In another forum someone posted a good question which is worth answering here" A lot of engineering went into these parts and absolutely nothing binds or hits. In those pictures the suspension is at full droop which is the minimum clearance between the bell crank and the billet chassis piece...

Thanks for the compliments. I've been trying to integrate the active dampers for two years and Henry from Chiron World Sports Cars is the one that finally made it happen. While I develop a lot of my own parts, I have no experience designing suspension parts and Henry is the genius behind this...

The next step in the rear suspension upgrade was to replace everything except the lower control arm (e.g., the uprights, suspension brackets, upper control arms and rockers). The stock rockers are composed of six machined parts and six screws whereas the new rockers are machined from a single...

I’ve been spending a massive amount of time working on the electrical system. I’ve retained a high-end German firm to design and manufacture a motorsport harness that will subsume the pile of sub harnesses that I have. More about them later. Stefan was able to squeeze a one-week trip to Boston...

During my last trip to the Bay Area I got a ride in Mesa’s SL-C. It’s a unique and outstanding build which gave me a case of tire envy — his 405s make my 345s look emaciated. During my most recent visit I invited him to watch Fleet Week from our deck. As you’d expect, the Blue Angels were...

LOL - Neil, you never fail to point out that something might go wrong with technology. Do you only fly on airplanes with carbureted engines or do you fly on jets? If the later, how do you look past all of the exotic materials and complex systems that might fail? While something can be said...

Paul, LIN (Local Interconnect Network) is a low-cost single-wire serial protocol. It seems that OEMs are increasingly using this for communications with simple devices because it reduces the number of wires and is less expensive than CAN bus. For example, the PWM version of the CWA400 requires...

The holy grail for many SL-C builders is a comfortable car on the street which can also tear up the track. While it’s impossible to optimize for both, technology can help transition between the two use cases. To that end, I’ve added cockpit-adjustable anti sway bars, driver tunable electric...

Permatex Aviation Form-A-Gasket No. 3 is great stuff, but I would ABSOLUTLY NOT use it for automotive fuel lines. You may be thinking that if it's used in aviation for fuel lines (amongst other things), it must be good enough for your project car. Not so fast. Aviation fuel has zero ethanol in...

Aluminum wouldn't be strong enough. The steel is coated and the solid rivets are brass. If installed properly will not move in any way shape or form against the aluminum (the floating part is captured within the steel body). I don't see any issue with steel/aluminum corrosion in our application...

It depends on how the car was built. IMO, you don't want screws visible in the door jamb. The tub is attached to the chassis and if trimmed properly, the body and tub do a good job of indexing into each other without the need for visible screws in the door jamb. If you're not having squeaks or...

If you're going to drive your car in, you need a side hatch. However, I wouldn't be comfortable driving my SL-C into a trailer. The Aerovault comes standard with a winch, a battery charger and water-proof charging port which allows you plug in an extension cord (it also charges while being...

I have an Aerovault MKII and love it. Aluminum monocoque, enclosed quality axles, quality tires, iconic/aero dynamic shape. Given it's light weight, quality engineering/materials and focus on aerodynamics I guarantee that you won't find anything that's as easy to tow.

I used icengineworks to design a complex equal-length 180-degree crossover exhaust (it actually crosses under the dry sump) The primaries step from 1-7/8" (green) to 2" (yellow) so I used multiple kits. The merge collectors fire in a proper rotary sequence, one side is CW and the other is CCW...

My wife doesn't think so! I'm working on a plugin for my website so that you can interactively spin them 360 degrees. Me too! It will happen in 2024. Over four and a half years ago I modified the fuel filler neck to clear the throttle body and the induction tube. The mod isn’t difficult, but...

If the air cups take 2/3 less space than the RamLift cups on the dampers, you'll be able to solve the front no problem and they might make the rear feasible.

Jeff, Pnut installed a pneumatic lift system and used a tank that was much smaller than what was included in the kit. He only has pucks in the nose, so you'd likely need to double the size that he had. IMO, you only need enough capacity to do a single lift. Most available tanks will be...

I loved my headers in raw stainless steel so before they were coated I had them photographed. The photos just arrived. He did a several 360-degree shots using a rotary table. I'm going to convert them to video, but here are few. Note that the joints that aren't as pretty are where the tube steps...

Ken, Thanks for the suggestion. They're installed, the splash of color is growing on me and I've decided that I need to find more parts that I don't change so I'm going to keep them as is Rus, I'm glad you're enjoying the writeups. They help me remember what I've done and hopefully provide some...

When I made the initial decision to run E85 I was aware that everything in the fuel system needed to be E85 compatible and that I needed to add an ethanol content sensor. I subsequentially learned that E85 contains 40% less BTUs than gas which means that the system must flow more. Since E85 is...
