The demise of 2.6?

That is awesome that badger went smooth bore...not, I was going to pull this year with them but money in driveline means no money for new turbo, looks like outlaw I guess, harts is wanting 5500 for 3.0 smooth bore....I did ask them about converting an hx 60, they said 2k and would be under hp than their new one.....anyone else hearing the same?

Did they say what kinda of hp gain the $3500 is worth over the 60?

For that 2k upgrade. That with ball bearings? Seems to be these new smooth bore turbos won't live being journal bearing anymore. 1500hp at probably 80+ psi going to be rough on shaft speeds.
 
This 3.0 smoothbore turbo from hart's is nothing new. I wonder what makes a gt4202r worth $5500. Sounds like you could save a bunch of money if you bought the turbo yourself and sent it in for a wheel and cover upgrade. 150hp increase seems rather on the highside.
 
I know my friends 640ci Super Farm makes over 100 psi on the Hart's 3.0 smoothbore...he made 85 psi on his Precision with all Colberg upgrades 2-3 seasons ago.

They made a comment that they changed their exhaust housing and it is not the same as their tractor smooth bore .... not for sure if it a T6 or as the tractors a t4?

I heard the same thing from a couple other tractor guys, wonder what Weston will come up with and price range....he held his own last year with them guys or so I was told by a few reputable folks

The tractor smooth bore is limited by the turbine. The 3.0 smooth bore for trucks will be a lot bigger turbo all together that's the 3x3 superfarm turbos. More than likely same frame as what the 3.6 smooth turbos end up. Full billet center , dual ball bearing holset based.
 
I thought the turbo upgrade was to save money and use the same type of turbo?

I don't doubt that the ball bearing turbos will be more prevalent, but I think you will see smaller turbines and increased shaft speed. I am curious to see what comes out of the woodwork in the next couple months, how they all stack up on the track, and how they last.

from what I have been informed you sir are correct. at gordyville a few things were pointed out to me. seems the exhaust housings are the only off the shelf component being used.
 
I'm not a turbo guru. But from what I understand the 3" turbine is too small. A 1400hp engine to be efficient needs x size turbine to flow. A tighter housing on a big turbine makes more power. Same reason the big hx82s make more power with a g trim over a e or f. They just use a tight housing. I have been told a 3x3 super farm turbo lost power last year over what the 2.6 turbos being ran were.

In competition applications, I am not so sure that what we can use the common theories we apply for turbo sizing. I don't disagree with what you are saying, assuming that the compressor is not limited.

From conversations with builders on cam selection for the new turbos, I was told that the Hart's 3x3 is the only one at the same HP level as the old 2.6 chargers. I was also told that was will their smallest housing. Hard to imagine how fast they are spinning them.

Take all of that for what it is, hearsay.

Same here. It's going to be interesting I think. I don't think peak power will be the thing to worry about. I think finding a turbo that doesn't need rebuilt every 6 passes will be lol.
