5.7 HEMI Dyno Run

[boss_hoss]

Does anyone have a chassis dyno run of the 5.7L HEMI to see how much power makes it to the rear wheels?

I have the data for an engine dyno run which did make the advertised 345 HP and 375 LB-FT, but want to know how much power is lost in the drivetrain.

(I will post the excel file of the engine dyno run if somone can explain how.)

I ask the same question and still have not got a response...... Guess I will have to take to the dyno and find out for myself.

It's tough to get a good dyno because of the 105mph speed limiter. That stops your pulls at about 4300rpms, 1500rpms less than redline. So the pulls in 3rd gear at 4300rpms have been between 240 and 260hp. Can't make judgement on that. People have been making 2nd gear pulls which aren't 1:1 but at least they can get to redline and that's been making 260 to 280hp. You can check out www.dodgetrucks.org and dodgetruckworld at http://dtw.truckmoxie.com to search for dyno's

You can find Dyno results at airram.com. I also purchased the airram cold air injectection system from this guy, and I like it. Oversized K&N air filter, 4 inch insulated tubing. I have been getting about 1.5 more miles to the gallon. But anyway you can look up dyno results there.
