Shorties don’t add a whole lot. I had headers, CAI, high flow cats, underdrive pulley, Ported TB and made 365 RWHP...

I think I made around 367rwhp, with CAI, ported TB, and long tubes with High flow cats.
Also every dyno is a little different.

312rwhp for stock ? how is correct ? cause 312 + 20% loss = 376 hp on engine... not 400! Are you guys shure that ??? 340 is good ? + 20% is only 408 on engine...... 408 hp on engine is OEM no ? I see people here that says this (((( I was 355 hp/ 365 tq stock on a Dynojet.))))) 355 stock looks great, why my 340 with 50 hp ups ? the math dont match! OEM 400 hP PLUS ups 40 50 hp.... 450 hp engine with 20% loss will be a 360 RWP on whell no ? or is more them 20% omg.... somethink is wrong the engine or the drivetrain with to much loss ? thx Last edited by propeople; 07-21-2018 at 03:02 PM. |

Its been shown countless times on dyno threads that a stock l99 makes 320 330 rwhp. Depends on the car and dyno some may be a little more ...some a little less.

Your right on bar with the rest of us man. My 2012 20,000 miles L99 with kooks long tubes no cats, CAI brand intake, borla cat back, and tune made 366hp and 380TQ. I probley make a extra horse power now with my lighter wheels.

360rwhp/375rwtq
CAI, Kooks LTs and the tune, L99. I did not have a stock baseline. 340 could be the day, the dyno, the (insert any variable here). Focus on the next mods and comparing them to what you have now, and try to have fun!

400 x .78 = 312
20-22% is the accepted range of drivetrain loss on the L99 paired to a 6L80. As others have said, no two dynos are the same, especially when not factoring in weather, humidity, elevation, operation, etc... |

My car made 320rwhp in what I believe to be a stock pull (previous owner left the dyno sheet). 400hp is the advertised factory rating and 80% of 400 is 320hp. With long tube headers & high flow cats, cold air intake, ported throttle body, and a catback exhaust I made 365rwhp and 390rwtq post tune. Shorty headers don't add a whole lot of power. I pulled the ones that came on my car (again previous owner) and installed long tubes because they allow for more power.

the dyno is just a number...does it really matter, it all about how fast you can go down the road. Don't sweat about a 20-30hp difference on a dyno.
