I investigated the wiring and lines. It’s all hooked up correctly. We may be down to a bad hub sensor, sensor converter, or DSC ecu. Though someone posted something interesting on the facebook group that mentioned an intermittent lockup issue. They were having the battery voltage drop enough when the ABS pump went through the…
Another autocross today. No issues with the car. Valve train and new O2 seem to be working out. Oh I didn’t mention that in the last update. The cheap no-name brand O2 I got off amazon were running terribly. +45% fuel trims. I put new Denso units in while I was doing the valves. Back…
Back to Autobahn today. Today was really frustrating. Session 1 was great. Ran a 1:37.50, but I forgot to put a memory card in my camera. :\ I was running in advanced group and very little interaction with traffic. Session 2 my car was badly misfiring. I went back to the paddock after 2 laps….
theruleslawyer said: Burning some oil in the braking zone. The engine is probably under a ton of vaccum and sucking some oil in. Reportedly it clears right up out of the turn, and doesn’t impact a high G turn alone. I need to check the oil catch can. Maybe its full? Brake has inconsistent feel….
I went to my first track day with the c5 this weekend. I've been to autobahn south enough times that I'm pretty familiar with the line. My previous best in the F82 M4 was 1:38.21. First day out in the new c5 I ran 1:37.94. Down well over 100hp and losing time with shifts vs…
nsogiba said: In reply to theruleslawyer : I had the same issue with the exhaust bolts on my C5. Just ended up doing headers from Huron Speed (don’t know if they still offer that system). Maybe just torch/drill out those studs and replace? I get not wanting to throw more money at the problem. Yah….
Last weekend I tackled the steering rack. What a PITA that was. I’d like to strangle the engineer who made me drop the subframe to get the rack out and only allow about 1/32nd of a turn on the PS lines from the pump. Extra fun was the new rack didn’t come centered. So when…
Never fixed a rack but they’re not difficult to remove. You might want to upgrade the rack mounting bushing while you’re in there, it’s cheap and easy. https://www.dougrippie.com/drm-steering-rack-bushings — nsogiba, Grassroots Motorsports forum, March 6, 2024 In reply to nsogiba : I hear it’s just a lot of work. I need to disassemble the front…
New discovery day. I finally got under the car. Springs are the base ones per the casting numbers 22146484/22146483 Sway bars appear to be c6 z51 models. 25.1mm rear 31mm front 10339124 Shocks look like they are stock c6 z06 shocks 10313647 While I was in there I nudged the front ride height up with…
