turbo

[Guest]

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.

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.

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....

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.
