my dyno run is also SAE corrected but defenately was not my intension to mislead
someone

i thought that sae is for compensate the different conditions

i read the wiki and somewere it says :

SAE net ratings, while more accurate than gross ratings, still represent the engine's power at the flywheel. Contrary to some reports, it does not measure power at the drive wheels.

that makes sence for my case.
iam not 414whp that i thought, but 380 lets say.

but what comfuses me is the following.
more than 10 s2000 dynoed on the same dyno as me .
all was sae corrected and the most powerfull 1 stage n/a was 220 axle power PS
a completely stock s2k was 202 axle power PS.
that means that the guy with 202 is only 170whp

What comfuses me is that all SAE corrected dynos gave the correct results of what i thing is the real whp on a stock s2k

 

I just got tuned last night (well, I picked it up last night).

I got 389 hp @ 10psi (creeped up to 10 just before 8400 rpm's), 239 tq.

Inline kit w/35r upgrade, 675 inj., AEM 1052, 38mm WG, Ultimate Race dual 3" exhaust, Ironman clutch and 9.5lbs flywheel, stock motor(no HG). I used the Spectre intake to move the filter in front of the oil filter relocation kit. The shop was amazed, we were expecting around 330-340, it's a safe tune, afr's are all good. I have a dyno sheet in my pocket but have no way to post it.

That was on a Dynojet.

 

that's a 10sec pass, got any videos? 1.7 60ft that's nice!!! the best i ever got was a 2.27 60ft you must have the r200 diff

 

vortec .. 4 inch pulley .. inline pro head gasket . aem computer ..

 

iam quoting this again because i didnt got any answers - opinions about what stena
stated.

my tuner told me the following :

a dynapack (that is my case) works with the same way that bench dynos work.
thats why with a dynapack the only options you have is sae or din correction.
dynapack measures power to wheels and not flywheel.
you need a bench dyno to measure power @ flywheel.

SAE is a correction that compensates the differences in humidity, temperature and
barometric pressure . nothing more and nothing less .

so from my point of view , i believe that is NOT a good idea to POST UNCORRECTED graphs because it would make a big difference if you dyno during a very cold day or a very hot day.

after all, the numbers that n/a s2k's have on this dyno (SAE corrected) proves
that we are talking about whp.

 

In any case.
I aam not saying anything bad but the Dyno sheets Tell it all.
Look at the one above.
It says Flywheel Torque SAE and Flywheel Horsepower
I cant say anything to that since the dyno says Flywheel.

Also I have been looking at your dyno also.
See where you have to choose a Axle Y (right) - it says AXLE power..see if you can choose Wheel power there. Or if Axle means Wheel power.?
If you can play with your tuners Mouse than check those options and what options will it give.

 

It says flywheel horsepower on the printout but unless the TCF (total correction factor) is input it will read rear wheel hp. In the above example the TCF is 1.0 so no adjustment to make flywheel horsepower. Adding a TCF would throw another variable of drive train loss into the equation and that would only be a guess.

 

Wouldn't it be rear "hub" hp?

I do, however, remember why I do not venture in here anymore.

 

Just saw the neat spreadsheet for the first time. I see you all have my old numbers listed. Final numbers were 398 rwhp/228lbs-ft on Inline's DynoJet. Pulley was 3" and header was Rick's. Date would've been March/April '06. I blew the head gasket on the way to the Dragon that year and scrapped the whole thing in favor of a 2.5L stroker.

 

hi skip,Yup its your pulley all right but its the 3.25"
Been hitting nearly 15 psi on cold weather with it.
thanks.
