I am wondering if i need new injectors. I am running a forged 355 with ported stock heads and upgrading to either the big xfi cam or 847 and bumping up to the 150 shot. I have the walbro 255 fuel pump and trying to figure out if I really need them or not.

Thanks

You SHOULD be alright with the 150 WET shot. I have stock injectors with le2 heads and 847 cam and even though the duty cycle is alittle on the higher side, they are not maxed out. If I were in your shoes though, I would.

Yeah, if the duty cycle on your injectors is 80 or higher i think you should step up. Does the 255 lph actually cause more fuel to flow, or is it just so the stocker isnt maxed out?

keep what you have for now just turn up the fule press if you need more. the 255 flows more fule but theres no change in press unless you adjust it at the regulator. So if you add more press and bring down the pulse with the injectors are not maxed out and you get the same amount of fule. but i just dont think youll need bigger injectors.
