Hey guys. Just looking to ask a question about this. And I didn't want to muck up PowerStrokenStang's win thread.
In his run, it seems that his truck is smoking good, then it shifts and cleans WAAAY up.
My question is, is this from ICP dropping? It doesn't seem like the load is letting the turbo spool more, although I don't know much about PSS's setup.
It seems to me that when it shifted, it should smoke MORE. Because of a bigger window to inject fuel from the lowered RPM. I'm just trying to learn, not bash anything.

Thanks Dave. That definately makes sense. I was just wondering if the ICP might have been dropping due to the lowered RPM's, but you know better than I do. I didn't evem think of the fact that he was on the stock bottom end.
not stock bottom end just stock rods, cryoed though. also def shouldn be icp, i am running a gen 3 and a brand new 17 degree hpop. it has always cleared up after the shift into 3rd.
When ICP drops smoke increases usually, as PW isn't a set thing exactly. PW is based on ICP usually, and increases as ICP drops to maintain the same fuel desired.
So, ICP drops, atomization drops, PW increases, mass fuel remains the same, smoke will increase.
Also, knowing matt, hes got a little fuel out at the lower rpms to keep the motor together.
A drop in icp will typically result in more smoke unless someone were to make the tune drop pw as icp dropped. that woudl get the icp back up however and clear smoke.
The charger is hitting harder once the load goes up (3rd gear) and I do keep the fuel conservative down low. The reason his truck runs so good is the fact that it is right on the edge of needing bigger nozzles. Instead of going with a 400% nozzle right away we (the collective of people that put work into Jason's combo) thought about doing something different. I think Jason's combo runs so well because we can run max pulsewidth in his desired RPM range and keep the exhaust velocity up and not dump fuel so fast and create better turbo drive that way. Next year there are a few tricks that should make his combo even better.
haha ya let the guy in charge of that stuff answer. one lil trick was ordered today, thanks dave. also dave i think you thought i said my name was jesse, its jason.
So Jason, is your wheel speed going up after the shift? I guess the reason I was so confused was because it didn't seem to gain a lot from the shift, but the truck is performing well, so it's obviously working for you!
