hmmm heard it in person yesterday, sounds so mean

Why is it that the tq curve matters more than the hp curve? Everyone keeps saying a flat tq line is optimal...why?

The torque curve shows you what you will actually feel when you accelerate. A flat torque curve means you get a constant amount of thrust as you sweep through the rpm range. This is more desirable because it makes the acceleration predictable at any rpm point and doesn't unsettle the car as much as a peaky curve would. It also makes it feel like the motor wants to rev beyond redline instead of feeling exhausted before redline.

So why is it that torquey cars are more desirable? Is it that the actual tq of the engine is what dictates the amount of acceleration? someone told me a while back that tq determines how fast you get to your top speed, and hp determines the top speed.

Idk if that's right or wrong, or whatever lol

I have an odd question. Do you guys have plans to do anything with a smaller turbo with a wider powerband and faster transient response?

HP is just a calculation based on Torque. Torque is the actual force being measured at the wheel or flywheel.

If you have 150 TQ at 3000 rpm and 150 TQ at 7000 rpms, both are the same amount of force. If you stomp on the pedal at either of those two RPMS you will feel the same thrust propelling you forward (in the same gear of course).

The only thing HP tells you is where that torque is maintained too. To explain it in the simplest of terms....A bigger HP number (relative to the TQ number) means the torque is maintained to a high rpm. A bigger TQ number (relative to the HP number) means the torque is not maintained (drops off early). But really you should look at a Dyno graph rather than just looking at numbers. This is why the torque curve is important.

This is why an s2000 that revs to 9000 rpms has such a giant HP number. It maintains 150-160 ft lbs of torque all the way to 9000 rpms.

HP=(RPM * T) / 5252

So what is T? A constant or just time?

One last question so I don't throw this thread off topic...what determines if a engine can be torquey or not?

T in this case is Torque.

Ah, I should have seen that one coming....lol

Our 4-1 header, oil cooler, washer reservoir, and WMI system are all going into production right now. Our production return style, swirl pot, flex fuel system will follow shortly after these components have been completed.
