Does anyone have expereince with adding a fifth (or more) injector? I am just wondering if it is worth it.

Thanks

 

What are you trying to accomplish with it? More boost? Better AFRs?

 

Both I guess.

 

Several people around here are running additional injectors. IMO the best way is to add 4 injectors fed off a 2nd fuel rail (one additional injector in each intake mani runner).

The FFS supercharger system uses a 5th injector, no intercooler, and an otherwise stock fuel system, and is good for 190-210 whp.

Other than initial installation and tuning challanges, there are tons of upsides.

 

Thanks. I have the Power link 2000 that is actually a useful device to control the additional injector/s. anyone used it or heard about it?

 

Power link 2000?
With controller, or USB?

Has it map sensor and rpm?

I had an injector driver like this and I was going with 5th injector. I had no problem, and then I used 6th injector (2x550) and walbro fuel pump. I worked GT28R 15-16 psi at stock pistons (8,5/1 CR) and timing retard at 7 static with no problems!
