How many turbos can you cram...?

Perhaps I will sound like a caveman, but momma told me that there's no such thing as a dumb question. Anyway... what would happen if a person (not me) were to get twin remote turbos installed in the back of the car, then put twin turbos under the hood? What would happen with the 4?

for one, pretty much be a very inefficient system. You would also likely need lots of fuel and a very beefed up motor to take the abuse.

if you can fit two good turbos under the hood the rear ones would be useless. IMO twin ball bearing 50trims will probably be enough for most, and if anything would be easily upgraded later to 60trims or such.

Re: How many turbos can you cram...?

the number of turbos is not directly linked to the amount of power they can create generally speaking of course. In many cases a single turbo is better for power than two for example. It all depends on what you are trying to do.

Might you explain to me how one turbo is can be better than two, and under what circumstances that might be true?

One properly sized turbo will be more efficient than two.

circumstance?

just look at the worlds fastest supras, 90% of them will be single turbo.

Two small turbos that spool fast and die up top or one bigger turbo that spools about as fast and has a topend.

Correct me if Im wrong but basically thats why.

yes and no.

alot of people size their turbo incorrectly for their needs or goals. especially coming from a dsm world, alot of people throw on a large 60trim and support but get spanked by someone who did their homework and went with a smaller bb 50trim that was correctly sized for his needs. its all in correct sizing, sure a larger turbo flows more air but if youre under or over its efficiency range youre either gonna underrun the turbo or just create excess heat and less power. like i always tell people, if you want to run a certain amount of boost, find the correct turbo that makes the most airflow at that psi and is right in its efficiency range.

Re: How many turbos can you cram...?

it also depends on what you want to do.... and how you want to go about it. You can only put so much air into a confined space~ thats all an engine is... an air compressor. So there is definatly a limit.

Re: How many turbos can you cram...?

I've seen 8 on a Chevelle(i think, may have been nova). Either way, 1 per cylinder... Weird to say the least.

Yeah, that was it. I don't remember. That thing was probably the brightest red I've ever seen. And pretty small turbo's indeed.

But there is only 3 "banks" of cylinders, so how would it have 4?

Re: How many turbos can you cram...?

From Wikipedia:

A W16 engine is a sixteen cylinder piston engine in a W configuration. All W16 engines consist of four banks of four cylinders (two juxtaposed V8 engine blocks), coupled to a single crankshaft.

I think you are thinking about the W18:

A W18 engine is an eighteen cylinder piston engine in a W configuration. Recent W18 engines powered the Bugatti EB 118, Bugatti EB 218 and Bugatti EB 18/3 Veyron concept cars in the late 1990s. This engine featured three banks of six cylinders set 60 degrees apart.

Re: How many turbos can you cram...?

ooooOOOOOooo.... ok. See the only actual view of a W16 is from what I remember several years ago before it went into production, in which it consisted of 3 banks. I'm a moron, I learn something yet again.

Bump, read about the W18 Craig. I see where you are coming from now, but they are completely different engines.

I didn't know much about the W18 besides the fact that they produced it lol. So I was lost as well.

prolly thought three banks cause a W has three peaks and two valleys. i thought it would have banks as well, 4 would mean its a VV not a W

A VV is a W. A M is a VV or a W that got too drunk and fell off the bar stool. An A is just a V that fell of a bar stool and now nobody likes it anymore.

quality, not quantity

you need the right sized turbo or turbos for maximum gains.

Re: How many turbos can you cram...?

i cant find anything about the turbo specs for the veyron. seeing its a 8.0L W16 and has 4 banks of 4 cylinders, each bank is approximately 2.0L of displacement, off the top of my head id imagine something ball bearing that was the approximate size of a 50trim on each bank. then again, it depends on how much boost they are creating as well, the turbo is probably sized for efficiency for the amount of boost they designed the car to run.

what would be really neat is one of the variable pitch turbo's that porsche and i believe the cummins diesels are now coming with. down low the turbo has the charecteristics of a smaller turbo which spools fast, then as rpm and load increases, the pitches of the blades on the hotside change to give the turbo a larger charecteristic to flow more.

Re: How many turbos can you cram...?

So... what's the best setup for a 98 GT with PI heads/cams/intake???? And, if I buy a turbo, how easy is it to make my own setup instead? Just out of curiousity... if I took the turbo out of my g/f's wrecked Dodge shadow, could I use it? Or would it be worthless for the stang? SORRY IF IT SOUNDS DUMB, BUT I KNOW BODY WORK... NOT ENGINES UNFORTUNATELY

Re: How many turbos can you cram...?

i think the shadows turbo is pretty small, so no, it would be a awful setup.

the smallest i would go on a GT would be twin 50trims if you went with the tt route. anything smaller and you might run into issues with controlling boost since so much exhaust will have to be routed around the turbo because it wont take much to spool smaller than 50trims up, so you might run into a wastegate ineffiency issue, where no matter how much the wg tries, it wont be able to keep up with the flow and that exhaust ends up going through the turbine, and you get boost creep, which would be very bad if youre intentionally trying to keep the boost at a minimal level.
