Supercharger and/or twin Turbo for FX37 engine

I know of an Infiniti dealership that installed a Stillen s/c, so not all are like that.
 
I believe if a dealer installs a Stillen SC for the 370Z or G37, the factory warranty remains in place. But for me at least I would never trust a Stillen SC again even if the dealer warrantied it. Since the kit isn't for the FX, it doesn't matter since any mods required to make it fit would probably cancel the warranty.

There isn't. Infiniti dealers are scared when I bring my car in. And it only has coilovers, exhaust, and some electronics. I literally had one try to deny warranty becuase I had factory DVD headrests. He was SURE they were aftermarket and even made me turn them on and show them the Infiniti logo. Morons. They would NEVER sell something performance oriented like forced induction, like Toyota or Honda will, unfortunately. They just dont have the market.

Did they warranty it?!? How much was it? That is astounding, I'm very interested. We must have some pretty crappy dealers around the DC area if so.

Around here they would certainly install anything you want (at $125/hr) but on a 2013 FX37 they would deny every warranty claim and make you fight for it.

Other than the examples in the posts above, Infiniti has recently created a performance line a la TRD and HPD. It even has a sweet TLA - "IPD". Further, the next generation of Infinitis has been confirmed to include forced induction.
 
Never heard of IPD. I think you're maybe referring to "IPL"? I'm well aware of them, they make exhausts and body kits.

But I think we're talking about two different things here, aftermarket add-on performance parts developed and rebranded by OEMs vs Factory models with forced induction.

TRD is Toyotas line and has been selling TRD developed and branded superchargers since they 1980s. They are ADD-ON accessories. Of course infiniti will produce forced induction models, all manufacturers must comply with the emissions standards required by 2025 and to do that you have to decrease displacement or supplement with EVs. Turbos are the cheapest way to do that.

I wouldn't hold your breath for an Infiniti branded or IPL branded supercharger though. Although it is refreshing that a couple dealers are installing Stillen SCs - even if they kinda suck lol. TRD aren't much to write home about but they are more efficient.

justin I can't multiquote format this whole post but this a quote from you:

"I agree with everything you said, except for the cast manifold. In practice it is not a restriction or inefficiency until WELL north of 500whp..."

thanks for that link to the supra forum thread, I've read that before, but even that thread confirms that a cast log is indeed an inefficiency even under 500hp. it affects throttle response and spool time across the board. a cast log is a compromise and a trade off and is mainly used because it is cheaper and easier to mass produce. I too didn't suggest anyone runs out and builds a $3,000 set of custom equal length tubular manifolds but that really doesn't change any of these facts. from that very thread, right on the first page:

___________________________________________________________________________________________________--
"a cast manifold is "typically" more durable, however, the cast manifolds simply cannot outflow a tubular manifold. also the cost of cast is far more affordable. the other, and more argued side of this is how inefficient the log design is due to the fact that the exhaust pulses leaving the engine slam into each other in a log setup which causes several things, among them including added heat. also, contrary to popular belief, spool is usually improved with an equal length manifold rather than a log type due to improved exhaust scavenging. to me, the very few negatives of a tubular, which, i would only buy equal length, its the price and the fact that they are a bit more susceptible to cracking, mostly around welds and/or WG flange. HOWEVER, much of this is due to poor bracing, as well as the quality of the material and welds. there is so much to learn about these and even more opinions, just do your research and make a wise decision."

also just to set the record straight here, in your post there you imply I'm driven by some sort of gang mentality and say I was name calling and that even I called you a dick, but that is not accurate. I did not call you a dick, I said you were acting like a dick. there is a difference. I won't go any further with that whole mess, it would really be pointless.

I guess two people can read the same peice of information and extrapolate two different conclusions, depending on what they are predisposed to look for. I see these quotes from that same first page:

I had a PHR Stg1 on a modified Turbonetics cast manifold and thought it was perfect for what I wanted...fast spool, durable setup capable of 470whp at 17 psi on pump and a tad over 600whp on racegas at high boost. As far as why the majority uses tubular, a lot of people here are making power levels that exceed what the logs are good at.

I made 816rwhp with Arnout's manifold and a PT70GTS. HKS 264 cams, everything else on the motor is stock down to the intake manifold and throttle body.
Everybody always wants to claim the cast manifolds are just the cheap way to do things and that they suck for power, but I feel that if you have the other necessary mods the power can be very similar to a tubular header.

Cast is cheaper typically, more reliable, usually provide at least couple hundred rpm worth of honest spool improvement better fitment in a lot of cases as well.
Con cast:
never equal flow, nor equal resonance tuning. Flow is more restrictive, doesn't sound as nice usually (preference obvz)

Tubular would be the opposite of the cast.

i have to search for it but mr corky bell himself once said that log manifolds are king but an equal length tubular header provides better response.

my cast manifold, it fits great and performs very well....My 67 spooled faster than other friends with 61mm turbochargers, on virtually the same setup as me minus the manifold.

i also want to add that while certain log designs MIGHT produce a slightly quicker spool on certain setups, that of 300 rpm or so is certainly not worth the loss of efficiency at higher rpms

I was just asking if anybody can show a real example of a tubular outspooling a cast setup at the power levels I mentioned...I've never seen that happen.

theory is nice but its the real world that counts ;-). Never seen a tubular mani. spool faster than a log mani.

As I have seen in your previous posts, you at least seem logical, so I think you would have to agree that the point is "arguable" to say the least. One random person off the internet's opinion quoted from a page of opinions does not make it truth.

I speak from my own personal experiences in our shop. Our shop makes and sells tubular manifolds. One nice thing is that since our engines are STRAIGHT 6's and 4's our tubular manifolds are 1/2-2/3 the cost of a V arrangement. Therefore it is much cheaper for me to upgrade to tubular.

But I don't. Why?

Because I have free access to a dyno and see the outputs from shop and customer cars on an ongoing basis. At 400whp (where I CHOOSE to be, I dont like higher hp street cars for a multitude of reasons I wont get into, but the most of which is reliability) a tubular manifold will not increase my power enough to justify the cost (only about $350 for me) and the unreliable nature of tubular manifolds (they crack 1,000,000% more often than cast manifolds, even with high quality welds and proper bracing - I dont think I've ever seen a log "crack")

As for me acting like a dick, you're entitled to your own opinion. I'm too old to care what unaccountable words on the internet "think of my personality". Those who meet me in person (We host car meets and have probably met over 5,000 people off internet forums) don't think I'm a dick. So take a step back and consider the fact that maybe I just hate politics, don't care what you think of me, and speak truth without worrying about feelings. Sorry, I'm an engineer. If you want to talk about feelings and make friends the real world is right out that front door -----------> ;)

What does Invasive Pneumococcal Disease have to do with superchargers? Stop trying to bait me into an argument, its really transparent and sad. Don't you have anything better to do with your time? If you want to talk about cars or technology, I'll debate all day long. If you just want to talk trash, piss off :)

FYI, MOD-ER-ATORS, THIS ^^^^ IS THE TYPE OF POST YOU SHOULD BE MOD-ER-ATING. Not fanning the flames as you've [EDIT; LOGAN, obviously, the other mods don't engage in that crap that I've seen] already demonstrated you're apt to.

It was a rhetorical question. Obviously the two are not related. One is an educational accomplishment and the other is a personality disorder.

There are plenty of engineers here with intact social skills. That was my point. If you want to be abrasive and insulting, just do it and own it. Hiding your temper behind your job title is what's transparent and sad.
 
The kind that are dicks; obviously ;)

I've never even posted what my job title is on this message board. Chuck just has an overactive imagination. Much like pdizzleandbeans, I work for a very large corporation and my job has about 5% to do with engineering, and about 90% to do with project and personnel management. Yes I have a mech engineering degree, yes I manage people and take my job seriously, and yes I don't care if asserting myself in the face of grossly inaccurate e-pinions "makes me look like a dick". Its an internet car forum, its all make believe. Its like your Microsoft Word program calling you names. Its comical, and indicitive of the culture that some members try to build here. I'm not falling for it, if you dont want to listen to me, ignore my posts, if you dont like my opinions, don't ask for them, and if you dont like arguing with a "dick", then stop starting arguments. [not directed at anybody in this thread, except the trouble makers and instigators. Hope everybody realizes that, I've been on here plenty and get along with 90% of you guys, just a few guys follow me around and try to argue cough.Chuck.cough)

Seems pretty straightforward to me.
 
I think this thread has moved way far left from the op's original question. Please direct any further communications with each other through pm or use the ignore feature.
