injector/turbo sizing
Need some advise from the performance guys here, truck in my signature, currently running 300/200 injectors (new not remans) with BG S468 turbo. I am having a haze/smoke issue, pretty much any time I am on the throttle at all. I am beginning to wonder if the turbo is enough air for the injectors. The truck runs great,no issues at all even towing,just the smoke. I am running DP tunes but have tried PHP,Gearheads,and No Limit tunes.No one has been able to get it to clear up better than Jody. I know the injectors are LARGE for street use but should be tameable..
My question now is, with a new build, what size injector works best with the S468? Fire away

You're wallet whipping again? Same truck?
I don't see how you can clear up a 200% nozzle. I would think it would be physically impossible to get the good atomization you need for a clean burn - and hybrid is worse because it has a 5:1 intensifier, instead of a 7:1. If everybody struck out, with at least 2 of them being live tunes - you might have to yield on this one. You may have another form of Tuglyitus - but mine manifests itself in the form of abhorrence of vibration and knocks.
You already have the mondo HPOP, you may be able to get non-hybrids with a 200% nozzle. How's your LPOP? Can you settle for the anemic power of a 100% nozzle after having warp speed at your foot?

Hey Rich, Its been a while. I have checked in several times but haven't been posting. Surgery,new house, well things have been busy. My baby has been setting for a while (inside of coarse).
I have been not wanting to accept the nozzles are to big but that may be the issue in my case. I do know of several people that run these with no issues.
Yea,same truck. I was kicking around selling Godzilla but fear of being laughed at(pricing) may have changed my mind. It's not so fun anymore, all the Dodges and Chevys in this area won't play with me anymore.
The LPOP is a mellings and pressure is good.
So back to my question. What injectors would take full advantage of the S468? Wanting to keep as much HP/torque as possible.Definatly don't want to go from Vett to VW.

Yes, haze at part throttle, interesting you bring up the exhaust housing.
Before the 300/200 injectors I used the .90 exhaust housing it was a blast to drive but I felt the back pressure was to high.Currently,I am using the 1.0 housing and it tamed the back pressure issue. maybe I will reinstall the .90 housing and see what that does.At least if that clears up the smoke it will give me a direction to explore with a larger wheel on the intake..
I do believe it is fuel, no signs it could be anything else and everything has been looked at several times.

Worst case, external wastegate it.

That's just with a little itty bitty 38R. 0-60something in that vid. Hardly a wisp of smoke. Runs like that all day long.
200% nozzles can run clean regardless of the turbo, assuming there's no actual problem with the injectors or the truck.

the .90 housing is installed, what a difference, the haze/smoke is all but gone. Now, there is a new issue, whit the cruse set and pulling a hill the truck starts skipping really bad.I can smooth it out with the throttle but it is there...I am thinking, now with the smoke cleared up,the tuning needs tweeked.. Now to order one of those fancy waste gates from Irate..
