You are just shifting the curve up or down the rev range. Yes, you may be making more power at a given rpm but the peak power doesn't change. If you are making 100hp peak at 6000rpm then all you are doing is shifting that peak to maybe 5000rpm or 7000rpm for example but it is still only giving you 100hp. For our purposes driving offroad we don't want our power up high but rather down low so if we can get what we had at say 4000rpm now coming on at 3000rpm then that's a good thing and the fact that our peak may now be at 5000rpm instead of 6000rpm isn't really a big problem.

Look at the graph and change the rpm numbers on the bottom by say 500rpm or 1000rpm either way and then see what the torque and power figures are now for that new rpm and you will get the idea of what is going on. The graph itself does not change.

Diesel is exempt from OBDII until around 2001
or so.


I was a bit vauge on that

I was reffering to a 2.0 tracker engine.

To restate: Getting the sensors to work into a new host vehical would seem like a fair amount of work

I dont understand.

If you can move the torque curve with the cam gear... and you move it upwards in RPM to say 4800 RPM 100 ft/lbs pk TQ instead of 4200 RPM 100 ft/lbs pk TQ, since HP = (TQ*RPM)/5252, then how can you not be making more HP?

cj is correct  .. by moving the cam gear you don't change the cam lift or duration ..you re just advance and retard the cam lift and duration ,that moved your power band .....still the same cam profile
example if you want power at low rpm you can advance the gear or retard the gear for power on top end..that's on single cam motor..    on  twim cams   can can advance the intake cam and retard the exhaust cam  for valves over lap..that will net some hp   because  exhaust help pull the intake air in ..but we are talking about most of 5hp  depend on what  motor  and set up

this my set up  ..254whp 140ft  N/A
