When you run your car on the dyno there is no air flow going through the radiator to take away the heat generated. The dyno fan is meant to compensate for that so the temps can stay reasonable.
The car is not idling and in most cases is rev'ed to redline in several gears, several times. No sorry but that statment about the dyno fan being for show has to rank right up there as one of the most stupid ever.
That's 100% correct. The dyno fan is absolutely necessary to cool the car to avoid overheating it. Normally air flows at high speed to the radiator when it's in movement, but when the car is static there's no airflow at all so the fan has to do all the work. It's not just for decoration.Quote:

Chasers, they are great tuner though,I'm not to sure what's the reason of not using the fan, but they have done some research of the car and before they even started to install the e-manage.
The dyno results might be quite low for my liking though, it might be caused by dyno itself, probably the fan and probably caused by the weather since it was closed to 30 degree C. However before and after tuned showed significant gains for my car 12 kw and tom's car to be around 10 kw.
E-manage is not better than stand alone unit however in value comparison, it is really worth it though even to be compared with hondata reflash since e-manage can be re-sold and it works well, no CEL to be appeared.
Anyway, I haven't got any review for the my car since I'm in overseas unfortunately, I left a day before the car finished the tuning. Lucky, Tom
you know the amount of heat generated when your car is rev to the max?Quote:

On another note :), let's all end the dyno fan talk and stick to the E-Manage talk.
yes more juicy detials about the e-manage =D
its to my understanding that based on the 2nd law of thermodynamics, having your engine temp run high will linearly reduce its overal efficiency. theres other factors that come into play too, like havin an enginer thats not hot enuf will also affect the combustion process or sumfin.Quote:

What does entropy and equilibrium have to do with how efficient a hot engine runs? The 2nd law states that heat moves from high to low regions in order to increase entropy. If you have a cold block, heat from combustion is transferred into the block and therefore there is less energy to produce the expansion of the combustion gases, thus reducing efficiency when cold. Conversely, a hot engine means that heat flows at a lower rate into the block, thus giving better volumetric expansion. The reason why we don't want hot engines is because it warps and cracks.Quote:

just wanted to clear up a couple of things. first the dyno fan. i cant understand why you are under the impression that we dont use a fan? the fan is used whenever a car is dynoed to keep the cooling system under control... its that simple. since it is a FWD car, the fan is at the back of the dyno room (front of the car), you cannot see the fan from the front of the dyno room.
secondly... the dyno is an indication of power. faily accurate, but dyno's do vary. at the end of the day, nomatter where you get your car dyno'd the engines output will be the same regardless of the power figure. dyno figures vary from dyno to dyno, due to inconsistencys between the dyno operators and enviroment variables.
Hi Chris,how ur u?is it the fan on the wall you have on the left hand side?cause the fan is not directly in front of the car so i tought that the exhaust fan.and i didnt see the green big blower fan like on the other dyno usually use.if you really use the big blower fan, then i am sorry about my bad impression.maybe i didnt see where you put the big fan.my bad!sorry for this misunderstanding.
Btw,thx for the great tuned:thumbsup:!like it so much!
