Default cammed LS3 dyno: Colder weather + more miles = +16rwhp/ 25torq!!!

No changes to my setup at all besides more miles now and 63 degrees out when dynoing instead of the Texas summer heat!

Before same day back in August LG dyno: 479rwhp 21st Century dyno: 487rwhp

Today @LG: 495rwhp / 452torq




The pics are with my iPhone I'll post better pics when they email them. So from milled heads I should pick up around 15rwhp putting me right around 510.

You said it, weather. Blowing hot *** air when you're on the Dyno don't help but 63* cold air sure does.

The afr is a bit rich between 4000-5000rpms. Just run at the track to back the numbers up.Nice numbers though.

Any good tuner will always add more fuel at Peak Torque. Thats where the engine is most prone to detonation and also is using the most fuel.

Forced induction fueling demands are quite different.

I like to run a steady afr throughout the rpms. I just run a little less timing at peak tq because of the highest cylinder pressures but i suppose throwing more fuel at it will also work for some.

I will run about 2 less deg of timing as well at peak tq Thats why its called a timing curve.
