BTW -- Notice the nice smooth curves for the gas flow -- NOT!
The top 3 into 1 pieces have the outer 2 cylinders doing a 30 MPH right turn at 600 MPH.
And the lower 'A' pipe is worse -- the exhaust gas is making a hairpin U-Turn!!!
Ouch!

Our cars supposedly put out 260hp at the crank. From numerous dynos seen on the board...we only put out about 200hp (plus-minus a couple hp). I believe it was calculated that we loose 23% of the power by the time it gets to the wheels.
The headers have dyno'd at 30hp to the wheels which equals about 40hp at the crank.
Thus with headers...you should be pushing about 300hp (nice number). If I am mistaken in my calculations......please let me know.
By the way.....Sweet F#CK'IN headers.

I starting thinking about this and have the following points to make:
1. 20% and 23% have been proposed as the "loss" in the drive train from the flywheel to the front wheels.
2. Some of this loss is due to accessories and other "items" that do not vary the amount of HP drain they put on the engine with increased power.
3. Oil shearing and other factors may well be quasi-linear, but I would expect that some frictional losses are not linear, but have 2nd and 3rd order terms. If these are infinitesimals, then they are not of a great concern for the calcs going on here. But, I'm not so sure that I really know this.
4. Back calculations like these are like "trick" questions given on tests. The answer and solution look easy at first, but upon further examination, they do not turn out that way.
(It's late and I have to get up way early, so I'll see if I can toss something together here that makes more sense...)
Acura says that the flywheel HP is 260HP, if someone adds the headers with their 24 HP net gain, and then factors in the 20-23%, the "apparent" flywheel hp seems to be in the range of 290HP.
However, without measuring at least 2 to 3 increasing flywheel HPs with corresponding wheel HPs, there is an implicit assumption of perfect linear scaling and non-fixed frictional losses. I have serious doubts about this being so. There is also the issue of the non-fixed frictional losses being non-linear with increasing load. Without at least 2 or 3 modifications with the above mentioned flywheel and front wheel comparisons, we are all having a big circle jerk.
It is good to get a "rough" idea, but we could actually be getting flywheel readings that are too high or too low.
I hope some of you will think about what I have said for a bit, before jumping on me. I've been thinking about this for a while, and I've presented some calcs too -- so I'm implicating myself too.
A more that $0.02 production.

Two words: you bastard! I'm so jealous. Hey you want to race Maddogtx's M3 this weekend at the meet? If you beat him, I think I have some money to spend. BTW, where did you get it installed at?

How good is the grade of stainless steel used? Will the headers hold up for say 7-10 years? Anyone have re-torquing issues?

Next time you're in a car with a lightened flywheel, let me know how your take-off's are... You may dump the clutch a few times.
I guess, I'll have to get out some more html font tags with size attributes and put them in list format at the bottom for footnotes, references, and explanations...

I gotta question...if acura rates the cl-s motor at 260 HP at the crank, does everyone else do this too, or have to do this? (everyone meaning every other car manufacturer) Or do some post HP at the wheels for advertising their cars?
Or was it a misleading thing like a 32" tv that only has 29" viewable?

Most manufacturer's rate the HP at the crank. Depending on other factors, the HP at the driven wheels can vary over a large range.
Example -- put on some light wheels, and go back to get a dyno done on a Dynojet dyno, and it looks like there is more front (or rear) wheel HP. They spin-up a big drum. The faster the drum spins-up, the more power it makes (I've oversimplified this...). So, put on lighter wheels, more HP shows up. (Does the car have more power -- no. Will accelerate faster -- yes)
If you have a manual vs. a "conventional" automatic transmission, more power will end up at the driven wheels.
So, if the car comes in 2-flavors (Auto and Manual) -- what should the car maker report for hp?
If the car comes with light alloy wheels -- what should the car maker report for HP?
More than once, I have given "complicated" answers and people were disturbed and confused. So, isn't it possible that "simple" figures are better for "most" people.
If someone wants to know more they can pick up a magazine. Want to know even more -- look for a web site (like this one). Really in to it, drive the car and compare it to others.
BTW -- with flat screen monitors they generally report the "visible" size (with a note that visible is the same as the rated size). With CRT displays and TV (16:9 HDTV and 4:3 NTSC), the makers just give you this "rough" diagonal number.
