A car that makes more mid-range power and torque is going to be faster even if the peak hp is unchanged. That power under the curve, or increased midrange, is going to get you through the powerband faster and your car would be faster. A mod that would, for example, give you a 10hp peak increase but cause you to lose 10hp or torque through a lot of the powerband would be worthless because in the end your car would most likely be slower than what it was to begin with. Understand that peak is not everything.

I don't understand...I askedif it would be fair to say that 28 peak hp from just the plenum would not be possible... probably a lot less. I also never mentioned whp.

And now we must wait it seems. By the way, a true cynic might wish for this to be done by an independent dyno facility, citing a possible conflict of interest. This is not in any way intended as a slight directed at AWE, just a fact of life.

I wonder how many pepole would have paid for the X51 package if it did not increase the max power from 355 to 382 and only improved the curve/midrange power and max power stayed at 355 ???

What X-51 DOES give you is much stronger acceleration right across the rev band. This makes for a significantly faster car and makes the package a sensible purchase. The peak increase is only a tiny part of the story.

I think it is more amazing that anyone would pay so much for so little extra peak power!

Virtually everyone will trade-off top end power to gain in the mid-range. We're at redline .1% of the time. The 7,200 rpm power numbers are only good for people that write ad copy. Besides the fact that torque (which peaks far below redline) is the real type of power that you feel everyday.

Very true Rick and it's something that I truly miss going from my 911 turbos and recently going from my 06 E55 to the 07997S.

You better never spend big money on mods or they'll have to close the forum

This is good reading. Totally agree that peak HP doesn't mean as much as some think- it's USABLE HP that matters, and that's typically in the lower ranges- like getting off the line, mid-range, etc.
I have the RSS Plenum and you couldn't pay me double to take it out- I'm thrilled with it. Felt more from the Plenum, frankly, then my ECU flash- which might mean my ECU flash stinks, the Plenum's really good, or my butt dyno is way off. In any case, I'm smiling, which is what counts most. But also eager to see the results.

Back in the saddle
Kudos to AWE for doing their best (and my cars) to bring this to a honest and fair conclusion. I did not think that this would take so long when I volunteered my wheels but I am confident that they will bring closure to the issue.
All we can do now is wait... and hope that we have a mod that brings us power....

According to some, these mods will make cars faster even though max power reamins exactly the same due to the improved midrange power curve; with that said I'm surprised why the mod companies are not showing or advertising better 0-60 and or Q/M times and traps?
It would be very interesting to see the exact same car with, then without the mods driven by the same driver attempt his/her best runs.
Just a thought
