GTM Supercharger Stage 1 with Fast Intentions long tube Headers & 12" resonator exhaust

Dyno: Dynojet
Red line - Right after SC was installed and getting around 5-6PSI
Blue line - After some tuning and updated intake piece with 8PSI

No way you hit 8psi with longtubes...
:stirthepot:

Almost 400, nice!

nice #'s

your lines are all squiggly like spaghetti :bowrofl:

Nice numbers! 93 or 91 octane?

93

nice dude!!!!

What kind of dyno is that?

dynojet

looks awful. :shakes head:

Correct, sorry it got cut off in the scan.

Are you happy with those numbers?

Very happy, I wanted 8PSI with 400HP and I got it. I am sure we could spend more time tuning the top end and do more work increasing that flat spot at the end but no need for me personally.

I'd like to see it without the LTHs, but pretty nice numbers still. I like that torque curve.

How's the drivability? Car feel pretty livened up?

Nice, I am glad someone got F.I.'s Long tubes to work.

Any vids/sound clips

Funny that without tuning, you'd have only made about 40whp over someone with bolt-ons.

Driving is the same, just with boost now which I seem to get into more than I should. :shakes head:
It does, the bottom end has a nice feel to it, which is where I wish the TQ was from factory.

I bet it's slow as hell :koolaidwall:

5-6PSI in July does that to our cars here.
A 350zHR with a vortex the same day was putting down around 380 at 8PSI on the same dyno so it definitely was not a fun day for making ones e-peen bigger.

No free ride for you now, 10 bucks to look under the hood, 25 for a short ride.

After it got off the dyno I slapped myself because I did not get a video, it will be put on my list of things to do in March.

damn, you're more expensive than your mom!

:facepalm:

good prices:rofl2:

I think you lose bonus points for no vids

I think that these numbers are respectable! I am glad to see that you made 8 PSI with the GTM SC and our headers. This is proof that the headers worked all along with the kit. The kit just had other flaws and now it seems like they are rectified.

Now you need to pulley that damn thing down, make 12 PSI and get those numbers up. Maybe the stage II or III kit will clear 450 at the wheels!

Sorry to respectfully disagree.

So...GTM advertised 460whp at 8psi on 93 OCT w/ 2.5" exhaust and 420whp @ 8psi with stock exhaust in their press release and Dreamer made 394whp with longtube headers and full exhaust.

Here we go again.

That is what they claimed but has anyone with their kit that has done an independent dyno ever achieved that? If so, it would be news to me! From what you wrote the numbers do not add up.

Boost is back pressure. The stock exhaust is as restrictive as it gets. When you relieve back pressure in a force inducted application, you have a PSI drop off but you pick up torque and power.

Now it seems like this SC is capped @ 8 PSI. What that tells me is that no matter what you do to it, it cannot move enough volume to move more air than 8 PSI.

Put the larger stage II or III head unit on it create more volume and turn the boost up, period!

The garbage idea of leaving a stock exhaust on a force inducted car is one of the most outrageous things that I have ever heard...

I hope this doesn't turn into another flame thread :facepalm:

TBH i really do like that torque curve. Plenty of power throughout the band, I'd love to have that for Rin.

:stirthepot:

Are you talking about a vortech kit if so they dont make a kit for a 350z HR the do make it for the DE 350z If its 8 psi thats the normal numbers for a DE.

The one thing I notice about all the GTM supercharger dyno's is that flat spot up top most of the times a centrifugal supercharger will keep building boost all the way to redline.

I hope it doesn't tune into that either. I am actually happy to see that someone made 8 PSI with the kit and my full exhaust. It goes to show you that it all can work together when all of the components are doing their job!

Now as far as making 460 at the wheels, c'mon thats bogus. The Stillen/Vortech head unit moves much more volume and to the best of my knowledge they haven't even seen those kind of numbers, (YET)!

If you want to make 450+ you are going to need to turbo the car, plain and simple!

I think the vortech Blower can do It it just hasnt been done on a 370z but has on a 350z. I hope to be the first with the unit to do so with my custom set up I am just waiting on my exhaust from you Tony I hope your feeling better this week lol.

I cannot wait to see what you can achieve with it! I am feeling better, thanks for asking...

Tony

460whp is what intro level TT's are running, are we to believe that the stage 1 SC and TT make the same power? Still I'm with RCZ on this one, GTM led us to believe more, clearly the stage 1 compressor is not enough.

BTW I'm a huge fan of Tony's long tube headers. Every SC setup I've ever seen, headers and exhaust setups at 2.5" have increased power not robbed.

Shumby made 390 rwhp at 6 lbs with stock exhaust manifolds and stock cat's. Not sure what exhaust he had.
Headers and high flow cats will cost you boost and RHWP.
