we're not even taking into account that his buddy may not have a working supercharger set up on his truck? It's more than just power that breaks things it's people incorrectly modifying, rebuilding, working on things as well. Not applicable to this case but forced induction on an 70's era ford automatic c4 with vacuum kickdown will blow it up or at least make it not run right because the transmission decides engine load based manifold pressure and the c4 was never designed to see boost and lowered pressures around town so it would try to stay in low gear, shift funny, and just fail. With automatics you have to consider the engine and the transmission at the same time when modifying as a change on one without thinking about the other will hurt performance or break something. Look at what a valve body mod on a 350z does for it huge gains just by working with the brain of the transmission(well more like the circulatory or nervous system). If you have a manual you're straight because it's just a bunch of shafts, some gears, and a few levers hooked up to your hand and it doesn't give a fart about what you do to the engine (well unless you take the sensor ring off the flywheel for the synchro rev).

You do understand that /facepalm was toward your comment

You have never tracked your car therefore you have no room to talk. You do not know what it can handle at its limits in both the wet and dry... I have done both and I have spun the car off the track pushing the car to and beyond its limits in stock form. The Car will do just fine on the track in stock trim with only a few additions such as a oil cooler for the hotter climates and shorter tracks and brake fluid upgrade to dot 4 hi temp and finally steel braided brake lines for safety. The problems people have had with the calipers have been from running racing pads. These types of additions are recommended for any sports car that goes on the track. To say the 370z needs alot of work before it enters the track only goes to show your ignorance!

Also people like Semtex, RCZ, Mike, others and Myself push this car harder than you would ever get the chance to on the track... so the failures we see are from HARD use and I mean HARD! at Little Tally I dont brake until the #2 cone and I am full throttle to that point... I scare the ever loving $hit out of my passengers because I push the car so dam hard! My saying at the track when people ask me where are your braking points... I look at them and reply braking points? I dont brake until I see God!

Good day to you and please stop with all the FAIL you bring to threads!

This will decimate all after you put about $15,000 in it. Or more, if we have to overnight parts from Japan.

We'll put it on my tab at Harry's.

If you want to put a S/C on your Z, do it right. Watch your coolant levels, and head bolts/head gasket. Get a good cooler system, and put billet input and output shafts in your Automatic trans. If your a manual get a good double or triple disc clutch. Spinning faster you might need stronger push rods, better Cams, tighten up the blocks and balance it all out. Its a long process not just, Hey lets throw a SC on the car/truck and watch me run 10s... etc.

I know a little bit about the Supercharged Titans in general. Stillen made a good kit but it has some tuning issues and will not change the kit to fix the "known and well documented" tuning issues it has. I'm not bashing Stillen by any means, but their supercharger for the Titan needs to be offered as a hardware only kit and let the end user decide on how to control fuel and timing.

2 things automatic Nissan/Infiniti vehicles care about.
#1 Obviously being power/torque.
#2 is a little thing called Calculated load. The ECU determines what the calcualted load is and sends that info to the TCM which in then tells the transmission what to do. If the TCM sees 35% load it's gonna shift nice and soft but once it sees 100% load it will make the line pressure adjustments and move the shift points around to accomodate the increased load on the engine.

Lets go back to #1 - Power/Torque The Titan uses a slightly beefier version of the RE5R05A automatic transmission which is the same trans used in the M45/35 G35 350Z Fronteir Xterra Q45. Its a workhorse transmission. The titan, if anyone knows, has a boatload of torque - stock it puts out 385tq. I've seen modded Titans putting down over 450rwtq numbers without the supercharger. With the supercharger the torque literally goes through the roof and the biggest gain is in the lower revs.

Now lets combine #1 and #2 and you can see that now if the ECU sees less than 100% load but in reality the truck is making 200% more torque then failure becomes an obvious reaction to the Stillen supercharger.

In all fairness to Stillen - Their kit just needs to be switched from a piggyback ignition controller and extra injectors to a system that can program the ECU like UpRev or COBB and be calibrated for larger injectors. Also it should be mandatory that at a minimum a transmission VB upgrade be included or strongly recomended.

How does that apply to the 370Z - well if you are a 6MT then mod away - change the clutch to a beefier one that has the torque rating slightly exceeding what you will be outputting and also change the transmission fluid to a nice synthetic (redline, RP, Amsoil, etc...) to help with the extra load. Also heat is what kills to add and engine cooler/diff cooler/transmission cooler even for the 6MT peeps. One thing we cannot get away from is rated torque capacity of the transmission itself. Nissan has notoriously installed beefy components in that regaurds at least for the MT cars in the past so not even looking into it I would assume the 370Z trans to be about the same if not better.

If you are a 7sp Auto - then you will be breaking new ground. Expect failures of the transmission. My recomendation is to look at the guys running Nitrous(if there are any) and see what they are facing. Maybe even buy a Nitrous kit first and do some data logs and see what's happening before you take a $5-6,000 plunge for FI.

Any street car can be made to track - and if you got the 370Z specifically for racing then Awesome - if not - then awesome too. We're all Z car guys/gals and we enjoy what the car can offer. I can honestly say that there is a car out there that is better suited for track duty than a 370Z and there is also another car out there that is better suited for daily driving. But that's not why we have them, it's because we think they are awesome, beautiful, masterful, sleek, enjoyable, fast, comfortable, hot, sexy, cool, hip, nostalgic, new, high tech, etc, etc, etc.....

Lets have fun with the 370Z - cause I won't have one for a while and I'm envious of you - but I can say that I have the 4 door version of the 370Z (M45) and it's just as great in my mind. can I get a Hell Yeah? HELL YEAH!

Kyle very true! and thank you for your added points to the subject. I have seen supercharged and turbocharged s2000's on the track and i must say they are scary fast!!! Non of the cars had any problems period. The supercharged s2000 only had a clutch and flywheel installed along with coilovers and 18" wheels with race compounds. The car is owned by a local honda shop owner and at 9.5psi he is putting down 400hp!!! he kept his high compression gaskets and the car runs flawlessly. JoeD to quote your agreement with another persons post
" 'This is just me, and I know I'm on the wrong part of the forum to say it, but I think the S/C is just going to cause issues in the long term. On the track, it means you need a full BBK, the transmission may have issues, the differential will definitely need a swap or a serious cooler, and engine cooling may be an issue again. That means the S/C really costs $10K+ if you want to use it (traffic light drags are obviously another issue)'
All these issues which you mention need to be addressed before even a stock Z rolls onto a track."

So your telling me I need BBK, my tranny is going to have issues, I need to swap my diff and add a cooler among other things before my stock Z rolls onto the track?!?! cause that is word for word what you said and agreed to and that my friend is what i am arguing.

As a word of advice take the time to read your post before posting it. You have not taken that time on any of your posts in this forum and it is quite obvious because you are always having to defend yourself. I can understand many of these upgrade for going F/I but that is obvious on any NA car going FI... once you strap that extra power you are pushing the components passed their rated performance levels.

Again, I STRESS to you to READ your POSTS before POSTING! You already have a reputation on this board for ignorance and trolling and that is not my opinion that is a commonly shared belief by the majority of members here soooo if you want to save face and not get hostile responses. READ your POST before POSTING.

Thank you and good day

Well...yes. I don't see the argument here. We already know the factory Akebono Sport-package brakes are not up to the task. The transmission itself is just fine, but issues with the factory LSD over-heating and not functioning properly have also been reported.

Again, I have no clue what you are bickering about. Perhaps I can quote Stillen from a recent post to provide you with some more insight on the car's brakes...

bullitt5897

Like I said earlier I have pushed the car and so have others and the front calipers are fine when you are not using overly aggressive or out of balanced race compound pads! all of those things have been stated in the other threads as well. Factory LSD over heating nope I havent seen that one nor experienced it. Mine worked and still works just fine.

JoeD have you ever heard of Marketing? who is pushing those products? hmmm would it be stillen? *nothing against stillen the company or Steve Millen* but that is a form of marketing this is better than stock and if you want better performance you need to buy this or that... Have the Sport calipers failed using regular pads or not overly aggressive or out of balanced pads?.... the answer is no! Again I have yet to see any true problems with the rear diff! could a cooler help yea it could but what sports car couldnt use a rear diff cooler?

My point is: is that you often talk out your butt without thinking! and the fact that you agreed and implied that major changes need to be made before a stock car even rolls out on the track! thats my point and its not bickering its called pointing out your fallacies... Could those mods help yes and i am not arguing that. what my argument is is that they arent a necessity to track your car at what ever level. If you want to be more competitive yes changes will have to be made but it is not a requirement due to badly designed parts proned to fairly like you so easily allude to.

Superchargers have a much higer failure rate than turbochargers due to the inherent design of adding more moving parts - ie belts, pullies, brackets, idlers, tentioners. Also the supercharger itself has it's own self enclosed bearings and gears that introduce new failure points as well. Failure of the supercharger "normally" doesn't meant the engine goes boom.

Turbochargers have 1 added moving part - the turbine and compressor blades that share a common shaft - technically if you have the ceramic ball bearing option you can include that but it has been proven to be nearly bulletproof even when you include oil starvation. If you include the Wastegate and blowoff valve then techically that is 4 moving parts added to the engine. "Normally" a failure with the turbocharger makes the engine go boom.

Technically Kyle - superchargers are more prone to failure unless they are engineered correctly and installed with prowess. Mercedes and Ford have it down pat. Jackson Racing did well with the honda stuff but there were induced failures that did occure due to engineering mistakes. ATI - I've seen bracket problems, same with Vortech, do you need a cogged belt or will a serpentine do just fine type of problems with superchargers. I have even seen bearing failures on pto shafts for your superchager on the titan - which is not the engineer's fault, but it does happen.

Most Failures with a turbo are blown boots on the intake piping which causes relatively no harm. If it is tune related or wastegate failure - then you have a blown up engine. Rare failures are compressor blade breaking being ingested by the engine.

Most failures with a supercharger are belt noise, belt breaks, broken pullies, bearing noise, rare occasion is FOD (foreign object damage) to the pistons and valves, Leaking air to water intercooler causing excessive smoke and or hydrolock on startup.

I think Kyles post refering to reliability is to the point that superchargers "normally" don't blow an engine when they fail and that turbochargers do. You can't get boost greed on a supercharger like you can on a turbo. It is very easy to pop an engine on a turbo car UNLESS you are very responsible with that boost controller - lol

Or the fact the the EXTREMELY high heat inherent in turbocharger systems cooks the bearings and cause metal fatigue and burn-off and turbocharger units typically are considered needing replacement between 50 and 100,000 miles on STOCK turbocharged cars and much sooner as soon as the rpm of the turbocharger unit is operated out of the manufacturers suggested range. They also have oil seal problems over time as the seals age from the heat and typically burn more oil and smoke more than supercharged cars. Whenever you deal with modification though there are always going to be people that do things incorectly and abuse the car and the parts for both superchargers and turbochargers and failures will happen.
