Torque Boost!
 
I just had a funny thought. What if someone marketed a fuel additive called "Torque Boost" or something like that?

"Guarenteed to increase your engine's torque by 10%!"

Just wait, it will happen now that I've said something about it.

thats because most diesels are either matching or beating the HP numbers with Tq

HP = (RPM * TQ) / 5252

The TQ vs HP argument is completely proven when you look at the CRX HF.

If you look at its powerband, it has the powerband of a diesel for the most part.

Loads of TQ (relative) at a pretty low RPM.

Is this something that can be done with ECU tuning?

I believe it's more a function of the individual characteristics of the HF engine.

I'm sure ECU tuning plays a large part, though.

I think the camshaft is what basically determines the torque characteristics of an engine.

you're right. A long time ago bagpipe goatee told me to swap out the camshaft from a civic STD if I wanted better gas mileage. This could be why.

(the STD was the fuel efficient hatch civic of the time)

I'm still reluctant to do any major modification to my engine, as it's build for economy as it is. This isn't to say, however, that other people cannot benefit from a camshaft swap.

lots more than just a cam affects power, lol
