How do you guys know what size injectors you need?
 

Is there a formula for success or a chart somewhere? My concern isn’t getting injectors too small…its getting ones that are too big and running pig rich.

i believe this has more to do w/ the duty cycle of the injectors-... for instance you could have a huge injector but only allow it to squirt the stock amount of fuel because it's not working at it's full potential-...



someone else wanna chime in and let us know if that's correct?

Here ya go:

Duty cycle is something to be aware of too. To large an injector is going to cause some idle and cold start problems. When injectors are scaled down to like 3-4% of their duty cycle they are not very accurate ... and that varies between mfg and even injector of the same mfg.
