Can anyone help me with some good tips on which supercharger would be the best to put in my '05 GT? I am looking at the roots chargers (saleen, rousch, whipple) and the centrifugal chargers (vortec, paxton, pro-charger). I have noticed that the centrifugal chargers put out quite a lot more power than the roots chargers, so why would I want a roots? I have my mind set on the Pro-Charger system, but I would like some input and advice before I make such a big purchase.

Thanks.

 

Paxton Novi 2000 or KB are the way to go.

BTW, we've got a power adder forum.

 

oh ok, good to know. Thanks for the help.

 

How come you would recomend the Paxton?

Thanks,

I think the Paxton NOVI 2000 can support up to 1200hp. That makes it a very good choice if you ever decide on making big power in the future.

 

i agree...but if you're just looking to max out your stock block grab a Vortech SQ trim

 

The 1st thing you should understand is the stock engine in your car can only reliably support about 450-460RWHP.. any more than that and you are living on borrowed time.

The next thing you should decide is if voiding your factory warranty is important to you. If you do not care about voiding your factory warranty then there are alot of choices. BUT, if you want to retain your factory warranty Saleen & Roush offers a drivetrain warranty.. BUT Roush blowers DO NOT DO WELL spinning past 8PSI. In fact, they do not gain anymore HP because of excessive heat produced from the blower being spun too fast. So, Saleen would be your only choice and it would be a good one.

You then need to decide where you want your boost to come on.. Twin Screws like Saleens & KBs have 80% of their TQ come in on at 2500RPM have almost all their power down low where 95% of the peopel use it. If you want to REV your engine and want the power to come later get a Centrifugal...

I personally have a Saleen in my 2006 GT and love it... it has 410RWHP with the Saleen Tune and retains the factory warranty. We're going to be tuning it ourselves pretty soon to see how much better we can get.. we expect about an additional 40-50RWHP...

 

Thanks.

Do you know what kind of 0-60 time and quarter mile I could be looking at with the saleen supercharger? Also, I was told from a Ford Shop guy that the new mustang engines can go up to 600hp. with out compromising the engine or chasis. Is that true?

 

0-60 & 1/4 miles times will depend of factors including suspension, drivers, & tires. With the blower and a ok driver you should be in the low 13's and high 12's. THis would be with crappy stock tires.... but you should be able to dip to the mid-12's and with a good driver and slicks maybe low 12's.

There is NO WAY the engine can support 600HP reliably. NO WAY.

 

One thing to remember is that a twin screw such as KB or Whipple are not root superchargers. They compress the charge by a different, more efficient method. I would look into a KB setup.

 

my procharger p1sc took my 02gt automatic to high 10s low 11s on pump gas with stock heads and cams. d1sc on the 05gt is what i would do

 

KB or Paxton. The nice think about the Novi is that if you decide to build your motor, it can support up to 1000 hp. This means the blower won't ever have to be replaced (unloess of course you want more then 1000 hp).

I believe they now have a Novi-2200 which is what they use on the new Mustangs.

 

V-O-R-T-E-C-H

 

Good option too. But, if you have plans for more power down the road, you will have to ditch the blower for a larger one. Other then that I would go with it.

 

Another of the occasions when I have to say I'd go the Saleen twin screw route for all of the reasons Apexmotorsports spelled out. That's the single best solution for most people that just want more power. If you want to race, then build the motor, drop the compression and slap on the vortech SQ or T trim or novi 2200 and have at it. The Saleen is by far the easiest choice.

 

vortech sells other trims other then the SQ. just get a T-trim and be set.

 

I'd go to the Kenne Bell web site and read all they have to say. They are very knowledgeable and have been around for as long as I can remember. They have an 8.5 psi kit with no other alterations that makes 450 rhp. And this blower supports pulleys up to 25 psi. over 800 hp. When I get blown this is the way i'm gonna go. I was an auto tech and mechanic over 25 yrs so I do have some experience. Good luck no matter which system you try. note: bone stock terminators made only 366 rwhp. I think this kb system is a real monster.

 

vortech is better

 

+1 for Vortech T trim if you plan on making serious power, if not just the SQ trim

 

bone stock terminators made from 330-ish to 390-ish rwhp. I don't know how many you've strapped to a dyno or what altitude you're at but I'm at sea level and after strapping dozens down to the rollers that is what I've seen. 366 is such a perfect number and a helluva accurate average but you can't say they all made it cuz they didn't.

I'd start with the T-Trim if you're going to get a centrifugal. It's kinda big for a stock motor but you'll make more power and boost at lower compressor speeds. KB kits are actually my preference. You can make more power per pound of boost on a twin screw than almost any type of boost execpt for a turbo of course. twin screws are just sick efficient and they make boost nice and low in the rpm band so they're great from just off idle to any insane redline you've got in mind.

If you can afford the KB... take it. Otherwise T-trim.

 

Kenne bell hands down

 

A vortech runs like turbo on the top end. Its just the low end where youll see less tq than a turbo
