11.42...damn

 

nutty
look how dirty it was running though, I know thats the nature od diesel but YUCK!

we should all sell our hondas and get turbo diesel Fords

YES, everyone needs a Turbo Diesel Ford truck.

 

I second that, Ford turbo diesals are the shiznit.

 

I was actually informed that it's a swapped Cummins turbo diesel

 

Lordy! I'll bet he was running &gt; 100 psi of boost.

edit: The tractor pull guys are running boost numbers that I didn't believe until reading about some of their setups. AFAIK, billett stainless steel heads are the norm. I read about one setup with triple sequential turbos, each turbo pushing 3 bar. Do the math on that one...

I'm gonna go ahead and guess they don't use Home-Depot couplers do they??

 

fsp31 - pressure doesnt work like you think - 3 bar + 3 bar + 3 bar does not mean it is running 9 bar, it means it is running 3 bar... it could be with 10 turbos.. doesnt really matter...

If the turbos are *sequential* then each one DOES add pressure to the air flow stream, i.e. 3 x 3 bar = 9 bar. If they are in *parallel* then they will flow 3 times as much air at 3 bar. Otherwise you would be saying that having 3 turbos in series would be no better than having 1 turbo, which is obviously not true.

agreed I've heard this as well and it makes sense to me

 

tjbizzo - if you think you are right, tell me what you refer to as sequential?

are you refering to sequential as in the output of 1 turbo pushing air into the inlet of another? In that case you pressure is 3 bar. with only the air from the last turbo feeding the motor... that does not make sense..

if you say sequential as in they are staged sequentially as in one comes on, then another, then another, you are still at 3 bar, with the benefit being faster spool with a properly designed manifold.

any turbo system where the wastegate is set to 3 bar will only hold 3 bar in the motor, give or take a couple psi... I am sure they use 3 turbos, as you stated, to flow more air, not run 9 bar.

also what makes you think that 3 turbos is better than one? size is size. three smaller turbos are probably used for space restraints. 1 huge turbo that flows as much air as the 3 would make the same power, but may hang too far outside the tractor, or something like that

It does not have to be a Cummins swap to be fast. I know of one perticular F350 that pulls consistant mid-12's with the Powerstroke driveline (modified of course). It is very impressive, I could not beleive it until my own two eyes saw it.

Besides Cummins is nice and all but I'd still rather have the PS to work with hands down.

Yeah I wasnt expecting that. That thing was flying.......................................

if each turbo is only making 3 bar but the pressure right before the head is 9 bar then the air would be flowing back toward the turbo. the extra turbos add volume not pressure.

 

I believe the term is "compound" boosting: where the charge air is pushed into the inlet of the 2nd turbo then boosted again. It's more of a diesel efficiency thing. The SportCompactCar mag had an article on it a month or 3 back.

I also saw a dodge at the Woodburn Truck drags that ran 80lbs of boost. He also had about a 9-10" back poking up out of the bed......yowza....

 

there is a guy here in colorado (6000 ft up) that runs low 12's in a dodge 4dr dually.
pretty sick.
anyone seen a dyno for one of those? 800ish tq and 380ish hp.. pretty cool.

 

that car seems like fun

 

Wow that's not half bad at all. The local "Bully Dog" guys that com out only range from about the mid-12 to mid-13 range. Mostly Cummins, couple Power strokes and one Duramax. I'd like to know how much power that guy is making. The guy here that runs 12's is making 6XXwhp and 9XXwtq.

 

Ill have to get pics of a truck we have at work, the rear enigne is a v6 that runs a turbo of each back and then it flows into a supercharger thats bolted to the block. The thing runs 38psi of boost at idle. The truck weights in at a tad of 62,000lbs. The other engine runs the snow blower and has a single turbo on a straight 6. Can plow through up to 6 foot of snow at 35mph, and throws it over a football field in length. With the blower head up the truck can smoke the rear tires without much effort, tires are 5 foot tall. Both engines are detroits. Fun stuff. Ill post pics

Yeah Ive seen that truck before. You see alot of those as much as it snows here.

i agree ill get that truck and pull my 13 sec hatch!...hahahahaha

 

You can always hear a Detroit comin a mile away. Highest compression, highest boost, nastiest sound.

 

&gt;&gt;any turbo system where the wastegate is set to 3 bar will only hold 3 bar in the motor, give or take a couple psi... I am sure they use 3 turbos, as you stated, to flow more air, not run 9 bar.&lt;&lt;

I'm no sequential turbo expert (like any of us on HT are ... ) so I don't know the details, but they were pushing well in excess of 100 psi into the head with this setup. Maybe there was a seperate boost controller working with each wastegate, effectively "adding" 3 bar with each turbo. It wouldn't be that hard to do.
