how much horse power does one loose between the flywheel and the rear wheels. Are most hp ratings at the wheels or the flywheel?

BCisme

all manufacturers rate power at the flywheel. drivetrain losses are usually 15-20%, varying for auto and manual transmissions. automatic trannys lose more power in the drivetrain, mainly because the transfer of power from engine to tranny is made hydraulicaly, via a torque converter filled with fluid,not mechanically. the crank spins the fluid filledtorque converter, wich uses thefluid to transfer power to the transmission input shaft.

YOUR BEST BET IS TO FIND A DYNO SERVICE CLOSE TO HOME OR IFR YOU GO TO THE TRACK THEY SOME TIMES HAVE ON THERE. PAY THE FEE USUALLY AROUND 75$ AND AND FIND OUT WHAT YOUR CAR MAKES INSTEAD OF BEING ONE OF THESE PEOPLE THAT GOES AROUND ADDING UP HORSE POWER FROM BOLT ONS.<IMG src=smileys/smiley4.gif border="0"> MY FRIEND HAD HIS DONE AND IT WAS JUST BELOW 300HP HES WAS WOWED, DIDNT EXPECT IT OUT OF HIS NEW MOTOR.

One more thing, what is the easiest way to get back some of the lost horsepower from the flywheel to the wheels? Chip, exhaust, etc?</P>

well your not going to actually get it back, because no matter what you do to your engine.. the power has to go through the driveline. but, you can always beef up your driveline to make it more efficient. a nice higher, say 2600 or sostalltorque converter, a shift kit, and some 3:73 or 4:10 gears will wake your stang up, and prob drop at least half a second of your 1/4 mile time, more if you have good tires, and have/plan to have some added power.

Easiest way to get it back, change to all synthetic fluids. Synthetic engine oil, tranny & rear differential oil.

A buddy of mine with an Iroc-z did this and netted a 10% hp increase pushing him over the 300hp mark, just from oil

also you want the light rims and tires you can find as this is unsprung wieght
