We spend allot of time and money trying every combination out there to make these 2.6 trucks run. Setups and dyno numbers aren't freely talked about in the pulling world. But I can say we made our round about goal of estimated 1200hp to the crank on 37lbs of boost 66mm/2.6 turbo
@@specializ20you want low boost. Boost is just a measurement of restriction, the less restriction, the less heat. Less heat means denser air, means more usable oxygen in a cubic foot of “air”. In “air” limited classes like sled pulling, where everyone has the same size turbo, the truck that’s winning is probably running the lowest boost, because that engine moves the most amount of air through the cylinder head. Making power the most efficiently.
can someone explain what these 2.6 guys do beyond a ton of fuel to get 4 digits from a 66mm single? i would assume cam and head are top of the list but im still struggling to see how a 66mm can move that much air
I couldn't tell you exactly what they do but remember at the end of the day, it's air and fuel that make power. That's all there is to it. Make the combo as aggressive on boost and timing as you want it to be and hope you brought enough. That truck sounded like it was turning some healthy RPM, too, so there's that part of the equation.
All sled pullers make power off a ton of fuel. Because pretty much every class bans injectables and rely on fuel and air only, they dump a ton of fuel and run super rich. Also more rpm means more air through the engine, the more air through the engine, the more fuel you can burn. So wind it up and pour the fuel in. Also injector technology has come a long way in making the fuel utilization way better than it used to be 5-8 years ago.
It's a 2.6" turbo inlet, but the compressor wheel is much larger. I work on some 3.0 trucks and their 3.0" turbos are bigger than my 85mm turbo on my car. And they are ball bearing turbos.
I guess the dyno graph is a secret too. 🤣. Here is the thing with knowledge. No one wants to hear it when you want to share it. The people who do want to hear it when you share, are not really able to use it anyways.
They do, it’s just they don’t have a hook up for every wheel base and truck configuration. You can see the exhaust vent pipe at the back of the vehicle for a standard exit exhaust system. And they have a hanging exhaust vent from the ceiling, but it either didn’t line up with the length of this truck/hood stack configuration. Or in a recent video a high horsepower hood stack truck blew it off and it fell from the ceiling, and they may not have had it repaired for this session.

Why do you run a low amount of boost?

I bought a new 06 Dodge 3500 g56 Been a great truck. Still loving it 👍🏻💪🏻🇺🇸
You can always trust a welder that uses an optrel 💪🏽
yes
@Firepunk Diesel
Where is a good place to start for doing a common rail swap? I have a 2nd gen and would like to see what it would take to swap.
What HP did you make or is that a secret ?
Have you done any mods to the G5600 ?

What hp did that pulling truck make?🤔💪🏻💪🏻👍🏻
It's a secret 😂
@@scooter313 But of course it is...🙄😒

Why the hell don’t you have an exhaust HVAC system? Are you guys insane?

This is a joke right? How are you going to dyno with dirty air lol
