C6 Corvette LS3 Header Only Dyno

[@ddbuilds3038]

Nice !! I have same color but grand sport. Planning on intake, CAI, headers and tune. Cant wait to see the difference. Love the blackout as well.

[@andrewferrari6411]

Solid numbers

[@johnhonest9347]

This is spot on my buddy was at 420 wheel with headers and tube

[@juicymangos9820]

I’m getting my car tuned this week. Is this the amount I should expect?

[@iCE-yr3wy]

@@juicymangos9820how much power you making and what have you had done?

[@bikotheanimator6169]

That is insane. I hope I get rich someday to LS3 swap my car. My car is only 348hp, but the engine can't handle. It is stock, but installing headers wouldn't even add 10 hp base on research I have done.

[@ChefofWar33]

Headers and a tune will net at LEAST 25hp on almost any car.

[@Cash2112]

My ‘13 C6 GS M6 puts down 430/428 RWHP/RWTQ with similar mods: Vararam Intake, AR Long Tubes w/ cats and B&B Bullet axle backs. Could be your heat on this day though.

[@c5natie1]

Yeah it was 111*F but it did put down 420rwhp

[@svtcontour]

Oh very nice. So if doing just headers and tune, is there anything to be gained by doing the rest of the exhaust or is that best saved for later on when tossing in a cam..etc?

[@c5natie1]

After the headers I recommend a good x pipe which most header systems usually come with. You gain a few hp without cats but not much when it comes to the mufflers. The stock ones actually don't flow too bad so the most of the performance gains would come from some weight savings as the stock cans are heavy.

@@c5natie1 Awesome and thank you for the info my friend :)

[@daverichard2926]

please what are the arch of your wheels and the size offsett and the size of the pulls and whether it rubs in the fenders or not ??

[@angelo_giachetti]

My LS2 auto only made 485 with 6psi boost!

[@John-qz4cv]

Why do you keep it at 5 grand? Rev that thing out!

[@c5natie1]

Power pulls were to 6500rpm.

[@1SIK335]

What adjustments did u make? Why was it pulling timing?

[@c5natie1]

Didnt make many adjustments other than just a bit with fueling and timing but the ambient temps that day were 111*F. Thats very hot and not ideal for power pulls. Most cars will pull some timing on a day that hot.

[@omegasquad868]

are those CCW wheels? what size and what tires?

[@c5natie1]

18x10.5 and 18x11.5 with Nankang AR-1 tires. 295/315

[@camdenhanson7062]

[@Bigboss-bg5fp]

[@JesusGuzman-nu2nw]
