How much power can 24# inectors support?

 

N/A or forced induction?

 

N/A mine kept up with 350rwhp but were running lean up top.

 

You got 350 rwhp out of 24# injectors? Damn! My 30#ers are struggling with a mere 330 rwhp. At 330ish rwhp, the injector duty cycle is at about 84 - 85% which is about as far as I dare push them before getting larger ones. That's why I use a nitrous wet shot to give me the extra 100 or so HP.

Of course, this is with forced induction so that affects the BSFC, but still, LoL.

 

Like you said, you get more out of injectors NA than boosted.. when you have to push your afr down to 11.5 - 12 while under full boost... you tend to burn a lot more fuel

 

24# injectors will keep up with a well built 302/306/308 motor... but will become slightly small on a 331-347 combo.

Im still debating on weather or nto to run 30# injectors, or 36# injectors with my 347 stroker

 

I say toss on the 36#ers and call it a day. Just as easy to tune and it gives you a little room up top in case you wanted to make a few changes down the road, or even add a dry kit.

But then again, 30#ers should hold up pretty well too, especially being N/A.

I guess I would choose whatever I could get at a better price (or whatever I already had on hand.) That's how I ended up with my 30# injectors. Guy at the shop upgraded to 42# for his supercharged 347. So I got them for $100. very few miles on them and they flowed great.

 

thasts what I was leaning towards sam.. a 75 dry shot for a little off-the-line.. oomph

 

Well, I just picked up a Pro M meter and 24lb injectors, then I decided to go build a turbo set up and was wondering if I should sell the 24lb stuff and go bigger. I wish I would have decided a week earlier.....

 

I think I am going to go with 30# in my 331. But I guess we will see how much my plans change by next season.
