Hello everyone...

I have a very clean 5.7L TPI 350, im runnin hypertech
ECU controls and headers .. thats about it
I managed to remove and (beat the **** out of) the
nasty Y-pipe thats been plagueing this car since the start.
The true duals help the car breathe a hell of a whole lot
more. A buddy turned me on to Forced Induction and he
tossed a couple of ideas into the air.

Paxton Superchargers. I saw how one
of those units just fits just right in the car without changin
visual appearance. However, I wanna set not 1 paxton but
(2) of them .. one on each side. A friend mentioned
fabricating a pipe in a W shape. So it takes the super-
charged air from both of the paxtons and sends it into the
Throttlebody in one 2 1/2-3in diameter pipe. Is this
overkill? .. or possible? I figure all that extra horse is gunna
require a new tranny, rear end and a burnt ECU chip .. should I settle for
1 paxton? what kinda advancements would I see with one Paxton?

I figure Forced Induction is the best way to go
If you wanna maintain exterior stock appreance.
Also, what kind of wear-and-tear would the TPI system take with a supercharger application??

Tell me what you guys think :hail:

 

I don't think Paxton even makes a supercharger kit anymore for are cars, I think you stuck with either a Vortec or a ATI Procharger kit. You probably wouldn't want a Paxton anyways, From what I hear they break down a lot.

 

Agreed, even if they did still sell paxton's, it would be a waste of money in comparison to the technology found in a unit from ATI. Self contained lubrication is what it's all about, and you can only find that on an ATI procharger. Installing two of them would cetainly inspire some head scratching when you open the hood (I have seen pics of this accomplished before on this board), but I doubt it would make for any type of power increase over what you could make with one of their larger units that was set up correctly. I think they make them up into the 1000+ hp range:

The vortech and ATI Procharger kits are easier to bolt on.

It would be a headache to get two paxtons on there let alone make them run without BREAKING. Paxton's have a history of being reliable. I broke three of them in one summer about 4 years ago.

 

I would NOT do it BUT Paxton used to make a bracket kit and siamesed discharge tubing to do just that.... Somewhere on this page there are a couple of pics of cars with them on it

 

Ok,

A larger one maybe a good choice .. and
you dont have to worry about settin two units
up with belts.

These questions pertain more to the ppl who run
or have run superchargers on a TPI system..

1) What kinda stress is put on the TPI
when having a supercharger application?

2) Does a superchager supply more torque?
or HP ... or both???

3) A small ATI self lubricated charger costs
how much more than Vortec or powerdyne ..etc.. etc..



Thanks for all the replies ..
I know imma bit of a stranger around here

 

"A friend mentioned
fabricating a pipe in a W shape. "


You see how that paxton has a U-pipe it looks like ..
Imagine drawing a line of sysmetry down the middle of the car and doing that on the
exact same side ...I thought it would look like a monster
and definatly would turn some heads thats for sure ...


alil off the topic of superchargers .. but more TPI

Where do I snag some Large tube runners for the TPI??
Not 4 runners on each side ... but two fat runners on
each side // are they better??

 

Here you go, I found this post and the attached photo with a simple 'twin blower' search. Most of the answers you seek could easily be found with a . Give it a whirl.

 

Yep, thats what I was looking for ..
but holt sh** ..not all chromed out like that
thats gotta be some serious HP ...


Scary, and yet .. calm and soothing to look at :hail:

 

Ah yes, 5 extra hp for every crome part. Seriously though, other than the wow factor, that's not too great of a setup. I don't care how many outdated, inefficient, non-intercooled blowers you feed your engine with, the boost and power output will be limited by detonation just the same as with any other blower. Now take an up to date blower with a decent efficiency rating that is sized right for your desired power level and intercool it and you'll outperform that dual setup all day long.

I guess it just depends on what your looking for.

 

I want a nice G-machine.. but something I can
drive everyday .. or else why would I wanna supercharge
a Trans AM if ya cant drive it for more than an hour.

I wanna be in the 400-500HP range ... with no stress
on the engine.. I know you can get 600-700HP outta
a supercharger .. but can ya drive from AZ to Cali??

I really want to start with Prom tuning, I can see myself
cruisin' with a laptop by my side, adjusting the ECM at a
red light .. have power of a dragster .. then stop at the next light .. and have the MPG of a honda ...

Its seems to be the most logical way to maintain a street rod


Thanks for showen me the ups and downs of a Paxton .. I probally woulda went out and bought one ..

 

Yeah PLUS those old ball drive paxtons are very very hard to turn.... Take a new XX trim vortech which will flow 50 times the air spins with eaze...

Those 6psi paxton units took a heafty tug to turn the pully....

Id venture to say I could run more Horsepower on 1 S-trim than you would make with both those blowers... And currently the s-trim is the weakest vortech they make for our setup..

And those paxton setups were all polished or plated...there was NO CAST version available..

 

1) I can't say for sure since I only had the supercharger on for a couple of months now, but from what I see on this board most people don't have to many problems.

2) for me I get about 3Ibs of boost at my torque peek so the car doesn't feel like it's gained to much more torque, just it keeps it the same pull farther up the RPM's.

3) you should be able to get a ATI kit D1sc with 3 core intercooler for about $3500, I'am not to sure about the rest. But be prepared to do some of your own fabing and you'll have to cut up your car a little because these kits were built more for a camaro then a T/A. If you do get a kit, I got some good pic's to help you out and make for a very clean install. Hell most people don't even know I have a Intercooler!

 

Thanks man ..

A clean install is what ill want

Im happy that a ATI or a Vortec will keep the
same pulll all the through the RPM gauge

But, If a stock T/A, Z28 whatever ..
runs high 14s-mid 15s quarters STOCK
why invest 3500 in a supercharger
thatll only get ya 12sec quarters to say the least.

I could get 12s without even screwin with
a blower.

Then again, I dont have a superchager so ..
I shouldnt be hatin' on them

 

looking at the twin blower setup, i noticed the filters are right above the headers & no intercooler, that is some hot *** air coming into that motor.

 

Your dreaming.. These cars go 15s on a good day, and it will take 3500 in mods to see 12s.

You can get a used Vortech setup almost anywhere for between 1k-1500 that will put you into the 12s.

Then you can sell off the FMU, your old injectors, and BTM and buy a set of large injectors, and a '749 ecm to do it right.

Ok,

So then it comes down to either Vortec or ATI.
From what I heard ATI is alil more expensive than $1500.
While Joe said I can pick a Vortec up for that much,
thats more in my price range .. thats something
I can afford and even find on Ebay.

Is that a bad idea? TO buy blowers off
Ebay or on the net??

 

I bought mine off Ebay, and it was missing instructions, hoses, and the spacers didn't work. But, with some metal working skills, I have spacers that work, hoses that work, and a blower that works. It looked like a complete kit, but I was a newbie back then. I wont' do that again.

 

Thats not really a problem for me.

I TIG weld aluminum and steel for a security
door company ..plus, I have my own setup in the
garage. So, If i gotta fabricate something .. it wouldnt
be a problem .. Id rather have it that way.

you got a working blower off ebay, so u didnt get
screwed .. but u cant always be that lucky

 

Sounds like your the ideal candidate for a ebay blower.. You can even make your own brackets.

If you like doing diy efi stuff, check out my new setup:

Thats looks pretty beefy there ..hehe

Where'd did you get your blower at?
You did all the intake yourself with your own stuff??

Have ya got any times on your ride yet??
Im curious on how it performs .. considering
Ive never had a blown out bird.

But if I were to get a charger with nothing; no hoses,
brackets, or anything .. I would make it work ..
I would stay in my garage untill the end of time
just to mount it.

BTW, with blowers .. do you feel instant power?
or is it a gradual progression of boost??
