You mean between turbo and sc? For daily driving it really makes no difference...honestly youre not going to push the car hard enough to where it becomes an issue. Turbo will give you lots of torque and power and at least the GTM TT, I know, drives very nicely when you're just cruising around. The SC does too, but the power delivery is more linear. The SC has much less torque and will strain the engine and drivetrain a lot less than the TT will. If you're thinking longevity, SC is the way to go...but since you're not tracking or driving it too often then you'd be perfectly fine with the TT.

The TT has greater power potential and will make more power at the same boost level that a sc would. The reason for that is the amount of flow and the lack of parasitic loss associated with driving the sc unit.

In other words...if you want a crazy animal with big hp, get the tt, but remember theres a bigger chance to break things. If you want linear, smooth power thats easier on the car, go sc. Both have their pros and cons.

Ya I am thinking more of longevity b/c eventually I will be in the states more b/c I can't do this job forever. Maybe I'll just buy another Z later down the road and TT it but for now I will stick with the SC. So what did you put down on a dyno and track times? O thanks by the way for all the input I am happy to see someone popping in on this subject.

I put down 455hp/335wtq on a Dynojet (same dyno that gtm and stillen use) and ~400whp/290wtq on a Mustang Dyno.

FYI I dynoed in at 256whp stock on that same Mustang Dyno...

I'm sure the GTM SC guys will chime in soon enough with their results.

Ya the Mustang Dyno's I hear are generally lower. I got 285 base from a dynojet

If you pause it at 16 seconds you can see the numbers better.

I have the GTM supercharger. I got 430whp/340tq. THere are people like RCZ that have had success with the stillen supercharger, but also some that have had problems. I would do more research on this very forum on the 2 and then ask more questions after you done a few days to weeks of reading on here, and be wary of questions b/c it can get out of hand quickly on here.

Ya I am trying to stay away from specific questions just more of what is your personal opinion on what you have. Then the normal whp/tq and track times if any. I have seen some of these threads get way out of control and takes forever just to get some real information.

I previously had Stillen kit and switched to GTM kit recently

Stillen kit made 390ish (can't remember exactly)whp and 288tq
GTM kit made 395 and 345tq
Both on 91 octane.

with the kit u have now , is it possiable to have stock back muffler with high flow cats and 3inch custom pipes ! how does it do in the hot summer ? any coolant upgrades ! thanks

I have stillen with no cats and custom tune and am enjoying it with no complaints. The GTM is in the better part of there S/C curve so they make better power and Sam seems to really back there product and stand behind it. I will not give Stillen that kind of credit. The Stillen blower is barely in the curve so a pulley change could make huge gains since it is good for a max of 22 psi according to vortex information. Right now I would recommend GTM because it appears like they are sticking around for a long time.

i thought the max was at 17psi. yeah, the curve on the Stillen kit is pretty weak. by upgrading to more boost means more risk of breaking something sooner.
