When is someone going to make a FWD VQ35 Supercharger?
There are supercharger kits available for the 95-01 VQ30 Maximas, but nothing for the 02+ VQ35 guys.
Originally this was thought to be because of the small demand for a supercharger kit for the newer Maximas, and the fact that there simply isn't enough room in the engine bay.
Well, I've stumbled across this picture of a custom kit that a guy did on an Altima:
This proves that it is indeed possible.
If someone (cough NWP cough) were to make a FWD VQ35 kit, not only would all of the 2002+ Maxima people able to use it, but the 2002+ Altima guys as well. Even the Quest. It seems like there is an equal amount, if not a greater amount, of Altima enthusiasts also.
I would think there would at least be moderate demand for such a kit. I mean, there are ton's of Maxima and Altima guys who are always looking to make more power, and now that there is 8 years of two different cars that use the same engine, there is even more demand.
This is just something I've been thinking about and I don't actually expect anything to come of this, but still.

I've seen that before. I think he took that roots-type from a Pontiac Grand Prix. Personally, though, I'd rather have a turbo for a few reasons:
- SC don't see full boost until the very top of the RPM range.
- SC are always running boost. Which means if it's in a DD, you lose some of your gas mileage.
- Boost can be controlled electronically. You don't have to buy different sized pulleys.
If I'm adding an SC, that's (MPG) at the bottom of mine and probably 99% of peoples mind when adding FI. 
IMO a roots type, like the item pictured, works better with OHV type engines, not DOHC.

Wait...what?
Nevermind. You ninja-editted...
The biggest downfall to a SC, IMO, is not building (full) boost until the top of your RPM range. I guess with an extended rev limiter like Moncef has, you could see some serious top-end gains.

When I first saw the thread on this Altima a while back, I considered trying to find a junkyard Grand Prix with a supercharger on it that I could scavenge. I don't have or know anyone that has the necessary equipment to properly rebuild/modify the kit to fit our VQs, though, in terms of properly balanced pulleys, etc. 
True for a cenrtifugal SC, but with the supercharger on that altima it builds boost a lot sooner. I would love to see someone do this on a Maxima just to see how it runs. If I remember correctly, that Altima was running mid 12's.
There was a fella that did a roots type on an A32, but got it totaled the very day he put it on.
Eaton (the GTP SC) has many different variants but IMO, if I was going to go custom, I;d also go turbo.
Also, IIRC matty, at one point was developing the brackets so that the V1/2 would work using hardware from exsisting kits (for the VQ30). Obviously the CVTC's are in the way.
There's at least one thread about it in the FI section.

If I had the proper equipment to balance the pulley shafts, and manufacture the mounting parts, I'd go for it. The First National Bank of Brett just can't fund it right now.
Correction: That altima was running 12.8 on 5.5 psi. I wonder what a TURBO 5.5 gen would run at the same boost level just for comparison.
Last I talked to Matty, he was still working on that project. That was a few months ago though.

We have dudes here running 12.8 NA .... Maybe he needs to drive better or more traction.

Correct me if I'm wrong, but isn't Matty's kit for the Vortech centrifugal SC?
Honestly, if I did go supercharged in terms of FI, I'd much prefer a roots-type over a centrifugal, to be honest.
But then again, in a community as small as ours, without any major sponorship backing, beggars can't be choosers I suppose.

But that's sorta what I was getting @.
Anyone who wants to be a guinea pig...these superchargers are running between $400 and $700 on eBay.

In a few more months, I might possibly have enough money saved up to experiment with something. But I'm not super experienced in terms of FI. Guess I'd need to hit the books between now and then.
I wouldn't mind prototyping a roots-type for our cars. I still need to find a shop capable of producing perfectly balanced pulley shafts, however. I'm not promising that I will, so no PMing me asking me in two weeks how things are going.
If I do pursue anything, I probably won't have enough time to actually start putting anything together until this December or next summer considering I'll be in school.
nismomax, you're running a turbo, right?
As far as I know, the Stillen supercharger mounts directly over the engine of the Z. So, without the Z IM and lots of retrofitting, it probably wouldn't work out.
The HKS is a centrifugal type. So, back to the same issue that we have with the Vortech kit. Where to mount it.

As far as performance, there's no doubt that a turbo will be better. But in order to properly do a turbo build for under $3,000, you need to piece your own kit together.
For simplicity sake, a supercharger would be much more practical. The general consensus is that people prefer a supercharger because it's "constant boost" rather than having to wait for a turbo to spool. Many people also consider superchargers safer. I'm not saying that this is true, but this is just what I hear people talking about at local car meets.
My power goals are more moderate, so a supercharger would be much better for me. I'm not looking for 400 wheel horsepower. I've just hit the point where the law of diminishing returns forbids me to spend any more money on trying to get more NA power.
And when you think about it, the potential customer base for this actually isn't that small at all. Think of all of the Altima SE-R guys who are looking for more power. This kit should be able to fit on any FWD 3.5 engine with very little modifications.
My friend has a Regal GS, and his supercharger has some sort of bypass valve that prevents it from building any boost unless you are above a certain throttle percentage. This is for MPG.
If someone were to make a kit that would allow us to use the Eaton superchargers off of the Grand Prix GTP or the Regal GS, this would be great because of the wide availability of those blowers.
Basically we need the pulley shaft extension, flanges and associated mounting hardware, and the piping. We probably wouldn't even need an inter-cooler if we only run a few lbs of boost.
As far as the times for that Altima, I believe he was having traction problems. I bet that som***** pull hard as hell from a roll.

I am running a turbo. I fit an old PFI turbo kit on my 5.5 gen. Took a good amount of cusom work to fit it, but between the kit and installation I have $3500 into the project, using all quality parts.
I talked to my buddy who owns the shop that I go to yesterday. He may have a couple places that can do a line balance on a pulley shaft. I'll just need to go talk to them now and see how willing they are to do it, and at what price.

My Altima has been on the giggly and is loving it, but then again I'm above the 320-350HP range by quite a bit.
Personally, I never see it happening, but I'll gladly eat my words if he pulls through. On a side note, somebody give me a shot of the engine bay while standing at the passenger headlight...I'd like to see just how much room is there to bolt on a centrfugal style SC. Thanks.
Thanks for the info. Looks like I still need to keep on reading.
That sort of info. makes a roots-type all the more enticing when comparing it to the centrifugal-type SC. As far as the gas mileage, I know I've heard of turbochargers ionizing air which in turn makes the engine burn fuel more efficiently, but never superchargers. But I guess considering both do the same thing, I don't see how it would make a difference.
No updates from this end. Although Wizard has a good point. I guess a good place to start would be making sure I can actually relocate and fit a roots-type in the engine bay.
I'd assume if someone can jam one in a 3.5 Altima that we should have plenty of space. But I guess you never know till you check.
Oh well...looks like it's time to hit the books some more for this kid.

Incorrect. SC's are not always under boost. And you're incorrect in saying that users will lose some of their gas mileage. SC's actually make the engine more efficient when just cruising/light throttle. Gas mileage actually stays the same, or increases slightly, assuming you drive like a grandma. If you put the pedal to the metal..well that's a different story.
As stated, this is only true for Centrifugal style blowers. Other types of SC's give almost full power right off the line (Twin Screw style), while the Roots style gives a good amount of power throughout the entire power band, but mainly the low and midrange.
Matty was/"is" developing a kit for the 3.5 guys....but after 3+years I'd say it will never come to fruition. I say "is" because he still says he's working on it till this day. Personally, I never see it happening, but I'll gladly eat my words if he pulls through.

So, another question/theory I sort of have, does DOHC vs OHV make a difference in power delivery when comparing centrifugal or roots type?
Also, here are some pics:
Never minds the torque link in this one, since that might make things more difficult.

The kit bolts to the LIM not the whole thing. So with a Z LIM this is possible. But it won't fit under the hood, and the TB will be in the wrong spot. ( Probably near the windshield washer reservoir) But with some creative piping and a funky looking hood it might actually work. Been thinking about this myself for a long time.
Now that I look at our engine bay, one thing I can see that could be a potential issue is the upper return hose for the radiator. But that goes without saying that it could always be re-arranged if need be.
I think with a battery relocation, a roots-type could be doable.

You'd need a huge hood cowl of some sort to get this to fit...unless you could somehow drop the engine low enough into the engine bay to clear. Which, AKAIK from reading, the ES motor mounts don't even drop it that far.

roots supercharger
ive been trying to put together a roots style supercharger for a while. I'm using a GTP gen V supercharger. I want it where its suppose to go right on top of the engine with a custom LIM it should make it low enough to clear the hood. Only thing I really got to change is the coolant hose location, so I can run the belt and tensioner.

Not a problem, just keep us updated as you can. I plan on trying something again myself, but I have a few installs (brakes, coilovers, n2o)to get out of the way first.
