Taming 350% injectors for the street

[EverydayDiesel]

Has any one tamed 350% exergys for street use? Is this possible?

For starters, how much should i cut the pulse width table down?

Any tips are greatly apprecaited!

Flow sheet is very helpful with tuning. Comparing stock vs injector flow sheet at mentioned set points can point you to the answer for your question.

Thanks for the reply. Tuning these injectors IS possible with good street manors? I think exergy will provide the flow sheet but I will make sure before I order.

Also with proper tuning, will these be mileage killlers if I can control my right foot?

Setup dependant but likely they will haze...

And again for mileage, I wouldn't count on them being great

what makes 350% exergys not daily drive-able exactly? Smoke? Surge?

I have a completely built motor, qsb pistons, carrillo rods, girdle, dual cp3's, 625, hamilton springs/cam/tappits/push rods etc
The only 128* spray pattern that exergy makes is 350% and I am trying to decide if i can handle these on the street. (i called around many places but did not find any with the correct spray angle)

QSB pistons? Pics?

Typically QSB are a marine bowl design that will accept the 143* BMS nozzle.

To my understanding you CAN run 143* but the hot spot lines up with the weakest part of the piston. Also I read that people like lavon have run 128* with great success and from what I understand it is easier to tune.

So what makes 350%'s not streetable exactly?

Sorry I was thinking QSB 6.7, not 5.9. Too early

can anyone answer why a 350% would not have good street manners?

They can have good manners, but they will haze
