So I had to do it. I brought my truck to Accurate Automotive in Logan and stuck her on the dyno. We ran through almost all the the tunes on the Hydra. Max HP was 271, max TQ was 611. Not on the same tune.

I have read all of the controversy about dyno's, so, yes, it was a mustang dyno. If I believe the internet, which I hear it is illegal to lie on, my actual numbers are somewhere around 117 HP and 211 TQ! Thats a joke. Don't troll me.

Is this about the max I can expect on stock sticks?

On another note.... It almost killed me when they were doing the "pulls". I have never driven my truck that hard! I was waiting for something on her to explode!

 

Nah, you should max somewhere around 300-310 hp and IIRC somewhere around 650 TQ. That's with all other systems operating correctly. I have a dyno graph of my F-250 with stock sticks, Tony's tunes and Van turbo - I'll dig it up.

I remember the first few times when my truck was on the dyno - I remember the engine screaming and wondering if I was gonna make it home with the camper......

 

Wow, I actually found it - then another WOW when I saw the date, this was from almost 10 years ago, making me feel old.

This was with stock injectors, T Wildman tunes, Van turbo, Ford AIS, 4" exhaust, DI intercooler, stock fuel, stock HPOP, Jon Faubion Tranny.

309 HP, 649 TQ

A stock truck is around 225 hp

 

Do you have the Graph? Or did they print one for you?

Sounds to me like he didn't set it up before the runs.

 

I do. I just dont have a scanner at home so I cant upload them.

 

This is my stock injector truck with H2e turbo, WWII, Adrenalin HPOP, FRX, and BTS. 356 Hp but only 610 ftlb tq. I think PHP pulls some tq out of there tunes?

 

I can't actually see the RPM Graph so I'm guessing. But, that's okay. Because the Graph does look encouraging.

There is nothing to complain about this run.

Diesels are Torque Masters - They Top Out Quickly while RPM Horsepower is Steady.

The HP steadily increases following the Torque Peak.

There is a visible increase over stock. How noticeable? I'm guessing you wanted more. Or, you "expected" more I should say.

Well, it doesn't work that way. There are many different considerations. Injectors, Fuel, and Air are just a microcosm of the entire performance spectrum. Had this have been a loaded calculation, your torque would have taken off before 1,500 and the Hp would have been higher in the end of the run.

 

Bleeds Blue, also is this an E99 truck with the smaller injectors? I feel your pain. I've seen the way they load the trucks on the dyno's, makes you wonder if it's going to blow up. Usually no problem, but who knows. It's still much better then stock.

 

I dyno'ed 311/681 on stock injectors. My truck always seemed to make a lot of torque though. After further mods (including 238cc sticks), I made over 1000 ft-lbs & 450 hp on the dyno.

 

Bill at PHP said it was a good running truck based on all that he saw. He said he doesn't see many trucks make those numbers on stock injectors.
We didn't discuss specific results, the purpose of the runs was to provide feedback on how the WW2 would work on the h2e turbocharger.

I was pleased with the horsepower number but a little disappointed with the torque number, I expected 50+ more ft lbs. I wonder if do to the PMRs does Bill pulls some torque out of his tunes?

When you say loaded calculations, what does that mean? The dyno was pre-loaded with my vehicle weight about 10k.

 

350 hp on stock sticks! That sure is great IMO, that's what got me wanting the H2E so bad.

 

Thanks! Actually the WW2 bumped my numbers about 30 H.P. in that tune. About 17 H.P. bump in my stock tune.

 

CGMKCM,

I wonder if Tom might have thought your graph was the OP's?

Anyhow, I'm trying to recall the compressor map for the stock H2E. Wasn't the stock H2E setup geared more for higher rpm's? What a difference the wheel made.

Edit: How did the SOTP feel after the wheel upgrade?

Sorry to get off topic.......

 

I busted the 400HP mark when I went from the swamps 175's to the 238,s.

 

Like I stated above. There is no shame in that run. It looks good.

What you have is a good overall "no load run". Which means the TQ/HP move in the same realm during acceleration. A more accurate snapshot of what's happening at the wheel and not the engine at the time of day you did it, the intake air temperature, the engine temperature, and the elevation you were at.

"Disappointment" shouldn't enter your mind. You set out to see what it would do on a WOT run. Now you have the information you set out to get.

You now have a fact to deal with. Do you want (or need) more Torque? That's the only thought you should have.

A "Loaded Run" takes into account many programming factors. Where, when, weather, heat, elevation, length of run, etc.

You can't "add or remove TQ" from a tune. You can adjust the fuel, timing, duration, and fool some sensors to improve it some.

**But, the down side is the functionality of the vehicle driven as a daily driver. Something must suffer - cause and effect. Do you want Economy or a raging engine which can't pass a Fuel point or something in-between.**

After doing Racing Motorcycle Engines for eons (which actually started as a hobby in the 80's). I've come to realize that an increase in one often is a deficit for the other. The optimum is to find a mix that will get you up, shoot you down lane, maintain the run, and not "fall on its face" (pass the of HP to TQ curve) doing it.

The question you should be asking yourself is; Do I want to increase the TQ? And, if the answer is yes, how do I go about doing it AND maintain or increase HP. The next is.......... "how much money you got?".

Here is the equation I tell people I use to determine that:

$$$$$$=(HP&TQ).

There is no other way. There are many people who use the phrase "there is no replacement for displacement" False, doesn't understand! It's called MONEY $$$.

While I can, and have run a Dyno's for years, I'm not the one you want doing it. Setting up the sensors, and programming the inputs are an art form. And one size does not fit all. A dedicated Diesel Tuning Dyno resembles nothing of a Gasoline Tuning Dyno. Same for Aspirated or injected. Sensors and inputs must be changed and spanned for the particular vehicle if you're doing tuning.

I build the engine based on what it's going to do and just as importantly where its going to do it. - Weather, elevation, etc. Then, I take it to Richard who is the top guy on a Dyno. He'll program the simulations, and run it and make selections and opinions based on the data he sees. Anyone can run a WOT Dyno and print a sheet.

It often takes up 6 - 10 hours to "dial one in" and 30 runs sometimes. The good guys will run them at 5% or 10% throttle position increments each time for just one run. That can be 10 runs WOT just to get an idea of what its doing before even considering what might need to be adjusted or replaced.

You ever wonder why you sign a release form when you get a Dyno run? I've carried many parts back from a dyno run until I got the engine right. HP=Engine Stress / TQ=Driveline Stress. How much stress can one take before a nervous breakdown? An Engine is no different.
