  1. Since we had rare (for Feb) dry/warm couple days I was able to roll the car out and slap some paint on some bare metal/rusty spots in the headlight/radiator area and new hood pin mounts. Also signed up for the Charlotte race.
  2. Slightly hotter cams installed (claimed), trying to get an appt with a tuner. Ordered a new water temp switch and M14-1/8"NPT adapter so I can swap locations for our WT/WP warning light senders. Also finally adding the OP warning light switch. Ordered a different fluid level switch (buna) to see if it floats better (thanks Huggy!). I think we're having issues with swirl in the surge tank causing the SS float to stick down (light stays on). Hoping a bit more buoyancy will help. Working on proper radiator inlet ducting. Just need to fab up some brackets to secure it and then
  3. Oh, I agree with that as well. But even with proper fasteners torqued to spec ours backed off anyway. YMMV, but I'd still recommend an additional fail safe such as safety wire, tabs, etc.
  4. HANS. Because this^^. Not just IMSA, but all pro motorsports. Grojean was wearing a HANS. McDowell was wearing a HANS.
  5. Ours is on Lexan, but we've not tested it yet. Its my understanding that fogging is far less of an issue on polycarbonate, but again, we haven't had any fogging yet to determine either way. The main issue I had was applying it to the lexan and then installing the windshield afterward. I applied the grid with the window flat, but once installed/curved the grid wanted to lift off the window (and still does to some extent). I don't think it will dramatically effect the performance with some small sections not sticking down, but something to be mindful of when applying prior to ins
  6. They're "visible", but don't notice it on track since focus is way out in front of the car.
  7. Some sort of time penalty (1-2 min per tire?) for changing a tire seems the most reasonable. Or maybe as simple as a drive through penalty. If you add pit stop time, it might have to be added to the next stop since adding time during the tire change stop might be hard to manage. I don't know if we're still using kitchen timers or not (been a few years now). Tires will continue to evolve so I don't think banning specific tires or going to a spec tire is the right move. But I agree there should be some sort of discouragement for changing tires during a race. Tires are nearly alw
  8. This was along the lines of what I had in my head as the current rule definition around exhaust manifolds. Was hoping the '21 rules would provide clarity. @TimS No, they're definitely regular old cast iron on the VG engines. Not sure what came on the later VQs.
  9. I have some fun stuff laying around too
  10. I'm totally confused by your post. I never reference nylocks, or even nuts at all. I was referring to the fasteners that hold the flywheel to the crank. I've only done a few different clutch jobs in my life but I can honestly say I've never seen a nut used in any of them (flywheel or PP). But maybe its just been the makes I've worked on. Anyway, for clarity, something like this is what was recommended under the bolt heads that hold the flywheel to the crank:
  11. I work with a mechanical engineer that spent years designing racing clutches and flywheels for a major manufacturer. One of the issues he brought up with aluminum flywheels in a racing environment is the higher material expansion of aluminum over steel, which can lead to the flywheel bolts wanting to back out. He suggested using a steel flywheel shim under the bolt heads to help distribute the load on the flywheel.
  12. Nissan routed the pass side exhaust over the bellhousing and into the dr side manifold. This was done for turbocharging purposes, but left on/adapted to the NA car. The x-over pipe/flex joint is prone to failure, NLA (we're on our last good spare) and ran right next to the brake and clutch hard lines, so I'm not a fan of the setup. It certainly doesn't help exhaust flow, either. Installing the pathfinder manifolds (provided they clear on the Z) would theoretically allow me to remove the x-over pipe and route the exhaust out of both sides of the engine. I'm not aware of anyone doing it bef
  13. There was some brief talk about the interpretation of the rules regarding exhaust manifolds. I see they're included without penalty on swapped engines. The FPL, only lists "exhaust headers" as 25 pts. Is there a points penalty for using an OE cast-iron exhaust manifold from the exact same engine (no displacement difference), just from a different vehicle? I would like to reroute my exhaust, but I'm unsure how this would be interpreted and the BCCR doesn't offer any real answers on the subject. I know there was chatter about some GM guys using "wrong" manifolds so I was curious
