"
*I* have no idea about the JBA headers...BUt... I DO have the JBA midpipes (hi-flow cats)...with the AirHammer and SLP catback. I'm getting 308RWHP.... OH, but it's Diablo tuned too. But with the SC 91 tune I still got 302HP.....

302 versus 308?? I've seen cars vary this much and more during the very same session between pulls! Hardly conclusive unless there's some other piece of info I'm missing (like maybe the car had a tendency to catch fire while on the SC tune, etc. ;) ).

Hmmm... I know Monty pretty well... infact I will be seeing him tomorrow at a local M&G along with 20 other LX's.. I will be asking him a few questions about his tune.. More importantly Mike from Diablo Sport will be at our meet and greet also, maybe I will get some inside info!! :ninja:

Stock RT's put out around 265-275 RWP. Huge losses through the drive train.

Well if any of you are reading Monty's replies in the Diablo Q&A thread he's raving about the Diablo's Tranny controls more than anything. He says the 1-2 shift feels like someone kicking you in the back at WOT with the predator.

keep us posted. or die.

by the way. the rule is that we lost 17.5% of our hp at the crank thru the drive train.

so whatever you dyno at... multiply that by 1.175 to get your crank HP.

and whatever your crnak hp is... multiply that by .825 to get your RWHP

its the method that all vendors use with their products on our cars. and this has been proven to be a steady median for our cars. this does not apply to any platform but the LX

You can multiply engine HP by .825 to estimate rwhp, doesn't work the other way multiplying rwhp by 1.175 to get hp at the crank.

Yeah or you could divide the RWHP by .825 and get the same result as multiplying by 1.212

yea... that too....
rather than saying that you can multiply one or divide the other by the same number... i tried to use the 2 diff numbers. i figured that any one who graduated middle school ought to know that 9/3=3 and 3x3=9 (ie. 350x.825 or 288/.825...) and tried to give alternate routes ;)

Guys, this isn't anything new to performance, more particular to Dodge. Dodge has always suffered huge drineline losses compared to Ford and Chevrolet. This isn't limited to just Chargers/Magnums either. My Dakota RT came with 250HP at the crank, bone stock made 190 RHP--thats 60HP loss. This was about average for Dakotas as well, not just me.
Point being, drive train loss is a tad more prominent in Dodges from what I've seen.

That sounds a little low. I'd say it is closer to 275-285.

well part of the problem comes from the sticktronic ****. a manual car (i heard.....) is only sposed to lose 5% of its hp into the drive train.

Who told you 5%? That's an insanely low number. Try around 12% for manuals, maybe slightly more depending on the powertrain design.
