>Increased power production requires the burning of more fuel, and
that leads to the requirement of more air. More fuel is easy. But getting that increase of air into and thru the engine, is what hotrodding is all about.
>If it's low-rpm power you want; your choices are;
more cubes, or more pressure. You can get more pressure two or three ways; more Scr, more Dcr/ earlier closing intake, or supercharging.
For hi-rpm power;
Pressure is less important, Now mass air flow and cylinder filling is more important.
For midrange; all three come into play
To bandaid a low-rpm power problem, you can use either more stall or more gear, or some combination of the two.
>For a hi-perf streeter, it makes no sense to build a 300hp engine,only to
to choke it with a 150hp exhaust system; or
to sacrifice low-rpm power; or
to gear it so that the power does not come around until 30 or 40 mph; or
to saddle a low-torque engine with a low-stall TC; or
to force it to pull a lotta weight.
>IMO, OP, you are wanting one thing, but the rest of your combo is counter to what you are intending to do. Do not confuse a high horsepower number as being synonymous with your car being fun to drive. If the power doesn't come around until 4400, and your car is stuck at 3000 because of the gearing, well, need I say more?
This is how the formula works;
{(Torque x rpm) /5250 }= horsepower..
Hi horsepower, in a small engine, always requires the shifting of power away from the low-rpm, to get that magic hi-rpm power number you are chasing.
