What up im going to put in a new clutch kit soon ( ACT NM1-XTSS) It's a street disc with a Xtrem Pressure plate. I was looking at the Fidanza 12 -13 pd flywheel. My question is should i change my flywheel also ? Am i going to gain hp or tq if i get this ? Does it work great with N/A or supercharged Maximas ? All i need to know is the pros and cons. So anybody with info or who has or had this setup who share this would be greats. Im N/A now but deciding 50/50 to do a V2 charger.

 

You wont gain hp per say but it will rev faster. I am running the Fidanza in my turbo car and it revs like crazy. It would help a s/c car more than turbo but after second you wont notice its there.

 

so it not worth the $300 to do it? I found the flywheel at this ebay link

http://cgi.ebay.com/ebaymotors/Fidan...spagenameZWD1V

ALSO IS THIS TRUE I FOUND IT IN THE LINK

 

Yes. It is a bit tricky to get used to rev matchin, but you'll catch on fine. I would definetly recommend. I loved it when I was N/A and its nuts with forced induction.

I dont understand how it allows the engine to rev faster yet doesnt free up horsepower. Can someone explain that to me? If you lightened your internals on a motor wouldnt you gain horsepower from doing so? its less load on the motor.

I'm considering a flywheel as well...not sure on what brand but...it seems like a worthwhile mod.

 

OMG here we go again. a lighter flywheel doesnt give your engine more power! It helps by allowing you to put more of the ponies you already have to the wheels. more hp to the engine = no, more hp to the wheels= yes. get it?

 

what does it matter, more horsepower is more horsepower...but to say it gives you no power gains yet allows you to rev faster just sounds a little contradictory to me.

 

It would still work great for a N/A motor for now right? I get what you saying about more hp to the wheels. Thanks

 

ok chillin014. put a flywheel its going to give you 100hp more. and yea nyc its still good for a n/a and then you wont need to worry bout it if you go with the V2

 

alrighty thanks

 

Are you just here to discourage others with your invalid "its horsepower, but not REAL horsepower" statements?

I'm the last person to invest in pointless mods without doing my research, but this is plain and simple physics..less rotational mass on the end of the crank= less load for the motor to turn over. How much? I'm going to search around and see if I can find an answer.

edit- I've found a pretty informative site...should explain all.
http://www.uucmotorwerks.com/flywhee...heel_works.htm

its pretty interesting how it works. The horsepower gains in lower gears according to that website are pretty healthy. I wish it was the opposite however because I've got enough traction problems in first.

 

wait so a flywheel is a waste of my money ?

 

search and ask around... it doesnt add HP to your engine but it does give you more HP at the wheels! Whats so invalid about that? and who said its not real HP? I just said that it didnt produce more HP but it let you put more on the ground! Wow! Who am i discouraging? nyc96max understood perfectly what i meant!

 

Cant we all just get along ? That link explained what i needed to know If that is incorrect can somebody confirm that or is there another link we can see ? Thank you both for your answers. (arrocha87 and chillin014)

 

that site explains it pretty much how it is. same as i said, alot more words. and im sorry i get agitated chillin, i just had this same argument with some ppl that where nosying around my my friends house where we are building his 91 5.0 stang.

 

What mods do you have?

 

your such a lame ***! your always on this website and never want to spend time with me!!! now im gona come on here and see whats so cool about your car

p.s how about u fix your a.c!

 

i have it and my car revs faster and i dont have a turbo and supercharger and feel the diffrence. good mod

 

Yes i say get it. I love mine.

 

A lighter flywheel does not add power. It allows the engine to rev faster, due to less dead weight that the engine must over come. It frees up power. Yes you will make more power, but it doesnt add power so to speak.

I have a fidanza and i love it. Getting use to rev matching as previously stated takes a bit of getting use to, but its something you'll live with.

The thing with the lightweight flywheels, is its not an easy mod to install for most people, and they are kinda pricey. Case in point, look at all the maximas with intakes, if the flywheel was easy to do, more people would do it.

IMO id get it, if you have the money. Also look into replacing your rear main/oil pan half moon while your down there if its leaking!

 

OP, search some of my posts, I've gone really in depth about this and don't wanna re-type it all. Basically, if you decide to replace it, do it the right way by pulling the upper oil pan or don't do it. Usually, even if it's wet you won't need to, it has to be BAD to find it's way to the clutch.


All you have to do is push one pedal and release another and it's pretty much guaranteed to put out, and at the same time make cool sounds that you know aren't fake.

It might ask for a new starter but not a diamond ring.

Even if you find out it's beat up and been around the block, you can just trade it in for a better one.

Getting it to drop a few pounds and a few tenths is just an afternoon project.

It doesn't get mad if you don't spend time with it.

 

NICE! or how about, it doesnt wake you up with a drunk phone call at 2 AM.

performance wise-3.5 swap with bolt-ons./complimenting mods/a/f tune

 

I have one N/A and I love it! Revs sooo much faster. I think the stock flywheel weighs around 26 lbs, so there is a HUGE difference in weight savings. And yes, it doesn't add power to the engine, it just knocks a bit off of the drivetrain loss.

 

Rated engine torque and horsepower are tested under load to minimize inertial effects. It slows down the acceleration of the engine so that you don't see flywheel effects of the flywheel and drivetrain.

Of course on the road it's very apparent, just like switching from light 15" wheels to heavy 20" wheels.

Now back to the OT: there is one caution I'd like to toss out there: the clutch is the cushion between your engine and the road. If you get an excessively stiff clutch for your needs (e.g. extreme pressure plate on an N/A car), take care not to dump the clutch hard and shatter something inside your transmission. Less stiff clutches will not shock the driveline as hard if you don't launch cleanly.

right, that makes sense. thanks. I guess the dyno doesnt tell all!

 

Do anybody have a pic of the half moon he speaks of? I want to fix my car right.

 

Yes i am very aware of the pressure plate and tranny issue that you speak of.

 

I was gonna say the same thing. Stock flywheel acts like a buffer making for smoother left-footwork. But I liked having the fidanza, I could shift faster (not having to wait for the fly to wind down revs), and my downshifts (I double clutch) were much smoother and quicker. I don't heal-toe, but I guess it would make it easier? Throttle response was hugely improved.

I understand the pros and cons of a lightweight flywheel and i plan on getting one, along with a new clutch (exactly which clutch i still don't know suggestions would be great) but i was recently of fidanza's website and its flywheel applications were list 96-00 maximas.. i have a 95 and it should be included, right? any input would be great. forgive me for posting on more dead threads

 

There's been some debate on that, but I've got an early build '95 and have had no problems with newer flywheels. Personally I think it's another one of those myths, such as the '95 being OBD-I.

 

i got a 95 with findanza, and it works....diffrence? well i get wheel spin in 1st all the time now....would i do it again? sure if i had the money.

it is kinda pricey

 

Less rotational mass = frees up hp and ups MPG? Might take a while for those increased MPG to make up the high cost of flywheel.

 

wrong, gas mileage will decrease. Less rotational mass means less momentum to keep the motor turning at a given rpm. Maybe less gas used during acceleration but during cruising it would, in theory, be worse on your gas mileage. Probably not noticeable.

 

Gas mileage, im not so worried about. I should be, but if i was, i wouldn't be lookin to dump more money into my car just for fun. Pmohr, you said something about 95s being obd-I and for some reason i havent heard of that term.. 1. could you explain to me what that is, if its even important? 2. those with a lwfw, are the gains noticeable? (don't get into hp on a dyno i understand lwfws dont technically give you more power) thanks again for the input

 

all 4th gens are OBD2..its just the diagnostic system for the vehicle. It has nothing to do with flywheels. Gas mileage shouldn't really be effected. Cant comment on the gains...but the reason it doesnt show up on a dyno is because by 4th gear there are really no gains. You feel it in first and second mostly, apparently.

 

Yea, it has nothing to do with the flywheel, I was just mentioning it as another '95 specific 'problem' that people mention that's not true (as far as I've seen with the flywheels, anyway).

I've driven one VQ30 with a light weight flywheel, but it was also turbo and had an extremely aggressive clutch, never really got on it either (came into the shop for an EMS install). Just driving it into and around the shop, I didn't notice any difference with normal driving, but I'm sure it really helps during heavy acceleration. That's my experience with the A33B and pretty much every other car (Z33, mostly).

 

Oh I understood it. your confusin' the noobs though!

I'd be interested in a 6 speed swap for my vq35 but I know those flywheels are a good bit heavier stock so I'd have to get a lightweight one just to break even .

 

Yea, the stock dual mass flywheels are heavy as hell.

 

> 30 lbs.


And good luck finding an OEM'er with no hot-spotting. I'm just gonna spring for an aftermarket unit. Win on 2 levels.

 

I have been using an RPS stage3 clutch(sprung) + Fidenza FW for past few yrs. not on the maxi but on the supra(single turbo etc.), dont expect HP gains but it does help on Revs, not so much that i was blown away but noticeable

Good thing about LW FW is that you'll save weight = less rotating mass = a little bit faster revs

Best bang for the buck i did to greatly improve throttle response was using a 90mm Q45 TB but again not on the max.


ps - always remember to change your throw out bearing, pilot bearing, flywheel bolts, & snap ring every time you change your clutch. Good Luck
