got a question for a friend of mine. he just recently bought a 91 with a 302 edelbrock heads f cam performer rpm intake 75mm t.b 42lb injectors and a powerdyne bd10 blower blowing 9lbs. his plans changed and wants to make it ito a track car. he updraded to a edelbrock super victor intake with a 90mm wilson elbow 90mm t.b 95mm maf fuel cell a100 pump anderson pmas system and a vortech ysi blower sumwhere around 14lbs of boost. his only concern is he dosent know if he should updgrade to bigger injectors like 60lbs since there is going to be a increase of air?

Needs to be run on a dyno with a wide band O2 sensor to monitor the air/fuel ratio.

Yup if the A/F ratio is correct he wont need the bigger injectors!

he could always get the bigger injectors just to be on the safe side.... As long as the car is tuned properly so the injectors arnt dumping in to much fuel it will be fine to use bigger injectors

I ran 42# injectors with a Vortech T-trim (19psi) with Edelbrock heads & stage 2 fuel system...Might need the 60#er's with the YSI SC, would not hurt!
