Gen 5 Camaro Tuning, Diagnostics, Dyno results - HR L99 to LS3 Camshaft Dyno Numbers and Video

Tim (Rockit_z28) has been a great customer of ours and I wanted to share with you guys the results of the L99 to LS3 swap we just did on his car.

Run down of the modifications installed by Heintz Racing

Here is a dyno graph of the results. The lowest run is what L99 cars dyno stock on our dyno. The second run is Tims car with just a CAI, Headers, Catback, and Tune. The Third run is all that is listed above. If you take a look out at around 6500, the camshaft picked up the car around 90 RWHP!

Peak Gains with the addition of the cam were +63 RWHP and +20 RWTQ. The torque carrys way farther into the RPM range, and at times picked up around +60 ft lbs.

Just got back from picking up the car or can I now say my new SS Rocket! The car sounds and runs incredible and more in line with what I was expecting this car to be.

The guys at Heintz Racing our incredible. A big thanks to Jeff, Zach and Bob for all their hard work and professionalism. I highly recommend them to anyone in the area looking to get work completed.

I cannot wait to get this beast to the track and see what it does.

Awesome gains! The car must pull like crazy up top compared to before.

Can't veiw the video what was the numbers for run one and two please :)

Final numbers after some tweaks to the tune and a cooler day were RHWHP = 414 and Torque = 388.

Final quarter mile track numbers for the year were 11.98 @113.59 MPH. The car has more, but needs to lose some weight. :D Car weight = 3,920 fully stock include floor mats and 20" rims on Nitto DRs. This is with less than 4,000 miles on the odometer.

Not to rain on your parade but i was expecting more power and faster times. I put some pacesetter headers, vararam, 165* thermostat and got the camaro tuned and we put down 391 and went 12.2 @113 before the retune.

No rain on my parade. For an L99 car, I picked up close to a 100 HP with my mods. Every dyno is different so I do not go by dyno numbers alone when comparing. Also, the cam is a baby compared to what some people are running these days on LS3s.

Track times are the result of a few things:
1. I am still relearning after being out of the game for almost 10 years. There is some time left in the 60'.
2. I am pushing 4,100 pounds with me in it. No weight modifications and if anything some additional weight has been added.
3. The six speed autos are a PITA. :D

I have compared my track times to some of the other cars. Mod for mod for the most part I am right on par with most 5th gens.

I am happy with it and I know there is more on the table and I just have to find it.

congrats bro as long as your happy with it!:cheers: quick question though whats an L99 to LS3 swap exactly?

Eliminates the AFM/DOD and changes from a single bolt cam to a three bolt cam.

Dyno's are for tuning, the rwhp numbers they print out can be misleading.

If you broke into the high 11's with just a cam install and some bolt on's you should be very happy with what you got.

Agreed. I do not buy into dyno numbers unless they are off the same dyno and not making the same power as simarily equipped cars.
