TTAC Commentator Nate writes:I’m working on a 1979 Dodge D200 with 360CID V8 4BBL carbureted engine, automatic trans, A.I.R. pump, EGR valve, and charcoal canister for the fuel tank hydrocarbons. The underhood factory decal says “California Medium Duty Emissions” and it has no catalytic converter from new. So here’s my situation:Read more
- All hoses, pipes etc. are there and all valves etc. are working .
- The A.I.R. pump works but the diverter valve has failed (vacuum diaphragm leaks) and is in the open position so it’s always blowing fresh air into the exhaust manifolds.

- THX1136 According to carbrain.com the cost for catalytic converter 'repair' is between $945 and $2475. They claim the converter cost itself can be up to $2250. Figuring $880 a unit doesn't seem too far out of line if the carbrain info is accurate. Wonder if gas theft is still going strong on the west coast also?
- KOKing I'm not sure what to make of the small commercial van market in the US. There are a fair number of Transit Connects and ProMasterCitys, but Nissan/Chevy dumped the NV200 even though they seemed to sell well (though I guess Nissan decided to get out of the commercial space entirely), and I don't think Stellrysler ever bothered C/V-ing the Pacifica.
- SCE to AUX "a future in which V8-powered muscle cars duke it out with EVs for track superiority"That's been happening for years on drag strips, and now EVs are listed in the top Nurburgring lap times.I find EV racing very boring to watch, and the lack of sound kills the experience. I can't imagine ever watching a 500-mile EV race such as Daytona or Indy, even if the tech or the rules allow such a race to happen.As for owning an electric muscle car, they already exist... but I've never owned a muscle car, don't want one, and can't afford one anyway. For me, it's a moot question.
- MaintenanceCosts I don't and realistically won't drive on track, but I think the performance characteristics of EV powertrains are just plain superior on the street. You get quicker response, finer control over the throttle, no possibility of being out of the powerband and needing a time-consuming shift, more capability in the speed range where you actually drive, and less brake heat. The only "problem" (and there are many situations where it's a plus, not a problem) is the lack of noise.
- JMII After tracking two cars (a 350Z and a C7) I can't imagine tracking an EV because so much of your "feeling" of driving comes from sound. That said you might be able to detect grip levels better as tire sounds could be heard easier without the roar of the engine and exhaust. However I change gears based mostly on sound so even an automatic (like a C8) that would be a disappointment on track. Hearing an engine roar is too important to the overall experience: so tracking an EV? No thanks!I've driven an electric go-kart around a track as my only point of reference and its weird. It sort of works because a kart is so small and doesn't require shifting plus you still hear the "engine" whirring behind you. The sensation is like driving cordless drill, so there is some sense of torque being applied. You adapt pretty quickly but it just seems so wrong. With a standard ICE car, even a fast one, RPMs raise and fall with each shift so there is time to process the wonderful sounds and they give you a great sense of the mechanical engine bits working to propel you.I feel track toys will always be ICE powered, similar to how people still enjoy sailing or horseback riding as "sports" despite both forms of transportation being replaced by superior technology. I assume niche companies will continue to build and maintain ICE vehicles. In the future you'll have to take your grand-kids to the local track to explain that cars were once glorious, smoke spewing, noisy things. The smells and the sounds are unique to racing so they need to stay that way. Often a car goes by while your in the pits and you can identify it by sound alone... I would hate to lose that.
