Hey guys, any input would be greatly appreciated.

I've got a 92' F-150 4x4 with a 302 and a 5spd tranny(pics in gallery). The motor has been rebuilt with a .030 overbore. I put a superchip and a K&N element in as well as take the "fresh to airbox" tube off for less restriction.
I'm running 4:19 gears to compensate for the 6" lift and 33" meats.


That being said... what in the world could I bolt up for some noticeable ponies that won't burn a hole in my wallet like a supercharger(Kenne Bell-$3500).I was thinking like a bigger throttle-body,heavier injectors,or an igniton system like Jacobs or MSD.

Any help would be great thanks!!

 

The words "bolt-on" and "noticable ponies" shouldn't really be put in the same sentence. Since you've already bored-over and chipped your engine, and installed different gears, I don't think you're gonna be satisfied with any evening wrenching project. You should check out fordfuelinjection.com, under their EFI Performance heading to see what they have to say on the subject...

Having said that, I don't usually follow my own advise. Since I'm not really comfortable in tearing into the guts of the engine, I've mainly done bolt-ons to my truck. I've thrown in a K&N open element filter, a MSD ignition system, and have a set of underdrive pulleys in my basement waiting for a snow-free weekend. You could bolt up any of these and expect to see some SMALL gains in HP. For my next mod, I'm looking at replacing the stock fan with an electric one (I'm going the junkyard route, but there are several aftermarket setups specifically for our trucks). Basically, what i'm saying is small monetary input=small HP gains (which really sucks ). Maybe someone else out there could give you some better ideas...

 

I thought about the ignition but dont know exactly what it does or what brand to go with. I am not very familiar with the underdrive pulleys what exactly do they do? Also would taking the airbox out of the equation and adding the conical K&N help or is that what you have?

Thanks for the help aikigod!

P.S. 4:19 in the first post was a typo...lol I meant 4:10

 

"bolt-on and noticable gains" = blower, turbo and/or N2O.

An MSD Blaster coil will increase the spark voltage, but I wouldn't do anything else to the stock ignition unless you go with boost or spray. Any one of those three will give you the most HP increase over any other single bolt-on component.

 

Blurry: Haha, alright you got me, but he was talking about inexpensive bolt-ons (... won't burn a hole in my wallet like a supercharger(Kenne Bell-$3500)).

SkorpioN: I'm using the MSD 6a unit with a TFI blaster coil. I researched ignition systems extensively on this site and most people rated their MSD products favourably, more so than Jacobs or Mallory. Ignition kits like these create either multiple sparks or longer/hotter sparks to burn your fuel more completely.
As for underdrive pulleys, basically they replace your stock pulleys (crank, water pump, and alt.) with different diameter ones, which then turns your motor accessories (a/c, power steering, water pump, air pump) at a slower rate, thereby reducing drag on your engine and magically freeing up horsepower (or so the companies claim...). Some people experience too much of a loss of charge from their alternator during idle, so I'll be definitely keeping an eye on my volt gauge, but I figure since I don't have a thumpin' sound system, I should be OK...
Finally, open air filters are kinda hit & miss. On one hand, they suck in a lot more air than the standard boxes, allowing the engine to breathe easier (definite plus). But on the negative side, all the air getting sucked in from stationary/low speeds is hot air from the engine compartment. Personally, I like my setup (see my gallery), I've only felt it stumble 2 or 3 times, while I was stuck in traffic on the hottest summer day. The "seat of the pants" meter and the deeper, throatier sound coming from my engine bay more than makes this a worthwile mod in my view.

 

You might find removing the airbox or even the fresh air hose actually restrict power gains, even with the K&N filter in place. Bigger injectors and bigger fuel pump to match(with proper regulator) will make a seat of the pants difference. I'd add the aftermarket ignition at this point. MSD, Jacobs, and others make decent parts here. I like the Jacob's for it's true bolt on flavor, and if it fails, your OEM ignition is still there, and can be plugged back in for back-up to get you home in minutes. Under-drive pulleys are smaller diameter pulleys that reduce the amount of hp lost to turning such devices as A/C, alternator, water pump, and power steering pump. If you're going to an electric fan, you could also go to an electric water pump, and then reconfigure your belt system to meet the needs(might be tough with the serpentine belt, was easier with v-belt systems) Under-drive pulleys don't work as well at lower speeds. Especially in regards to the alternator and charging.

 

Ooops, I guess i missed that one.

I'm running my stock ignition system and a MSD Blaster coil on my 94 Lightning w a Vortech supercharger and a host of other modifications. I see upwards of 14 psi and I also run spark plugs that are one heat range colder than stock and I have never had a problem with the stock ignition failing. I ran a BBK system (made by Mallory) for a while before I installed the blower and I wasn't that impressed for what it $$$.

I agree on using underdrive pulleys, I noticed a difference on both of my trucks with them. I have also noticed gains with, e-fans, and a set of headers and better flowing exhaust.
