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...

Howard, thanks for the advice. I had a similar concern, but when I spoke to guys at Steve Morris Engines they told me that it wouldn't be an issue. They build engines from 900 to 4,500 HP (billet block) and have experience with these valve covers. According to them, if I have that much oil in...

I decided to locate the engine oil breather can aft of the engine to reduce the potential of fumes making their way into the cockpit. I wanted to use a Peterson Fluid System’s breather because it features a lightweight, high-quality spun aluminum canister, hand TIG welding, proper baffling, etc...

Colin, I didn't know that titanium could be anodized. I found lots of pictures of anodized titanium, but none of exhausts. Do you have any pictures/link of an anodized titanium exhaust? ---- The O2 sensor bungs and exhaust cutout tubes have been installed in the catalytic converter...

Howard's suggestions are spot on. A couple of points based on my 2016 car which might be different than yours. The brake and clutch lines that ran to the rear of the car were mounted to the 2" x 6" tube in the left side pod. All of the brake lines in the rear are mounted to the lower 2" x 2"...

Thanks for the feedback regarding how to treat the titanium. I’ve decided to remove the alpha case with Scotch-Brite pads and then let the heat cycles do what they will. In a previous post I designed brackets that mounted the heatshield to threaded bosses on the transaxle via vibration/heat...

Mesa and pnut ran into TractTive (TracTive Suspension – The Art of Suspension) at PRI a few weeks ago. TracTive offers an electronic semi-active damping system which has a 6-10ms response time. They seem to be an engineering-focused company (a good thing), so there isn't a lot of detailed...

In the last post regarding the exhaust the 3.5” titanium cat-back system was tacked. Since then, Abe has finished approximately 1,242” of titanium welds. I need to decide if I’m going to: Leave them as is Remove the alpha case with a Scotch-Brite pad Remove the alpha case with a Scotch-Brite...

Joel, Mine was different. In my experience the critical stuff like the welds, machining, general architecture, etc. are top notch, but the assembly to ship the car is extremely variable and depends on who did it and how rushed they were to push it out the door. For example, I had issues with my...

Howard, Good suggestions. I have used the method that you described above to install/deinstall the rear legs, but it doesn't work for me with the engine in because the Y-section collides with my headers. They're an equal-length, 180-degree cross under design and, like many exotics, they must be...

I’ve removed/installed the cage many times and it’s a pretty quick and easy process. However, it’s a royal pain in the ass to install the rod ends that connect the rear legs to the top of the rear hoop. It takes me longer to install those two bolts, than it does to install the other 14 bolts...

Hector, Fabricating hinges that are as aesthetically pleasing as the original hinges requires a fair amount of CNC. However, fabricating ones that are functionally equivalent is straightforward: (1) The pivot point must be as low (i.e., close to the splitter) as possible and in alignment with...

Bob, What state are you going to register it in? I had a cobra registered in NJ for 20 years, but I had an absolute nightmare registering it in MA. That process was 1000x more involved than Lee's import experience above.

The car was in H's shop and Fran pulled molds from either it or the sister car for the GT-R. Dave recently passed away. I never met him, but from everything that I've heard he was a world-class guy. RIP Dave. I hope that the car finds a good home.

Mason, Everything is plumbed in the car for a test, so I can't easily measure it now. The unit sticks out a lot further than the standard master cylinder. However, Allan installed my pedals where he does for everyone regardless of height (apparently he typically makes up the difference with the...

Joel, it's good that you can easily service the fuel sender. Note that your modification to the tank will change the custom calibration for the stock SL-C tank. I think you can send it to Centroid to have the calibration modified. Or you could remap the values elsewhere. In any event, you might...

I'm aware of several builders who have had units fail. One builder had it fail after one tank of E85 and the others were running standard gas for probably a couple of years. If you have a tub, you need to tear the car apart to replace it. It's primary benefit is that it's calibrated to the...

In a previous post, I discussed my plan to implement power brakes with a GEN1 Bosch iBooster, I fabricated a bracket to mount it and I machined the pedal box. The next step was to connect the brake pedal to the iBooster. Since the iBooster has only one input rod the front/rear brake bias will...

Frank, I did a lot of research when getting my Penske shocks to fit properly. I spoke with someone who gets paid a lot of money to tune progressive spring rates like the ones shown below. For my purposes, I have a main spring, a bump spring and a bump stop. Once I get the car on the track, I'll...
