What do you mean it doesn't agree with the efans? I was under the assumption that KB made 2 kits, 1 for the clutch fan and 1 for efans?

 

It fit decent with the ls1 fans, but the vertical charge piping right before the T/B always hit the shroud around the fans. It did it worse with the 05+ fans. Silver-mod-o ran into the same thing. I could make it work, but the straight silicone coupler on that vertical section was almost bent 45* and the BOV was pushed into the fan shroud pretty hard.

I'm not knocking his kit in the slightest. Its still the best kit IMO, the heavy-wall manifold is worth its weight in gold alone...

I don't know if I'm explaining that good enough, I didn't take pictures. BUT like I said earlier, Kyle builds the kits for 4x4 and 2 bar. I am neither. I was kinda taking it out of its element.

I think if I were to do it again, I would just get the one made for the stock mechanical fan shroud. That way, that section of pipe would fit regardless.

 

My kit would only fit with my LS1 fans... I bought a brand new set of 05 truck fans and had to sell them because the up pipe into the TB was WAY in the way of the fan shroud. They are much deeper than the LS/LT fans...

 

That's what I remembered then. I was able to make that work, but everything was in a bind and I didn't feel comfortable with that.

 

I had A/W only when i had the compound turbo/supercharger setup on my truck. I didn't like it as much cuz the IAT's where always higher, cuz now you have 2 stages of cooling in your setup, using air to cool water then water to cool air. The only real advantage to it is being able to drain the water and put ICE water in it at the track.

From the feed back, I've gotten from guys like you, I'd think the best fix would be to keep the a/a and put a 4" 90* silicone off the TB pointing down and then the MAF, (now facing vertically) into it with the 3 3/4" coupler into the MAF. That should let you get away from the fans with the piping and pretty cheep to do.

 

Would you think there would be any benefit to decreasing the length of pipe if an A/W intercooler was used?

I might try that routing though. Right now, my setup is actually T/B, silicone coupler, MAF, silicone reducing 90. It was better, but not enough.

 

Honestly? I don't think you would notice any real difference other then about 8-10* higher IAT, in normal cruise. To me, it wouldn't be worth the money. Defiantly not gonna see a night and day difference IMO.

I had 2" of cold piping in my compound setup and it still took the turbo a second to actually spool, lol.

 

So it sounds like the mechanical fan turbo kit is the way to go, even though it is less aesthetically pleasing. KB, any plans to maybe redesign the piping to the tb to accomodTe 05 efans?

 

I think what i described above is about the best solution to keeping the MAF. No MAF and the pipe up the center seems to fit fine with 05 fans.

 

ah, no biggie then. I won't be running a maf anyways
