What injectors for a mildly modded lt1 and 150-200 shot, cam heads, lt's?\


What are factory in these cars?

 

That's kind of a question with LOTS of important variables, but to give you an answer... the 30 LB SVO injectors are a common size and good choice for "most" of the modded LT1's out there..........this is what I'm using on my car with the mods in my car domain link.....they are PLENTY of injector for this application.......running a wet nitrous kit(like I am) doesn't really put any more duty on the fuel injectors, where as running a dry nitrous kit(like some do) that spikes the injectors for it's fuel enrichment, changes the engines injector needs pretty fast........ Basically, when a person has their "exact" engine/nitrous combination figured out, then an injector choice should be made.............Joe

 

Stock injectors are 24lb. for '94-'97, 22lbs for '93

These will work fine in a mildly modified LT-1 with spray. Unless the duty cycle of the injectors are close to being maxed out (not likely with minor mods).

Larger injectors will also require a PCM tune

 

I ran my stock injectors to 422rwhp and 566rwhp on a 150 hp wet shot....but every car will be different...I am also still on the stock opti

Like stated before the injector size will need to be sized for the motor needs...if you are running a wet kit ....on a dry shot the injectors will need to be sized for the total NA+nitrous HP needs

 

i click off low 11's and im on stock injectors running 82% duty cycle on a 300 shot.

 

Tell us what kind of car you have, and THEN we can tell you about the injectors.

Why not add a "signature", with basic info about your car.... year, engine, trans and any major mods. Helps you get meaningful answers.
