I replaced all the hydraulic lines (brake and clutch) with nickel/copper lines. I had been using flex lines throughout the car due to problems making good flares on steel hard lines. I bought a new flaring tool that makes really nice inverted flares. With the new tool and the copper line, I had no leaks on the first try. I installed Kevlar flex lines at each wheel. I installed C6 Corvette parking brake shoes in the rear so when the car breaks down I can secure it from rolling. Due to mounting constraints, the brake lever is on the left … Continue reading Update 7/16/21

The new idle valve is working. After adjustments to the fuel injection software the car starts and idles without having to touch the pedal. I fixed several coolant leaks. There is an oil leak from the righthand valve cover which is dripping on the exhaust manifold and making some smoke. The catch can is also venting vapor. I tried out the auto tune feature of TunerStudio which makes on the fly adjustments to the VE table. The feature doesn’t really work without the wideband O2 sensors unless the mixture is already very close. Without any load on the engine I … Continue reading Update 6/9/21

After all the changes and rewiring, the engine runs again. I’ve got a few leaks to fix and the engine is producing some smoke as it burns off surface residue. The silicone exhaust wrap spray is curing which is causing most of the smoke in the video. I warmed up the engine to about 160 degrees before shutting it off. I think it’s still running very rich. There is a strange whistle coming from the intake that varies by rpm. It might be coming from air passing through the idle valve which is currently disconnected while I check timing and … Continue reading Update 5/24/21

Wiring the car I’m installing a 4 circuit fuse/relay box in the front near the fuel tank for the fuel pump, radiator fans and horns. Inside the car I have a 10 circuit relay box and I’m using the original engine relay box in the rear. All power goes through the cutoff switch and two circuit breakers on the dash—one for the engine and one for everything else. I’m making a new switch panel to replace the one shown in the image below. Continue reading Update 11/11/20

Wheel stud upgrade The car was using different wheel stud sizes between the front and rear hubs. The front has Wilwood hubs with 1/2-20 studs and the rear has Chevrolet bolt on hubs for the Corvette rear spindles. The OEM stud size in the rear was 12-1.5mm. I purchased two sets of ARP 1/2-20 conversion studs for the C5 Corvette and installed those in the rear hubs. I took the opportunity to install Timken hubs which use tapered roller bearings instead of ball bearings. Installation wasn’t too difficult using a tie rod press to pop out the original studs, a … Continue reading Update 10/27/20
