I just get crazy ideas in my head and was curious as to how hard it would be to put a lightning supercharger on the lincoln navigator's 5.4??

I'm assuming that the internals aren't forged on the navigator's 5.4, how much power is the block good for? (I did a search about the internals, and coulnd't find anything, but I'm sure its been discussed, so, sorry guys.)

Is there anyway to disengage the AWD on the navigator? whats the top speed with AWD engaged?

What transmisisons are in 99-01 navigators?

Thanks,
Matt

 

TTT please.

 

know of anywhere I could find out? I've been looking and havn't found answers yet.

 

It depends on your motor. If you have the 4v Intech the Lightning SC won't bolt up. I've got the Intech with a Kenne Bell SC. I popped a rod when trying to run over 14psi on the stock rods. IMO the weak point in the motor.

I'll give you my opinion that you can do about 500-525 motor HP on the stock internals. Others may disagree.

 

If you have the regular Triton 2 valve, the supercharger is something you can "relatively" bolt on. Of course by that I mean swapping: intake mani, various brackets, injectors, intake sys, engine management, and other small but important stuff im forgetting. If you can get a complete takeoff, then it can be done. i have been researching this idea for a while, and it can get expensive VERY fast! Now say if you were to find a totaled Lightning, then the process would be alot easier, no need to hunt down small parts when peicing the swap together.

 

ooohh, so the block is stonger than rods and pistons, so i guess they are not forged.

What is different about the lincoln's 4v intech that won't allow the lightening blower to bolt up to it?


thank you.

 

The lincoln is a 5.4 4V (four valves per cylinder and two camshafts in each head) the Lightning is a 5.4 2V (2 valves per cylinder and one camshaft in each head) The intake ports won't line up for the intake manifold.

 

i thought the lightings had the 4v...hmm.

so you couldn't put a lightning blower on a 4v 5.4 but you could on a 2v 5.4 like the ones in expeditions and newer f150's?

 

^ That is correct. In fact it's better to SC the 2v motor over the 4v. The primary reason being the 2v has a lower static compression ratio. With mine at 9.5:1 (I think) I've had to fight detonation issues at high RMP/High pressure operation.

Make no mistake, mine makes a lot of power at 6,000 RPM but I always feel like I was running on the edge. I don't believe I was experiencing detonation when the rod broke; it's just that the stock rods are so long, brittle, and thin. (I think they are called cryo rods because they are cold treated and then cracked at the main as opposed to being cut, machined, and honed.

The pistons these motors have stock are hypereutectic. I guess their best quality is dimensional stability. They are allegedly weaker than forged but I haven't had problems with them, only the rods.

I know I'm going to break this bitch too, it's just a matter of time, but it seems I can use a long block version of the GT 40 as a replacement, which will be my next move. I only seek 10 or less lbs per horsepower, but that's quite a challenge with this much mass. I really should just keep the truck as a truck and buy a Mustang instead. (If it weren't for that little perverse pleasure of outgunning a basic GT Mustang ins straight-line acceleration.)

 

okay, so on the triton sohc 5.4 we're still saying 525 and thats only becuase of rods? block can hadle more? I did find out that the crankshafts were forged in the intechs, are they forged in the tritons?

what transmisisons are in the f150's and how much power are they good for?

How much does a 4x4 f150 weigh?
