OK...I have a 2002 F150 larit w/5.4L. I have a sweet cat back "True duels", Superchips tuner, K&N FIPK air intake w/air dam.... What should I do next? The MAF will work up to 400hp. So im told. Im ok with that? E-Fan and TB are my next two thoughts. Anyone have one or both of them and what did you think. Is there anything else I should do instead?

O...and anyone know what HP I might have at this point?

efans yes... spacer... no its a paper weight u wont feel anything and it does nothing for u. it makes a whistle. give me 45 bucks ill whistle in ur truck all day for u. invest the spacer money in to underdrive pullies.

 

oh wait i dont kno if u meant the spacer or just a differant tb, if anything i would find a used tb and try removing some of it urself with a dremel or something. there was a post once how to port it out. if u can find a used one from a junk yard and pay 20 bucks or something i would try that before dishing out the big bucks, if it works it works if not hey it was 20 bux and u learned what not to do.

 

ya...ok..ill try that..the underdrive pully. What does it do? how much HP? spacer..na im not thats dumb...lol

 

Efans will be your most noticeable next mod. Adding the TB, you aren't going to notice any difference. The larger TB is realistically only going to help forced induction applications.

 

ok...E-Fan it is. I know troyer sells a kit. it that any good? or is there a better one? and still thinking about the under drive pully?

 

underdrive pullies just put less parasetic load on the engine so the crank doesnt have to turn as much assecories, frees up horse power u already have. i would do a serch there are quite a few people with them. also try looking at troyer performace's web site. they got them for sale.

 

how do i know if i have 6 rib or 8 rib belt? Is the pully a good thing? anyone have one?

 

Just take a look at your pulleys and you will see a series of thin ribs on the pulleys where the belt lay in. It will either have 6 spaces or 8. If I remember correctly the 2002 has 8, but I would double check.

 

I have not personally used the Troyer kit, I have read some complaints about the mounting method though. I went with the Flex-a-lite setup for the ford application. It mounts directly in the stock location, has two fans, and pulls up to 5000cfm. It is expensive, at $399 + shipping from summitracing.com but I found it to be well worth it.

I am not a fan of underdrive pullies though. I used them years ago on my mustang and I had charging and cooling issues. I ended up removing the alternator and waterpump pullies and just using the crank underdrive in order to get the system to still maintain a charge and cooling capacity. But I have heard some people who love thier pullies from troyer.

 

the fan will not hurt anything..commen since. thats next for sure!!!!Will or can the pulleys do any damage?

 

I have troyer pullies and love them...

 

did you feel them? Hard to install?

 

Maybe an hour or so to install... Yes, they made a slight difference.

 

The down side to the two pulley kits like Troyer's is that the alternator is underdring 20%. So, if like me you have a 95 amp alternator you could be losing up to 19 amps. I ran the pulleys with the Troyer efans for a few months, with no problems though.
