vortech help I have a 2002 trans am that I bought with a vortech supercharger on it with charge cooler already installed. I took it to a local speed shop and was told the highest boost it made was 5 pounds. Does that sound right? I am not a mechanic by no means so any help will be great. The car has 10,000 miles on it headers,borla exh, hi flo cats if any of that matters. I am really worried about hurting the motor since I do not have the original programing. Should I buy the diablo setup? And what should I do to get some boost out of this to compare to the turbos like sts power? sorry so long of a post im new to this thanks
Vortech rates that kit with stock manifolds at 9PSI. Having the longtubes should drop the PSI but retain the power (this is a good thing). You shouldn't worry about how many PSI you are seeing but more so how much HP you are making and the speed you are spinning the blower to. I used to own the kit you are talking about but never installed it due to the small head unit. The vortech g trims are good for high 500ish RWHP (i think).

So should it drop it down to 5 pounds? from 9? and Should I buy a pully to up the boost or leave it alone? I am really confused about this because I dont feel the boost like in a turbo car or like even in my wifes saturn ion redline. It feels like a constant pull through the rpms , no change. thanks for the help

Just a little clarification you don't know what else was done to the car right? I would guess it has some kind of tune in it right now. I would have it dyno tuned with a wide band and see what you are makeing right now and how safe the tune is etc... There is a lot that can be done with these kits and a smaller pulley is just the first step. I don't know where you are located , but do some research and see who the nearest person to you that specializes in FI LS1 cars. Call get some priceing info and make an appointment when you have the money etc... And they have a very smooth feeling powerband not peaky atleast in a mild modded form.

do not go down to a 2.75 pulley. Too many factors that we don't know of yet. On a stock kit my car would instantly pull 5 then creep to 7 right at 6,000 rpm and then shift.
Do not use the diablo. Take it to someone who knows how to tune forced induction cars with ls1 edit.

I am trying to find someone close to nashville tn, It has bmr suspension, borla exhaust, hi flo cats, headers, and the vortech with cooler. I also had a mcleod clutch,pressure plate and the rest put in recently with a pro 5.0 shifter. I just get really dissapointed when I take my car somewhere and it stays for 2 weeks nothing gets fixed or changed and I still get a bill. Wish there was someone around here that knew what they were doing. The shops around here say they are using diablo instead of ls1 edit now cause its better? see what I mean.

no luck. These guys here want me to sell my vortech and buy their sts kit. Really hate to change all that out and buy something else. I guess Im just going to have to keep looking for a tuner for ls1s close to nashville, I would even drive a couple hundred miles for a good one.

If they are telling you that Diablo is better than Edit that is cause they don't know how to use it LOL!

oh yeah 12 bolt rearend.I will take pics tommorow to post for all to see. still new to this computer stuff.The car came from salt lake city all fixed up like this already. The guy that owned it is supposley in prison and his parents wont tell me anything about where the car was worked on all they would say is that he bought it new for 30 and then dumped 20 more into it. When I got it, it only had 6000 miles now its got 10500. not bad for an 02. Just want to get it right.
