Love the AWE mods

RSS did not do so well

If someone knows how to insert the pictures link in here your welcome to do so. I am at a loss as to this.

 

Wow that is over 400 HP with a 15% factor applied for wheel to crank loss.

Nice.

Thanks for the post.

Ed

BTW those are duty free right

 

yeah that is nice, not sure if 15% is the right number for drive train loss it might be less. But nice none the less.

Also this answers the question of RSS plenum working with more free flowing exhaust and air intak and chip... No gain, a little loss... to bad. I was hoping for some inexpensive HP and TQ increas.

 

Very nice result indeed!

Your car seems to be a lot more powerful before the mods than is typical for a 997S - Most dyno at just over 300BHP (wheels). So to get a +27BHP (wheels) result on an engine that is already right at the top of the variation from the factory is amazing.

Seeing these results has finally made up my mind to buy AWE's headers to go along with their cats and mufflers on my car. AWE rocks!

Anyone want to buy a lightly used IPD plenum?

 

I wonder how much difference the software and intake make as opposed to just the AWE headers, cats and mufflers?

 

I guess that pretty much nails it. Thanks, Gerry

 

I will leave that dyno run to someone else.. My baby has done over 60 dyno puls in the last week..

HAHA

 

Edited as I read the plenum graphs back to front. Not good for the plenum at all. You sure they didn't transpose results

Thank you for taking the time to put these up

 

 

60 dyno, damn bro. I sure hope you got a hook up.
Here a dyno would be at least 50$ a pop.

 

He was kind enough to let us use his car for testing so he was properly taken care of. We absorbed the cost since this was for product development.

Doug has been more then patient. We can't wait for him to drive his car.

 

You are right, I recalculated based on 323 HP at wheels = 355 HP at Crank, therefore a 10% gain. Using this you are around 390HP, still not bad.

Thanks for your time on this Doug, I am sure it is killing you not driving your new car.

It would be interesting to see the curve for the 997S with X51 versus these curves.

 

We now have dduncan and florindi with similar results. So, where is RSS getting their dyno sheets - both the website ones and the new BBK ones? They both (coincidentally?) show exactly the promised 27 hp increase.

My BS meter's needle is pegged.

 

Good information, thanks for posting the results... as Rick just said, "wtf is up with the plenum claims"?
Ian, ship it too me, I need a lightweight "T" connector for a sprinkler system
