    I have been building my dyno database for a few years now.
    I believe it to be pretty accurate. I have each kind of car separated by year and model and the averages that should be the same are very close.
    A few examples -

    02 WS6 - 313 hp
    01 WS6 - 315 hp
    00 WS6 - 311 hp
    02 SS - 313 hp
    01 SS - 315hp
    00 SS - 311hp
    02 Firehawk - 316hp
    02 Z28 - 307hp
    01 Z28 - 307hp
    02 TA - 308hp
    etc..
    All of these cars average around 330 torque.
    do u have much info on a 99 WS6 and what they usually dyno at?

    I don't have as large sample size for '99 as I fo for the 01-02's but from what I do have so far, they average about 306hp / 320 Tq. WIth Manual Transmission.

    The larger the sample size, the more accurate the numbers but, the less variance there will be in the average each time I add another car.

    When I had only ten 02-04 Z06 Corvette's, the average was 352 hp. Now I have sixty-six 02-04 Z06s and the average is 353hp to the wheels. All those extra cars did not really have an impact on the final average.

    Also, it seems the 05-06 LS2 GTO may be little overrated. They average 339hp/339tq while the Corvette, with the LS2 averages 349hp/347tq.

    The 2004 LS1 GTO averages 302hp / 323 Tq while the Corvette with the same engine averages 305hp / 325Tq.

    also just to clarify..i believe Darth...just not about the build tolerances being very small

    I guess the term 'small' is relative. What seems small to me may seem large to someone else.

    It is a fact that production techniques have improved a lot over the years and engine components are made with a lot more precision than they were in the past. The build tolerances for an LS1 are a lot tighter than they were for the original smallblock.

    I found a statetment from Ford about the 5.0. They stated that the statistical range in output for the 5.0 was 203hp to 222hp. (203 being a turd and 222 a factory freak)
    I think that is pretty good. That shows plus or minus 4.5% from the median engine, which I guess would be a 9% tolerance from the weakest to the strongest.
    There is no doubt the LS1 is better than this. How much better, I'm not sure. My RWHP dyno numbers vary almost the same percentage as Ford's claim for the 5.0, but that is with the added factor of dyno variance.

    We will never be 100% sure. All we can do is make the best use of the information available to us. Each time the numbers add up to what I expect, I gain more confidence that my calculations are accurate.

    true. i actually herd that the gm ls1 has the tightest engine tolerences from them.

    99 - 04 GT -------231 / 269
    2001 Bullit ------- 235 / 275
    99 - 01 Cobra --- 274 / 281 (I saw no real difference with pre-fix 99's)
    96 - 98 Cobra ----262 / 272
    94 - 95 Cobra --- 220 / 265 (Small sample size)
    03 / 04 Cobra --- 366 / 361

    01-04 Lightning - 351 / 424
    03 / 04 Mach I -- 275 / 296 (I know they were rated different but there was only a 2hp difference to the wheels so I stuck them together.)

    magnacharger has one, you have to cut the inside of the cowl out a bit but they make a kit for fbods.

    If you're counting your pennies..or in this case hp..5-10hp on a 300+ hp car won't win you a race.

    Unless you're adding 20rwhp it makes no difference. Shut up and drive not count every last .05 of a hp your car may have over another persons.

    The problem is some people are insisting the WS6 puts down the exact same power as a non WS6. This is not true.

    Does it matter that the WS6 makes a few more HP? No, it does not. It will not make a difference in a race. Some of us just want to make sure people recieve a truthfull answer if they ask what the difference is between a WS6 and a non WS6.

    Oh i completely agree, no question about it.

    I was gearing my comments more towards the type of people who debate the gains which is why I said 5-10 is nothing...lol..it's an AIR FILTER, lol.

    5-10 RWHP can be a tenth. So yeah...it can make a difference.

    If your into racing then every single hp makes a differance. I watch race cars on the dyno day after day and these drivers worry about oil temp because it makes enough of a differance. Also along with the hp gain from a better air filter you get better gas milage and anything you do to make your engine breath better is good and every little thing adds up.

    a 10 h.p difference between two likewise cars isnt going to make the one with more h.p win.

    I have NEVER seen anyone claim that 5-10-20HP makes up for a shitty driver, or claim that that small amount of difference GUARANTEES a win to the stronger car. But if EVERYTHING ELSE is the same between two cars (driver skill, gearing, traction, WEIGHT, and aerodynamics, the car with higher HP has an advantage and is much more likely to be faster. If you don't think that is true, they why would YOU bother with that small amount of gain from a cat-back, or CAI, or even brag about your RWHP in your sig??

    when doing a catback, most guys do it for sound and a bonus is the h.p gain.
    i did a catback knowing that sooner or later it would lead into headers.
    gains from long tube headers on any muscle car will be atleast 20 rwhp and 20 hp is something that you can begin to feel and get better track results.
    10 hp isnt gonna change much time wise nor seat of the pants.
    im my case from day 1, modding was all leading up to a cam.
    everything else was a supporting mod.
