Re: My NF Fairlane is too slow
Welcome to the Forums!
There are several things which can wake up your NF:
1) Different heads. I think the Fairlanes have E7 heads? I'm arranging to buy some GT40-P heads which are off an AU (although there are other brands such as AFR and Trickflow, etc). If you do a search in the Windsor section here you'll be able to find plenty of info on all kinds of heads for the 5.0.
2) Different intake manifold. The HO manifold is a piece of asthmatic poo. Replace it! I've got a set of Explorer manifolds awaiting fitting... I'm going to get them done the same time as my heads.
3) Throttle body and MAF. Restrictive on a standard 5.0! Replace :p
4) Cam. There are many cams which go well with the 5.0, and I'm lead to believe that the standard one is OK if you stick with your standard gearing and don't go overboard with engine mods. I'm going to go for a Crane 2031 cam. I have know the theory behind lift, duration, etc, but not the numbers involved.
5) Diff gears. 3.27 are a tad slooooow off the mark, especially with the crazy 1st gear. Try 3.45, 3.7, 3.9 or 4.11 gears for a bit more get up 'n' go! Beware of anything above 3.7 though, I've heard that "torque reduction" comes in after then, thru the ECU or something like that. Then again you might not want to be cruising at 3000rpm down the highway with crazy diff gears, hahaha
I think the auto box can happily cope with 220kw, unless you mean 220rwkw!
The best thing to do is to look around the Forums (and this Windsor section in particular) to pick up all kinds of info & advice.
