i was wanting reccomendations for injectors for my motor in my sig.
i was thinking red tops is this a good choice?

 

What is your displacement? Are you spraying or boosting? If you are stock 350 disp, or even 383 then the SVO 30#'s (red tops) will be just fine, but if you are spraying or boosting you might wanna step up to the 42#'s (green tops) and upgrade your fuel pump. All depends upon your plans.

 

To get in the ball park, multiply the expected flywheel HP by 0.07

Example:

500 flywheel HP x 0.07 = 35 #/HR.

That assumes you have an "average" tune that will give you 0.476 #/HR/HP brake specific fuel consumption, and don't want the injector duty cycle to exceed 85%.

 

^That's why you keep him around Excellent advise as usual!
