Ford's 400HP 5.0 (Coyote) V8 spied !

really? 7-20ishlbs is pitiful?

Which is it, 7 lb or 20 lb? The Cobalt SS runs 20+ psi but that is not your average turbocharged setup. We use 5 psi on an application that is used in an environment where it would destroy most vehicles.

Mazdaspeed3's run into problems at 15 psi, and WRX's/STI's are blowing turbos and pistons with less boost.

Your average turbocharged application would be something like the Ford/Volvo T5, Saab's, and Audi 4-bangers. They are designed for longevity rather than performance.

both. depends on the engine. for diesels 20lbs isn't anything. stock evos run 20lbs from the factory, i believe. stock SR20DET's run 7ish and can run around at 14psi wth no problems at all. same with supras and other well designed factory turbo engines. the new genesis has an engine rated for 29psi and the turbo maxes out around 14psi.

a turbo can do whatever you want it to, its the engine that is the weak point. if you push a little turbo way passed its efficiency range you're asking for trouble. the only time a turbo fails is:

1. people beat on them and dont let them heat cycle before they shut the car off which takes all of a minute or so. this isn't really a big deal these days with the sophisticated cooling technology available.
2. an engine frags itself which kills the turbine wheel which frags bearings which means you need to rebuild a snail.

the problem with turbos is that they aren't idiot proof like blowers and they have a little lag especially if its a power dependent part and not a power adder (like a supra vs a TT viper). with the advent of variable geometry turbos like in the 911 turbo and other cars lag is no longer a problem either.

everything from smart cars to snowmobiles rock turbos from the factory. blowers are cool but turbos have the advantage especially when a company puts all that time into making the systems cost effective and compact.

then you get into the fuel economy aspect of it all. the primary advantage of turbos is that they work when you want them to and not when you dont. aside from camgear equipped blowers this can't be said for superchargers.


meh, this is useless. i like both, you guys dont like turbos. i get it. whatever.
 
The turbos that are used in extreme environments and have to last for a long time aren't pushed very hard. Think max boost of 5 psi.

:rolleyes: Are you serious..

The truck that brings the food that you eat to the store has a turbo and will go a half million miles or more in it's lifetime.. those trucks run 30+ pounds of boost..



Many production cars have had turbos and lasted just as long if not longer than supercharged cars..

Plus what is the difference if 15 PSI comes from a turbo or from a S/C the motor still has to deal with the extra combustion pressures that 15 PSI creates, it does not matter how that extra pressure was created.

So please explain how a turbo is more harmful that a S/C
 
Blown 6 you speak of is the ecoboost 300hp twin turbo v6... Yes thats rumored to also be in a stang in the 2011 range. Lincoln MKZ is the first model i think thats supposed to come with that engine.

The EcoBoost is going to be in the 2010 Taurus SHO and have 365HP. The EcoBoost itself is safely capable of 415 HP with the existing internals. The F-150 line up will have this engine available as well.
They've announched on Feb 18th that they have done a significant upgrade to the drive train (Transmission, Torque Converter/stator/larger rear gears). Ford approved the engine for the later 2010 Mustang however the HP rating was not announced.

Maybe MY 2010 but as of right now the standard V6 is in the 2010 Mustang.
