Supra Passed Smog "With Flying Colors"

Started this post last night, so what's below is from Sunday......

Took her out for about 2-1/2 hours today and put about 70 miles on her. Even got about 30 minutes of 75MPH highway time just to shake things out.

It's definitely down on power at 5000' compared to "sea level" in Long Beach, so I'm thinking of ways to free up some horsepower. In particular, the engine-driven clutch fan is notorious for sucking up to 18 HP at 6500 RPM! No, I don't drive around at 6500 RPM, but I do shift up there when I'm "In The Mood". Replacing the Old Skool engine-driven fan with thermostatically-controlled electric fans is crazy easy to do on these cars. If you don't want to go the aftermarket route, there are some Ford fans that bolt right in, and they  look like they came from Toyota! Plus, the clutch units on the OEM Toyota fan are know for failing catastrophically, allowing the sharp, spinning fan blades to violently contact the radiator.

Not pretty....

If she passes smog on Monday, I'm good for five years, so the Air Intake Pipe I bought from good old George at Raptor Racing will go on. This eliminates 3 molded, somewhat flexible rubber air couplings, the OEM "Silencer" in the intake tract, and the constricted, molded plastic air assembly that runs across the cam covers, and replaces it all with a mandrel-bent, ceramic-coated, aluminum tube. These are proven to be worth 8~10 HP at the rear wheels, as measured on a reputable chassis dyno. The Electronic Fuel Injection system has more than enough latitude to compensate for this, AND a hi-flow exhaust, AND a cold-air intake (outside air) for the air cleaner, AND a header, AND....that's about it, folks. Hey, it's a 1985 EFI system, has one "narrow band" (basically ON/OFF for RICH/LEAN) Oxygen sensor, and a "spring-loaded pot with a flapper valve" for an Air/Fuel Meter!

Quite primitive compared to the EFI systems of the late 2010's, but flexible enough to properly support the air flow needs of lightly modified engine.

Anyway.....the electric fan(s) and air intake tube are a gimmie; I already have the tube kit, and the fans are available at Rock Auto. Just have to go back to the forum and see what I need to buy.

This Is From Today....

Yep, she passed. HC, CO, and NOx were all less than half of the allowable amounts. The staff at Air Care Colorado were surprised to see a 33 year old Japanese car in such good condition, as these cars have a remarkable tendency to dissolve before your eyes. The younger Techs were asking all kinds of questions about it, and I was happy to answer them.

I took her out for a good hour to get fully warmed up, including about 25 minutes on the highway up to Wellington and back.

There was NO line at the emissions testing place, and they got me in, tested, VIN verified, and out the door in about 30 minutes.

Not quite so rosy at the Courthouse, though. When I called my insurance company, Hagerty, back when we first got here, they told me they'd rewrite the policy after we had a residence, and the car was registered in Colorado. The DMV told me I can't register the car unless it has Proof of Insurance in Colorado. The POI card Hagerty just recently sent me is a "California" POI, and Colorado will not accept it.

Catch 22!!

So I went ahead and applied for the change of title, and came home a bit dejected at how to figure this out. I called Hagerty as soon as I got back home, and it turns out I misunderstood the first Hagerty agent I talked to. The agent I talked to today verified all my information, and sent the policy over to the Underwriter's for the required changes.

Everything went through, and I now have the required Colorado-specific documents.

SO.....back to the Larimer County Clerk's office in the courthouse tomorrow where I can finish the process of getting the car registered as a "Collector Vehicle", and duck the smog test for 5 years.

Both times I've been to the Courthouse have been pleasant, and the employees helpful. Both times I waited less than 15 minutes after I logged in at the kiosk, and so far it's been painless.

    1. Yup, the most stressful part of getting her out here and registered has passed.

      I was pretty freaked about it not passing, but from the numbers, it sailed right through!

    1. Yes!

      Jim bows head gives silent thanks.....

  3. Of course she passed, she's as happy as you are to be out of Cali. (plus, she likes you).
    Isn't it wonderful not to have to put up with all the crap that they put one thru here.

    1. Yeah, she's kind of like my "Loyal Horse". I try and take good care of her, and she reciprocates!


Keep it civil, please....
