I guess so. When I look at small writing in top of dyno sheet it says max power 151, and max tq 162, But when I look at the graph the hp reads 162hp and the tq is 151. Am I the only ****in person to see this or what is wrong with my computer.

I was usin rough math sorry I said 148 you said 150. But if hes got 162 at the wheels and 175 at the crank that means hes only got 9.257142% loss at the wheels. But assuming hes got a 20% loss at wheels it would be 203 at the crank. Sorry if it looked confusing

he's got 151.6 at the wheels man! so I have NO idea what you're talking about;)

the TORQUE is 162!

you are reading the graph wrong... the curve that starts out higher, and has a realy steep slope, thats the torque... the one that starts dropping off at 3500!

you read torque off the scale on the right, so follow the curve over to see that it makes just over 160 ft-lbs!

now the other curve, the smoother one, that starts out lower... THAT'S the horsepower curve... you read that off the scale on the left... if you follow the top point of the curve over to the right, you see that indeed the maximum point on the horsepower curve is just over 150 hp!:)

another sure indicator is the large:

MAX POWER: 151.6

MAX TORQUE: 162.3

at the top center;)

You guys are overstating drivetrain losses. I've discussed this before... http://www.nissaninfiniticlub....osses

well, my power estimates are thrown down the toilet considering i cant get the power down. even with an air/fuel ratio of 6:1(a guess. could even be lower..) i burned my clutch like a madman, seeing as its shot. im just hoping to smooth out the air/fuel curve and see if there is anything wrong with it.

sent yu those graphs again 14.5, hope they make it this time (hotmail has failed me many times and combied with a dodgy school network i would have been surprised if it made it).

lOOKS LIKE ALOT OF OVER ENGINEERED HUPLA. Lets talk about my moms S2000. Rated 240 at the crank, puts only 190 to the floor. sorry boss, I dont care what is causing this, but I choose to call it drive train loss. Yes all cars suffer from complex wheel size , allignment, ambient coefficiencyness , transmission fluid, celsius........whatever. Drive train loss. So on the average 240's loose 20% at the wheels so I do my math accordingle.
