Working backwards through responses.

1994 Maxima GXE. I believe drag coefficient is around .31 and I think the CdA (drag coefficient x area) is 7.09...I forget what unit I used for area but whatever it was it puts my car slightly below average in aerodynamics (at least in the list of cars I've bothered trying to compile info for. Honda Insight being a 5.10, Mazda RX-7 (FD, 93-95) being 5.61, etc. This is of course stock and I am an inch or so lowered

I have already removed EGR. I have a 3" aluminum intake and 2.5" exhaust. I was also thinking some newer cars use cam phasing to increase overlap at low RPM to serve as basically EGR, so maybe some extra overlap wouldn't be that bad of thing? After all in Europe factory cams are 264/262 anyways.

example post from a 350Z forum
"It's not advisable to use aftermarket cams with the Rev-Up motor if you plan on going forced induction. Reason being that Nissan didn't install an EGR valve on the Rev-Up motor and instead uses the variable exhaust cam as the EGR valve. This means that there is alot of overlap anytime the cam is in EGR mode."

Now for Loren's post... My car doesn't give a rats ass how low it's revved. It has no AC compressor, no power steering pump, etc. Only things sapping my low end are the water pump, alternator and the torque converter (which I do want to remedy and soon). It spins tires on accident on the street...I chirped them just the other day in a Walmart parking lot at probably 1200rpm making a right turn under maybe 10% throttle. As you well know my car weighs about 2800lbs with me in it versus probably 3400 stock, so my torque to weight ratio is sky-high compared to stock. Though it doesn't really wake up till the 2Ks. My car doesn't struggle to do 60 @ 1800....my throttle plate is sooo close to closed that the intake manifold vacuum is at 19psi which I think is low for what my engine is capable of. I think if I could get it to 21 or so if it was tuned right. My idle is 19psi as well, I usually have around 12psi when I'm accelerating at a decent rate, 9psi when I'm accelerating decently but faster than anything else on the road.
