Like a mid 13 or something. It was worthless
On fuel with a t4 housing. WTF was I thinking .

Do you have the 71mm exhaust wheel if you do put a .76 t3 and a 44mm wastegate

 

[SSpeeDEMONSS]

No...it won't even do a 2wd burnout Lmfao!

sounds pretty useless for a street setup. time for a smaller divided, wastegated housing. maybe a diverter valve too.

Laggy, T4 and a sub 1.0 housing don't go together. Is it smoking like a train trying to spool or something? Too much fuel down low?

How on earth does a little t4 with a .anything housing not damn near make boost at idle?

A 6.0 is smaller, but not that small. Is this common with 6 liters?

 

[Donzimama]

I dont know what to tell you charles, it needs a t-3 for sure. Yes Craig that's what I am doing with dual gates and a 483 over it. In a reg cab.

Its actually pretty common, alot of the dodge guys dont like the .80 housings because its laggy, open housing is why they say, so most go to a t3 divided and they light fast as stock... i cant explain it but thats just how it is.

Stainless exhaust manifolds help alot with spool up
I'm running a 66/74/.90ar divided on my 6.4 and spools up great we even towed whitey to the track a few times with it

 

[bdavis91]

interesting how it made 723hp with nitrous on the dyno but going by the HP calculator...it says it's between 660-690 like you said depending on the speed or the time with nitrous also.

He only ran once with the spray and didn't want to kill the tranny...it could easily get into the 11's with this setup if it could spool instead of sit at the line smoking if he had a built tranny lol.

 

[Dieselcraft]

Congrats bro. Happy to hear you made it to the track. Now get it dialed in lol

yeah maybe. trap speed says otherwise. i guess if he sprayed a lot more. he needs at least 111-113 to get to 11's. his current times say his 60ft or 1/8th mile is strong. but the slip will tell the tale. great start no doubt, but im guesing a tranny will be in order soon

 

[Donzimama]

Who gives a **** what the calculator says. The truck tapped 4k 3-4 times before shifting 1-2 and 2-3 lol. This is going in a reg cab soon anyway with a tranny, just wanted to see what she would do before it gets torn apart again.

 

[Dzchey21]

Yeah i know what your doing, just dial it, then switch it, make sure the power is there before the switch

lol... get some, and a big wallet!! good luck buddy!

Are the trucks that feel laggy smoking heavily trying to build boost with the tight t-4 housings? Cause that will make any charger a pig.

If not, nevermind. Never thought a t-4 would be laggy on a 6+ liter engine.

 

[Chris]

Yes. those that run tunes that do overfuel make it even worse, but fact of the matter is a 6.0 does not like to spool chargers well at all. If we had direct access to the pw tables that would help things too imo.

has something to do with the housing, i dont know what but i have heard/read many threads stating how laggy a t-4 .80 housing is on a cummings CR, or 12v
