i have a 99 ford f150 with a 5speed and a 4.6 and i want to break 14s all motor. i plan on spraying eventually but not until i break 14s. i plan on putting most bolt ons and getting an excalibur2 tune and maybe heads and a cam. just not to sure and need some advice. thanks

 

You need two things:

1) Ad in Auto Trader reading, "For Sale, F-150, 4.6 5-speed."
2) Ad in Auto Trader reading, "Wanted to Buy: 2nd generation F-150 Lightning"

Seriously though, you'll be hard-pressed to build a naturally aspirated truck with a 4.6 and a manual and get her into the 14s without some serious work. Neal the HP Freak and JMC are your two best resources for that info. All I can tell you is that by the time the engine is strong enough to get you there that fast, the tranny won't be.

I was trying to figure out if he meant break loose 14" wheels or break 14 seconds. From the factory it should break 14 seconds in the 1/8th mile.

LOL...you probably mean 1/4 huh?

Remeber that darwin award for that guy who strapped rockets to his car??

It can be done....is it cost effective??
Is wet nitrous all motor? It would help. It might even get you there.
Does all motor mean no additives like Nitrous Ox. or Blower?
If you snag a bigger cam, install larger valves, replace pistons with something a little higher compression, toss the old ECM and injector set up and go aftermarket, yes, it will go faster than 14 on all motor. Oh, yeah, might want to change gears too.
The cheapest solution might be a little blue bottle.

 

In my book, Nitrous and/or a blower aren't all motor. Forced induction is (IMHO at least) the most reliable, least destructive method, and can be done with bolt-ons and a good tuner on the dyno. I'm not a fan of nitrous as the engine is treading a fine line between OK and self-destruct.... a half second of lean fuel is enough to toast it when you're sprayin' whereas a 1/2 second of lean just results in power loss with a S/C.

Just my opinion though....

-Joe

 

I will testify on the self destruct part, but boy, what a kick in the rear. Sure wish I still had that 351 Clev with the quench chamber heads. Was a great engine till I got crazier and crazier with the nitrous. Unless you have lots of money to spend and lots of time, don't play with nitrous.

 

with where i am now all i would need is long tubes and a good tune and i would break high 14's. the 4.6L is faster no matter what if u look all the speed records are set with the 4.6L not the 5.4L. yes the 4.6l has less power but it reachest its power quicker due to it being a short stroke motor. thus makin the engine faster. but intake Dual exhaust a good tune a MAF porter intake plenum 75mm throttle body and long tubes u should break into the 14's 4.10's would help alot as well

 

How is your truck setup? Is it reg cab or extended cab at all? Extended cab adds around 625lbs over a reg cab truck on the 97-03 body style.

14's in a reg cab w/ maual tranny shouldn't be hard with bolt on and will be easily possible if you get headwork and cams. If you're looking into getting that serious, then see about getting the PI heads too. You mightr run into tranny problems eventually too. But, auto tranny loses 65hp down the drivetrain while manual loses only 35hp.

Also, you should have one of the trucks that don't have a plastic intake manifold. I've heard from Mike T you can get a good boost in power by porting that intake manifold out because there is a hook in there from manufacturing that really hinders the air flow. I was close to getting to that point on my 00' truck but it got totaled before I could go nuts w/ my old 4.6l engine :-(

check out sean hyland motorsports for inspiration on the 4.6l motor. Also, get his book too on the 4.6l engine. It's an intersting read if you like the 4.6l engine and will give you some good info.

 

Out of curiosity....what "speed" records as it applies to the truck variant? "Yes the 4.6 has less power but reaches is Power quicker" Benificial for the first 50-75ft maybe but not in the 1/4 mile where the 4.6 runs out of breath.


Peak HP comes 250 rpm's sooner and is 69 hp less than the 5.4. Peak torque also comes in quicker by only 250 rpm's and peaks at 72 ft/lbs less than the 5.4...this does not translate into better performance for the 4.6 unless the vehicle with the 5.4 is a crew-cab 4X4 and the 4.6 is a regular cab 4X2.

 

my truck is a regular cab and it runs 16.6s bone stock. in the next few weeks i plan on a limited slip, headers, exhaust, and intake. i hope to be in the fifteens

 

u should have stock LSD differential. u can find some long tubes on ebay for ur F150 for about 298.00 last i saw em. if not jet hot sells them for 280. and dont forget a set of under drive pulleys and E-fans wake the F150's up alot

 

You getting a tune done and chip for the headers? I believe you need it.

 

HI!... F-150's don't come STOCK with posi. You have to order it. 98% of F-150's on the dealer lots DO NOT have limited slip.

 

yea i plan on a tune just got to wait on the funds. takes litttle longer to save up. just wandering what would be the best direction to go with e-fans?

 

You don't necessarily have to order it separately..... some of the packages include it as standard IIRC. I want to say that the off road/FX4 packages included it....

-Joe

 

I know alot of the earlier off-road packages did not make it a standard option.

Quite a few of the ORP trucks I have seen are open differential.
The FX4s might give you LS though, but I dont remember seeing that as one of the parts of the package.
