Is that 181 hp; or 181 Kw?? seems odd to have hp for one; and Nm fo rthe other... :dontknow:
 
Nice dyno run none the less...

181 HP it\'s a \"KM\" means \"HP\" in english. And why ot is strange to give torque in \"Nm\" we have a metric system :)
It has a small FMIC, 370cc injectors, MAF from SR20DE (nissan sunny GTI)  T28BB 0,9 bar , MBC and a crapy exhaust pipe.

181 hp is very respectible whp number. Why are you using such a large turbo? Do you have plans for a lot more power?

km, ps, etc. = Metric Horsepower

1 km = 75 kilogram-meters of work per second
1 hp = 550 foot-pounds of work per second

1 kg = 2.20462442 lbs
1200 m = 3937 ft

75*2.20462442*3937/1200 = 542.4753963 ft-lbs/s

181*542.4753963/550 = 178.5237213 hp

Whats whp?

Is that power at the wheels or the flywheel?

WHP is power at the wheels (wheel horse power)

What boost do you have to run to get 210whp then?

237bhp @ 6,105 rpm

Almost any dyno test not from a manufacturer is going to be at the wheels ...  For one, the power at the flywheel doesn\'t matter ...  Two, you\'d actually have to lift your entire engine out of your vehicle ...

It\'s at the wheels ...  The power at the flywheel would be approximately 15% more than the wheel power ...

BTW, it\'s not 181 hp !  Read my post above ...

I used this turbo to avoid any problems with lack of flow and to have cooler air after compresion. And the spool of the BB is awsome. When i instaled it i wanted to test if it make more boost then originaly 0.4 bar. I disconected the hose from turbo to westgate and made a test. On second gear i got about 1.2 bar and 3K rmps and the intercooler pipe poped of :). For now it\'s inaf with the HP\'s. I\'m working on suspension now. Today i replaced bushings on the rods that goes from fron control arms to chasy. Tomorow i will take out the steereng rac and take it to the repair shop for regenracion. It\'s in very very very bad condition. The car is unable to drive straight now it serchs for the road all the time.

181hp is very close to the revised 178 so not worth mentioning really.

When I\'ve seen dyno\'s they recalculate the wheel figure to that of the flywheel by allowing the transmission to freewheel after the run. They use this to calculate the loss. If the car was lightweight and had high tyre pressures it would increase the wheel figure but would ultimately come back to the corrected flywheel figure.

Chester - What turbo are you running? I don\'t know your specs?

T28BB .60 AR compresor hausing and a T25 .64 AR exhaust hausing.
The diference in power at the fly and at the weels is unimportant. Because it\'s only HP\'s not Nm\'s For example subaru impreza has 60% los of powet on the drivetrain. So 260 at the flyweel and 120 at the weels. But The torque is the same there are no los in that. To be exact the torque at the weels in multiplicated by transmition and diferentials. So 200 Nm at fly is about 800 Nm ant the weels on the fourth gear.

Where the hell did you come up with these numbers ?

1)  Subarus lose 20-25% of the power through the drivetrain ...
2)  A loss in power is caused by a loss of torque ... (Horsepower = Torque*RPM*2*Pi/33000)
3)  You don\'t seem to have a firm understanding of the properties of power and torque ...  Power is what\'s important ...
