Dyno numbers
I was wondering how many people have dynoed there 5.7 wk stock and what there numbers were. I had my mine dynoed it put down 211 rwhp and 270 ft of torque. What to see if this similar to what others have gotten.

Re: Dyno numbers
Is your's 4WD? That sounds pretty low. Stock 5.7 LX's (same engine with a slightly better exhaust and different transmission) usually put out ~275-295 rwhp. Most are in the area of 275-280 though.

Re: Dyno numbers
It seemed a little low to me, it is awd. I am going to be redyno here soon and try pulling in a different gear did it in 3rd with tow haul on so going to try a 4th gear and see what i get, i do have a cai, 20% under drive pulley on it now and just got in my Diablo Trinity so going to before and after tune

Re: Dyno numbers
IIRC you should dyno in a direct gear 1:1 4th is OD

Just noticed ,your're in CO.... the altitude is probably whats killing it

Re: Dyno numbers
Altitude definitely doesn't help my situation, should be back on the dyno in the next week hopefully

Re: Dyno numbers
4th is direct with that transmission. If you did a 3rd gear pull, that would explain why the numbers are a bit low.

^ you sure about that?
Got this from here: Jeep Grand Cherokee WK - Transmissions5RFE transmission features

(Standard on Limited and Overland, N/A on Laredo or SRT8)
The 545RFE five-speed transmission has been refined to offer smoother operation and better economy while improving the performance and towing capability of the vehicle. To accomplish all this, several features were added, including a redesigned solenoid to provide quieter operation when shifting from "park" into "drive." A turbine damper also improves NVH, related to torque converter application.
The 545RFE continues to offer dual second-gear ratios to provide a balance of performance and fuel economy. Depending on driving conditions, the transmission will select the more appropriate second gear. A secondary overdrive ratio increases highway fuel economy and reduces engine noise at high speeds.
Transmission ratios:
Gear.... W5A580.... 545RFE
1st .......3.59 .........3.00
2nd...... 2.19 .........1.67 upshift / 1.50kickdown
3rd....... 1.41 .........1.0
4th....... 1.00......... 0.75
5th .......0.83 .........0.67
Reverse.3.16......... 3.0
