Can anyone tell me how some cars make more TQ than HP on these cars because most of the time it's the other way around?

My car usually is slightly more torque vs hp with the stock cam. Some of the camshafts that peak at higher rpm usually show less peak torque.

Yes. Exactly this. Larger cams with more duration can carry the torque out to a higher RPM. And you must understand the relationship between HP an TQ. TQ is the twisting force of the tires on the pavement. That's what propels your car. I.E. torque is angular force. Now HP is calculated from TQ. HP=(TQ x RPM)/5250 From this you can see that because TQ is multiplied times RPM that the same amount of TQ at a higher RPM results in a lot more HP. Also the nature of this equation is why the HP and TQ curves always cross at 5250 RPM. This is why a diesel engine that makes massive TQ at low rpm doesn't equate to much HP. Say a turbo diesel truck makes 700 ft-lb of torque at a low 2000 RPM. (700 x 2000)/5250=260HP Only 260 HP! Now see in my car how a bigger cam with all other things constant (same boost etc.) makes way more TQ the faster you spin the engine. This results in some increase in peak TQ but a big increase in HP.

Or check this out. A 1.6 liter turbo Formula1 engine can easily spin to 15000rpm. Look how much TQ but very high HP output.
