a cat is almost pointless on the rolling test, past about 2500 RPMS the cat really cant keep up very well, i would lean it out a little, propane may help you out, while your doing a tune i would get a sniffer "smog analyzer" in the tail pipe and watch your emission levels and it will help you determine if you were getting better or worse. also due to the age of the car the standards for it should be lower than if it were a new car.
i know when i did my last emissions test the car was running very rich due to a slight vac leak and IC pipe leak and a plugged EGR, i had 3 inch pipes and no cat and still passed,but barley. how do you like that powerhose rail by the way lol
Yah, I was hoping the car would be old enough to be exempt from the emissions portion of the inspection, but I'm still five years out on that one!
I didn't know you could find/buy a "sniffer - smog analyzer". I think the inspection shop empathizes with me, but I'm not sure they'll let me tune while it's on their inspection machine. Maybe they will, couldn't hurt to ask.
Yah, don't get me started on Jarrett Humphreys. The more my car is seen by people in the "Supra Circles" the more horror stories I hear about how Jarrett screwed me here or there. Some of it is pretty comical like the time Jarrett told me my car was in New Mexico when in fact a friend of mine saw it at Ross's shop here in Texas. This was before I knew who Ross was or that his shop even existed.
Some of it really isn't comical like the time he ordered a "new" HKS IC setup for me only for it to be the EXACT same HKS intercooler setup I bought for the car back in 1990! Jarrett stuck me with it and kept my $1400. Told me to deal with it or come pick up the car with a trailer as is unfinished. At that point I didn't have any choice but to see that he got the car finished.
BTW, anyone want to buy an almost brand new MKIII HKS Intercooler?!
I've learned that Jarrett is a habitual liar. I guess he can't help it...poor guy. He's a real piece of work, but what comes around goes around. Jarrett will "get his" sooner or later and I won't be shedding any tears for him.
Regarding the Powerhouse fuel rail I can't say if it's good or not as I don't have anything to really compare it to. I do know that I find small pools or puddles of fuel accumulating in-between the intake runners on a regular basis. Not something I'm real pleased with, but Ross and the guys at Dynosaur Performance will be seeing the car again end of this month or first of next. I'm sure they'll find where this fuel is coming from and fix it.
So...you've got me wondering now why you ask about the Powerhouse fuel rail. Are these things known for leaking and burning down cars or something!
Best,
Brad
