how much boost can u run on the stock injectors with a whalbro 255?

 

Not very high. Also depends on tuning.

 

have any numbers?

 

There was a great calculator that I used to figure out how much fuel I needed. Anyone have this?

I woulndn't run past 12lbs on the stockers. The last motor I saw blow was at 14psi on stockers. I said 13 in an earlier post. I looked the info up. The injector duty cycle was at 93% at 13lbs w/ a good tune. cold night=boost spike=bye motor.



Its not worth taking the chance.

 

so he had a walbro 255 with stock injectors? if thats so its alittle hard to believe I ran 12 pounds on stock pump and injectors at 11.8\1 air fuel but i had it tuned for that temp range and i have a plx wideband running closed loop on my aem so it keeps my air fuel mix realy close to my tagett air ful ratio is.

 

And technicaly you can run 120% duty cycle but thats maxed

 

calculator is great thanks lots

 

turbovr6 was running over 16lbs of boost and his car ended up blowing form a bad coolant seal.... and according to him, he literally tried to blow up the motor
