I'm building a 383, and looking out of my L98 for a 1990 vette.

I need to pick up some new injectors.

I'm looking for recommendations and trying to determine what lb. rating i need?

Compression 10.1
Heads = 113 heads ported
Cam = 224/232, 114LSA
Superram, AS&M runners, eddlebrock base, hedman elite headers, true dual exahaust, borla xr-1 mufflers.

My engine build thread is here.

Any recommendations for injectors?

 

30-36lb SVO injectors.

 

24's

 

Here is a link to the math... you can go to the bottom of the page and use their calculator. I recommend that you be honest with you hp calculations/estimations. I like to run the calculator a couple times using different BSFC to get a "reasonable" range.

With a 383 and a SuperRam I would go with 30lbs.

 

why 24?


all the calculators say between 30 and 36.



I found these two links

http://www.venom-performance.com/nf/...niInjector.cfm

24lb are good for 310 hp.

30lb are good for 385 hp

and here is another injector calculator(at the bottom of the link)

here is another thread asking the same question.

It would appear there are a lot of people using the 24lb injectors by SVO. But I'm scared of that minimal HP rating...........it would seem you would have to be exceeding the recommended 80% duty rating in order to make much HP.

I'm leaning towards 30lb or 32lb at this point.

 

I used that stupid math equation and i over fueled my engine.

 

give me some more info on your exp. It would help me in my build and purchases i'm making this week.

 

36-42, not sure why people are so scared to go with a bigger injector as long as you have a way of programing you own computer, hell there are V6 guys on here running 60Ibs with no problems.


How do you over fuel you engine
