Vortech....with Motor

[Mikz86TA]

A guy on the S10Forum has a complete 4.3L motor with 30K miles and a Vortech blower for sale.
Motor has rockers, cam and other goodies. Plus it has the Vortech. Suposedly there was an engine shop that did all the work and thus he wants to sell the complete engine package as one unit.
He is doing a LS2 conversion now and wants $3500 for the complete package.

Not really a bad deal considering the blower kit would be $2K by itself used. A stock motor maybe like $1K with 30K miles from the local salvage yard. And not to mention a PCM tuned, a cam, rocker swap, injectors, etc.

Can't view the ad. Can you cut and paste over here?

Your looking at my 4.3 currently in my 2001 jimmy. The motor has 30,000 miles,vortec v1, comp cams, lifters, rollerrockers, port polish, injectors,also standalone system from ida automotive...All motor work was done at ida also, there is a magazine article in street trucks about this motor being built there. I also have that mag if you would like it.. the motor runs great i have no complaints,but I had just got done building my Ls2 and have no need for it anymore.. any questions u can e-mail me thanks...

Read the comments, He kept it down to only 20 psi wanted to keep it safe. LOL But yet it made 280hp and 320 ftlbs put 20 psi at a stock motor and you are gonna get more than that if it stays together. I smell something fishy. I didn't notice is it intercooled?

[Mikz86TA]

It looks to have added injectors on the front of the TB housing.
Has a cam and stuff tho it doesnt specify what.

[firefighter]

I'm just saying if he put a cam, head work and exhaust there is no reason he isn't running 250-275hp w/o the blower than hit it with 20psi it should be more.

[rentedmule]

I'm not sure that headunit is even capable of 20 psi. He'd be pushing a hell of alot more than those #'s with supporting mods at that level of boost.

* Did You Know *

Did you know that if you got a Wynjammer and its pushing 6psi with the stock pulley, you only need to add a free flow exhaust to get more PSI.

Yall discuss that for a few and Ill be back with a link for ya.

I heard that u can lose boost with to much exhaust flow...now I'm confused :confused:

[firefighter]

That's what I'm thinking you'll lose PSI but gain HP. There will be less backpressure.

[King_Ice_flash]

No, his was not intercooled. I was also questioning the 20 PSI. I would not call that "safe" on that supercharger.

What about TQ? Gotta have TQ!

[Mikz86TA]

LOL. I just wanted to see some reactions.
There is a Wynjammer kit on e-bay off a Jimmy I think it was. That little tidbit of info was in his discription.

I was thinking it could be a good deal but for a dirty looking used unit $2K is too much. Id rather get a fresh one with a PCM tuned specific for me. By the time Id ship it to Al to get it checked, get a fresh PCM tune for my ride, it would be more than just getting a new one.
Thats the way I see it.
I wonder what reserve is?

[King_Ice_flash]

There are only a few people that I would buy a used supercharger from.

"Has a 6 lbs pulley but I made 9 PSI with exhaust" WTF!?

X2 Mike....I wouldnt touch that thing with your money and I think I remember Al saying for a small fee that he would warranty it on a yearly basis. For some reason $300/ year is coming to mind, but dont qoute me on that.

[Mikz86TA]

Yup, he does.

Id pay no more than maybe a grand for that one.

[rentedmule]

$300 a year for warranty is totally rediculous IMO. That WJ looks beat but I'd trade mine for that vortech kit.

[firefighter]

What about TQ? Gotta have TQ!

They go hand in hand. The type/size of headers can manipulate TQ to a certain degree.

[Mikz86TA]

I understand that adding free flowing exhaust, etc can add HP and TQ even if you have a SC or not. But adding 3PSI? I just dont see the effects of compressing air by a a SC being effected that much.
Id have to see it tested with the proper equipment to beleive that. Kust my opinion

[rentedmule]

I wonder if he just meant that he was using a pulley advertised for 6 psi but he was actually seeing 9? I've seen some reviews where they saw 12 psi with a vortech kit right out of the box.

Im not saying that it cant happen, but that would be a liability on any manfacture, if air flow was not tested prior to shipment...

I could understand +/- 1 maybe 2 lbs but not 3-6 lbs more
When I had mine, my gauge read 7lbs but who knows how even accurate that was. I just was stating that by changing exhuast does not net more boost

Definately, I wasn't disagreeing, just passing along the info. :thumb:

[firefighter]

All the info I've read on Supercharging says that a free flowing exhaust will lower you psi as per the gauge but you will net more HP/TQ as with any exhaust mod. It basically comes down to less back pressure = less pressure retained in the motor. So if a pulley is advertised to produce say 6 psi on a stock motor that can be turned into say 3 psi on the same motor with some head work and a free flowing exhaust. And the motor with the extra mods "should" make more power it also will be able to have a smaller pulley put on it to get back up to the previous 6 psi for even more power. Also PSI can be lost in an intercooler whether it be A2A or W2A just because of "friction loss"/Restriction.

It just goes to show that every motor is different. And that is why even a bone stock vehicle can benifit from a good dyno tune. A dyno tune can account for the variables.
