Can anyone tell me what the horsepower is suppose to be on the 07 hemi ram at the wheels... I saw something on the edge website that was under 300 hp... I do not have access to a dyno... I am truely impressed with the power in my 4 month old dodge...
Thanks for your help

Using the standard 15-18% drive train loss you would be around 290.

 

Saw a '05 atlocal performance shop get dyno'd before (stock) and after a lot of work, the before HP was 268 at the rear wheels...

 

That is a lot of loss

 

Yea, I'm told Dodge's achillies heel is the torque converter used in the 5.7. A lot more power loss from engine to rear wheels than GM or Ford. Of course, I understand the Nissan and Toyota trucks loss a lot smaller percentage than any of the big three.
Even with the stuff I've done so far (exhaust, CAI, LT Headers, tuner, e-fan, etc.) I won't be above the stated engine HP of 345 at the rear wheels until I do the cam. Down at KRC Performance we calculated on paper I'm around 405 at the engine right now, but I'll need that extra 30 HP the cam I want will give me just to see 345-350 rear wheel.
For the truly power hungry, a torque converter has to be in the mix...

 

an sts turbo will have u at 405 at the rear wheels

 

the MDS hemi dynos seem to be a little lower than the 03-05 hemi dynos. I've seen an 07 dyno sheet that showed the truck at 240 hp, with most being in the 250-260 range [/align]

 

any way to have an easy torque converter upgrade to fix that problem hammer? wonder if its worth considering.

 

Depends on what kind of dyno. Some can vary up to 20% from eachother.

 

From what I have seen, 260 ish RWHP is the norm.
