Torquer dyno numbers... (copy from NW members forum)
Here it is! For some reason I couldn't get both HP/TQ and A/F ratio on the same graph, so I did two seperate ones. Not too bad for not really being tuned yet. I thought the TQ was a little low for this cam, but I'm sure the proper tune will bring it up. And damn, I knew this thing was loud, but when I heard WOT from outside the car I almost **** myself! I'm really gonna have to watch how I drive, cause you could probably hear this thing a mile off! Tell me what you guys think!

Warmed up and idled at like 900-950. Pretty much un-driveable, as it would constantly stall out when I let off the gas in neutral, and the surging was pretty bad. Typical large cam stuff. I played with the TB set screw, and got it to where it would hunt for idle, but rarely ever stall out. Hot starts were also a bitch. Very driveable, but a pain sometimes. Tune still needs work, but hot starts are no problem any more, and the idle is stable and very lopey at 850 RPM. I also backed the TB set screw almost all the way back to stock, and drilled the TB, which is working alot better.Here is the scanned dyno sheet of the original run:

question, if u adjust the tb screw or drill out the tb hole to make it idle until u get ur tune, wont u have to find a way to put that back to origonal size after u get ur tune? or is this really not even a factor? was jw.
anyways congrats on the good #'s.. i hope the 233/239 im looking at will make good down low tq like ur cam does!

dude your numbers seem right on then...i'm going a little bit more on the mods with a mild job on the ports a lid u/d pulley and milling the heads just a tad...unfortunately tsp didnt have any torquers so i went ahead with the 233/239
good numbers...your car is strong...i took a ride with matt and it sounds like a beast and pulls hard...too bad the roads were wet.

Yet another item on the list for when I pick up HPTuner.

i just cant decide what would run faster with only a 3000 stall, which i may got 3500 later, a 3.73 rear, just dunno which is best n/a, or n2o, which one will drive on the street better, i assume the lope on both is nasty and prolly cant tell much difference there.
