1000 hp 3400ftlbs.........What?
Did anyone see that 94 suburban with that twin turbo 12V.......Can run 150psi........Yikes!!!!
Its in the latest Four Wheeler mag........In the TTC section....
Are #'s like that possible?

I saw that today in the mag. 
I think there could be some fibbing invollved in there somewhere. Besides is there even a dyno that can measure those kind of #'s. Nice looking Burb though, I like the old Yota better.
Too bad it had a 6.5 Detroit in it though. 
Diesels are really starting to make a hit in the hard core wheeling world now. I know of two guys that have full on tube frame crawlers with 4BT's in them.

There's a heated discussion going on over @ www.pavementsucks.com in their diesel forum.
I put my $.02 in and it was more like $37.56 worth!
The truck is a 24V with a P7100 pump conversion. The short NON-detailed article about it makes no mention of any engine mod's except for the pump and twin's. The add does mention EEP so I imagine there's quite a bit of work done by them on the motor.
IMHO the truck is probably around 700HP and 1500FT/LBS (maybe more I'm not sure about TQ #'s on twins), but he's no where near the BS level's he fed the mags.
However I would absolutely LOVE to see that thing in person!

Even if there was a dyno how would you keep the tires stuck to the rollers with 3400 ft/lbs?
And what tranny will even come close to putting up with a 3400 ft/lb load against it
? That is really pushing it for a 18 spd big truck tranny - I am told the biggest capacity ones peak out around 2200 ft/lbs of input torque

My guess is that those are "on paper" or "in theory" numbers of what it COULD do on a dyno.
As we all know, theoretical numbers rarely pan out in real life tests.

My main beef with the claim is that the numbers don't match! What RPM are these claimed numbers being achieved?
Or, put another way, at what RPM does 1000hp=3400 lb-ft?
1544 RPM! I'm not aware of a SINGLE CTD that makes it's peak HP at that low of an RPM.
If the peak HP occurs at a more typicaly rpm for a bombed 12V, say 3500 rpm, then the tq at that rpm is only 1500lb-ft! That means that the tq curve of this engine has dropped 1900 lb-ft in only 2K rpm-- over HALF it's total torque output.
Maybe that's a little peaky?
Considering that a typical 18L Class 8 truck engine makes about 2500lb-ft, I'm not about to believe that an engine ONE THIRD that size is capable of 30%+ more torque. Note, I say TQ, not HP. HP can "created" by astronomical RPMs-- a common way to get smaller engines to make more "power". TQ cannot be gamed like this-- you either have it or you don't.
So not only is this guy FOS, but he must think we're all about the dumbest schmucks to fall off the turnip truck.

gotta remember the editors of 4wheeler magazine are also the guys that name trucks like the lexus gx450zl2bla bla bla as 4wheeler of the year!

That truck is from here in town, Kelowna BC. His name is Jason and he owns Only Diesel Performance. Seems like a straight up guy to me. Numbers do seem a little unreal but I have seen the Boost guage, actually it's an oil pressure guage hooked up to boost. The shop does have a Dyno so who knows. He used to be an engineer for BD-Power in Abbotsford. Had him do some work on my truck, seemed to know his stuff, would definatley deal with him again. I think the only thing stock on that motor is the block. And yes he does have a hard time keeping trannies in the thing. I think now it's running a 6sp but not too sure. Anyways it does a wicked 4 wheel smoke show on 44" Boggers
