How far is 42# injectors generally good for?

[02SilvermistGTP]

How long do the 42# injectors usually take you say with a cam and e85 before you have to upgrade to 60#?

Usually around a 3.2 pulley is where they max.

Ah might as well buy some 60#s then, I was hoping it'd somehow get me down to 2.8 on the gen3

 

[GTPpower]

Yeah, you should be running 60's at that level.

42's would work if your on gas only. mine run at 70% so add 30% more to them and maxed out. 60's for sure.

I'm at 90% duty cycle on 42's with E85, but my elevation is 7000 feet, so I don't need near as much fuel as people at sea level. I would go with 60's.
