I would rather be blown.... But Turbo's are cool too....

Supercharger, just wanted to be different. It depends on what you want from your car. On the real though, I would probably go with a fat ass turbo(you'll need all the torque you can get)

Greddy has a twin turbo 350Z. I would go that route; continue the heritage of the TT Z's.

a turbo or 2 sounds good for that car but i like superchargers more but ur car will be a nice ride :thup:

What kind of rpm's can it turn?
If it's a high rpm motor, go turbo. If it's low, go supercharger.

send it to japan and get signal to build it. they built a sweet ass fairlady. jk. arent the new skylines supposed to be using a tt version of the 350z motor?

One-third of the energy released during cumbustion goes into the cooling system, one-thrid goes down to the crankshaft, and one-third goes out the exhaust. USE THAT SHIT!!!!! Go turbo.

let em go blower

blowers will never make the power turbo does # for # the turbo rules and much easier on the motor

How much will you get from a turbo or supercharger with 10.5 compression? I thought they run better with 8 or 9 to 1 compression. I think N20 will work very well.

01-12-2003, 10:13 AM

10.5 compression is no big deal. Turbo all the way. besides it'll be a lot easier to fabricate a turbo for it than it would be to fab your own blower. I've actually got this little bug to get a 350Z. I dunno why. I look foward to seeing your results.

They look a little better in person that they did on pictures, I'll give the new Z's that. I still don't like them though, nice power and everything, just don't dig the style.

I think my next car is gonna be a 91 BMW 850i. Still checking those out; not sure if I really want one yet, but they look tight as a bitch.

Don't think I'll be able to afford my Porsche GT2 turbo for a while.

Yeah, I wanted a s4 last year but ended up getting an A4 Quattro 1.8T instead. Before I got the Z i was looking at getting a RS6 but didnt feel like waiting till summer. When I talk to audi there was already a waiting list. Get a Z..

its a v6..twinturbo..

excuse my ignorance, but im assuming since its a nissan motor, its not aluminum.. right? also how many liters is it? 3.5?

hm maybe single would be better.. 1.75 liters per turbo, couldnt be TOO big..

Thats not entirely true. Since a turbo is a big exhaust restriction it does rob a little power, but nothing compared to power a supercharger takes.

Redlines at 6600..The NOS should be in about 1 or 2 weeks. Depends on Mike at AUTO SOLUTION..RIGHT MIKE?

I did some research and as far as super chargers go, I would have to cut the hood or get G over at auto solutions to custom one for me. Both the turbo and the supercharger are under development. Greddy and Power Enterprise are the only companys that I have seen that have something in the works. Possibly nismo also may have something. So we shall see. Im sure Eric, Chris and Mike can figure something out before summer.

It's not actually "robbing" power. It's just holds the car in vaccum a little longer until the turbo spools up to positively pressurize the manifold.

Well that is partially true, but the turbo is still an exhaust restriction causing back pressure. Back pressure= power loss. The only way you could do it with no power loss at all would be to have the compressor powered by something completely separate from the engine: not belts, not exhaust.

01-12-2003, 10:46 PM

it is an exhaust restriction to a certain extent, but its kind of hard for me to say that, all its doing is spinning that wheel, and that shit is extremely easy to turn, shit, i could turn the turbine with my own breath, its not more of an exhaust restriction than your stock manifold, i do like the fact that a supercharger doesnt have to be cooled down and its pretty much maintenance free, but your just not going to get the power from a supercharger that you can from a turbo, but the torque numbers are pretty fucking dope.........

yeer

01-12-2003, 10:54 PM

greddy makes pretty good everything, so i would say go with their turbo.

but then again, im pretty happy with my supercharger.......something different. 10:5 compression isnt that bad, shit im running 5psi on my 10:6:1, ill probably be running a 8-10psi pulley when i decided to get hondata.

Mr.2

01-12-2003, 11:14 PM

The amount of restriction all depends on the turbo. The bigger the turbo, the less the restriction. It also has to do with the other characteristics of the turbo: ball bearing or not, a/r, trim, blah blah blah. You can turn some turbos with your breath, some you can barley turn with your finger. But none the less, the turbo does pose some exhaust restriction. It may be barley any at all, but it is there.

01-12-2003, 11:16 PM

Thats why you spray it too for the lag! :)

Mr.2

01-12-2003, 11:19 PM

That depends on the setup. Its possible to have a turbo with no noticable lag. But if ya wanna go slapping a T-88 on a 4 cylinder... yeah... spray that shit.

REDS TTYPE

01-13-2003, 01:09 AM

they do restrict pretty much but it dont take all that much power from the motor and you wont notice it cause the restriction goes up with boost so the more restiction you have the more power its making at that point so you cant tell

like on turbo buicks the factory tuurbo is small so you dont get lag but in return it gets 2# of backpressure for every # of boost

that ratio of exaust pressure to intake pressure causes it to spin the turbo up faster

as you get into higher output turbo's (bigger) the wheels are matched to give a better ratio of pressure from intake to exaust..

like say the wheels are set up at 1.5# back pressure to each # of boost... at that point you make more power at the same boost level only because you have less back pressure but in return less pressure on the exaust side causes it to spin up slower (lag)

once you get up into big race turbo's you can get down in the 1 to 1 ratio on back pressure to boost but thats where you get into high rpms before you get enough exaust to spin it fast enough to start making boost

hope somebody can understand that ...LOL

Mr.2

01-13-2003, 02:03 AM

Understood and agreed. My whole point has just been that turbos are not completley non-power robbing. People seem to think that they arnt, but they do a tiny tiny little bit. Not enough to make much difference, but they to.

Between your earlier statement and Reds "baffling" explanation :p (to most people it probably didn't make sense), I'll say that there's to many variables to make a correct statement about turbos.
Very small turbos have no backpressure at idle-low rpms but cause a restriction at high rpms. Big turbos are just the opposite, hard to turn at low rpms but flow ALOT better at high rpms.

I doubt that NISMO will be making turbochargers. I would get the PE's. But there's nothing wrong w/ Greddy either. I wonder if Pentroof has made manifolds for the Z33 yet!?! That's really the way to go! :thup:

I think I might have come up with a good way to think of it... it at least makes sense to me. Think of a revloving door compaired to just an open door. If you apply everything thats been said, and use people instead of exhaust gasses. It makes it easy to visualize.

I got most of my knowledge like that. I got the book because its supposed to be good. Id recomend reading it even if you do already know a lot. It helps to understand alot of little things, and gives you information about stuff you never thought about. BlahBlahBlah....
