4th injector question

[Vilas]

i don't have a turbo but I read all the posts about them and darn it if I can't figure out what you all mean by a "4th injector". Wouldn't a 3 cylinder motor have 3 injectors? I'm clearly not understanding something and any help would be appreciated. Thanks!

The Turbo guys are running out of fuel with stock setup and bigger power. They add a 4th injector to give additional fuel. Basicly like a Primer for topend. They put that injector in the intake or intercooler.

So they add fuel to the air intake? Do they just cut a hole and mount the injector there? I'd love to see a picture if anyone has one. Thanks!

Read Mrsled's thread in the stickies on going to 12psi. There's pics in there of the 4th injector install

Here's a picture of one mounted in an innercooler, from mpi's website.

The mcx kit has 3 extra injectors one per cylinder but that's 270hp
