Randy, thanks for the compliment. Lots of work and rework to get it the way that I want it. The heat shields for the CV boots are finished. I designed and laser cut the flanges from 1/4” 6061 and the guys from Back Bay Customs formed the shields from 0.062” 5052 and welded them up. So that’s...

I was looking for a local shop to form some panels and discovered Back Bay Customs which is about 60 miles north of Boston in Portsmouth NH. After seeing one of their cars in Boston, I spoke with Adam, the owner, and decided to haul my car to the shop. I’m very picky about my car and I was...

Greg, I live in MA and it's the worst state for this. I had a cobra titled, registered and insured in NJ for 20 years. When I brought it MA they treated it as a salvage car. You must go to a State Trooper run facility with the proper paper work and receipts for the car. Any donor parts must...

In a previous post I modified the stock fuel tank to convert it to a FIA-compliant fuel cell. The challenge is that to replace the bladder in a SL-C with a tub you must; remove the windshield, center body, cage, seats, tub and fuel tank close out panel. That’s a lot of work, especially given the...

My supercharged LS7 fits under the rear window without any issues. It's a Harrop which I think is taller than low profile corvette style intakes. Note that if you use a Daily dry sump and the right transaxle, you can drop the engine several inches which, in addition to lowering the CG, will...

Having finished the X-pipe and oil inlet heatshields, the starter heatshield was next. However, when I went to install the starter, it collided with the catalytic converter. How the F did that happen? Not the first time that something was overlooked because I didn’t have all of the relevant...

Scott, You are correct and I've been looking for a solution. I considered using hanging pedals, but there are challenges doing that in an SL-C and I didn't spend much thinking about it. However, I figured out that if I removed the mounting flange on a GEN1 iBooster, ground the cast aluminum...

I contacted tech support and the device is compatible with E85, but, as you might expect, it isn’t compatible with foam in a fuel cell.

It's a good idea to run a custom-built engine on a stand or dyno before you drop it in the car. That said, it will likely take you longer to get the kit than to build the engine.

All of my flexible hydraulic lines are stainless steel encased in a rubberized coating. As you can see below the texture of the underlying stainless is noticeable. That said, there is no printing and I like it a lot better than the basic stainless line... it's really nice stuff. I cut it to...

Chris, As others have said, you don't need and in fact might not be happy with 1,500 HP. Most people will tell you that 800-900 is too much. However, I think your $100k budget for the car is probably a reasonable budget for a reliable mid-engine drivetrain at your top power level. My engine did...

The left merge collector is where the stock oil filter goes, but even with a dry sump pan I had to modify the oil inlet fitting as described in a previous post. After all of that work, things are still danger close. The only route to the inlet is to cross the oil line in front of the...

Other than the exhaust tips and ceramic coating, the exhaust system is done. I now need to fabricate eight heat shields to solve all of the self-inflicted heat management challenges. The first heat shield protects the transaxle from the X-Pipe and exhaust cut outs. The heat shield was...

I've bought a bunch of headlights on eBay. To check the fit, I cover the lens with packing tape, wax it and then do a thin fiberglass layup. I had high hopes with several when I laid the shell on the body because the fit was good. However, I bonded two steel plates on top of the shell so that I...

Brian, I'm traveling and can't measure and even I were it's a little tricky to be precise when installed. Looking at some old notes, I have the total length as 32.4", but don't hold me to that. I have a street and I needed to cut a notch in the "bumper" below the license plate to clear the part...

The Albins ST6-M is a really nice transaxle that works well in a SL-C. It has been used on multiple endurance SL-Cs and I have one in my car. With respect to fitting it in a SL-C: (1) It's compact and lightweight... diminutive compared to the Ricardo that it replaced. (2) The CV angle is much...

Joel, I plan to use both ZircoFlex and ZircoForm for heatshields. I had spoken with SwainTech a long time ago. Their solution will retain heat much better than the smooth ceramic coatings because it's a thicker coat of actual ceramic material rather that a paint with ceramic flakes in it. That...

I agree that ceramic coating will make a difference. I've recently discovered Zircotec's ThermoHold solution. It's applied with robotic plasma-spray robotic system, baked at 550°C (1,022°F) and is suitable for applications of up to 1,400°C (2,550°F). This results in a thicker 0.3mm (0.012″)...

Howard, I'm happy to have the love! The exhaust cutouts now flow from the expansion cones that precede the catalytic converters to the X-pipe. There is very little space between the transverse chassis billet member and the bottom of the transaxle, so I used 2.5” tube. Given that the rest of the...
