780hp/1800tq??

[BlakeDavis]

I know a little about these 3rd gen trucks, but I am a 2nd gen guy myself, so when a guy with a common rail told me he was making 780/1800, I had a hard time believing it. I ask what all he had and he said you name it, I got it. Propane, nitrous, a couple different boxes, a turbo etc. The truck would spin the duals in every gear and he was disappointed because his "unslippable" Centerforce clutch wouldnt hold. I don't doubt 500-600 horses, but just how reasonable is 780 with the common rails? Asked him about boost and he said 55 lbs. , no rings.

He'd have to be pushing serious druggage, and even then the HG would have lifted pushing that kind of chemistry.



There are quite a few big dogs that aren't TDR members.



But there are even more talkers.

The strangest thing about his line of bs is when he said a turbo. I would think he would have twins IF he had that much power.

Also I was not aware of a single cernterforce that was made to hold 700+ hp. Heck thats what the "iron gaint" DD clutch is for...

running 55 psi with twins and no rings is believable, but on a single, then propane cause the rail is dry, then nitrous to burn the un burnt, riiiigggghhhhttt, maybe he said 1780 inch pounds... .

 

[Patriot_RAM]

The PSI is believable -- With an SPS66, I see 65psi when it comes on with my fueling up and it'll level off right at 60. But... . I'm not pushing anywhere near that power with my single. Maybe 500 or so... That's a ton of hp and tq for a third gen. The engine is capable, but it takes an almost perfect combination to get there. I haven't seen many in that range. Ask him what turbo he has.

 

[BTighe]

bring him to the next dyno. bet ya he aint smilin after his run

 

[RChamberlain]

he probley is adding what the boxes of every thing say they add to the motor hp like the motor is 325+100hp propaing+ 100hp Nitrous so on and so on.

 

[RJPotts]

That would make sense. I know a lot of people that do that, and it makes me laugh when they do finally put it on the rollers. Its usually D-trash and P-joke owners though. Unless they aren't TDR members, he'd be corrected by now if he was.

Seeing is believing.

Pull it!!

 

[mhlbr]

I am wondering how dry his fuel rail is getting. I know it does not take much to stave these things

 

[KLockliear]

1800ft-lbs - I call BS. Not with that HP anyway.

 

[BlakeDavis]

I am glad you all agree with me. He may have said twins, hard to hear over a couple of rattln dodges, but i am positive he said 780 and 1800, next time i see the guy i am gonna try to talk to him a little more and see what i can find out.

 

[Hohn]

I highly doubt that even 1600lb-ft has been reached by more than a select few in a pickup.

Even the pullers that have 1200+hp or so may not have that much torque, because they are winding up their engines so high that they are getting closer to 5252 rpm where hp= tq, or they are 1:1 ratio.

So, for him to have 780hp AND 1800 lb-ft, he would have to be making that kind of power at 2275 rpm!!

The cylinder pressures to make 780hp at only 2200 rpm are incredible, and I *HIGHLY* doubt that these numbers have any veracity to them at all... .

local guy here in town told me the same thing ...



"555 horse ... your truck don't stand a chance"



i chuckled and asked where he dyno'd at



"didn't dyno, it's 325 from the factory and i've got a 230 horse bullydog on it"

:-laf :-laf :-laf



Thats a classic line!!

 

[CTDFreak]

That's funny...

 

[Hohn]

So, I guess that means I have 395 Hp with no box or boost fooler, because I have 150hp sticks, right?

Heck, I musta had 450hp when the VA was on

If you put it on an engine dyno you would!

 

[JasonCzerak]

With just "one" box (with intake and exhuast mods), AT THE FLY WHEEL, adding stock numbes with what ever box's number is rather close. here's how I figured.



325 + Hot juice 180 = 505hp



well, figure 20% lose in drive train. STOCK clutch with 45,000-ish mile at the time of dyno HAS to be around 5-7% slippage? the edge will peak at 9% at times. .



I dynoed at 422hp as noted in my sig. I have open exhaust, and swiss cheese air box minus some parts in the tubes.



So lets go with a moddest 7% slipp rate on the clutch for an overall power off of 27% between flywheel and wheels, that would come to about 523HP at the flywheel (976 foot pounds).



Even at 20% overall power loss (clutch and power train), that would be about 505hp (922 foot pounds), this would be in line with 180hp "MORE"



Now, when you add a pressure box, injectors, turbo, you naturally can't add the numbers, some parts couter act other's positives, or enhances their negatives and blah blah blah.



This is strickly for one power "box" , atleast with Edge Products. ;-)
