G35c turbo- Which is better and why Twins or Single and what type of set-up

[dkrep]

So the real question is what setup works the best.

Twins Single- Large trimSingle Small TrimRear Mounted-Or Twins Small and big.

and what turbos run the best with the G35c

[joe603]

Twins are the way to go! The size depends upon your HP goals and the application (drag/road course)

The only thing about the rear mounted sts turbo is that they a 1 1/4 or so charge pipe through your rocker panels all the way to the front of the car. have you seen or heard about these at all. the only thing i think that is bad about them is that they are not as efficent with boost as a normal turbo and they require a seprate oil pump which comes with there kit.

[tollboothwilley]

as its true you lose about 1psi through the piping being extra long, the efficiency is still higher because the longer piping allows for extra cooling.

Its a trade off really, but in the end works really well.

There is a guy here in utah that is putting this STS turbo on his sedan...

I'll let you know about the dyno results.

Supposed to reduce the turbo lag though, since its channeled so far back in the exhaust.

All i can say is sex.

[dkrep]

right but all i can say about them is i am sceptical about them. i have seen it in person on a 07 vette twin set up. it put 652 to the wheels with meth injection. so i guess it has its pros an cons. my boy is also putting one on a Mazda Rx8 so i will post numbers from that as well.

The pressure loss wouldn't be the worst about that kind of set up, the really bad thing is you will have some insane turbo-lag with that kind of setup.

On a V engine you'll typically have an easier time to plumb two turbos. Don't have to worry about joining the two exhaust banks somewhere close to the engine etc.

A single turbo is typically a much simpler and less expensive setup. But, with the added modifications needed for a V engine that benefit can easily be lost.

As far as power and spool-up time and that kind of stuff goes it really doesn't matter if you have a single or dual turbos, all that matters there is the specs of the turbo(s).

[tollboothwilley]

Actually, turbo lag is minimized in this setup

[gwoods]

STS is a great turbo system.. very little lag.

The only downside is your air intake is now UNDER the car. It gets dirty and can suck water.

Wouldn't be too hard to peice together you own single turbo system.

[TeflonG35]

If lag was an issue you could always get a nitrous system to cover the lag gap.

We've had several discussions about STS turbos in the past. As such, instead of typing out a huge post, I'll just link to one of them.

I talked to sts today and they said the 350z/g35 kit is a pain to install on a sedan( ), but gave me the number to a shop around here who has installed them before.

[dkrep]

like i have said earlier about the sts rear mount turbo is that the is little to no lag lost but you have to buy a seperate oil pump. there is a guy that i talked to this weekend who is the first guy to put one of these on a corvette hence the 652 twin setup that i got to see and hear. sick. anyways they run a smaller charge pipe and they also have to use a stock exhaust to run the waste gate unless you run a twins setup. the guy that i talked to said that it would cost around 13k to run a twin setup if a kit was not available. which it is so that number is invalid. also they like to run the charge pipes in the rocker panels and put the intake under the rear bumper behind the tails. you essentially have one big intake pipe from the intercooler supplied by the charge pipe that run to your intake manifold. there is also things that are envolved with that. bigger injectors and one step colder plugs. also he recomends to run a water meth injection system with that to run safe boost. 6 with out meth and 10psi with meth. hope this will help somepeople wtih the rear mounted turbos.

Guy here in Utah that is installing one on his sedan. They said it would take 12 hours (took only 4 on the corvette). Its been in the shop for over a week now! lol

most of those things are standard with FI.

The pump is with the Kit, you do not have to buy it seperate.

$4500 for the kit (i believe that was the single turbo)

I'm sorry but idea of a boosted g just gets me happy in all the right places. I'ma go get a towel.

Well I'll admit that I don't know much about that particular system. But I cannot see how, with all that plumbing, this system could have little or no turbo lag? Could you please elaborate?I mean with that length of charge pipes, the volume must be huge. Unless of course they run very very thin charge pipes in which case you would have a big problem not only with pressure loss, but also with maximum flow capability.

On top of that, by mounting the turbos so far back you will also get turbo lag because you have a huge volume of exhaust pipe to fill before you ever get to the turbines.Again, unless you have very thin pipes but then again you run into pressure-loss and flow issues.

Of course, having a smaller turbo will reduce these issues, but then I don't think they could claim any of the numbers they do on their website.

Not trying to be Mr. Negative here. I would just like to understand.
