i work at a local shop around here. today was a slow day and we decided to dyno my car after we had finished this turbo'd S2000 (463 whp). to make a long story short, my current mods are an Injen CAI and Tanabe SRM.

Wheel HP: 192

we did seven runs with her. first run yeilded 186 whp at 7400rpms and 192 at 7980.

flame all you want im scanning the dyno sheets tomarrow.

BTW: measured crank hp was 247.029 @ 7916.950rpms and 110mph. measured tq: 163.852 @ 7916.950 rpms and 110mph.

all runs were performed on our only dyno, a chassis dyno. pics of the shop will be taken to verify that it is indeed a chassis dyno.

There's no flaming needed, all dynos are different and produce different numbers. Yours just so happens to be 192. If you went to another dyno I bet you wont get the same numbers, it might be less it might be more. Dynos are a good tool to determine the amount of hp a mod does and not a good tool to show that your car is a freak or fast or powerful. It would be more interesting to see the change in hp your car gained from the two mods you have.
need proof? dynos dont lie. we ran the car numerous times on different calibration to simulate that of other dynos. 192WHP was the LOWEST record run except for the intial run of 186whp @7400rpms.

the manufacturer of the dyno is the oldest is the world. rank number one and used since the 1940s(this dyno is fairly new) to check for emissons. the dyno is a CLAYTON VTT ( Vitrual Test Track) and gives more than HP and TQ readings but also emissson readings, load reading, ect.

if you need anymorew proof than what i will provide tonite (dyno sheets) then i invite you to bring your car down for a few runs.

have a nice day.

secret mods? :laughing:

maybe u can temp remove ur mods and do a base line run and compare the gains... that way it'll keep your bored working day shorter:thumbsup:
yeh i can try to. i have to see what cars came in since wensday.

dont worry. you'll get plenty of flames around here. just as i'm quicker than most people here with hondata, you have more power with folks do with hondata or race header with other bolt-ons. whatever though. i'm fast thats all i care about :wavey:

haha. good attitude. i could care less either but i do like proving people wrong and seeing the expression on their faces.

Dude, I don't think you understand what anyone's point was in response to your dyno numbers.

You got a 192whp and 160+torque, good for you!

But the fact is, dyno's are only good for one thing: comparing mods and the gains you get for them.

192whp doesn't mean much of anything and you should know that...take it to the track and come back with a fist full of high 13 second slips and then it'll mean something. I mean, you should be able to hit that with 192whp, right? So, go do that and then your amazing numbers will actually mean something.
i didnt make 160 wheel torque. that was made at the crank. i really dont have an interest in the track but i guess i can make a run down there as soon as the rain lets up. the only problem is the closest track is an 1/8 miles track and the closest 1/4 track is moroso, which is about a 3 hour drive form here.

will wheel diameter have any affect on the HP numbers?

so if i went with a small diameter wheel and tires combo then would numbers be lower or higher?

You forgot to add JDM emblems (40 h.p.)
:p











j/k;)

hehehe...:thumbsup:

A smaller diameter tire would increase the gearing - the dyno would read an elevated amount of torque.

There's too many variables at play to try & compare your results to any other car on a different kind of dyno.
i know that changing the gearing and wheel size would created higher or lower numbers on the dyno for TQ but would they affect the HP numbers at all?

Personally, I don't see how a dyno can give an accurate reading at all if they all differ. You will never know which are the real statistics, period. The track says it all. Run some track times.
nothing is different from stock except for the CAI and Tanabe SRM.

o wait... forgot to add that the rims are 2lbs lighter than stock.

HP = (TQ*RPM)/5252

Tire diameter will certainly affect numbers if it's not calculated for. If you use a smaller diameter tire, it raises your gearing & you put more torque to the ground. If the dyno doesn't know this & assumes a stock tire size, the numbers will be off.

Dyno software allows you to input the tire diameter you're using (unless it's something like a dynapack which measures directly from the hub). So it's a matter of making sure the technician inputs the correct tire diameter & doesn't just use the stock settings.
i understand this, however my tire/wheel diameter has not changed from stock therefore, we left in stock settings.
