10.5 Hotside's..... ANy power difference?
The WRC car does a very good job of this, and makes something like 400ft/lb at 3500rpm
It is a little more then that. These things are limited to sub 300HP with block off plates and such BUT there is nothing that says it can’t have torque. There is even a 15G turbo that spools even faster then the TME turbo. These rally cars also have Antilog which will get them 30PSI instantly off the line too, I have seen on of these cars have like 270HP and over 500 Foot pounds from having an instant spool and of course race gas and massive amounts of timing.

who is TME?
Sorry for the slight hijack.
Isn't the 10.5 hotside what all '05s and '06s are running right now?
My belief is with say an Xede or other such electronic boost control, the spoolup can be optimized to take advantage of the 10.5 HS.
As far as the torque vs. horsepower ideas ... Torque is rotational 'force'. Force is what you feel, and its what keeps you going at any speed. In fact the tires on your car are the final step in converting rotational force (called Torque) into linear force, called 'force.' (All right no Star Wars crackpot jokes here.) In order for you to maintain any speed you have to overcome the forces acting against you at that speed. These are such as drivetrain losses, wind friction, tire against road friction, and a handful of others. If you're producing more force than the force acting against you then you accelerate. If those forces against you are greater than what you're outputting, you decellerate.
Power (aka Horsepower) is how much force is expended over time. The equation to get from Torque to HP is basically this: HP = Torque * rpm * constants. The constants just get us to the right units we like to use. So in our case, its from ft-lbs., and revolutions per minute, to Horsepower. It is always good to see a graph of what you are working with in the motor tuning world. We can say from there that HP is really just the same type / catagory measurement as Torque, but we multiply it by rpm to find our numbers. RPM has a big play in automobiles, because of gear shifting etc ... we want to keep our torque just as flat as possible so we can get to a nice area to 'shift.' Total peak torque, and how long you can keep it there, are ultimately more important than peak HP for the EVO's application(s).
