>Then you have to ask is it worth the extra ducting drag and weight. I'm finding in my own research that it is better to reduce drag than increase power in minor increments. But an intercooler can work inside the cowl even without direct exposure to the airstream since the air inside the cowl (while still warmer than the airstream) has a lower temperature than the exhaust. As for two turbos... Aaron is right. The smaller twin turbos are designed to overcome "turbo lag" during acceleration which is important in automobile stop-n-go performance. For continuous power application a larger single turbo works better, even if it is routed further from the head of the exhaust.

... french wine!

Actually John I was hoping you would come up to KDNN to give me a ride to SNF! (see coffee house about thumbin to SNF) I wanted to see how the A/C was working... that and the rotary. I couldn't swing a ride with Greg's rotary before he yanked it for a turbine. Puh-LEEEEEZEEE! I'll give ya $10!

wait... S.T.F.U?!?!?! I just found out what that means... it is something used on the supervised teen-chat sites! Hey big C... where have you been spending your time on the internet? Hey I know, let me make you feel more at home... "OH those N'Sink boys... aren't they just dreamy!" "Yeah... my favorite one is Steven. He has such a cute butt." whoops... crap. I promised John I would behave. um... okay, less sarcasm, more constructive criticism: Yur Mamma!

... I'll even chip in $5 for gas!

okay... I'll leave Beuford at home, and Mr. Forrester will be in Vegas. Anyone flyin over KDNN? Not you dust... you know how I feel about Yugoslavian propulsian units.

Gee... I feel so bad about not quoting facts about automotive turbochargers hooked up to Lycoming engines in aircraft when there is so much raw data available. Bad MarbleTurtle.

Here we go again... Okay, I'll admit that most of my experience is with automotive turbo applications... but that is what we are discussing here so I'll throw out a few thoughts on the subject. First I'll say that I like turbos in automotive applications. I've had several. As for Chrysler, the only turbocharged vehicle I know of they currently carry is the truck with the Cummins Diesel... Garrett builds the Turbo for Cummings if I remember correctly. The Chrysler turbo cars from the 80's and early 90's did not have Garrett turbos. If I remember correctly, they bought them from Mitsubishi. Unfortunately Chrysler almost went broke with these cars under warranty. In High School, my friend Mike would always get to the McDonalds first in his LeBarron Turbo. But while I was flirting with Tracey trying to get a free McRib, Mike was still idling out in the parking lot. 3 turbos later, he gave up cooling off the turbo, and Tracey got fat. Years later I asked my mechanic why the Lotus Esprit SE would not allow full turbo boost for more than 10 seconds. "The Turbo would melt." Then I lived 5000' feet up on a mountain with a nice view. It was a fun drive in an Audi Turbo Quattro. That was the only time I could drive full throttle for more than 30 seconds, but that turbo would glow red by the time I reached the driveway. A few years later and a used Porsche Turbo became the transportation of choice. That one almost killed me... threw me off the mountain in a driving rain. Interesting car though... air (oil) cooled flat six with a big honkin turbo charger. Now its the reassurance of all-wheel-drive backed up by a twin turbo V6 in an Audi A6. Only the new Subaru WRX Sti 300hp turbo could possibly pry me out of this car. Take a look at the Turbos from Chrysler, Lotus, Porsche, Audi. The ones from Chrysler and Lotus were light, tinny metal, pieces of crap. The Audi and Porsche turbos' use heavy cast metal and were well made. But I seriously doubt even these excellent turbos could withstand continuous full application of power. Its not wear and tear you would need to worry about... its the ability to withstand a continuous blast funace of heat coming from an engine generation high power against high resistance continuously. Automotive applications were not designed for this... get one from a Semi tractor or farm tractor. They are designed for full power against high continuous loads. To believe an automotive application would work is living in a fool's paradise... or as my Dad would say... willful ignorance. How's that Dust?

What tha... a turbos a turbo? Sheese... can't wait to occupy the same airspace with you in that Yugo Turboed Lyco. Why bother with someone who knows what they are doing like Garret... just get a big ol' pinwheel off of juniors' bicycle... or one of those Tornado things advertised at 3:00AM on Speed Channel. You can't seriously believe that Chrysler is slapping a turbo on its cars designed for continuous full power use!

I need a lift to Sun-N-Fun. Anyone flyin by DuckTown GA wanna stop and give me a lift? It has a 3000ft dirt field which is okay if it hasn't been raining. Even if it has been raining my cousin George can pull us out if we get stuck. If DuckTown won't work... KDNN (Dammit GA) is close by. Its 5000' and has a windsock too! Be careful of Mr. Forrester though. He won Powerball a while back... but didn't finish his flyin lessons before buying a plane. He doesn't have very good no-tower approach eticut... he told me that ever since he got rich, his new philosofy in life is "Screw it, I got money." The FAA man tried to pay him a visit once a while back, but Mr. Forrester has big dogs and an even bigger gun collection. He still flies. Anyhow... if anyone would not mind stopping by and giving me a ride to the show, I'll make sure my dog gets a bath beforehand and is quiet on the ride down. Oh, and if anyone else needs a ride, feel free to use this post to tell where you need to be picked up from.

You need to move out here in the country... most people around here think they are just Cessnas flying in reverse. (How'd they do that?... why aint it beepin'?) Sad about JD though. I remember hearing about one theory that referred to a possible suicide intention. What was the final NTSB conclusion?

... I double dog dare ya to hook up that Chrysler turbo! You'll fall out of the sky faster than my kitty getting unstuck from a telephone pole with the good aim of my slingshot!

... like I need to go back on my medication.

"Take my Wankle for a Spin?" John, is any of this helping.

... "quick spin around the block?" get it?

You'll hear a waste gate or a blow off valve referred to as "pop-off" valves. I was discussing waste-gate valves. There are adjustable valves, but in automotive applications, the waste-gates I've seen all have a range from medium to high positive pressure. Neutral atmospheric pressure is no benifit to automotive tuners. I wish you luck.

I made a post in the Continental engine section that should probably go here... I thought I ran across a picture of a Cozy with a small block Chevy V8? Anyone know anything about it? How much will that sucker weigh? Hmmm... lots of torque down low in RPM range, no PSRU, crate motors are cheap, forget overhaul, just chuck it and start over, glass pack pipes, Corvette stickers on the body... heeyyyy...

... speaking of heavy. How heavy is a Chevy short block with no PSRU? Has anyone tried it?

You may have a difficult time finding a "pop-off-valve" that only allows atmospheric pressure. Without it, you'll be facing serious detonation problems that can only be controlled by a well programmed ECU and electronic ignition. A few high performance cars are running around with high compression engines and a high pressure turbo charger. But if the ECU ever has a brain fart, those engines detonate like artilery shells.

uh oh... here we go! "No valves no problem" "Take my wankle for a spin" "Watch me wobble my wankle!" "A short crank is better than a long stroke!" wait... I don't even know what that means.

Can't get the skyline... settled for the Audi A6 2.7 twin turbo quattro. Switching the small turbos to the larger set available in Germany bumps power from 280 to 450. Spiffy.

HERE HERE!!! Let's hope we all remain ignorant B*sds! ... always striving for the impossible. Wait... did that sound hateful?

... welcome to my world.

... how about the 10 habits of highly effective people.

I'm too clumsy to have an ego... and I write way too many post late at night that don't quite morning sound right .
