Pheh! I have a break between classes so I can play for a bit ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
Dave, It sounds like there is a little bit of truth in both angles we are attacking this. While I agree that hp is what I want on the straights (high speed sections) it's torque that I value in the mid speed sections. For a street car that is relatively heavy with a stock box we need all that torque we can get to put that hp down.
If I had a high revving lightweight car, no question would I want hp.
My brain hurts right now....are we getting closer together?![surrender](https://rennlist.com/forums/graemlins/surrender.gif)

So just scrap torque, forget about it, and when somebody says they've got lots of torque just pretend they said "I've got good low-mid range power" and leave it at that.

Depends how long you want your engine to last ! While there is some satisfaction to go to 7k when oil is up to temp ...you are going to get a lot of thrills at 5-6k and have a hard time finding public roads where it makes much difference beyond that. Likewise these engines don't like to be driven under 3k all the time ( or so they say). Will engine last longer with fewer excursions to redline ? Not sure .. But seems to make sense ...

Mostly common sense:
Don't lug it
Don't rev the **** out of it when it is cold
Vary your RPMs a bit
A driver who is in tune with his vehicle knows where to shift it as it feels right. On my 2 lane road commute my tach is between 2-3K most of the way with the odd blip up to around 4k here and there.

I also subscribe to Dell's torque optimization theory .... 3 yrs later. Good thread!
