Will LS1 injectors supply me with enough fuel for a 125 wet shot? I'll be getting a racetronix fuel pump as well.

 

Depends on which LS1 injector you are refering to.
There are three part #'s that come to mind.

 

agreed, on the 3 sizes.

But question? Why do you need larger injectors based on your sig, and a wet shot?

Ryan.

 

I want adequate fuel and ignition for this nitrous setup I'll be doing this winter. LS1 injectors are bigger than LT1 injectors.

I'm going to use nitrous to get a mid to low 12

 

you can keep the stock injectors and have plenty of fuel for a 125 wet shot. if you were planning a dry kit,then you might want to look into different injectors.

i have stock lt1 injectors and run a 175 shot to 11.0's with a stock longblock LT1.my car runs 12.36@109 without the bottle,so the stock injectors are fine with a good fuel pump.

the WET kit supplies it's own additional fuel,so you only have to worry about feeding n/a hp with the injectors and the nitrous will be bringing along it's own fuel enrichment.

 

LS1 injectors are 24lb and 28lb... pretty much the same as LT1 & LT4 injectors in delivery. Construction is totally different.

 

And aren't the LS1 injectors rated and operated at 4bar (58psi)?

Meaning they will flow 15% less than rated in a 43.5psi LT1 fuel system.

 

Yes, LS1 injectors are rated at 58 PSI. Year 99-00 26.4 injectors will actually flow less than stockers on our pressure and Year 97, 98, 01, 02 and 03 28.8s will flow just the same....
