Re: is boosted hp the same as na hp? (jtrbocrx)

as stated before, a properly built and tuned turbo wont sit and spin at the line...lets say you have a big laggy T4, youre probably not even gonna hit full boost until 4500rpm atleast so by then youre already moving down the line when the power hits

am i completely off the mark in assuming this?

got torque.

Turbo's make more torque now matter how much more HP the NA car has. NA cars get away with it by having a flatter torque band so they don't need crazy short gears or require knuckle splitting shifting skills. NA cars are easier to drive. Turbo cars set-up properly will always be faster up top where it counts. All the really fast cars are forced inducted.

What are you talking about dont need crazy short gears? do you know anything about n/a? of course they need and use short gears. yes they ahve a flat torque curve but you need to rev to make the power and in order to stay in the power band they need short gears... they are not really any easier to drive either!

i would even say na is harder to drive because even with short gears you need to shift very well and very quick to stay in your powerband whereas with boost you can stay in boost, maybe not full boosting but still boosting with moderate shifting skills correct?

It's matter of being "quicker" not faster... With both trans having the same gear ratios, then there top ends will be the same. It's just a matter of who can get there the quickest...

It depends on the driver, some might prefer diving a boosted car vs NA, or the other way around. When I first drove a boosted Civic, I would find myself shiting way too late, since shifts came really quick.

Horsepower is merely a number given by a mathematical equation. It is torque with which we should be concerned about here. Clearly, a boosted car is going to have much more torque than an n/a car. Horsepower is merely the <U>rate</U> at which that torque is put down to the wheels at a given rpm. For example, say somebody punches me 200 times per hour with a force of 130 newtons each time. Now some one else punches me at the same rate of 200 times per hour but now with a force of 200 newtons. Who's going to cause the most damage, or lay the most "power" down?

In a real life application, traction would be the boosted car's enemy. If it was off a roll, or if somehow both cars got perfect traction, then the boosted car would win every time. This is all assuming the gearing is identical.

A nicely chosen turbo [size] would be low in lag, and produce power at optimal rpms for such a race. Its all in the setup.
