This is on Floor it Diesel's Dyno Dynamics load dyno, with my monster wheels and tires. John said I could count on an additional 40rwhp if I put a set of stock wheels on. There was no RPM signal hooked up so there is no torque #'s from the dyno, but you can calculate it manually.
First pull was TST twins program on 5/5, Bully Dog on the Crazy Larry setting, and the EZ on 3 (high). Result was 526rwhp
Second pull:
This is with the Bully Dog on the Crazy Larry setting, the TST twins program on 7/7 and the EZ on 3 (high). Result was 541rwhp
Third pull:
This is with the Bully Dog on the Crazy Larry setting, the TST twins program on 7/7 and the EZ on 2 (middle). Result was 524rwhp

The amazing thing was that the HP peaked at 2200rpm and only fell off 10 hp by 3200rpm! It was super smooth and consistent. If you figure the torque manually on the 2nd run it was 1291.5!!!

 

Sweet! Nice numbers.

 

bout time for twins id say

 

Nice numbers...

I think it is interesting that the TST Twins 6-4 and the Ramifier 50-60% can make 550 hp... and it takes a triple stack and the TST turned up higher to make 541??? What were your EGT's? Maybe there is not enough air in the equation?

On a serious note...maybe it is an indication that there is a fine line when tuning the fuel on a 3rd gen...or all trucks are just different? Have you tried dynoing the TST alone with just the EZ? Tommygun has made over 500 with a SO and that configuration...same turbo.

 

Nice numbers.

That is interesting, every time I tried to run my TST over 4/2 and Crazy Larry I threw codes and got very hot quick.

I did dyno with TST(twins) on 7/7, EZ on 2 and BDDL Performance program loaded. This produced 522/930 numbers. Any higher combo lost either hp or torque.

I did dyno with the TST 7/7 and EZ on 2 492/870 numbers.

I never tried Crazy Larry, TST and EZ on the dyno, just did not think I would see more that way. And besides even if it worked on the dyno doesnt mean I could run it at the track safely.

 

Dyno Dynamics dyno's are known to read around 10-13% lower than a DynoJet... and my tires are worth 30-40rwhp loss. The EGT's were between 1350 and 1400 every pull. I can tell a huge loss in power if I load the stock setting on the Bully Dog and just run the TST/EZ, that's why I didn't dyno it like that.

 

Are you getting your EGT etc from the Outlook monitor or do you have guages?

 

EGT is on the TST box, boost is Dipricol 60psi on the pillar

Also, the "SO" is all in the computer, once you put a TST/EZ on it, it's the same as a 305/555 with TST/EZ

 

Whitesport600...not picking...just trying to brainstorm a little.

A TST/EZ will not turn a SO into a HO...there are major differences other than fueling maps.

My TST EGT reads 100 or more lower than my other EGT probe. I have 37" tires, smaller diameter wheels (so I am assuming my combined tire and wheel wieghs more than yours), and my dyno's are on a Mustang which read lower than both of the others you listed. Just food for thought...

What was your boost? Did you have you TST set to defuel at 1400 or higher?
What was the elevation?

Maybe I should put some stockers back on myself to hit 600.

 

I Can't relate to much but I have 37" mtrs on H2 wheels on my Jeep and they weigh less than my 20s and 33"s inch Nittos...

 

cquestad---- So what else is different on an SO that would make a difference in power, the head is the same, the cam is the same, the rotating assembly is the same. Aftermarket turbo, so that's not an issue. Are the injectors different?

To answer your questions: My boost was at 48psi, the TST was not set to defuel at all, and the elevation was slightly >1000ft.

 

the pistons are different but I don't know what else is?

 

That's just heat coatings though, no HP advantage, just capable of sustaining higher EGT's longer...

 

Guys, HO's have oil jets on the pistons or something like that for additional cooling. I think that just slows em down . HO Pistons have a ceramic coating to raise the melting point of the pistons. From everything I've read, they need all this because they run hotter at the same hp/torque than SO's do. ks

 

WHen you say tst twins do you mean twin turbo? or twins program?
