I found a shop, not exactely local, about 85 miles away that was sympathetic to my needs. He said as long as he didn't have customers waiting for an emmisions test, I would be able to use the equipment in diagnostic mode with a tech present to do a little tuning and try to get her to pass.

So I spent ~3 hrs of the last few days welding in a new center section for my exhaust that consisted of a Magnaflow hi-flow cat and some other bits. I bought the one with the air injection port already welded so when I have to go back with a working air-pump, it's won't require me to take the exhaust off and weld stuff in, just plumb it up. I didn't replace the precilencer that I have now, I just built an entire new center section. The way my exhuast is set up, there is a flex pipe and the end of the DP with a 3" V-Band welded on. On the other side of the V-Band is a MagnaFlow 3" in 2x 2.5" out and a few bends heading off to the rear cans. Right around the axles there is a second V-Band on each side that seperates the mufflers from the presilencer or cat. I built a new section with the cat between the V-Bands. When I originally bought the pre-silencer, MagnaFlow offered the same case in with a cat installed. They have since stopped offering that so I had to buy a 3"-3" hi-flow cat and a 2x 2.5" - 3" Merge Collector as well as a few other pieces of piping. Either way all I need is my 7/16" subby racheting wrench and 5 minutes and I can swap the center sections out.

True to form, today is the deadline so I went up late this morning The tech backed the car in, no door dings this time, off to a good start.... although he did stall it FOUR times even after I warned him it was a grabby twin disc clutch, "eh, we deal with those all the time." It's a Rustang/Vette shop primarily. So we started her on the rollers with his foot on the gas and me working the MoTeC. Got her into 3rd gear, as opposed to first and started the sniffer. Ended up pulling about 20% fuel from 1500-2250rpms and right around the 40-60% effiecency mark (roughly the same in kpa) to acheive a L of ~.98. I generally have her running ~.9-.92 in that range.

Someone else showed for a test so we pulled my car out, I was done anyway, pulled a honduh in for the CT Emmisions test and that failed then pulled my car back in, again no door dings but one stall.

Here's what happened next -



This was done on regular 93 oct, Idemitsu PREMIX IN the tank mixed at about 1/2 oz/gal AND the OMP working as well. This is more oil than what is recc'd but I was doing some SEVERE back road jaunts yesterday with a few local rotorheads so I added a little extra lube love. No alcohol tricks, no crazy advanced timing, no pumping cubic acres of air into the exhaust, no air pump at all and BOTH tail-pipes being sniffed and she still passed. Who says you can't have a street/emmisions legal 400+ RWHP rotary???

Oh, and the engine survived this time with all her sideseals intack Coolant hit 188* and oil hit 170*, hood open, no fans though, but there was a garden hose present that I noticed JIC.
