Texas Speed Engine Dyno L99 Baseline Vs. LS3 Baseline - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Here's a quick dyno sheet showing the baseline of a new L99 test engine next to the baseline from our LS3 test engine.

***This testing compares stock motors with headers, TSP Cold Air Inductions and no accessories***

Enjoy!!

The almost identical torque/hp below 4500 rpm on the L99 shows VVT at work. The big difference up top shows how much the L99 gives up to the LS3 due to the lower compression and milder cam .

You were able to pull 450 hp from a L99 and close to 500 hp from a LS3 with only LTs, intake and a tune?

Dang...I have those plus a TVS2300 and only pulled 515 rwhp!
