how many 600hp single turbo'd

how many trucks out there making 600hp to the tires on fuel only with a single turbo, besides Joe D. Do you guys think this is an incredible feat? or a waste?

 

[Diesel Freak]

Do you want to count the HP spike when you back off and then power brake to spool the turbo?

 

[KLockliear]

The P-pumped 24v we just sold and Joe D are the only two I can think of that have dynoed that level with a single turbo only.

Incredible doesn't even start to describe. The key I think is with #2 only. They are the pioneers I have no desire (yet) to get there but it sure is nice knowing it's possible.

what turbo are they using?

So how is dragging the brakes to help spool a big turbo (or any sized turbo) going to create a HP spike? It's a well known fact that the DynoJet dyno does not fully load these engines. On a good hill I can push 41psi with a PDR HX35-16 (no wastegate), yet on the Dynojet the best I've seen is 34 psi (no brake dragging). In my mind HP is HP no matter how it is made.



I've put on my fire suit so fire away

Yeah, most people don't know dynos past dynojet machines. At work, we have a Taylor chassis dyno, I think it is good to 800hp. It works a lot differently then the dynojets, and although it shows less hp then the dynojet's do, you simply can't sneak past it, or have an short term hp engine reach the Hp level that they can on a dynojet. The Taylor is for constant hp, and it is cool to see signature 600's climb on and make close to and sometimes squeak over that at the rear wheels. My lil' spot of info here is that 600hp is 600hp, and the fact that you can make that with 1 hairdryer is real cool, but R. ebel has a point, the dynojets don't load the engine like others, and like many things in life, results may vary Correct me if I am wrong, but I think I saw a HX-40 on the Diesel Dynamics truck.

X hp is not Xhp on the dyno jets. I gained 41 hp by spiking it. I think the massive tq load on the 'Jets mess them up. Of course my tires were smoking too, that could not have helped.



It is no big deal getting 600hp out of these engines with one turbo.

The problem is, the tremendous lag, and the short life of the turbo if you actually use the power.



I can't believe anyone would even consider going much over 450 with one turbo, what a waste.

I thought I was pretty smart, I tried to run big horsepower with a HX35. Proved I was a rookie!



That was over two years ago before I met the West Coast guru of turbo philosophy, Pius of Bell Turbo in Stockton Cal. Pius is known and respected in the mid west as well.



I asked Pius what he would recommend I run as a single to make the kind of power I wanted to run. To flow the air I needed I would have had to go with a HX60! I would never be rude to Pius, but OMG, that would have been a slug on the street



Well Adam, Diesel Wiz, and I went to Pius to discuss a twin system for our Cummins engines. There had to be an alternative to the HX60. Pius developed a beautiful twin system for Adam which worked extremely well. I couldn't wait and was on my third home built system by then. I'm still running that combo now and we make 90 psi with it!



I have found what works for me and I can tell you that I agree with what SP said above. We have seen many people pop turbos in a single config trying to make big power. To date I have not blown a charger

Aren't you running 90 psi without an intercooler? (Rumor) Not that there's anything wrong with that.

 

[HVAC]

Rumors

Christian, where are you picking up these rumors?



I'm betting you know what my next configuration is eh?



We are running 90 psi with the CAC.



Now what's this about running W/O the CAC? Hmmmm?

 

[Sled Puller]

Need a GOOD intercooler? Entreprise has an AWESOME intercooler. hehheeh.

 

[Jim Fulmer]

Nowell, not that I'm any kinda knowledge expert on this but if I had the money and was running a truck just at the track I would plumb the air inside the cab to a liquid to air cooler(huge) then out to the hat and can that air to air, they just work so well with a 5-7 gal tank with ice water in it. I have seen 1800 HP gassers with intake temps a 100 degrees(felpro map) or (FAST... now). If you want pics and dimensions I'll try to get them from him (remember the chassis guy we were talking about from clash of the titans) heck I'll even get you a cost just let me know!

8 gallons ==== Just about 70 lbs. Its not that bad (Just about 0. 050 s). The only problem is that if your using NOs theirs no need for an intercooler. Two, HVAC is probably losing 20 psi across the CAC, if you think you may have head problems at 90 psi (not saying you did) wait till 110.





Competition is a lovely thing.

Drugs are very bad for you.

 

[F8LDOSE]

i wonder what kind of chargers that guys were using that had failures. The hybrid I recently got incorporates a HX-55 front, a switzer center, and a HX-50 rear. They have been in use for over two years now and not one failure to date. Thanks for the opinions, keep them coming. It's funny to see what some people think is a waste or not. To me spending big bucks on a twin set-up and only having enough fuel for 550hp is a waste, almost stoopid????? But who am i to judge, as i'm aware this year will be different.

 

[Sled Puller]

Its called very smart. (is any BOMBing smart?)



Build the engine and charger system for future fuel upgrades, get the rest of the trucks weak links fixed, before you go 700 or more.



I also have more usable power to the ground than any single charger truck on this site, in a towing application.



Anybody with a single charger truck, that thinks they are over 600hp, that wants to race with a trailer, best be quick, before I add more fuel.





What kind of turbos failed? ALL kinds.

 

[F8LDOSE]

yes, I do agree BIG singles are no good for towing, but who's going to tow with a 700hp truck, twins or not. And with that much hp will the weak-links ever be fixed or just created? If you can win with 550 hp and not break at a pull, why would you want that much power. What would be better? to have 550hp and a bulletproof drivetrain to hold up to aggressive tires or 700hp and have to use worn out AT's to keep from breaking?

 

[R.E. Miller]

Not trying to start anything.....

I just think that HVAC and Sled Puller should take the leap, put the cac's they have in nice tow rigs, and just put a short lil' pipe over the engine instead. Then, it will be easy to inject all of the different types of medicine that they might want to try..... for, you know, trucks with their types of ailments
