Hey guys I was wondering I have basic boltons on my hawk and im about to finish installing my nos plate kit and im gona go with a 125 shot now my question is when do you go with bigger injectors I believe the ones on there are 28lb stock do I need to go bigger lmk thanks

Sounds like your going with a wet system, so your stock injectors will be just fine with the bolt on's you have. Your fuel pump, on the other hand, may not be up to it.
I would look into a Walbro pump along with a hotwire kit to replace your stock unit.

Cool already did that got me a racetronix pump and the hot wire kit also ok nice so when other guys go with bigger injectors im guessing thats more for forced induction like big horespower engines

Usually when you add a set of heads and a cam you will need bigger injectors.
A dry nitrous system requires bigger injectors as well.

Well since you have bolt ons and a cam you might be close to maxing out your stock injectors right now. You might want to upgrade

So what maybe some 42lb

42's would be great, but you will need to adjust your tune of course. You may or may not be close to maxing your stockers now, but the only way to truly know would be to put it on a dyno
