Anybody here running twin turbos?

If Yes, interested in links , pictures for pipe routing etc.

no, cost to much and there is no gains over a singal

[T-Punk]

There are minor gains over a single tubo but the cost to make a twin system doesnt really make it worth the gains. Basically with twins you will have less rotating mass and you can concievably mount them closer to the hotter exhaust gasses than a single. This would give you slightly quicker spool. But as viper said it cost to much for most people.

BTW Viper, your pics on your site arent working right now. I'm gonna need them when i go to put the rear end in next weekend so if you could get them back up or email them to me I would really apreciate it. Thanks.

yeah i moved severs let me whats up with them

[Turbo V6 Camaro]

okay i think i got most of them fixed

The idea behind twins isn't power gains over a single, it's that twins behave differently than a single turbo. So of course you wouldn't go twins for "the gains" over a single, you'd do it for the kind of performance that is inherent to a twin system.

To say it's not worth going twins because it won't give you more power than a single is ignorant.

i wasn't trying to pull out Quantum Physics on the noob.....

i don't really see where almost double the cash would be worth it unlees you had a 2L motor and trying to spool a T-76 or something lol

maybe for auto cross?

thanks viper.

It doesn't always work out to double the cost unless you make it that way. Sure if you went with twin GT series turbos with Tial gates and all that, it would add up pretty quick.. but if you did something like a twin 16G setup, then it wouldn't be too bad (except for the scavenge pump setup)

You could use twins for about anything you'd use a single for. Need is a relative term, so you can't just base it off of that anyway. Like i said, it's the difference between how the turbos perform. Generally Twins come on a bit softer and a bit sooner (most parallel TT cars will feel somewhat similar to an N/A car), where as a single will come on alot harder and later. Just depends on what the builder wants.

you said with the same size turbo i though most went with a small and a bit larger turbo ?

[T-Punk]

Viper, the only way you can run different size turbos is in a sequential style turbo setup. If you run them in a standard style setup you will have one bank with more backpresure than the other. The turbos must be exactly the same for a twin setup. If you want to learn more about a sequential setup talk to the tractor pull guys, some of them are running quad sequential turbo setups which is insane. But from my experience (which i admit is limited) twins feel more natural in the way they come on than singles. Singles let you know exactly when they hit even if they are setup correctly.

:D i know i'm at 3 psi with out looking

ya know what, i think I'm going to read up a little more and do another write up that will go into deatail on different types of turbo systems and advantages/dissadvantages of each. I still think that my intro to FI in my sig should be stickied as well but whatever. I just get bored sometimes so i write down my limited knowledge for others to peruse.

Why it should be the double cost?
Just 1 extra turbo and the rest is the same , yes maybe +scavenge pump.
I have 2.6TT engine from 2001 Audi hanging in the garage. (front damage , bent valves,damaged cylinder heads..), nice setup, 2 smaller turbine goes right on headers. Very compact.

i said almost and you need 2 wasgates also plus it take alot more piping
