Anybody heard HP #'s as well as the expected arrival date and price????

Life is to short to argue on the Internet!

yeah it will produce 350 rear wheel hourse power and be around 5 grand

 

yah I want to know too, any site you can link us to to find all this out?

Don't you think a TT will make more power than a SC? 350??

I think twin 18g turbo is crazy. i seen car with single Mitsubishi 18g produce 400 horses. If one were to add the number, it should be capable of doing 800. Off course to achieve this, major modification to the engine is require. I had the mitsubishi 16g turbo in my eclipse gst and it was running around 280-290 at the wheel.

okay....

1 turbo= 400hp, so 2=800??

3=1200?

 

Twin turbos over a single turbo isn't for more power. A single large turbo can give you more power than the engine block can handle.

Two smaller turbos will produce the same power, spool up faster, and have less "turbo lag."

The kit provides a mere 5.6psi, those units can provide more boost, but how much can the stock motor take is another story...

On another note a SC and turbo may provide the similar HP output, but a turbo will have a major gain in torque compared to a centrifugial type SC

<hr></blockquote>How do you figure that?
Granted that a turbo is not parasitic in the way a SC is, but the power drain is virtually insignificant when considering the benefits of a SC over a turbo (cooler air, no spooling lag). The net result is basically the same, given that boost levels are similar. Of course centrifugal units are different than "roots" type, or screw type superchargers (which have a more "positive" boost level), but in that respect, a centrifugal unit is going to perform in almost the exact same manner as a turbo - so I can't fathom how you can say a turbo would give higher levels of torque than a SC.

the reason that it is only making 350 RWHP is becuase once you get to around 10 psi on the G you will bend rods and such. so for warrenty issues and such they reduced the boost but the concept was also if the name of the car is the 350z why not give it 350 hp. Kinda dumb but thats whats thats all about. as far as a supercharger vrs. a turbo the benifit to a S/C is there is no lag but the down side is the S/C must use some of the power created by the engine to run the S/C. A turbo does not use any of the engines power but needs time to spool up. A turbo will also use less gas becuase it is only working in the higher RPMs while a S/C is running all the time. I personaly favor the Turbos.

There are kits avalible that will make the pistons and rods strong so u can run more boost. The G already has a comprestion of 101 which is really high if u want to run more boost you need to lower it. Thats what the kits will do. I personaly want to bore my G out .38 and drop sleves in so i can run crazy boost like 20 psi.

 

Carlos,

Are you crazy running 1.3 bar? Man i don't think you can run that high with 91 octane gas.

Yeah, that's the problem: the stock 10.5 to 1 compression. That's just not designed for forced induction. That's why the boost is set at only 5-6 psi. Any higher, and there will be detonation on 91 pump gas. The effective compression ratio is probably around 12.5:1 on full boost - just a guestimate - there's a formula to calculate the exact effective compression, but forgot it.

A motor designed for forced induction will run a compression ratio of around 8 or 9 to 1, and they can run considerably higher boost without detonation problems.

Conquie:

A turbo is free power, it does not take engine power to make it like a SC.

How does a centrifugial type SC differ from a turbo? they are the same beast with different methods of creating boost, but at low rpm, the SC isnt making a whole lot of boost if any at all since it runs off the motor. It too has some lag unless you are driving the heck out of it. As for cooler air, an intercooler takes care of that issue. As stated previously twin turbo's are usually smaller and therefore eliminate lag. Ever driven a 1.8T, no lag there, and that is a single turbo.

As for better TQ #'s check the links below, I own a SVT Contour and we have two kits available to us, one a Vortech SC unit that I own but have yet to finish installing on my project car. The other option is a Turbo kit from a company called Street Flight. The main problem with our cars is space, there is not much of it to put an intercooler and a TC/SC. The TC kit does have an option for I/C so far the TC's have better TQ #'s by atleast 40ft/lbs at the same levels of boost as the SC cars and have about 15-20 more hp. Even TC cars running less boost are getting better numbers then Vortech cars.

Here are a few links, first is a 2.5L SVT with SC with 10 PSI pulley

And here is a non-SVT 2.5L Turbo (SVT breathe better and gain more top end with fordced induction) at 8 PSI

Also the SVT 2.5L motor has a CR of 10.25:1 and its internals have held 9 and 10 PSI with out a major melt down (asside from one 3L motor, twice, while on the dyno to be tuned )

 

here is an interesting write up about the greddy kit

enjoy
alos i think the best kinda F/I would be electronicly spooled turbos like the ones on the new skyline (concept rumors). crazy stuff.

good luck
