Mid-Tenn Dyno in March

[DavidTD]

Well, first I see why there were so many Dodge trucks there. :-laf It never occured to me the Mid-TN chapter even had a thread started about Beans. It was great to finally meet some of you.



Mike and I had a blast. We intended on staying last night, but due to some unforeseen reasons, Mike needed to be home today. But we started with Len's truck at 8:25am and finished with Josh at 6:32pm with an hour lunch to enjoy that great food. 32 trucks and 135 runs.



Len's Dmax rocked!!! Mark's truck with the new HTT rocked. I loved the two top trucks that were . 1hp apart. And Meachum can make sure I get this right, but I believe they were set-up the same.



I got home about 1:30 this morning and was thinking about all the beer drinking and lies that were being told all the way home.



(my guess a tire store will offer you guys a "group buy" Monday.



On Edit - I started a thread in the competition forum with numbers. Or you can go here Dyno Results

 

[DavidTD]

Yeah I agree, thanks to Mr. Dunbar for an awesome dyno day!



I am going to put together a spread sheet for work, so if you guys could send me all your dyno numbers, what you were using at which numbers and all the toys you have on your truck - even turbo sizes I would appreciate that bunches. I am not wanting to spread this around, just use it so when a guy calls up and asks some questions I can have this as a guideline to help them get to some good numbers.

I can send you my Excel spreadsheet to get you started. Then when you add the info you can send it back.

David,

Absolutely. You scratch my back and I will itch some more... ... I mean I will scratch your back. Right? Email it to me whenever you get a chance at

-- email address removed --



I was the big ole ugly guy with the blue mirror shades... ... that way you'll know who your messing, I mean dealing with... hahaha



Again awesome dyno and great hard work from David and Mike. Thanks again you too! And tell Mike thanks too!

i made 514HP with smarty on number 7 and no other boxes on. and made 537HP no smarty and tst on #7. smarty done a pretty good job i wish i could of dyno with no smarty or boxes. but david give me a couple extra runs already. i made 532HP with smarty on 7 and tst on 7 so with the both of them i lost 5HP than with just tst. :

 

[WadePatton]

THANKS EVERYBODY! David and Mike first--it was great to have Diesel Truck guys running a dyno for a change. Great to see folks work hard and smile at the same time.



The Bean family put on a helluva spread food, beer, diesel--a few marks in the road :-laf --GOOD STUFF! Those that missed--well YALL MISSED IT!



Let's do it again in a few months! Maybe I'll have my other 12v ready to go.



Hey David, any chance you can stick my 12v sheet in front of Jeff and see what he thinks about the mysterious dip in power? Next time up that one will have a different fuel plate and a wastegate--at the least.



Gotta run--but mildly, wife just called and said "Don't leave marks in the road when you leave, there's a cop sitting with his lights off just down from our shop. " She's a good un.

 

[HeavyHauler]

So what truck was Gap running? Did he bring 'Ol Smokey or something else?

 

[Piston Slapper]

It was ol smokey. I knew she wasn't feeling to well, and was really expeting her to be down about 100hp, but wanted to see where we was at anyway(TC, turbo and overfueling issues). I was guessing high 5's to mid six's and if we got lucky and she's just ran well, about 750hp. She only made 40lbs of boost and didn't get over 1200. She wasn't even working hard... . I don't think it got loaded up enough, but still was expecting more... . oh well, I've seen this happen twice before on pulling trucks. They just don't make the power on the dyno's sometimes... .

 

[AndyMan]

But DANGGG!!! She sho did sound good roaring up there. Gave me goosebumps. Best sounding truck for sure. I tried to enjoy it, but was worried about some random part flying off and killing me.



That's a big 10-4 on the overfueling. That was the absoloute THICKEST BLACKEST smoke I've ever seen. Once she got way way up in the RPM, the smoke quit, and it seemed to be stumbling. I'm limited in knowledge, but I'm with you on the "putting the fire out" theory. Seems plausable and likely.



EDIT: you need to put a plug in the bottom of the stack tubes so that you can drain the raw fuel out after runs like that. :-laf

i made 514HP with smarty on number 7 and no other boxes on. and made 537HP no smarty and tst on #7. smarty done a pretty good job i wish i could of dyno with no smarty or boxes. but david give me a couple extra runs already. i made 532HP with smarty on 7 and tst on 7 so with the both of them i lost 5HP than with just tst. :

Steven - do you have any ideas as to why you lost power when you ran the Smarty with the TST? This is kind of bothersome. What turbo(s) are you running now? Could it be that you didn't have enough air?



Are you still running the old Mach 5s, or have you upgraded?



Any certain reason you stuck with Level 7 on both boxes? Just curious...

Like Mr. Dunbar said--two ways of doing the same thing. "Boxes max out the VP"-- two boxes--can't max it out twice. Or something like that.



What troubles me is that my last run was "Smarty only" and it must not have taken the right setting. It only made as much power as my injectors do alone. I think I got the Smarty timing, but there was no real help to the VP. I took it down the road with that setting. Timing was there, power wasn't. Like to play with it again.

 

[HeavyHauler]

Alright, but what about the gains that you get with stacking boxes (TST and EZ)? You're not supposed to lose power when you add the EZ to a truck with the TST box.



As I understand it, the Smarty essentially does the same thing as the EZ but with dynamic timing. And the Catcher softwares clearly alter the fuel curve. The Smarty and EZ add fuel by holding the VP44 solenoid closed longer so the high pressure from the pump will hold the injector pop off valve open longer, dumping more fuel into the cylinder. I thought this was an ECM operation.



I'm not 100% sure on what is going on inside the VP44 when the TST is cranked up, but I thought that the power added from the TST came from the electronics on the VP44 itself, not from the ECM.



I guess what I'm trying to say is I didn't think the boxes did the same thing. If they did, a VP44 truck would never break 600HP if it wasn't possible to stack boxes like the TST and EZ/Smarty right?



Then again, we may have uncovered a flaw in the Smarty, but I sure hope not. Marco made it sound like the two were quite the combo.



Could it be that Smarty doesn't work and play well with others? :-laf

 

[WadePatton]

Well, I don't _know_ squat about them boxes, but giving it a little thought now. (danger).



So maybe the Smarty simply does through the ECM what the others do by tapping the wire. And has access to more parameters. Like I said, I'd like to play with the Smarty and no box--to find the right setting. By that time on dyno day, I didn't have time to monkey with it enough--my 24v didn't get there till late and the beer started flowing early.



Stacking was the rage when guys wanted to add timing to fuel-only boxes. Seems to me that Smarty can do it all--with no wiring to fool with. I want to like it. And yes, I haven't read any of the thread-so I'm way behind the curve.



But then I'm getting out of the 24v bidness.



On to other news. 12v head is off-dang monster that it is. Now for the stripping, cleanup, machining, lapping, running down all the odd parts, etc.



And I figgered out that maybe my fuel filter was restricting flow in my 12v runs.



Carry on.

 

[DavidTD]

Here is what I have been told whether right or wrong.



Changing the VP44 operation through the can-bus (EZ,VA,or custom ECM) will allow operation of the VP44 to the maximum allowed parameters as established by Bosch. Meaning, if there is 60hp worth of fuel available from the VP44 ABOVE what we get from the factory, ANY of these methods will get it if programmed to do so.



By tapping the wire of the pump, you are bypassing the factory electronics, and forcing the VP44 to work outside it's designed limits, but DO get more fuel than the Bosch limits.



To fully test these boxes, you need to do more than we did at Beans. You need cool down time between runs, you need to test on a truck with enough air to support the maximum fuel provided etc. In many cases, I have seen big injectors produce max or near max power with a Comp on level 1. Anything above that and the fuel delivered cannot be burned. This could be the case we had with Stephens truck, but to be honest, I can't tell you what his smoke level was and so on.



His two high runs were basically the same. While one was higher but it was due to a small hump in the line. But basically it was the same power.

 

[Crazygator]

I think whats happening is that the Smarty will work great with modules or lower powered boxes, but when you go to the higher hp boxes they conflict to some degree, or maybe they fight to control the same parameters and therefore you lose power.



I do know that most of the good Smarty dyno numbers the hp lines where all tight together and did not fall off until 3400 or more. So it seems to get the hp up there faster and hold it through higher rpms.

 

[WadePatton]

Yall listen to David. He knows more than me. And has seen it ALL, I'm sure.



So the 12v head is cracked through all the valves seats. :{ Anybody got a good one handy?

 

[Crazygator]

Wade,

You wanting to know where to get good head? :-laf :-laf



Hope you get her back together soon and sorry for your crack find! :{

 

[DavidTD]

Yall listen to David. He knows more than me. And has seen it ALL, I'm sure.

You can listen, but just take it as one person's opinion based on what he was told so it could be total BS. :-laf
