the major problem I see is the t3 flange. my stock turbo and manifold has a t4 flange. how am I sopposed to compete with a smaller than stock flange?
Heres some input for you, DETAILS!
• Altering of a turbo housing to accommodate a smaller foot or base will not be permitted.
• 2.6 class: Exhaust housing should be OEM for the specific vehicle or T-3 type mount (1.75"X3.375" bolt pattern). T-4 and T-6 type mounts not allowed, waste gates are allowed only if the design is internal to the turbine housing, spacers and/or adapters between the turbine housing and exhaust manifold are not allowed. The turbo must fasten directly to the exhaust manifold.
• Map width enhancement is allowed. Maximum map width .150”. MWE groove must be inside neck area where intake covered is measured at 2.6"
• Compressor wheel must protrude into 2.6 inch bore, no steps allowed in the cover or compressor wheel, no bushings allowed in the compressor cover, Intake housing to be no larger than 2.6 inches at the face of the wheel. Maximum OD of the compressor cover may not exceed 8.5"
Exhaust:
• 2.6 class: exhaust must exit the turbo through a pipe no larger than 4" OD which must extend to the rear of the transmission bell housing before changing size.

Just asking, who ever said that 2.6 is supposed to be an "entry level class"?
Or is that something we all invented in our heads?
Because I don't read "entry level" in any of the rules.
Isn't "entry level" what work stock is for?
Well said... 2.6 should be the next 2.8, offer 3.0 and then a superstock class.
The local classes can have a 2.4 or even a 2.5 that won't allow anything larger than an s300.
If a superfarm tractor can make more than 1000 hp on a t4 non gated charger on a 450 ci + engine spinning 5000 rpm than its not gonna bung you up that bad.
Exactly.
Not NADMs fault the fairs who are adopting National 2.6 rules for their local entry level class are getting pounded.
And who pushes the Fairs to adopt the 2.6 over WS? Local guys with a 66 who want to beat up on the true stock stuff.
Pick the right class to follow for the trucks you have locally.
This is what PPL uses for Super Farm.
With obvious changes to sizes listed, and exhaust teching issues in pick ups, how would this affect the classes/trucks that are out there pulling now?
10. Turbos:
10A. Altering of a turbo housing to accommodate a smaller foot or base will not be permitted.
10B. Exhaust housing and exhaust manifold bolt pattern shall be no larger than 2.75 X 3.5 inches.
12 Intake:
• Map width enhancement is allowed. Maximum map width .200”. MWE groove must be inside neck area where intake covered is mearsured at 3”
• Compressor wheel must protrude into three inch bore.
• Intake housing to be no larger than three inches at the face of the wheel.
13 Exhaust:
• All turbine wheel blades to protrude into three inch bore. All air must exit through 3” opening.
• Turbine wheel exhaust blade to be no less than 2.90” in diameter at intersection of turbine wheel face and tip diameter.
• Turbine housing to be no larger than three inches at intersection of turbine wheel face and tip diameter.
• Exhaust housing will be measured at intersection of turbine wheel face and tip diameter.
14. No waste gates will be permitted.
15. No variable geometric turbos permitted.
Will a Chevy have to run a stock pedestal?
Damn Chris what put you in such a fine mood?LOL I know what your saying, pull whatever classes you happen to fit in and win if you can.
Then have someone ***** about my truck because it has a cummins in it. LOL
I'd say more but there are times I know when to keep my mouth shut.
