I have a Vortech Supercharger. I like the kit but I really like that turbo boost. The Vortech is loud and has that linear boost, don't get me wrong it still goes. My question, is the Turbonetics that much faster and is it worth the cost to do this.

 

swap the pulley and get it tuned.

I am pretty sure the SC-trim vortech headunit has more headroom in it than the turbonetics 60-1.

 

On a stock engine, it will never be worth doing that swap. You'll be out a lot of money for marginal gains over what you could do if you follow Quadcam's advise.

Its not worth doing the TN kit, Then there is a lag issue. And yes follow QuadCam's advice...I couldn't say it any other way

 

as far as what I was saying. There is a drag race class called Real Street at www.nmraracing.com. This is a mustang only drag race series. For the real street class, they are severely limited in what they can do.

3200#
single power adder (vortech S-trim, Novi 1200, single stage nitrous, etc, NO TURBOS)
NO head porting
small cams

you get the idea.

These guys are running low 10s and high 9s @ well over 130 mph with an S-trim or similar blower (no intercooler!!). also, 3200# is easily achievable in a Z.

Vortechs are fast, but not many Z/G guys have figured it out yet.

 

A Vortech or any boost on a 5.0L + engine is completely different than boost on a Z(meaning the max hp will be much greater with more displacement)-if you think the stock Vortech blower could propel a Z to even 120mph traps your crazy. Id say the TN 60-1 turbo has the same HP potential as the Vortech, of course with mjuch more TQ. I agree though, get a pulley and tune the motor, if your on the stock block its not worth the swap.

 

I don't have a TN ST, but I did have the Vortech. I swapped it for a greddy tt kit after 3 weeks on my car. I can't tell you that it's a total different feeling. Even if going turbo wouldn't make the car faster which it will the arsehole pucker effect is much better with a turbo. IMO it's worth the loss of $$$ if you can afford it.

 

If you can find someone to buy your blower and have the money to make switch go for the TN tunner kit get get the extras that you need and get tunned. But if it were me i would change the pully get re-tunned and see if I like it" if so keep it if not sell it"

 

what lag? Does the vortech kit make a solid 8psi at 3500rpm or sooner? I highly doubt it. SC owners are always dissing turbo lag....well, want to know why the vortech doesn't make the torque numbers? Because it doesn't hit full boost NEARLY as soon as any other turbo kit.

Sorry, but that's a dumb response, when TN kits are trapping mid 110s on street tires at stock boost settings.

 

the blower isn;t acting any differently on the 4.6 or 5.0. It still has the same impeller and max airflow. Your boost numbers may be different, but max airflow isn't going to change. Also, if you look at the class that these blowers are being used, they can use aftermarket heads, but no porting. Even with the heads used in these classes, the VQ head is probably a better head.

 

So you think a standard Vortech Z even with a built bottom end can make 550+whp to put it in the 10's or trap 130mph? Never

 

Even with the T-trim blower and a 3.12 serp pulley and a 34 tooth cog pulley [ which is about the same as a 2.87 pulley ] I make 5.5psi @ 4000rpm . That still isnt close to what the ST can make at 4000rpm's .

On a V8 Mustang the S-trim is going to flow more air than on our QV's because it has two more cyl.'s to pump the air.

To the OP . I would have to agree what others have suggested . Put a smaller pulley on , save your money up and go TT not ST . If going to a turbo'ed car is what you really want , go all the way not half .

 

I had a Vortech till last week making pretty decent numbers but I wanted to achieve more power sooner than 4000rpm which is what was happening so I decided to get a built motor with an APS TT but in your postiion I would just upgrade the pulley and be happy until you feel the need for even more power....and sooner in the power band, the make the switch over to a turbo setup and build the motor.

 

i'd keep the vortech and upgrade the hell out of it until something happens to the engine. Then I might consider ditching the vortech for a turbo if you'd have to build up the engine anyway.

I do kinda wonder how much stress the crank bearings etc can take with a vortech pushing like 20 psi if it were possible. That and there's going to be a lot of new engine stuff coming out soon - the 2007 VQ35 is going to be a lot different than the current ones and Cosworth is working on some stuff too I hear.

At least that's my plan. Stick it out with the vortech for awhile anyway and just see what the options are in the future. For bigger power numbers, I would opt for a TT over a ST since you can use a real dual exhaust setup and not have to merge the exhaust manifolds like you would with a ST

 

hope you guys dont mind but I am in the same boat. I have the HKS SC and just need more. could somebody tell me the diffrence between stage 1-2?

charged: Hope you dont mind bro but I thought I should post my set-up to help you and others in this topic. I was talking with dave (old AAM GM) and sharif about adding a larger IC and 100mm pully but cost wise I might as well go ST/TT


my set up now:
-complete CNC short block
-Pauter Billet Forged rods
-ARP Rod Bolts
-Arias zero silican AM Extreme duty pistons 9.0.1 .020 overbore
-VQ 12mm studs
-TurboXS UTEC
-HKS supercharger
-JWT cams
-DC sport headers
- AAM test pipes
-AAM 3” max flow true dual exhaust
-AAM version 2 fuel system
-AAM plenum spacer
-440cc RC injectors

 

I can't imagine that HKS blower will flow very much at all

 

If the SC-trim is capable of moving air at 1000 cfm, how is having a V8 going to make it pump more air? I understand that you are thinking a V8 has 2 more exhaust ports and you can pump more air out, but the heads on those mustangs can only flow about 200 cfm (at lifts higher than those used on the 10.0 @ 130mph cars I was mentioning) on the exhaust ports.

I know that I am only theorizing here, but it would seem that there is plenty of capacity available.

It could be that alot of restriction and pressure drop happens in the long piping and Intercooler. A the PRI show, one of Vortech's guy said that the only reason they used an FMIC on this kit was to appeal to the "tuner" crowd. The outlet temps on a centrigual blower are significantly lower than on a turbocharger.
