E-fans and CAI 5.4 2v

Your assessment is likely accurate; hence, the “custom” fans. The aluminum shrouds provided with the fans were spot on, but that’s where the custom stopped. The OD of the fans would have made cutting necessary, regardless of clocking them. But great thought!

Excellent install work ! Hope you see some gains from the project. Looks like a pilot did it !

Hey I did spend my first 8 years in the Army enlisted as Blackhawk mechanic / crew chief, and been turning wrenches since before you were with the bigs I still need to take all that time and sit down with the FSDO to get my A&P! It’ll cut down my costs owning the 310

Really nice job. It sure does open up the front of the engine nicely. The stock fan and shroud are often in the way.

The amount of workable space you gained cannot be understated. Oil filter change should be super easy now. I feel like the stock shroud always gets in the way. I think it’s a shame though that FF didn’t make the kit more bolt on ready. And to make each fan separate? It’s good that you got it to fit and have already noticed some driving improvements. But it makes me wonder if the work required makes the choice worth it, if you don’t have the time and budget to do more work beyond install and connect. Looking forward to more info on the gains you get though with no parasitic drag on the engine. You already saw really good gains with the intake and exhaust.

Quick update on MPG increase after the intake and e-fan install. Bad news: I haven’t seen a discernible increase in MPG so far, because - Good news: I can’t keep my foot out of it.

The throttle response is significantly better, the 5.4 spools up quicker, and couple that with the throaty exhaust, it’s just a blast to drive. Again, I know it’s not a sports car, but most definitely a sure-footed platform that instills confidence on the road and a really great performing truck now.

A little modification required to make the e-fans work, but absolutely worth the upgrade if anyone’s contemplating it.

I am sitting here just laughing and thinking hell yeah. The smiles per gallon is so much more satisfying. My wife said the same exact thing after we put exhaust and suspension parts on her Monte Carlo.

I keep thinking about the e-fans due to the space it frees up. Despite the fact that I don't think it would be as reliable long term.

The first e-fan installation was in 2000 with a Flex-a-Lite kit. At that time the fan controller was integral to the fan assembly. In ‘05 that fan controller failed. The only way to replace the controller was to replace the entire fan assembly. I ended up selling that truck and the next guy dealt with it (of course I disclosed the fault).

My next install was in 2011. With that kit, the fan controller was a separate assembly from the fans and shroud. In speaking with Flex-a-Lite, they designed that deliberately so in the event the controller failed, it can simply be replaced without having to replace the entire fan assembly. That fan controller and electric fan kit are still going strong 13 years later in my old supercharged 5.4 3v.

I’ve got faith in the Flex-a-Lite fan controller and confidence in the fans themselves based upon the FF dynamics reviews over the past two decades. I think you could be confident and installing the same! Go for it - it’s only money

That does make a good case for reliability. It is something to seriously consider once I have my vibrations resolved, rusted rocker and 2 smaller rust issues resolved.
