ok the vortech and procharger websites suck with giving specifics.

i wanna know which kit would be more bang for the buck, as well as reliable. both kits are about the same price, but both need fuel system upgrades.

main diffs:
- procharger has intercooler
- vortech taps into the oil pan

get the procharger it comes intercooled. you will need to get a good tune (contact american motorsports or vmp) and also a 300lph fuel pump, bigger injectors, bigger maf (70mm).

but the bad thing about procharger is it robs more power

if it were me i'd get a Turbo setup however if i had to get S/C
Vortech
bigger pulley
Intercooler
fuel upgrades
and a damn good tune

but remember with FI your going to be running a little faster than bolt on 99+GT's but if that GT goes FI your toast

From some Guys/Gals with experience with both said:
Internal step up on most prochargers is almost 5 to 1. MOST vortechs are about half that. Try and spin each blower's pulley by hand. The vortech will make a few revolutions. The ati will be lucky to make it 3/4 of a turn after you let go. Now imagine a belt trying to turn that same pulley loaded down with boost...

I've owned:
Vortech A, B, R, S, and T-trim blowers.
Paxton SN-*, VR4, Novi 1k* and 2k* blowers.
Ati Poocharger P600b and D1R.
Powerdyne garbage...dont even remember the model number, I saw the internal belt and about died laughing...

When I ran the D1R, had some issues with belt slippage (imagine that!)...called ATI for some tech support and they said tighten the belt. They said tighten it till it snaps, and then dont tighten the next one quite as much...

The bracket sucked. Flexed pretty badly-I'll try to find a pic of my old custom blower brace Long story short, I will not buy another procharger, no matter how good the deal is.

Heres a little story, back in Feburary of 2002:
Car#1.) DSS Bullet 306, Ported Trick Flow(300ish CFM) heads and intake, ATI P600b intercooled setup pulley'd at 21/17psi*, speedbrain engine management and about 6 hours and countless pulls tuning on the dyno- 471rwhp.

****Procharger uses 21/17 to rate the boost because they loose at least 4psi over their intercooler..imagine what a Vortech would do making 21 psi *******

Car#2.) Stock shortblock, Edelbrock performer RPM heads and intake, Vortech S-trim with a 2.65 and 6.785" pulley(approx. 18psi), no intercooler, stock A9L, 3rd pull on the dyno just messing with Fuel Pressure Regulator and Distributor.
613 rwhp(baseline was 577, second pull was 599).

That was all the proof I needed. First hand the cars sounded and behaved dramatically different. Sure ATI's claims that intercooled boost is more efficient are accurate, as long as you dont mind comparing 20psi to 15psi at the blower's outlet.

yeah, the vortech is more efficient. People are getting the same power with the base vortech kit as the intercooled procharger

yah the procharger is nice but after looking into it i found out that torque is robbed with a procharger, so i'll either go with a vortech or a turbo setup.

Can you get the s trim & get the aftercooler later?

you can buy a custom intercooler later for the vortech... but you will WANT an intercooler they are just to good not to bother with

Thats intresting. Ill have to see how much this is true when I go back in for another tune. I personally dont have any belt slips or anything. Maybe I just happen to be very lucky cause Ive had ZERO issues so far *knocks on wood*

Also mail order tunes are teh suck. Id NEVER get a mail order tune cause its NEVER right. Im thankful I have two shops that know how to tune :good:

Tuning a supercharged motor is very important, especially in high boost applications. Very critical that it is precise.

thats not always true. I know a few people who made their car worse off and or couldnt even get it out of their driveway.

you have to go around the world or so it looks to get an intercooler on a vortech, at least on thats on the front bumper as you would want.

It is an aftercooler & the one that is mounted in the bumper is procharger.
