So I read on yoursciontc.com about doc i's GFI Stage 3. Ive searched on here, SL, and there about GFI and Ive come up with nothing! I feel so stupid for not being able to use the search function correctly.

Heres the link to doc i's thread http://www.yoursciontc.com/forums/in...showtopic=7096

WHAT does G.F.I stand for?!

I understand the heat-soaking theory and makes a lot of sense. My question for you guys are...

*Answered 1. What is the meaning of GFI. ( GFI = GHETTO FAB INTAKE. LOL. )
2. Does it yield noticeable gains?
3.What is stage 1? (what do i need to do and what materials will I need?)
4. How do I get to stage 2
5. How do I get to stage 3



Sorry if its been answered many times before, but I'm just getting so anxious about this mod that I just have to know!

If anyone can help me out, it would be great!

 

2. not really

3-5. it says right in the link you posted...

 

UGH! I read all 22 pages twice only to find this on page 2 on the thrrd time around:

Summary:
Stage 1- Correction, look above.
Stage 2- Remove air resonator.
Stage 3- Remove intake piping from air intake box to throttle body.


In stage 1, what angle did he use as the bent-pipe from the box to the flex tubing?

And in stage 2, what exactly is the air resonator?

 

Is there a Doctor in the house?!

The air resonator is the big weird box thing in the middle of the intake tubing. The box itself is connected by a clamp and doesn't appear to do anything except baffle the air.

As far as gains go, Doc measured a considerable difference in IAT. Whether that translates into real power is really questionable.
