we were discussing this last night as well.

Depends on what it is really and the setup. If its a 1200whp supra, there is no such thing as powerband. A 3.0l or 3.5L can only spool so much, rev so far.

Same with the EVOs , same with Hondas, etc.

There was a guy on HT with a SOHC D series that was making like 430whp on a built motor with a 30R. His power band was useless. He was revving to 8500 and i think he hit full boost at 7000rpms. He didnt make over 200whp until 6800rpms. so his car only made peak power for maybe 1 second.

What was worse was his gearing. If he shifted he fell out of boost by like 2000rpms.

But everyone on HT (all the noobs) were like "OMG THATS CRAZY IM DOING THAT TO MY D SERIES!!!!".

Little did they know that the same car making 250whp with a T25 would smoke that car from stoplight to stoplight.

Same goes for guys that buy those Ebay turbo kits with the t3/t4s on them. Unless you have an h22 or F motor, those turbos are too big for stock motors. Power is too peaky, too laggy , etc.

Most people want a street car, and a street car is better served by a proper spooling turbocharger. Not max HP.

If you are into highway pulls, then it doesnt matter as much. Because the "area under the curve" doesnt mean as much to guys who are going to be high in the revs anyway.

Go look at the 700whp EVO we just tuned, his powerband is really laggy. But he doesnt care, he does highway pulls from 6500-10,000 rpms. An thats where he makes the most power.

Now if he was on a road course, a stock evo would wax him.

What you are mentioning is simply AREA UNDER THE CURVE, the question is, how big is that curve and what is the car being used for.
