Superchargers for the 370Z?
 

Calling all sponsors/anyone with any type of info!!!

Does anyone know if there will be superchargers available for the 370Z?

Is Vortech/HKS/ATI/Stillen working on anything?


Please don't turn this into a TT vs. Supercharger debate. I've already been the TT route on my 350. I want to try something a little less complex this time around and won't be looking for much of a power increase.

Thanks

It's a little more difficult to S/C the 370Z since it is DTB. There was word of a twin centrifigual S/C setup from Vortech for the HR motor, but I haven't seen anything yet. I'm still trying to figure out how Stillen would make a roots style work with the DTBs. Maybe they can chime in. It's all going to come down to how you route the piping. If you can get the brackets to work on the motor; then you should be able to get the piping routed.

There is this:

Filed under: Tuners , Supercars , Nissan If the Nissan GT-R’s 478 horsepower twin-turbo engine isn’t powerful enough for you, the tuners at Power Enterprises has some hardware to put Godzilla over the top. PE has two kits available and a third coming to the Tokyo Auto Salon in January. The 35GTR 560 (as in 560 hp) kit features a PE P-Map ECU, PWR Air Impulse II air filters and an upgraded intake kit. The 35GTR 600 kit has the above upgrades, plus upgraded wastegate actuators and a Supersonic Titanium 89 mm exhaust. For those among the GT-R crowd that could simply never have enough power, Power Enterprises is also working on a twin-charger setup that adds twin superchargers to the mix. the Four Charger System adds a pair of Rotrex C30-94 superchargers to bump the power quotient to 650 ponies. More importantly, the superchargers should provide nearly limitless mid-range torque, making turbo lag a non-issue. We’re guessing track day would be a hell of a lot of fun with that setup, and we’d imagine that a twin-turbo, twin-supercharged GT-R would sound something like Doc’s time-traveling locomotive from Back to the Future . We’ll be on the lookout for more twin-charger details closer to the Tokyo Motor Show on January 9.

Probably be the first twin charger 370Z owner!!!

^ you do realize that kit is for the GTR not the 370Z right?

If yes, I'm confused as to what you meant by posting it.

Im sorry, but what does DTB stand for?

Dual Throttle Bodies (2 intakes) :tiphat:

I saw a root-style supercharger kit for the G37 on here somewhere. I think Shumby posted the pic. It's still dual throttle bodies, but it replaces the manifold (like any good root-style charger does). I'm pretty positive it'd fit under the 370z hood.

It's not twin charger though, but I'd imagine it's going to be good for a LOT of boost.

Centrifugal superchargers are junk... Don't bother with them. They're less efficient than the root-style for comparable boost. Newer root-style blowers don't even sacrifice gas mileage like the old ones and the centrifugal ones. (MOSTLY the centrifugal.)

Although, you can get a BIG sea-shell to make massive amounts of power, unless you're drag racing (which I doubt you are since you picked a Z) it's not worth it.

:werd:

Thanks for all the info guys. I had actually forgotten about the DTB's since my last three VQ's were single. I guess superchargers may not even make it into production this time around....

I apologize for the confusion, I meant, you could do some research and perhaps come up with something similar to that of the Twin Super Charger setup. Although, would it be possible to have two belts coming off the crank pulley?

^^^ It'd be easier just to have one LONG belt! LOL

http://www.the370z.com/lounge-off-to...html#post24272 <--- FOUND IT! :)

Are any companies developing a supercharger kit for the 370Z yet? I'm really interested in supercharging mine since I don't want the huge power gains/costs of a twin turbo.

Honestly, I'd like to see a twin super charger kit for the Z. It's got the perfect platform for in.

Just to clarify...It would actually be ALOT easier if we could use our standard, Eaton supercharger on the 3.7 dual throttle body engine's. We would basically just replace the manifold like we did on the 3.5 liter's and design a hammer head style intake tract coming off the throttle bodies. It would look awesome and work really well. However, the current supercharger that we use on the 350Z liter, 62 CFM displacement would be undersized for the 3.7 liter. We would really need to jump to the larger 90 CFM blower which unfortunately creates the need for a new hood.

Development on our forced induction kit is coming along nicely.

Just speculating but it sounds to me like the roots style is out for Stillen on the 3.7? I've also read that it's near impossible to get carb exemption for a non-factory turbo (which means Stillen probably won't be attempting that either). So this leaves only belt driven centrifigul blowers, vortec etc. Can we get a teaser? Maybe a brand name of blower? Is it rotrex? I like rotrex.

I never said that Eaton was out of the question...Just trying to do my job and make my posts regarding this subject as vague as possible hahaha.

You are correct that it is pretty much impossible to get an aftermarket turbo kit CARB legal though.

Seriously though, right now we're just not ready to let too much out of the bag. We're not far from being ready to really get you guys hot and bothered. I really appreciate all of your patience on this. We're holding our cards pretty close to the chest on this project!

Well just hearing that you guys are working on something in the supercharger department and posting in this thread is already enough to get me excited. I won't be supercharging my 370Z till next year anyway, which will hopefully be enough time to develop a great system. Looking forward to see what you guys come up with!

Do you think you can come out with an option of a bigger supercharger. The 350z supercharger kit was a big letdown. Maybe something rated for 500+ hp this time.

We don't drive a V8. A supercharger that nearly doubles the stock hp output will be overkill and won't be as reliable. I'd be very happy with a 400 whp supercharger kit.

For starters- I am at home right now and read this thread and can't remember what my password is so I had to create a new screen name hahaha...sorry...

Welderz-

The supercharger for the VQ35 liter engines that STILLEN developed achieved every one of our goals. It was not intended to be the highest horsepower producing forced induction kit because at the end of the day, that only matters at the drag strip or the dyno.

The greatest aspect of an Eaton, positive-displacement supercharger is its daily driver and race track prowess. Because the Eaton blower produces instant boost at low RPM levels there is no lag and therefore it offers amazing torque at low RPM's...Where you drive daily and where you want power when accelerating out of corners. Also, the linear powerband of an engine with an Eaton supercharger speaks volumes of its performance.

One thing to consider with the 3.5 liter is that the blower we selected was chosen for two reasons. 1) Its size. The smaller size allowed us to make a slimmer hood...The next size up supercharger, MP90 is much taller and therefore requires a significantly larger hood bulge. Something that we feel the majority of people would not have wanted. We understand that the hood modification was a little bit of a turn-off on our kit but was worth the performance of the Eaton blower. However, the larger hood bump required to clear the MP90 is pretty massive. For an example, here is the hood that we made to clear the MP90.

Some people love it...Some people hate it...personally I think it looks GREAT but, I'm pretty unusual most of the time haha.

Additionally, the MP90 was really, too much blower for the 3.5 liter displacement engine. In order to take full advantage of a 90 CFM supercharger you really need to do a stroker kit and make your engine at least a 3.9 liter. That way you have an engine that can actually handle all the extra air coming in.

Yep. Most of the 350Z supercharger solutions came in around 80 to 100 hp gain. Any more power really needed a built block to be reasonably safe. Sure, you could get plenty more out of the turbo systems, but that really required much more extensive builds though the rest of the systems to handle it reliably.

Kyle,

Just to be clear....does Stillen have something in the works for the 370Z in terms of supercharging?

^ Yes they do. He has stated this more than a few times on different threads at different times.

I will be extremely happy with 375whp, a flat curve for the track and a reliable tune. If you can hit those goals, you have at least one customer for sure.

Oh yea...We're in development with our forced induction kit and it's coming along very nicely. Almost all of the hard parts are mounted.

I have no idea on pricing or an ETA though.

I didn't mean to offend your products. What I meant was the stillen supercharger for the 350 topped out around 400 rwhp. I understand your targeting the general market of people who want a reliable daily driver forced induction kit. It would be nice to have the base kit for the general market and an upgraded option of a higher capacity supercharger. Something for built motor high horsepower setups. You can only change the pulleys so much before the supercharger is out of efficiency.

Thanks. That's excellent. If I decide on a 370Z once the vert shows up than I'll more than likely go this route. I don't want to go turbo this time for many reasons.....

You are 100% correct and your remarks were not taken as offensive. I just forgot to quote your original post so I just called out your name...Not trying to call you out directly or anything!

You are correct that on a stock block our 62 CFM supercharger can produce about 8 pounds of boost and then it basically runs out of steam. However, that's about all that a stock block can handle. Anything more than that and you start walking the fine line of reliability.

With that being said. The new supercharger that we are working on will be capable of producing PLENTY of horsepower...I don't want to say exactly how much yet but I don't think anyone will be left wanting more with the possible options that we will have.

Greetings.

Make this happen in a stage 1/2 scenario for a daily driver, with uber reliability, with exhaust making anywhere in the 375-400whp range, and I will love you long time :)

And I want it tommorrow :) Is that too much to ask?:stirthepot:

500-600whp would be nice

I don't think you're going to see 600WHP on the stock block at all (at least not for more than a few thousand miles if you're lucky). MAYBE 500WHP, and that'd be pushing it.

Kyle:
Have you done any testing on the stock 370 block to see what it can handle boost wise?

R&D is in full swing.. we don't typically talk about anything until we have everything completely dialed in.. it's a good thing Kyle has the right last name.. :)

We'll have more details as soon as we can.. and I don't think you guys will be disappointed..

I'm guessing 450hp.

Sorry for the noob question but what is the advantage of supercharging over turbocharging?

Instant power vs. waiting for the turbo to spool. Also (arguably) reliability, ease of install, maintenance. Turbos are great but for my specific goals of about 350-400 whp a supercharger will be just the ticket.

^ I wouldn't say "arguably". In my experience, both personal and second hand, turbo systems will require almost constant attention. You have to watch boost, temps, AFR's not to mention mechanical failures, bolts working loose, gasket leaks, manifold cracks, and coked bearings. Turbo's are leaps and bounds better than they were 15 years ago; however, there are still many more parts and variables involved in a turbo setup than a typical supercharged setup. I loved my turbo IS300 and I loved my Garrett Upgraded MazdaSpeed 6 but for this car I wan to give supercharging a shot. The obvious benefits of low end torque, ease of installation, system simplicity, and a warranty that Stillen hopes to offer make it an easy choice.

I had to throw in "arguably" just in case someone got all defensive and butthurt about it.

The other thing I forgot to mention is cost. A well put together turbo system will run you AT LEAST $10k, considerably more perhaps. With a supercharger I expect to have a kit available for $6-7k. Hopefully my figures won't be too far off.

I was shocked nobody made manifold style supercharger kits of the 300zx (z32). I know that the car was designed for TT, but 5-6PSI boost from a super would have been perfect for the N/A cars!

It was done but I don't think it was a kit and I don't know very much about it. I just know that I saw a video of one on youtube...Famous last line right?
