There is an abysmal lack of performance information on the trusty little 2.7, so I did some baseline dyno runs for an accurate comparison to any planned future mods. Here's a 4th gear run that the speed limiter cut off at 110mph. The rpms went high enough to be able to get an accurate torque curve from 1,500 rpm to it's peak at 3,200rpm.
We did 3rd gear runs just to be able to beat out the speed limiter enough to record peak horsepower.
The runs were done with a stock 2.7, an Injen intake...
...an LCEngineering header...
...no power steering, no air conditioning...
...stock ECU, no tuning, and Regular 87 octane pump gas.
Here are the URD bone stock baseline dyno runs.
Bone stock 2.7 URD baseline runs:
117 hp 139 ftlbs
119 hp 133 ftlbs
My stock 2.7 baseline results with Injen intake, LCE header, and stock exhaust:
145 hp 158 ftlbs
26 hp 19 ftlbs
I'm happy with the results from just a few simple bolt on mods.
I'll be doing more comparative dyno runs from here on out to log any future component changes, and will post them in this thread.
