When I said 2 models I was referring to the two above the 20G. The 20G-H and the 20G-N. Either way they are just bigger exducer wheels.

Siueclipe, your car as it sits has the potential to put down high 300 and maybe even clear 400hp. It's going to be a matter of tuning and race gas.

Armond never crossed 400hp until he added race gas. Using pump gas to max out hp is a bad idea.

Whatever someone dyno's at, you can expect at least 10whp more on the road.

With a dyno jet roller dyno your looking at no real world resistance on the car or even drag from moving through the air. If anything you lose that hp when you go on the road.

If the dyno was setup correctly the only factor that should matter as far as effecting hp would be that you would see more airflow and cooler temps.

cooler ambient air temps dont mean shit on a car thats intercooled. it does however increase the efficiency of the intercooler to have cooler air flowing over it. its the actual intake air temp in the manifold that matters.

A pull down the track in June or July may not yeild better results than a dyno pull in December.

the actual acceleration of the motor is much slower than when it was tested and it ends up being leaner.

you want to tune full throttle on the street, then dyno tune.
or better yet, load bearing dyno

a dynojet calulates horspower and torque based off a few things.

one horsepower is equal to a 550 pound force through a distance of 1 foot in one second. so basically it would take 1 HP to lift a 550 pound weight up 1 foot in 1 second. to meausre hp you need to know the force in lbs as well as the velocity in feet per second. it emasures acceleration with the juge drums as well as how much forceis turning them. the force on the dyno drum is calculated from acceleration using newton's 2nd law, force = mass X acceleration. if they know how much the drums weigh and acceleration is measured, the computer can calculate horsepower. torque is calculated as well with horsepower X 5252 / RPM

once they have the numbers a few correction factors are applied, some made public, some hidden. public correction factor is the SAE correction. (standard) this formula assumes a mechanical efficiency of 85%.

the formula used for a dynojet inertial dyno is: CF= 1.18 X (29.22/Bdo) X ((Square Root(To+460)/537)) with 'To' being intake air temp F, 'Bdo' being barometric absolute press. this correction factor is meant to predict output in varying atmospheric conditions and is a +/- 7%
