أها فهمت عليك أخوي ماقصرت والله :) مشكووووووووور :)
بس سالفة الوزن ترى محيرتني شوي .. يعني انت تقول ايضاً من الأسباب وزن السيارة .. لكن اللي اعرفه القوة اللي على الكفرات تحسب ايضاً من وزن السيارة !! بمعني ثاني الحين اللومينا وزنها 3900 باوند وتعطي 277 حصان على الكفر .. لو خفضنا وزنها إلى 3200 مثل الألتيما مثلاً راح تكون فيه زيادة أيضاً بالأحصنة ولا أنا غلطان؟
يعني فوق الوزن الزايد عن الألتيما لكن برضوا ال SS تعطي قوة أكبر !!
وصراحة كلامك مرة عسل الله يخليك يارب ..
وإذا ودك تفصل أكثر فصل والله ماودي أتعبك متى ماكنت رايق خذ راحتك لأني ودي أستفيد من هالناحية كثير :)
ومشكور مرة ثانية :)
There are alot of different dyno's out there. Some can simulate the acutal weight of the car and give you the power and some wont. For example, most Dynojets dont load the car weight. So bascially any car will just have to turn the 3000lbs drum. On the other hand, a mustang Dyno will load the car weight and most likely will show lower numbers if you dyno'd a Lumina on it with a weight load of 3800lbs. If a Lumina dyno'd 280whp on a Dynojet it will show 260whp on a Mustang Dyno because you can load the acutal weight of the car.
The closer the car weight to 3000lbs the closer the dynojet and mustang dyno numbers will be because the dynojet drums are around 3000lbs.
Now if you put a 4wd car on a 4wd Dynojet the load will be worse than a mustang dyno. For example if you run an EVO on a 4wd dynojet it will have to turn arouns 5200lbs and the car weighs 3200lbs. So if u take the same EVO on a mustang dyno and load the exact weightof the car(3200lbs) it will dyno higher than the Dynojet.
Most people use SAE Dynojets and its the standard throughtout the world. So if you want to compare numbers to anyone else the world use a Dynojet and set the settings at SAE for correction based on elevation, temp and density.
So to answer your question.... If Altima dyno'd 240whp on a Dynojet and the Lumina dyno'd 280whp with a weight difference of 400lbs that means they are around the same power/weight ratio.
When u get close power/weight ratio then you start looking at gearing and CD which would help in racing.
Altima's dyno around 210-220whp on a mustang dyno while Lumina's dyno around 250-260whp so its still around the same difference
I hope this explains the dyno operations better for u.
