren’t coated and they quickly begin to pit even when kept in a climate controlled garage: Ball joint plates (4x) Lower shock pins (4x) Rear suspension pushrods (2x) Toe links (2x) Rear...

    Question on SLC Brake and clutch lines

    Neil, I completely agree. All of the regs that I saw dealt with pressure ratings, temperature and corrosion testing, etc... zero mention of the type of flare. However, logic doesn't always work when dealing with a bureaucracy ;-) I think AN is probably legal everywhere in USA, but maybe the...

    Question on SLC Brake and clutch lines

    Neil, I have heard that some people have had street cars fail inspection with AN fittings on hard lines. Specifically on some forums (including this one) and from a reputable shop that replaced the brake system for a car that failed inspection. That said, no one has ever pointed me to any...

    Question on SLC Brake and clutch lines

    BTW 45-degree double flare in stainless steel is a PITA. I bought this tool from Easton and it's amazing. You don't need it if you're going to use something softer, but it makes stainless easy to do. If you don't want to pick one up, you can send me a USPS label and I'll lend you mine...

    Question on SLC Brake and clutch lines

    My brake and clutch lines weren't even close to fitting on the front half of the car (the rear half fit pretty... well until I changed everything). In any event, mine had the same unions in the middle of side pod. This would be OK for a track car, but it's a bad location if you're going to...

    Radiator Bleed Setup Question

    I have a radiator bleed on on my car, but I have no practical experience -- the engine would have to be running for that. Air seeks the highest point, but the bleed line must be routed down to pass under the door before it can go up into the expansion tank. It's not clear to me how well air will...
