Dyno numbers for an 03 SO

[driverno8]

Not sure about the calibration thing. I'm really new to dynos.



tommy - If they went off the pink wire, the rpm's would be more accurate, right? Well would that effect the hp numbers too? Also, you're sig says EZ level 1. Is that what you were on when you layed down those numbers? Our trucks are pretty close to mods I think your turbo might be a tad bit bigger, not sure. I was actually going to put the EZ on 3 today and see how it feels. The 405 hp number I layed down was TST 7/7. I did try 6/8 and it was about 20hp less. (381hp) Thoughts?



Edit: Also, what gear are you in? And is your tow haul off? I ran in 3rd with tow on because of the lock up.

Regarding the SO engines, if you put the same box on an HO and SO will they show the same HP gain and still the HO will have more power, or will they both have the same HP with the box on?

 

[driverno8]

I'm not sure. I've heard you can get better numbers out of an SO and that they are more buildable. Not sure how true that is. I've also wondered the same thing about boxes and the SO and HO.

Really the rpm tap is the TQ numbers only... The hp are made by the movement of the wheel under your trucks tires... (from what I understand)



I have a stock turbo... so yours is alot bigger/better - The problem is that auto trans behind your diesel (sucks a little power IMO)

And I dynoed in 5-gear (OD for me) - And yes, that was EZ on level 1



Depending on the truck, Sometimes boost is hard to get on the DYNO, esp. with your bigger turbo... And without boost, the tst will NOT fuel to 100%



cya!

He's still running the stock turbo, your HTB2 will flow significantly more air.



As for boxes on SO vs. HO, the SO's tend to respond to them better. They'll still generally dyno lower than a HO with the same box but the percentage increase is much higher because you started with less.



The best I can figure on the dyno calibration is that they didn't have any kind of RPM pickup so they ran the truck up to 3k, told the dyno software that was 3k and had it back calculate to figure rpm. This would work but be less accurate than actually measuring it real time. It doesn't account for errors in your tach's accuracy, slippage on the dyno, etc.

I think with the JUICE/TST and others you will have same gains (+60, +140, etc)



But with the Downloaders, I think they would make the same HP (since the programs replcaes the factory info) - SO/HO = 350hp



maybe...

I'm with you 100% on the boost. On about the 12th pull he I asked him what boost numbers he was seeing. He didn't know so I watched him. He hit about 20 something. Well of course the numbers were low. The next time he power braked it and go it in the high 30's and spiked at 40 something. The hp number jumped up quite a bit. I want to take it someplace else. If you're hitting 437 with the stock turbo, I should be higher then 405 with the htb2, the cam and head work.

you should be near 475hp or more I'm betting --- With the truck in OD and a switch to hold the trans in O/D and tq convertor locked-up -- The load should make boost more easier to get

I suggest trying it with the EZ on 1 or 2. I've found higher pressure to be very taxing on the CP3. If you don't have a pusher pump you're definitly running on 0 fuel pressure at the higher EZ settings. I made my numbers with the pressure box on about 1/3 (tough to tell with a Ramifier), that's similar to an EZ level 2 I'd guess.

Fuel shouldn't be a problem. I have an AirDog. I just put the EZ on 2 and am going out for a drive. We'll see if feels different. As for the Trans. I was told to leave the OD/Tow Haul button on. (So that would mean no OD I guess) That's what we had it set at. I don't have a way to lock up the tq. The ATS Triple Loc with Valve body will allow me too but I need their commander set-up. I'm not going to do it because honestly I don't have a friggen clue what the lock-up thing is. I can't tell if it's the gearing or the TC when shifting. When we first dynoed at Scheid the tow haul was on when it was on the dyno, that's why I did it this time. I would love nothing more then to hit mid 400hp range. I don't see why I can't. I really think this dyno guy was off on everything. Not just the tq. Gearing is 4:10's on 35"s. Should put me right equal with 3:73's

 

[SRadke]

35" tires will hurt you on an inertia dyno. Extra mass to spin up to speed. I don't know how much but I hear it's close to 10% for the extra wheel of a dually.

Scott,



Just curious as to how you were liking the new Flux injectors? I know Don M is saying he has these figured out, and if he does, I'm all over it. Just curious.

He's got something figgured out alright. I'm making more power with my max temps down 200°. I'm also seeing slightly better economy but nothing to brag about. Also less smoke than the stock injectors I believe.

I did bolt my stock tires on for about 10 pulls. There was no difference in hp numbers between them and the 35"s. Not sure if it's becuase it's a dynojet or not. I put the EZ on 2 and drove her around yesterday. It feels the exact same as level 4 only it smokes. When it was on level 4 it didn't smoke at all. About as much as stock. I did leave the TST on 7/7 because that where it feels the best. It starts to fall on 8 and I can feel that 7 is more powerful then 6. I'm going to try EZ on level 1 and 3 and see how those are. But I think there's not a reason to go back up to 4. I also have a call into another dyno place, one that specializes in diesels. Should know more today.

 

[JCleary]

I would think that a load-type dyno like a Mustang would work better than a Dynojet, as it lets the motor spool much more slowly (In my limited experience, being at only two dyno events). This would allow the turbo to build needed boost to get the big numbers, eh?

I have been told that different dynos will give different results. Electronics can break down over time and over use. Which I believe. I work on dynos that test the helicopter motors for the Marine Corps. We have two squadrons that mirror each other with the same test cells. One unit can dyno a motor on their cell, get the results and then go to the other unit and use their cell and they could be + or - 100 HP. On a T-64 motor for the 53's, you can spray water on the motor and clean it and can pick up 17-32 HPs. (when it's cool of course. ) Again these motors put out from 1800 to 4400 HP, depending on the different sized motors tested. A dyno is a dyno, it is all math and results from different tests. I plan on going down to Wilmington sometime shortly to try a different dyno. I am happy with my results, but I want to try it with the RAD device to see what changes I can see. Plus I want to take my EZ down a notch to see if I was getting to much fuel. With my TST on 5/5 I was putting out good shot of the black stuff. Then on 7/7 it filled the room, even with a hose going to the outside. If it is too much fuel, it might be time to take the turbos up a notch.



Plus I was getting 40-44 PSI on 7/7 with the TST. Air for me was not a problem, the Super B spools up nicely and evenly.

 

[driverno8]

I'm with you on different dynos produce different numbers. But the dyno I was on wasn't giving me any torque numbers. The torque started to read on the down side of the power curve. Funny. My TST on 7/7 and EZ on 2-4 doesn't smoke like I thought it would. I ran the EZ on level 1 today and she smokes but I can feel a power decrease between level 1 & 2. I'm going back to level 2. Levels 2-4 feel the exact same. 2 just smokes more. Weird how lower the number the faster it feels. Question. If Level 2 EZ equals 50 hp. And the TST is rated at 150 hp on 9/9. Then how are you guys gaining over 200 rwhp with the TST on 7/7 and the EZ on 1? Am I missing something here?

Thats a good point... There is a point that more fuel will not make more power, and a point that the Rail cant deliver the fuel that we are asking for...



Did you do a stock run?

Almost every time I dyno, I turn the TST to 0/0 for a run, so I always have a baseline for the day



ON A SIDE NOTE:

I am starting to wonder if my truck is a freak or nature, Heck I have a dyno day this saturday, and even though my truck is having some "hard-start" issues (maybe injectors,etc) -- I refuse to take it in, because for some reason this truck is repsonding to the stacked boxes like I would have never guessed - And I dont want to jinx it before the big day :-laf

 

[Lonestar]

Hey TomeyGun, I'm just glad I'm not the only guy out there running TST/EZ stack with the STOCK turbo



I hear of all these guys blowing theres up and I can't make mine go BOOM. I keep hoping it will so I have to get the twins, but it won't :-laf

Tommy, have you put that pusher pump on yet?????
