turbo

try a Ford 6.0L engine that redlines at 6000 rpms. and it is a the ford f250 and f350. and the new ford 6.4l desiel will do the same.

Son, it looks like you're going to be taken to school....

Go to this link:

Click on Interior and it will show, through all the annoying flash player crap, the gauge cluster. Oh what is that? The tach TOPS OUT at 5000 RPM? Oh and you know what, the engine will never rev that high either, because as a marketing ply manufacturers ALWAYS add a higher range to the tach and speedo, than the vehcile or engine is capable of acheiving in production form. I'd say that red line on that diesel will still be around 4000 RPM, too bad they don't show a "red line" on that tach.

I haven't been able to find engine specs like GM publishes, which is what I was looking for but that interior shot showing the tach is indication enough that you're talking out of your ass, yet again.

And just as a FYI. I have personally owned, built, and driven a 11.1:1 compression ratio turbocharged car. It ran on 91 octane pump gas. High compression + a turbo can be lots of fun.

Most gas engines will have between 150-225 psi in the cylinders when doing a compression test.

Many of the hot compressor setups for diesel motors are also the hot compressors for gas engines. The newest bandwagon for the Honda and Supra guys are Borg Warner turbos... The Borg Warner turbos are the exact same as the Holset units that are used on MANY diesels.

Show me a production diesel engine that redlines at 6000 rpm.

x2! The only diesels I know of that go to 6000 RPM, are built specifically for racing, and even then, 6000 RPM is a feat to behold.

Yes, kevin535, you DO need to do a LOT more research, you may know something about diesels, but you show VERY little knowledge about turbos or turbine theory, or even basic engine (fluid) theory. I love guys like you that say "Oh that won't work right because blah blah blah", when people do it and it works VERY well everyday. The only time there is any extended "lag" from using a turbo is because it was improperly selected (for size, trims, etc.), not because it came from a diesel.

You also need to a bunch more research on the 660, since the lowest the 660 was for SCR was 8.5:1, which was back in the early '80s, later versions went to 8.9:1 in both the genI and genII versions, then with the introduction of the genIII a raise to 9.5:1 was seen and later up to 9.6:1, whihc works just fine with a turbo, contrary to the old myth that you had to lower SCR to use a turbo.

Additionally, if you feel we belittle people, that is a personal problem of yours that you are going to have to deal with. The information on these engines is so skewed all over the interenet that we don't want that misinformation to continue on this site, so we will correct you, or anyone else that perpetuates any myth or incorrect information.

I don't know anything about turbos actually. I thought about the same idea since we have turbos for our tractors....they redline at 2250 rpm.

What was that race car ....Audi? put out a kick ass turbo diesel.

[kevin535]

yes, I need to do some resreach on trubos. I work a ford dealer and work on desiels all day I know desiels better than most of you. A desiel typ. had a compression ratio of 21 to 32 to 1 and a desiel engine needs about 400 psi to run where as a gas engine needs 90 psi to run gas engine has 8 to about 10 to 1 compression ratio. yes you can put a trubo on a desiel on a gas engine and it will work but it will have a bad trubo lag. bigger is not always better. Actually a desiel will redline around 6,000 rpms so raven you are wrong about that. not all trubos are alike because trubos are designed to specific engine sizes to build the correct boost and get to most power out of an engine. A 60 deree v6 has a typ . compression ratio of 8.5 to 9 to 1 which will turn some turbos off a desiel but of exhast flow out of a desiel is much more that a typ gas engine. And no I do not need to do any research. you guys are a bunch of asses because you will attack any one and belittle them if you think you are right.

You would be surprised. Many diesel turbos are commonly used on gas engines with great results. Many turbos used on gas engines are also used commonly on diesel engines with great results. Exhaust gas is exhaust gas. There's not so huge of a difference that the turbos aren't interchangeable. The biggest thing you'll see is that most diesel guys tend to oversize their turbine sides while the gas guys tend to undersize them.

Tim

QFT!

Any so called difference in the turbine wheel is purely due to trims, or the differences, not because one turbo was supposedly "designed" for use with diesel or one for gas.

Just look through junkyardturbos.com, or turbogms.com for the use of diesel turbos on gas engine with EXCELLANT results. As stated "exhaust gas is exhaust gas. Really it just comes down to how much volume of that exhaust gas is being spit out by the engine, not what fuel created that waste energy.

yeah but a diesel turbo isnt as effiecent as a gas turbine turbo.. the spacing and design of the fins on a diesel are much more spaced out because of the excessive heat and volume of gases exhausted from a diesel engine... if you dont want boost til about 4-5k rpm go for it... ill stick to have full boost at 2800 rpm... less lag FTW

lol dude i'm still kindof a noob to. I'd suggest you read http://auto.howstuffworks.com/turbo.htm ... http://www.turbo-kits.com/how_turbos_work.html ... and this http://www.turbotechnics.com/docs/turbo/turbowork.htm this will give you a basic understand of how it works. Basically it turns a pollutant into energy haha. Oh and btw if you were thinking this would be a cheap job its not. Expect 2-3k for a safe turbo setup. Also you have to build up the cars engine a hell of alot. Then suspension for the speed... exhaust. Just alot of stuff. Any more questions just ask.

Just want to add to your list of reading...

Thoes desiel trubos are designed to spool up with a lot of exhaust pressure like what a desiel puts out. A 2.8L is too small it will not put out enough exhaust flow to spool up the trubo and if it does then it will be near the red line. which is useless.

You need to do a lot more research.

There are plenty of guys using diesel turbos og gas engines.

Here's a tip for you, I usually don't give out free info like this to someone who blatently states wrong info, but I'm feeling generous today.

A diesel turns at about half the RPM that a gas engine does. Most diesels redlijne, REDLINE at or before 4000 RPM, most larger diesels redline by 3000 RPM, some of the "hotter" diesels are about 3500 RPM. So what does this mean? That means that a diesel engine at twice the displacment of a gas engine turning at half the RPM will put out the same amount of exhaust flow. So that makes using these "useless" diesel turbos on gas engines quite useful actually.

give me 3 grand and ill turbo your car for you... but you still have to buy the parts...lol
