Personally, I think that if you want 450whp on a mustang dyno, you're not going to get that from an SC kit...you want a TT.

I think I've essentially maxed out the stillen SC at 9psi. I guess I could go 10 psi and make like 465-470, but at the expense of safety...whats the point.

Your not close to maxing out that blower there are a few thing that you can do to bring up boost and make more power safely. This has been done before just on 350z's and not 370z's I should have some results soon.

To the OP most people on this board have the GTM kit than the Stillen kit due to the tuning issues that some people have had with the Stillen kit.The info is out there if you go with the Stillen kit make sure you get a custom tune.

Ya I know I have been looking into both but I wanted to hear from people who have actually purchased both or one of them just to see what they have experienced from it. I would like this to be more of a this is what I have and how I feel about it kind of post, I just hope it doesn't turn into a disaster like the Motordyne M37 did LOL

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.

No no, all I meant was that I don't think the kit could make any more power at 9psi. Perhaps if I got longtubes and those could flow a bit more. I know the blower can do a lot more, but the point im trying to make is that you have to push the sc unit past 9psi if you want to make more than 400 on a mustangdyne dyno.

Its all about the tune

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.
