Yeah, I agree. I like having my good torque down low. And I feel that my car has plenty of ***** down low with this cam and heads setup. But it's the top end that wins races. With downshifting and having rear differential to keep you in the rev range, the revs win out.

Go with under the curve. You have more usable power all the time and across the board. What is the point of peak power if you consider the amount of time the engine will be at it versus at rpms under peak.

Well i see that most of you guys are saying power under the curve is where its at and i agree with that but, which car will ultimately prevail? I know most guys dont race from say a 30mph-80mph. Most guys race till the end of the 1/4 or say to 120+mph and normally wouldnt you guys say that the peak hp car will prevail, everything else being equal?

what you actually want is power after peak. LOTS OF IT. If you make peak power at 5500 and still good power until 6500, shifting at 6800 will put you back at 5500, right at peak. good stuff

Depends on what the car is being used for. With my daily driver I want it all. Low rpm power all the way to the top. I have my rev limiter set at 6600 and I dont want it to stop pulling until it peaks out at the limiter. Most of the time I am getting into street races and I want to kick the guys *** period! no matter if its from a roll or from a stop. All I want my opponent to see is the *** end of my car. So I say both under the curve and peak power. However, I would choose under the curve first.

Power under the curve all the way. Thats why there are some 700 horse Supras raping 1000+ horse supras on the street, because of the usable powerband that they have. The 1000 horse supras are running tremendous sized turbos that take a million rpms to spool em' up, whereas the 700 horse car does it within 1000 rpms of stock configuration.

So launch at 6000 and you're in the top end. Problem solved. Ta-da!
A race from a roll is not a real race, you cant use mph to determine a distance its just weight vs hp
As I stated before niether is perfect, a good mix of both I will take ANY day off the week over a peaky power curve.

Go for peak power, and gear the car accordingly. Nothing will be faster. Besides, even a weak LSx has plenty of low end grunt to get around.

Best quote from a lame movie
"it doesn't matter if you win by an inch, or a mile, a win is a win, period"
it is all about combo, the whole combo of a well balanced ride. One thing some pople can't get in their head, peak HP only occurs for a fraction of time in the rpms, trq is what gets you out the hole. so a well balanced combo will have loads of trq and plenty HP that carries for the highest amount between shifts. That is not only related to motor output.
If that was the case the turbos would beat me all the time, but they don't!, why because by the time they spool, i'm 4>5 car length down the track. Now those guys are running 200+ more horses than me, but their ride is not balanced well for launch, so they loose.

I dunno, ive always been more of a peak kinda guy. If im cruising at 25mph in 3rd im not gonna leave it in 3rd and worry about if i have enough power under the curve, im gonna drop it down a gear and knock the rpms up to 4500ish and take off. so no, i really dont care about under the curve so much.
i guess i just almost always race from a roll so peak is what matters to me.
