best turbo system

[c a m a r o]

whats the best turbo system out right now? are twin-turbos good or bad... i read that twin turbos actually slow down intake or something like that. is a garrett t-72 a good turbo for a v8 5.0l and up?

Define best.

to complete what 454 said define best for what aplication

[454Casull]

Anyway, the best of each application can be had if you have enough money.

[Sluttypatton]

There is no single "best" for every application.

I believe he means "Best" as in better than the rest... Geez, I'm a useless poster sometimes.

A twin turbo setup certainly does not slow down intake, but rather it "takes air in". Is that a complicated concept? I've heard of a guy who twin turbo'ed his 1990 Mustang LX (a 5.0). He used a sequential turbo setup, which means that a smaller turbo spools up quickly to produce less boost while a larger turbo spools up slowly to produce substantial boost. Therefore, you can still get decent off the line performance while maintaining top end performance that turbos are known for. However, this setup is difficult and costly because you need to replace a multitude of parts to deal with boost on a n/a vehicle (bigger injectors, bigger fuel pump, reprogrammed ECU to retard ignition during boost, possibly a new block, lower compression pistons, new piston rings/gaskets, heat shielding, etc). Also, to prevent detonation in f/i situations, you need an intercooler or in this case, twin intercoolers (or one massive one). On top of this, you need a custom headers, numerous mandrel-bent pipes, oil lines, turbo lines, and a free-flowing exhaust if you dont already have one.

That's alot to fit under the hood with a V8, isn't it?

That's my

One type of turbo setup might be better for your application than another. What kind of car and engine are you wanting to turbocharge? There are so many things to take into account when think about having the best setup. Things like turbo size, intercoolers, number of turbos used, compressor maps, and the list goes on. To be general though I would say that Twin Turbo "Sequential' setups are better for larger displacement engines while a Single Turbo setup in better for smaller engines.

for a 3.4l v6, or a 5.7l v8... or 5.0l v8 305.

I would go with a Twin Turbo "Sequential" setup.

sequential isnt as much as far as volume, but pressure.. they use sequenmtial in tractor pullers + high altitude private planes. if you pick the right size turbo, not only will you not worry about lag, but you'll have plenty of boost.. if you will up with 97 octane and have 8:1 compression ratio.. you can count on about 15psi after intercooler.. think twin turbo on V6 V8 applications, and one larger turbo with I4- I6 apps... for a 5.7 or 5.0 engine get a couple t-3's with a .64ish A/R. or smaller.
for the V6 definetly go smaller ro you wont reach full potential.

is t-80 better for a v8 than a t-3. and do all turbos necessarily have to make that gay rice noise? i like the way my car sounds, i dont want it to sound like an angry bee.

[Sluttypatton]

There are a couple of sounds related to turbocharging, the sound of the blow off valve, and the sound of the the turbine wheel compressing the air. Some blow off valves are very quiet, how loud just depends on the blow off valve. The sound of the compressor doing it's job depends greatly on the turbo and how much boost it's creating. It's possible to create an ultra quiet turbo system, many stock ones are.

But I don't see why it matters. That's the ricer mentality only in reverse. If my car ran a 10 second 1/4, but sounded like a weed whacker, so be it. The thing that people hate about ricers is that they like to present their cars as ultra fast, race machines, when in actuality they are bone stock. If your car is fast, the people who's opinions actually matter will respect your car no matter how it sounds, because anyone who discriminates based on the sound of a car doesn't know anything about them.

You don't need to own a Honda to know about rice.

[Sluttypatton]

Actually I'm a Dodge and Mazda owner.
