thinking of a turbo setup

edub370 · 03-27-2012, 01:52 PM

TBH tho, for the minimal boost that most people run on these cars (anywhere from 7-10psi most of the time) a larger turbo isn't needed because 600whp is the danger zone for these engines. seems almost like a smaller turbo would serve a better purpose for the boost that we are running, no?

R&D on my end (on the VQ) shows that you need a T4 .81 for about 600whp (DJ) on pump, and .96 a/r if you wish to push things past that. (.58 T4 = .7x T3)

I find it very funny when a manufacturer says "600hp" turbo. That is great, but it is only the rating of the compressor wheel, and not the turbine. So you have a large compressor that will flow 65lbs/min of air, but you have a turbine housing that can only flow 50lbs/min....and THAT limits you to about 500hp. So you can have a turbo (compressor) that is rated to 1000hp, but if the turbine stays the same, all you will get out of it is 500hp.

Fluid dynamics will never cheat you, but somebody selling something will.

Or maybe its a .67 now that you mention it idk ,
They told me I coulda got the bigger turbine housing cause of my sea level but I just left it , looking forward to see what your kit does

I agree

This is true to a degree. Once people start building the engines, this becomes a problem. Now you have to use a large turbine for the added flow, but you will lose a lot of spool with a kit that places the turbo far from the engine. Also, these engines are not made to be torque monsters, so low RPM boost does not play a big role. This is a high revving V6 and it makes its power at 4500rpm+.

I will have 4 turbine options, so it will cover everything from a stock block to a fully built one.

No such thing, it must be a T4 .68 then.

Ours is ready right now and has been proven over the last 3 years around the world.

I would love the get the Twin kit but my wife would be cutting off my twins

because of the price tag. Im look for the single turbo alternative due to price. Can a single turbo like an STS kit be able to have the same HP and proformance and a twin turbo kit?

I can empathize with that sentiment. haha

The answer to your horsepower question is yes...they can make the same power...so do our supercharger kits.

The key is "performance". On this platform, a supercharger kit, a single turbo kit, and a twin turbo kit will all perform differently, in a "Good", "Better", "Best" sort of way. Sure, they all make boost and more or less the same horsepower on a stock engine. The real difference is how they deliver the power, and in terms of area under the curve, it is tough to beat the twin turbo systems on this platform.

Not really

:

Dynosty Nissan 350Z custom single turbo vs. Forged Performance Nissan GTR E85 - YouTube

Power under the curve, I would say this is solid and comparable to a twin kit (twin scroll kit on a stock block 04 350z, on 9psi).

As for what is good, better, best...it all depends on the driver, and what the car is being used for.

Not trying to ster things up...just saying.

I don't think there's anything wrong with having two companies competing in the same market "fight" for customers. Just my :two cents:. Either way when I'm ready, I'm going with GTM since they are only about 15 minutes from me.
