Does anyone know the flow rates for GM injectors or roughly what BHP they will take?
I have a modified C16XE and am wondering if I need to change the standrd ones for something like red top cream injectors as it is dieing on full throttle. Could it be that the injectors can not flow enough fuel?

x16xe injectors are 165cc/m at 3 bar !c16xe part number a bit different but I think same flow cc. Maybe you can replace the fuel regulator

Thanks for that.
If my calculations are correct then 165cc per minute would be good for up to roughly 132bhp so I would be pushing it even if they were working perfectly, which they probably aren't.
I will try changing the regulator first and see if that makes any difference.

Changed the regulator and it made no difference.
Then changed the injectors for red top cream ones and it made things worse.
No idea why it won't run on full throttle.

injectors are good for 170bhp

you cant just change injectors, would need to be remapped to new injectors
