Thats Strange, thats exactly what I wanted to know.

Strange which way would you go? A KB or a custom ATI P-1SC w/ PDS intercooler running 9psi? The KB seems like it would be good all the time, even if I just want to pass and have the extra power, and the off the line power. The ATI while it would be faster in the 1/4, would be not as useful when towing or jus teveryday driving. I might go ahead and get a KB. Where can I get on at a decent price?

 

i know superchargersonline.com have them for a decent price.

 

Yeah I have been looking there. They have them for $3399. I dont know how to tell if its the 1.5L or 2.2L version.

 

Personally, if I were going to put a blower on a truck, my choices would be, in order:

1) turbocharged w/ intercooler
2) turbocharged w/o intercooler
3) Lysholm
4) Roots
5) Centrifugal w/ intercooler
6) Centrifugal w/o intercooler.

I'd prefer the turbos because, if properly sized, they'll spool up much faster than a belt-driven centrifugal, can make boost at moderate revs but unlike a positive displacement blower only make boost on demand, not all the time. They're generally a whole lot easier and cheaper to install. The error that most people make with a turbo is sizing them too large in order to get max. boost at max. revs and ending up with a system that is useless in everyday use.

Whatever unit you decide on, make sure that it is a complete kit, including fuel augmentation and ignition retard as well as the blower and the mounting hardware. Call the manufacturer and talk to their tech people, find out what they recommend.

 

Which turbo systme do you recommend? I saw a kit for the 5.0 stangs, that could be used on the trucks, but the company went out of business, and the price was expensive like over 4k

From what I also understand, the KB doesnt make boost all the time, once you goto 3/4 to WOT, it boosts, and you cant control the boost level. Its all or nothing. So once it starts boosting, you have all 6psi.

 

Beastie,

The KB truck kit has no bypass installed, so in effect it is making boost all the time.

It would be fairly easy to use the Mustang type setup with the bypass if you went to a Mustang TB and EGR.

The part you are reading concerning boost is somewhat misleading. Even with a bypass the KB will produce its boost at lower revs, so once you get into the gas pedal the boost is available. Centrifugals work much closer to turbos in action in that it takes revs to build boost. So if you nail the gas in third and revs are at 2500 the KB is at whatever boost you have it pulleyed for. Do the same on a centrifugal and you are below the boost curve waiting for it to build.

My truck also has 3.31s. You know how there is that agonizing speed at which you don't downshift, but you are at the low end of the torque curve? The KB would fill those areas better than the centrifugals would IMO.

Do some searching over at the Mustang sites. Corral.com(net?) has some great blower forums. Even many of the Mustang owners with 5 speeds prefer the KB for the brute low end torque. Considering they have much lighter vehicles and 5 speeds.....

 

I know what your talking about. If my truck doesnt downshift at 35, it is a dog till about 45-50, where it starts to pull again. It will usually downshift at 35, but if im going 37 it wont, and it is slow.

I kind of like the idea of stomping on the gas from a dead stop, and just smoking the *tire.* Thats what I love about our 71' 442, all that torque is just increadible, well it has an abundance, its rated stock at 505. The truck would have to have alot more than a blower to get those #'s.

 

here ya go, this is what a KB looks like on a 427 (this is going into a Gen1 lightning )...

I have a 14-71 with a BBF intake that someone with serious asperations can install on their truck. I also have a Nitro Barndoor injector hat to add on to it. Should be good for one trip down the block before you spit all of the rods out of the block.

On a serious note, I have a friend that rebuilds the small GM blowers found on Grandnationals. They can be adapted to most anything. I think he was getting around 400 bucks for them rebuilt.
A 4-71 or a 6-71 shaved on a V8 will also make serious power and can be tuned with pulleys for over or under drive.

http://www.blowerdriveservices.com and http://www.superchargerusa.com are very good sources for roots and screw type blowers.

I looked into a Kenne Bell for my 93 5.8
It would get me to 290 HP

New 2004 s with 5.4 3V will have 305
Decided to wait and get the 2004 5.4 3V or the Dodge with a 5.7 hemi 345hp

After 10 years I deserve a new truck

 

Justin93F150,
According to KB, your truck would have 303 hp.

Donate I saw that engine like 2 nights ago, that thing is sweet. All that and no long tube headers??

So I get A grandnational blower, where do I get the exhaust manifold to work with it? and the first link doesnt work.

 

Beastie,
I fat fingered the address, it is

http://www.blowerdriveservice.com


My Funny Car engine has 2200 HP with a blower.. Costs a little more than most 427's..

As for an exhaust manifold, it is not an exhaust mounted unit in any way shape or form, it attaches to an intake manifold and that can be made or purchased. Most folks use large tube headers in addition.

I have never used one, but he sells a ton of them to Mustang owners.

OK, now I'm confused. The Grand Nationals used a turbo, not a blower. At first I thought you just used the wrong wording. Now it sounds like a blower, but that isn't a normal GN thing, so it couldn't be rebuilt from a GN...... unless it was an aftermarket blower to begin with.

 

No offense intended towards anyone, I swear, but this thread highly resembles a kid running through a candy store with his parents and siblings in tow, trying to guide him, but without much luck.

You have several issues you need to deal with, including the fact that you're gears are going to have to change. If Dad says no to the gears, forget a blower. That's like "Dad says no Bic lighter, but I'll talk him into a flamethrower". Not to mention your gears would be counter productive to a forced induction engine in a 5000 pound truck.

You are going in too many different directions here. Do some real research. Learn what a blower does, and what a turbo does. Don't say you heard one is better because it's available. You sounded well informed on this subject early on, but the more I read, the less you seem to know. I'm not trying to be a jerk, i just think that you would be wise to do some real research, with multiple sources.

I dunno. I'm sorry, this thread just made me so dizzy that I was starting to question the simplest of truths. I don't usually post like this. I must be under a lot of stress elsewhere. Just forget I said anything.

Good luck.

 

PKRWUD, you have actually hit the nail on the head. I have become so confused with this thread since it started. It has gone from blower to blower, to turbo now. I have really lost my mind. I think for now, I will just stick with the simple bolt ons that I priginally wanted, then later on, change the gears and get a KB blower. I think I will do underdrive pulleys and electric fans, any other suggestions?? and PKRWUD, how many amps is the alternator in my truck, 95 or 135? Thanks for the help.
