stillen sc
My 350 5 AT made 272 at the wheels with a stage 2 stillen.
With a stage 3 pulley it make 288 RWHP and 326 Lb of torque. the difference between stage 2 and stage 3 is like night and day. Car ran 13.84 at the track and will post next week after my next track day (stage 2) stock tires.
Have changed the pumpkin to a 6 mt. and it should run high 12.s now with the stage 3 pulley.

Stillens numbers are no different than any other numbers are estimated and advertised at the crank unless otherwise specified

Some people get caught up in the horsepower talk, but forget about torque.
This is why I never wanted to go with test pipes. I refuse to do anything to lose low end power.
If I'm going to gain horsepower with a mod, but lose torque.....I won't do that mod.
All this to say, I wish they would post torque numbers too.

Low end torque is good for lugging around in traffic which unfortunitly we spend most of our time doing.

You guys quoting all of these 25%+ "paracitic losses" on 5AT's, are NUTS-O!
For some interesting reading with real world data, check this thread... Post #10 is where esemes takes my "conversion factors" and recipricates them into a drivetrain percentage loss and in post #30 zimbo adds yet a bit more logic which I should have initially made more clear in my initial write up...

Where do you live?....I'm in Southern CA and just made a deposit for Miller Nissan of Van Nuys for Stillen stage 2 kit

That's a great mentality, if you want to be slow.
^^ Huh??? ^^
Do you realize that horsepower is a *function* of torque? HP = ( torque * rpms ) / 5252.
Stock, our engine's torque peaks at roughly 4800 rpms, while the horsepower peaks at 6300, correct? The only reason horsepower increases beyond the torque peak is because the rpms increase more quickly than the torque drops. So, to increase higher-end power, one actually increases the engine's torque output at higher rpms.

straight line, yes...but throw some turns in there, and it's a different story

all i was getting at was using a manual gives the driver greater control of when he/she wants to shift. while the auto doesn't car what kind of "lateral g forces" you are feeling, an auto tranny doesn't really know when you're going into a turn, and when you're comin' out of it.
so i guess this is going to turn into another one of those internet arguments where "i'm right, and you're wrong, and blah blah blah ***** blah blah!" great....

Real Racers use F-1 or DSG. Manuals are actually obsolete. I love them for their feel and all the perceived control as I've owned 4 or 5, but obsolete by current standards they in FACT are.
As for the AT knowing that there's a curve coming, it's this new thing called manumatic. I tell it when it's coming by downshifting more faster and more precisely than any manual that is not computer controlled.
Not an argument unless you want it to become one. I'm simply posting my objection to your lack of information and knowledge in posting about the current generation of trannys. In fact you probably haven't seen ChicagoX's video of him in his AT X owning several vettes, GTO's and other sports cars that go faster than him in a straight line and have manuals. He must have got one of auto's that has ESP..... or he shifted his manumatic like every other auto G owner.
Oh and speaking of REAL, real men don't name their cars!

anyway, i don't know who ChicagoX is, so i won't doubt what you say about his "owning."
and what exaclty is the current standard? isn't manumatic just a market scheme anyway? i mean, it kind of takes the "automatic" out of it all if you still have to fiddle with something. i mean, it's not true F-1 paddle shifting or the real sequential shifting of the WRC rally cars. the paddle shift still is a kind of manual transmission, though not the typical "stick" by any means. the new lancer is going to use a manual...it's the ricardo/mmsp 5spd....maybe you've heard of it. here's a quote:
"The transmission also reflects MMSP's new strategy and has nothing in common with the four-wheel-drive systems used on previous Lancers. The 2004 car will use a transversely mounted five-speed gearbox supplied by Ricardo. The gearchange will be manual and all three differentials will be passive, an epicyclic centre differential splitting torque front to rear. The front and rear differentials will also operate on mechanical principles."
i mean, if you're going to talk about those trannies, they're more expensive than our cars, that's for sure. i would hardly call that the standard. besides, any type of continuously variable transmission is illegal by FIA regulations. i guess that could be considered a standard, too......
i'm not looking for an argument, but don't tell me what i know and what i don't....with having over 2000 posts, you should know how it works around here by now.

Exactly. High horsepower numbers are an indication of high-rpm torque, which is exactly what you want. The more high-rpm torque you have, the more you can take advantage of gearing to maximize your net force at the ground accelerating the car (you can stay in a given gear longer before the next gear ends up generating more net ground force).
With higher mid-range peak torque numbers, the car will actually accelerate more quickly in a given gear in the mid-range (obviously) and feel faster. But if you end up winding out the gear and "racing" more more than that instant in the mid-range, you'll wish you hadn't traded that high-rpm torque for mid-range torque.
