I had never really thought about the housing itself as being restrictive since it has the impeller, but I guess it can be. In which case, superchargers have that and they are belt driven.
My above description was very general and not meant to be an engineering tutorial, hence my usage of the "cow shit" description. I suppose I will have to give one next time that way I can enjoy puffing myself up also by giving one.

the stock internals should be ok with 11psi of boos from a supercharger but i'm not sure for a turbo. a turbo runs hotter but has no parasitic load from a pulley like a supercharger so it will make more hp at 11 psi than a supercharger would. i hope everything goes well for ya. i plan on going boosted in March-April from Justin's 11psi procharger kit. my friend has a 2001 v6 and is running a 11psi kit and has been romping on it for a about a year no and has not had one problem with it. his car has over 75,000 miles on it. he has 365 RWHP from a H/c/i swap and the supercharger. i'm just suprised his stock 5speed is still in 1 piece. |

Thanks. I am kinda worried about my auto, but if it goes out I can always upgrade to a 5 speed, so it wont be too bad.

Well then give one instead of beating around the bush and allowing your "Turbo Gods" to come in here and do all your talking for you.
Respond to tbird and fast64 and show us you do know what your talking about.
Sounds like you're the one that didn't think through your posts and not Fast64. |

I know next to nothing in the turbo category and I will say this. The turbo is a restriction, no matter how you say it. Sure you may lose some power but I guess it's all about which makes power right back...
BTW DRUNK

Didnt think of the housing being a restriction? The housing is what the air flows through, to get to the impeller, and the housing is where most of the air backs up and "gets in line" to flow over the turbine. |

EclipseGSTdude you are right psi is psi and its what kills the motor, I ment it in a bit of a different way. You see alot of people that have screwed up their motors when running a blower. They blame it on to much boost when at times its the horrid tune that done the deed. PSI can definatly kill a motor, alot dont get good tunes it all I ment.

ok first off its not all about CFM its also about pressure drop across the core. so the cheaper Ebay cores can and do have more pressure drop across them. soo spend your money where you want. i am gonna just save alittle while longer and get a good core.
also i think you have it backwards. a centrifugal(vorturd,procharger) will make less boost from 2k-4k than any properly done turbo kit. they make more boost with RPM. soo at lets say 3k they make 4lbs at 6k they will make 9lbs. soo Andy has that part right for sure. now a turbo will not have the Instant boost that a positive blower(kenne bell,eaton,wipple) will.
oh yea every turbo kit i have everdone or worked on has max boost by 3400rpm. my little junky homemade turbo kit has full boost by 3200rpm. and thats ether 15psi,20psi or 28psi. thats the wonderfull thing about turbos. quick boost for great tq and then also pulling high hp up top.

PSI isnt what kills engines. I dont care what anyone says.
Parts are not rated by horsepower, PSI, rpms, or any of that. They are rated by tensile strength.
The reason people think PSI kills engines is because generally when you raise boost, you also increase the possibility of detonation. Detonation is not always audiable. And for anyone that knows about detonation, it causes extreme stress on the engine, trying to force the piston and rod in different directions than its meant to go, and wanting to push it back down while its on its up stroke. Thats what kills parts. Ive seen pistons chunked, rods snapped, holes in blocks, all because of detonation.
The reason people say its PSI is because more PSI means you need more fuel, and when people say "my a/f gauge reads its rich", theyre basically saying "my twinkly gauge that isnt worth shit makes me think its rich", and they think its safe. Then when they blow it up, they blame it on running more boost.
if i remember correctly, white95v6 ran 28psi on a stock 4.2L rotating assembly, and its still in one piece as far as i know.
Thats why i always say, get your car tuned properly, using a wideband 02 sensor, everyone says the 5.0 breaks at 550hp, yet there are guys running around with 680rwhp on a stock block because its tuned properly, and a very good setup. |

Well than what do you want me to talk about? Sorry if I don't like to waste my time trying to convince people who think they already know how everything works instead being open to something that might *gasps* be in disagreement to what they've always thought. I'm no master debater so I don't try to be. I'll also be the first to admit I don't know everything and learn new things from this and other forums everyday. But don't be fooled, I'm doing my research before I go and try to do something that could ruin the only car I own.
Here's a nice little nut shell
The reason I had never really thought about the turbine as being restrictive is because of the blades helping to draw the exhaust through by creating a vortex and then a suction of sorts through the turbo housing. Sure if it was just the housing it would be restrictive, but then that would defeat the purpose of the whole thing. That's why I never really considered it.
Of course psi can kill motors, if you put a 50 pounds of boost on something completely stock, yeah your going to end up with a couple rods through your hood and back down through your roof, and a few nice gouges in the pavement where a couple went through the block. BUT, if you use common sense, and don't run stupid amounts of boost and this still happens, then it's because of a bad tune. Proabably, in a nut shell, the whole situatuion is this:
No common sense + too much boost = blown engine.
Common sense + safe amount of boost + bad tune = blown engine.
Common sense + safe amount of boost + good tune = perfectly fine engine for more than 100,000 miles most likely.
For the record, I have never asked my "Turbo Gods" to come in anywhere. I don't think Andy even knows what my forum name is, just my real name and e-mail address. I don't pull the "My big brother is going to come in here and beat you up!" BS.
I do, however feel the need to apologize to fast64, I should not have said that.
Now, given the choice of who to listen to on turbo matters, those who actually work on turbo charging Mustangs for a living, or those that like to bs around on forums and like to puff themselves up by being able to say they posted "technical information" in the poweradders section even though it was something out of their ass...?
Hmmm...let's see a show of hands as to how many people have actually turbocharged a Mustang that have been posting technical info in this thread. Looks like it's Andy, White95v6, and tbird having tb'd a tbird (which is probably very similar). Yeah I think I'm going to listen to what they have to say.

DarkShadow, i do have a bit more respect for you after posting that up
As for your vortex, thats what you would think, but it doesnt work like that. When the turbo is creating boost, its under a constant load, thats basically what boost is, its air that your turbo is FORCING into the engine. Not only is the housing a restriction, but the impeller is too, because once it creates boost, there is a large amount of resistance placed on the shaft (how much resistance, i couldnt tell ya), and the exhaust gasses have to overcome that force, thats what creates boost, not the turbo freewheeling.
There is a saying "there is no free lunch", basically saying, youll always have to pay for it one way or another. A supercharger places large amounts of stress on the crankshaft. A turbo places a large amount of heat, and piping, and a bit of restriction on an engine, nitrous is pricey over time. There is no perfect power adding device, everything has a downfall, wether we like to believe it or not. |

^ unless we all went to my hybrid theory where you get all the extra heat energy from your breaks for free. sure you'll need a few more batteries and the electronics but that's cheaper then any other power adder. some of those DC motors put out the equivalent of 80 HP. Imagine a 4.2L NA V6 putting down 270rwhp and then with the DC motor kicking in, putting down 350 rwhp and a crap load of torque. electric motors have a ton of torque. the prius electric motor puts down 295 lb-ft of torque between 0-1200 RPM's.
but that's another argument topic for another day.
anyways glad were working things out.
