Black smoke is cool at the track, but not cool on the street. We are now in a position to reduce and eliminate smoke from our trucks. So with that said, what would everyone do to design a smoke free 350-400hp from our 7.3's. Please include all parts and why you choose them. Maybe this thread can help us in the eye of the non diesel public.
If I could get a gt 38r an mine and a sensible tune it would be just about smokeless.Tip in on the tune I have is kinda dirty. I could peddle mine with out much smoke.
mine is pretty smoke free in my daily setting and will still make 40 psi of boost, unless i smash the go pedal before the turbo is in its happy range. :shrug:
It can be done..... You can make an 80% nozzled hybrid be almost smoke-free but there is room for improvement still for the guys that have the drop in turbos. I have some things in the works to improve upon the tunes I have now. Let's just say they will be raising the "bar" on the 7.3 tuning (that's your hint). Hopefully I can have this available in the next few months.
No, there is hardware limitation on the trucks. Guys that run more than 25lbs of boost HAVE TO overfuel right now at some point to get the boost up. I am working on something to allow linear fueling up to a higher boost level. Sadly, this will only be for the super duties and not the OBS trucks.
I have a set of AC injectors and a Turbonetics drop in and DP Tuner made it very nice with live tuning and did away with most all smoke except a couple settings up on high
I know my economy setting is smoke free. The others are easily kept smoke free, even the extreme really. I have a modded h2e, Hybrids w/100% nozzles, termy pumps and Wildman tunes.
Higher-rated MAP sensor with programming to eliminate 24-ish PSI de-fuel?
I always wondered why we had to throw a regulator in the MAP line when other engines have been just programming out the limitation and using higher-pressure MAPs..... Heck, our TDI has a 3.5bar MAP and the programming for it, why can't a SD?
Is that what you're up to?
I think the best way to do this the like the Procharger and Turbo set up that Empire did for Imelmo's 6.0L. Instant spool off idle and then big boost from the turbo for the top end.
This is why my DD truck has compounds and one of the reasons why my project truck will have two stages of forced induction. The smoke was "cool" 5 years ago.... now everyone does it. I remember laying some thick ass smoke down back in the day especially when testing and trying something.... Now the only place for it is at the track. Its a complete waste on the street.
