could we get back on topic now? how about flaming or wutever your doing in some other forum, i even thought up a title for you to save some time. "The supercharger post that ended badly and wasted Chris's time"

ive been thinking on turbos here recently. someone said turbos are good for power, but not torque. here's my argument on why i may approve a turbo setup:
-arent turbos connected to the exhaust manifold? anything restricting exhaust flow produces backpressure right? and more backpressure to a certain extent produces more torque, correct me if im wrong. (i did feel less in the low end when my cats were taken off, meaning...there was less torque)
-so wouldnt a turbo be a good booster of torque and that may be why they work best on 4-bangers because they have less low-end torque.

anybody want to sway me on doing a large turbo, intercooled setup?

 

Yes sir, right away sir..

 

you dont want a big turbo, unless you want to use nitrous to just get the turbo spinning.lol you will have tons of lag with a big turbo and even less low end. i would sugest a smaller turbo so you have boost in the lower rpm guage. im really confused on what you are trying to do, last month is was SAS and big tires now you want a big turbo?? why.. a big turbo will only help if you are at high rpm all the time, and if you get SAS you would be planing on offroading which when offroading you will never or hardly ever hit high rpms. i dont know im just lost...

to do a turbo setup right i think you would have over 4grand and maybe still not tunned right, and for what you want sounds like your best bet is to buy a kit.

 

ok D what eaxctly have you done to your motor? as i dont have any idea all i hear is your fast! well i want you tell us what you have done. and i personaly think the race or shut up is a good point, execpt in your case if u miss shift ur $h1T outa luck. me however i am in an auto one advantage to an auto hehehe.

 

what ive heard, is it is now a 4.x not a 4.0... but not sure???? and i dont think he wants to share. i dont want to give more info as its not mine.

 

..I'll say this much. I'm a relative bafoon about this stuff and can barely tell a supercharger from a turbocharger. He's supposedly got the same engine as I do (4.0L SOHC V6).. But his engine compartment sure don't look like mine!

 

I have to disagree to some extent on this. you can do a turbo setup pretty cheaply these days. You can buy turbo's out of junkyards for around 50 bucks a pop. And those are the ones with external wastegate and no shaftplay. For a re-build turbo you're lookin at about 35 dollars.

Now comes your exhaust. Since it's gonna be custom due to no companies making downpipes for our trucks, you can get someone to make one for about 200 dollars. give or take 50...

Now you need to drop compression down to around 8.5 - 8.25 : 1 to keep from blowin your motor. you're lookin at about 700 dollars here, give or take 100.

Here's your money spending now. You'll need a programmer to remove factory programming, like the SCT Tuner. 325 dollars. I suggest the Greddy EM/FM system piggyback which i believe is around 1100 for the customized system. but it is tailored to your specific needs.

Add another 300 for a decent intercooler and some tubing to complete the system...oh yeah, and another 150 for gauges...

that should have about everything you need..minus a few odds and ends...

with a Garrett T3/T4 hybrid or T025 you can probably expect an increase of around 7-8%...keep in mind that is just a rough guess on horsepower...i'd be afraid to try and guess on Torque....due to rearend differences in different trucks...

 

um lets see your at like 2500 and you half assed it with used turbos retro fitted on, if i was wanting to do it i wouldnt get my turbos from a junk yard. if your gonna do it i would go all out, if you do it half *** you wil wish you did it better later. do it right the first time or dont do it at all.

 

easiest ways to distinguish between super/turbochargers...

Turbos:
Round in shape, 2 sections (compresser/expansion), usually located near exhaust manifold

Superchargers:
Located on top of intake manifold, 2 sections (head, body) has pulley with belt running down to crank usually ( i have seen a few variations on the belt drive though)

 

I put a Garrett T3 on my cavalier that came from a early 90's model talon. it ran like a raped ape until i sold the car...never had any issues with it...turbos are not hard to rebuild even if you do have one with shaft play...and they are very customizable....

Good example:
2.3's
turbo swap from t-bird SC...you can put a garrett T4 on the flanges with the use of a 14 dollar adaptor from turbonetics and pick up 3.2 to 3.4 lbs of boost...and the motors can handle it

 

New isn't always the way to go when you're going extreme

 

Then why does my supercharger on my F150 look like a turbo charger sitting in my engine bay but driven by a pully? hmmm

If you dont believe me here's my kit....

 

then you don't have a supercharger you have a hybrid

 

Prolly looks alot like this

powerdyne also makes one like this as well

 

lol no.. i have a Vortec Supercharger. It is not a hybrid as shown here

lookie for urself http://www.truckperformance.com/prod...ductID=1223290 aint no hybrid action there.. 100% supercharger just not a roots based charger. there is more than one kind

 

Was that directed twards me? If so my comments were somewhat sarcastic. My point is that I couldn't tell exactly WHAT was done to D's truck, just that QUITE a bit was..

 

Oh....i think my initial post may have been...but not just for your benefit...for everyone's...even my own....it causes me to look into clouded memory and bring old stuff back to the front and it makes me wanna learn more and do the research....

 

ok, that's some of the old school in me...i grew up racing with guys who used roots based, and back then there were types other than roots based, so when they came out they adopted the hybrid title from some of the older guys....i'm not saying you don't have a true supercharger. If it takes intake air in, compresses it, and pushes a larger volume into the engine it could rightly be considered a supercharger, well with a few other small characteristics as well though...
Not tryin to take away from what you have, you just clarifying on different types. just like you clarified what I was calling a hybrid charger....
I think what you have is called a "Screw type" I'm not 100% on that though, so if i'm wrong correct me.

 

are all centripetal superchargers(supercharger that looks like a turbo, is mounted on the front of the motor and run with a pulley/belt) universal or could they be made to fit with a bit of modification? does anybody know wut im talking about? that may be the best way to go for me.

can doug at bamachips write a program for superchargers or do they have one?

 

you are correct.. centrifugal is correct.. I see what you are saying now.. I was always used to roots based growing up and then i found this centrifugal and needed it.. not many people run them yet
