L99 dyno
How could that be? I dynoed my camaro l99 and it was stock .. 313 rwhp .. And when I installed my intake and my jba mid pipes and edelbrock x pipe .. Tuned it .. 334 rwhp .. Count with me u all .. And my frndz black camaro l99 full bolt ons .. 350 rwhp .. How could that be? There is something to do with temperature or anything? Could someone plz explain to me..

Your car has 400 HP to the crank, not to the wheels.
So you have to correct for the loss of power to the wheels which ranges between 10-20% (as the power is transferred through the tranny to the axels and what not.) More technical terminology, but that is the gist.

Unless they eliminated the primary cats( which are attached with the secondary cats and manifold) I would not expect much. The intake would make a difference, and the mid-pipes depending on their design, but it will not equal the gains from long tubes. What parts does your buddy have?

 The emoticon you used for the thread title is PERFECT for a thread about a stock L99 dyno. But hey man, I'm in the same boat too. I've got a near stock L99. The L99 needs a few more mods to keep up with it's LS3 counterparts, but that's what this hobby is all about, right?

400HP x .8 (driveline/dyno losses) = 320. (320-313)/320 = 2%. I'd say it's a valid stock number, regardless of the dyno. 20HP gains for a CAI and exhaust? About right too... |

yes atmospheric conditions will effect the output... anyone ever notice the car is crisper on a cool day? Also no one dyno reads the same as another...

Out here theres a guy with exactly the same mods as me, same Z06 rims/DRs and same tuner but has an LS3...and only once, just once was his E/T close to mine/same...but traps higher - and thats a given. A well tuned, slightly modded bolt on L99 is just as good if not better as the LS3 in the 1/4

21 hp increase with just a CAI and some exhaust pipes... no reason to complain there...
8 -10 hp for CAI and 10-13 for tune... zero for pipes.  Get some LT headers for real HP increase...
