Please educate me. They are advertising all these new ricers with V6's with over 230 horsepower. My 4.7 boasts 230 HP. How can that be? Do the ricer motors only have this type of power in a small powerband? That would make sense. Please explain how this works. I find it hard to believe that these small engines have the same power as mine. Thanks

well you gotta think they may have it but its gonna be close to 6k rpm's and their torque rating is going to be MUCH MUCH lower than yours, i am guessing yours is 290, (mine is) and thiers would probably be under 200

First of all they are imports. Not ricers.
That said, horsepower is torque x rpm's/5252
When you hop onto a dyno, it doesn't actually measure your HP, it measures the torque, and uses calculations to find the HP.
Look at the rpm level's of these import's power.
THe integra type R (the real ones) have 195 HP, but they also have a tach that goes up to 10,000, and redline is at I think 8000 or 8500.
This is the same way street bikes can haul ass, they have virtually no displacement, but they reach ungodly rpm levels really quick.
Another example is a guy I was just talkin to on AIM, he has a saturn, it boasts 110lb of torque, at 4800RPMs, and 130HP, at 5300RPM.
Yeah 130 might sound like a pretty good amount for that lil car, but 4800 rpm's is pretty high, until he gets up that high, the car is gonna be a slug more than likely.
HP usually hangs out in the upper RPM bands, and imports have been built to be high revvers (type R's, S2K's, and so on) so they can get high HP numbers out of a tiny engine. Granted, they couldn't tow a trailer cuz of a horrible lack of torque (type R has 160lbs) but when it comes time to hit the 1/4 mile, once they hit the high RPM's its a whole new world.
