supercharger on an 03 Z
i've only heard of vortech's spinning crank bearings or cracking pistons and all those cases were abuse/bad tunes, often when the owner knew he was running really lean, but ran it hard anyway or previously often ran beyond redline or heavy nitrous shots before putting the vortech on.
Even in the cases where the engine was damaged while the vortech was on, the engine was drivable. It either was just down on power and/or maybe blew some smoke out the exhaust when running
I've read just about every thread on all major Z/G forums for the vortech and I'd really like to know of ANY fatal engine failures with the vortech because I haven't heard of any. And race teams don't count - they blow up stuff all the time.
I remember reading various threads about blown up stillen engines though where the engine was completely done. There's been at least a handful
BTW, if you get the right mods with the vortech you can have more power/tq than the stillen kit from 3300 rpms and upward than the most powerful stillen dyno I've ever seen. If you change to shorter gearing it'll be even a little easier to hang in higher rpms. And just like the stillen, there's a direct linear relationship with the throttle and response
turbo is a good option though too if it suits you

id say the Vortech has a more linear power line due to yu gaining boost over the rv range (e.g 3000 rpms=3psi boost- 5000 rpm= 5psi boost, i know this isnt exact but you get my point vs the stillen using the rotex style where it boosts differently..
BOOGER.. i always thought you could run a lightned flywheel so long as you stay away from underdriving.. how/why is this?? i would love to know, ive been wrong for some time if you are right.. lol Thanks..

VERY Helpful. Thanks Sentry!

underdrive pulleys have a smaller diameter. they UNDER DRIVE accesories to free up power. They are normally lightweight because of what theyre made from. One manufacturer of a underdrive pulley for the z is UR : unorthodox racing.
Lightwieght pulleys have the stock diameter and are just made from lighter materials. KJR makes a lightweight crank pulley.

I'm currently running a lighter, but same diameter crank pulley - KJR, but I'm sure I'm on borrowed time before it takes a crap on me since it doesn't have a steel sleeve.
I would stay away from KJR. If you're going to think about going lighter, get the same diameter UR pulley because it has a steel sleeve.
I got my KJR pulley back when they first came out before people knew about their problems. So far mine has held up for 7000 miles and was installed properly while the engine out of the car so you could really see it going on. Someday when I build my engine with the GTM stroker kit, I'll probably go with the fludamper pulley which is actually a hair heavier. But I don't know yet...I might still consider the UR. It'll depend on what Sam@GTM thinks. I'm not going to run the engine beyond 6700 rpms
Procharger is good too, maybe a little harder to come by and work with though. Very few people are making more than 400whp with them for various reasons - usually belts snapping

AAAHHhhhhhhh o.k i get it.. thanks guys, i knew not to use my UR underdriven one but was told that i could and should use a light weight one in its place.. clearly a little unreliable info.. ill have to look into this..
*edit* wait so its mainly that they didnt have a steel sleeve?? i know the UR ones do.. guess i have some more researching to do..

1) there are no real gains to a stillen Supercharger.. its maybe 10 to 20 whp over bolt on's
2) i have proved in another thread that Vortech is more reliable than Stillen
3) Turbo's don't blow your motors.. bad tunes and bad installs do.. this isn't 2005 .. Turbo setups are as reliable as SC setups.
4) Built Motors still blow as do Stock Motors.

Assuming both are tuned & installed properly, do you really think you're going to get the same reliability on a turbo as you would on an SC?
To the OP, if you wan't an SC, I would definately go with the Vortech.

I'm all over the blown up vortech engines like flies on **** and haven't ever read about or heard about a single fatal engine being blown up with a vortech that was due to the vortech. About a year ago I read every single past thread involving the word vortech here and on G35driver because I wanted to know what it took to really kill an engine with the vortech or what the limits were
I'd like someone to PM me the second they hear about a fatal engine with a vortech. I have a feeling when the day comes, it'll be a pretty big thread with lots of people in it because it will actually be kinda a big deal - the first public knowledge about a fatally blown engine that was running a vortech
To my knowledge, there's been maybe 5-7, maybe 8?? damaged engines with the vortech and they were all due to abuse, bad lean tune, or ignorance (no gauges, no tune, breathing mods but using the stock tune with no idea what's going on

On a side not, 20,000 FI miles must be a blast
