MD is the same way...

I can only guess they didn't use a M90 on the 350z kit because the hood would have looked even more ridiculous.. I'm sure they learned their lesson and will go a different direction this time (if they want it to sell).

Psh i live in wisconsin they only ask you to get your car inspected if you piss off a cop and he decides to give a non conforming citation for exhaust that is to loud, or if you restore a salvaged vehicle. unless you live in milwaukee or madison then you get the SEL check.

Here in miami you need to speed past a cop with open headers to get pulled over for that type of thing

Yeah sorry wisconsin pulls you over based on the car your in and how it sounds mostly. You drive past a cop in a camaro or a mustang with open headers and you'll be fine unless your speeding(I've done it). The Synchro Rev match gets left on and you rev going down into first rolling up at a light and he's looking at you dirty. I LOVED seeing this integra with straight pipes going on to the highway at a bit faster than normal speed and a cop was coming the opposite way under the highway pulled a U turn and pulled the guy over on the ramp and popped his hood. Dude wasn't even speeding so they probably gave him "unnecessary use of acceleration" (which is one of the 5 or so catch alls)

+1 :iagree:

the GTM supercharger kit is "more than 50%" done. a representative said both their S/C & TT z34's will be featured in SEMA.

he put links to their page
and i checked it out.

it said 450rwhp for S/C
500rwhp for TT

i wanna see the final product of the S/C kit..

is 450rwhp with a pulley drop or stock pulley?

450whp I imagine is with stock pulley and more reliability in mind.

450hp would be perfect for a dd street set-up, I'd like to get at least 350tq, which I think is possible

+1 on that. I think it's very feasible to see around 350ft lbs and 450whp

Here what i posted in the other thread

Sam

hey sam, 450hp is PERFECT for my DD needs, but what kinda TQ numbers can we expect?

450whp is no joke

Any love for the G37?:tup:

Of course, In the works as well . but 370z will be first since we already have a force induction solution for the g37 .

Sam

Any plans for a Non-Centrifigal blower?

I think this thread was opened for "Stillen Supercharger estimates???".

lol but stillen seems to want to not let even a mew out of their bag of cats lol

It's all good, when I made the thread the only supercharger I knew of for the 370Z was the "secret" stillen kit

is there a price estimate of how much this supercharger will cost?

^ Im guessing it will be at least $5,000

I'm not super familiar with superchargers but I am slightly familiar and I've seen people asking for twin root and stuff but wouldn't a centrifugal work better for higher numbers and still getting that immediate response ?

No offense but that wasn't a great link, not bad, but not great. I understand how they work, I just don't have a lot of experience with them and don't understand why people would want roots(which i was under the impression sucked) compared to a centrifugal.

roots makes low end torque, where a centrifugal is like a turbo and needs to spool up, so it makes its power in the upper rev band.

I've installed and driven both types on 350z, and I preferred my roots to the centrifugal. On my C6, I went with centrifugal, which I preferred over the Callaway roots that I drove at a corvette school. The corvette already has a lot of low end torque though.

if you go roots the best one on the market right now is the TVS eaton unit, but why bother with roots or centrifugal when you can get a whipple twinscrew that has the low end of the roots and the high end of the centrifugal, yet requires less effort to turn and provides cooler air charge temperatures?

If the whipple is so perfect then why are people even bothering with the roots or centrifugal? There has to be a down side.

Whipples are harder to manufacure, require very close tolerances and so have been traditionally more expensive.

$$$$

Will the Harrop TVS fit on the 370z? If it will with the right parts im going to shoot myself. I bought one for my cobalt and then sold it when i got the 370z..lol.

I had a whipple charger on a 1998 4v Mustang cobra and it made 3psi boost at 2,000 rpm, 4 psi at 2,500, 5psi at 3,000, then 7 psi from 3,500 to 6,000 then 6 psi from 6,000 to 7,000.

In my experience that level of performance is somewhere between roots and cetrifugal. Back when I had it, guys with Vortech and Paxton kits with 7psi were making about 40 hp more than mine (I was getting 375hp at tires), but their peak power was around 6,800 rpm (fuel cutoff = 7,000) where my preak power was at 6,000. So the whipple design does fall off some at high rpm and you do get boost at any rpm (because it's positive displacement), but don't get full boost until you are at 50% or max rpm.

way to kill the thread Phi.

was that one of the old single port whipples or one of the new ones with the redesigned intake side? Whipple went through and changed the front side of the blower to give it the equivalent of a TVS type upgrade. I was thinking of using a KB unit but you would have to buy it used as KB refuses to sell them in a non-kit form. I could only see myself using centrifugals if I used 2 sequential units that would switch over to parallel for increased low end and that would be tricky. I already plan to run wastegate after the blower and an intercooler so i will have more of a turbocharger level of control over it. That way i can pulley the car for 600 and set my boost level with the wastegate for even more low end. My goal is to have my little 3.7L pounding out torque like my friends 6.0L GTO. Then Imma gonna pick on all the v8 stangs in town with a rear bumper sticker that says "what it's just a 6?";)

Oh and to Snakes if you bought it sized for a cobalt it isn't anywhere near big enough for our cars. The blower should have about a 600hp capacity.

Im looking at replacing my m-62 on my stillen 2003 SC with the 1320 tvs. I have talked to Performance superchargers and they will match it to my exisiting stillen kit, The only problem is that i have to drop the compression of the moter to 8.5 , as it will make 16 psig of boost. They estimate 420 rwhp. It will fit under the stage 2 hood. The TVS is a huge improvement over the M 62 and M 90. A lot less heat and more effecant. I turn the m-62 stillen at 10.5 psig boost and its not even 52 % effecent. I have cosworth heads and GTM Sc cams for this project.
A 1320 TVS on a 3.7 would be nice.

I know I have a question and I am guessing many others are also interested in the answer as well. I would love to have a forced induction system (especially since I am at 5500 ft. elevation and am already loosing over 20% from that alone) but to use Ron Popeil’s term, I would like to “set it and forget it”. I would like the highest gains that are safe for the engine. I would not like to have the lifespan of the engine reduced by any significant amount. I do not want to have to take it to a tuner after the initial setup and install and initial tune. Basically I would like the overall reliability to remain while performance was greatly improved. Is this possible? Am I expecting too much? If I wanted 375+ rwhp, should I have bought a car that came that way from the factory? I would love to hear from GTM and Stillen about these questions. Thanks for your time and attention!

Do you really need to post the same question three times in the top three threads?

(And 'yes', I have to post my same question three times to make a point)

I would have totally answered that question if you hadn't rudely spammed it across the board. Seriously, that's impolite...

The post was "spammed" to the threads of the epople I was requesting a reply from. GTM and Stillen. I find it interesting how you were offended that you were forced to have your eyes glance over my post two additional times. Doesn't take much to set you off.

Honestly, once is enough, the reason people are mad is because they are following these threads, as I am, and its a little annoying to see the same question asked on all three of them. You more or less hijacked all 3 threads and now we have to read the same answer to your question three times just because you are impatient. Think about it.

Yeah, and all it does is get people giving different answers to the three threads, it's like holding three separate conversations with people at the same time.
