Had to brush up on my fabrication skills for this project.
I bet you will be able to wash that bridge with that one !!!! YEA BABY YEA
Mark that is really starting to look like something.
Hope I have as much luck!
Can't wait till I get the turbos from tom. :D
Can't wait see the finished product and the numbers yoy get. :p
What kind of turbos are you using?
The tag on the turbos says Garrett TV7701.
They are only good for an EFI system as they have no vaccuum seal that would be needed for a draw through setup.
Here's a pic of the tacked up headers with some jigs I made up so I can duplicate later.
I had to appoint a vicious guard beast to watch over the new parts.

Looks great. Those TV77 will be good for a ton of boost. What kind of waste gates are you going to put on? You also may want to get some stainless sheilds made to keep from boiling the fuel and burning the fiberglass. The headers will be glowing red as soon as you hit boost. Very clean looking. If you're going EFI get a box that can drive 16 injectors. Hilborn stopped making the 120 lb/hrs so 95's the biggest out there.
HeavyHitter, I am going with a Haltech EFI system. I met this local racing legend guy Turbo Tom Earhart while boating this summer who is a fuel injection engineer at Bosch. He is a distributor for Haltech. He recommended going with 148lb/hr injectors for gas or 180lb/hr for alcohol. I guess he has a source for them. I will be using an intercooler and one 80mm throttle body. Tom says that setup will get me 1500 hp which is what he dyno's with the same setup on his 572ci Arias engine. That should be about 600 hp more than I got with the blower. Tom gave me some dyno torque figures that were similar to what you relayed in the other thread. Like 1000 ft lbs at 3000 rpm. What a stump puller !
He said that with the Haltech system his engine will idle smoothly at 600 rpm even with the long duration cam that he runs. Tom wants me to mount the wastegates right on the exhaust housing. He likes to remove the sandwich plate from the wastegate and have the wastegate valve seal right on a flat surface machined on the exhaust housing. I know the headers will run red hot so thats why I went with stainless tubing. I don't know why they would boil the gas though. It's an open engine compartment. Thanks for the input.
Unchained,
Something to consider, you may want to support those turbos with something other than the headers. That's a lot of weight hanging out there. Add in the red hot primary tubes and some bouncing from the boat and you may run into some problems. I'd hate to see your setup damaged after running it a few times.
Nubbs, I figured on a support down to the block or the head from the turbo exhaust flange. Those turbos are quite heavy. However I think that I will be reducing the overall weight with the turbos as compared to the blower. My new headers will weigh less than the previous Bassetts also.
what were you going to do with your blower setup? let me know. sean
I've got the headers all welded up and the turbos bolted on. Now I'm ready to build the intercooler. I found a new heater core for a bus that looks like it will work good for an intercooler core. It's 13 1/2 " x 8 1/2" x 3 3/4" thick with copper fins and brass tubes. I got it from a local radiator shop. I think he wants about $ 50 for it. I'm going to build an aluminum box around it and it will mount down to the top of the Victor 4 bbl intake.

I need to find where to get those air cleaners that clamp right on the turbo compressor inlet. I've seen some that were a bell shaped unit with a coarse screen over the end.
K&N. That is looking bad ass! I`ve got to have one. I am looking for a pickle fork, any body got one for sale?
Mark,
Tom still have a Job over there in Kirkland? Word has it here that Bosch is moving that division to SC. I have never met Tom but have heard good thing about him.

]They had a thing in the paper about the Bosch plant possibly closing. Tom said even if they move production, engineering will be there until 2004.
Tom's an interesting guy. He had a drag sled that went 175 mph. He held the national record for years.
I took the band clamp off the turbo and removed the center section to look in the turbine housing.
The entire exhaust flow from four cylinders of the engine funnel down until it hits the turbine wheel from a 1/2 wide slot that is about 3 1/2 diameter x 360 degrees around the turbine wheel. Its amazing that something so small can drive the compressor wheel and be capable of making 50 lbs of pressure. [img]http://free.***boat.net/gallery/Gearhead_Garage/Motors_and_Drives/Turbine_Housing.JPG[/img]
The turbine wheel is 3 1/2 diameter.
[img]http://free.***boat.net/gallery/Gearhead_Garage/Motors_and_Drives/Exhaust_turbine_impeller.JPG[/img]
So it takes two 3 1/2 diameter turbine wheels to make more pressure than you can get with a roots blower with rotors that are 15 + long. Hmm, makes you think.
Tom never got back to me and I got tired of calling. Sooooo, I went to some other place. I had to sitck with the T4's because of the draw through and the carbon seals. Still will make more boost then I want so it should be ok. I got 2 of those big Pro wastegates that Invatiove Turbo makes.
What are you doing for waste gates? And I'm assuming that you will make a spool and mount the gates between the headers and turbos.
Looking good btw. Nice to see other ideas.

So it takes two 3 1/2 diameter turbine wheels to make more pressure than you can get with a roots blower with rotors that are 15 + long. Hmm, makes you think.Those things are cool. The proper term for that is a "Radial Inflow Turbine" It is similar to small turbine engines used for auxillary power on airplanes. They extract nearly all the energy from the airflow. None would be left for thrust if you tried to use it for the airplane itself.
The compressor section is a "Centrifugal
Compressor" It causes the air to compress by throwing the air out radially through "Divergent Ducts" The air slows down in these ducts, but due to more air being continually thrown in, it causes the air to compress (pack). Not nearly as effecient as an axial compressor but much more rugged and durable.
The roots blower does not compress the air in the blower. It just provides the engine more air than it can draw in by itself. Big air pump. This force feed causes the air pressure to increase in the manifold.
Sorry, My aviaton technical instructor days came out suddenly.
What an awesome project Unchained.
SuperDave: Looks like throttle pedal wastegates. :D
[ December 07, 2002, 03:13 PM: Message edited by: Infomaniac ]
Info those are the same wastegates I use :D
Ron, Thanks for the tech info {info}.
Dave, I still need to get wastegates. Tom has a specific spot where he likes to have them mounted where they work best. Too bad Tom didn't get back with you but I think there were some temporary medical concerns. The T04s should work real good. Tom says that the vaccuum seal is a tiny drag that makes them spool up a little slower. I always ran a draw through setup before and never noticed any lag.

I got brand new ones for less then he quoted those re-built ones. Anyway the guy I went through said the same thing about the seals. It's not a dragster so I'm not sweating it. I'll catch 'em on the second lap!
Mine do not take too long to go, Sd you will be
fast enough.
Unchained how is the project coming along?

I'm waiting for more parts to come. I found a source for two real nice CNC machined 63mm throttle bodies from a guy in the Chicago area and for the last two weeks it's been. " I'll send those out today" Their still not here.
After I get the throttle bodies mounted on the sides of the intercooler cover then I can make the aluminum tubes from the compressors to the throttle bodies. Past that I need to,
Buy wastegates and mount them on the turbine housings.
Machine spots for the injector bungs into the intake manifold and weld them in.
[img]http://free.***boat.net/gallery/Gearhead_Garage/Motors_and_Drives/Turboinstallation9.JPG[/img]
Thats going to be cool. It looks like you have enough room for injectors and rails under your intercooler.
I got a set of split top cmi's from Super Dave. I've got a tall deck block and some dart heads. I'm going to build a new system for my boat, It's going to take awhile.
If anyone else is interested in doing a project like this I can supply a set of 2" stainless steel turbo headers like the ones in the picture for $ 1000. a set. All TIG welded.
[img]http://free.***boat.net/gallery/Gearhead_Garage/Motors_and_Drives/turboclearanceinlibertor.JPG[/img]
They will go on a jet or Vdrive application.
Single wall construction so they would only be for an open engine compartment.

Hmm, makes you think.Difference is that the rotors in a blower spin between 5 and 10k rpm depending on pulleys, and those little turbine wheels spin about 60-100k !!!
I have the intercooler about done now, here's a picture showing how the waterlines run through the cover. I used 1/4" threaded rod bent into a U shape with rubber hose slid over it to attach the core down to the base.
http://www.childsdale-ind-prop.com/turbointake2.JPG
http://www.childsdale-ind-prop.com/intercoolerrv.JPG
We machined the holes in the intake manifold for the injector nozzles and I made mounts for the wastegates on the turbine housings.
http://www.childsdale-ind-prop.com/turbointake.JPG
Now I'm fitting up the 3" OD aluminum tubing that connects the compressors to the throttle bodies.
Next I'll need to remove the oil pan to weld in a couple fittings for the turbo oil return lines.

That is awasome man. I wish I had the time, money and space to do that. The making tape should hold for a while LOL.
I have an aircraft turbo that I was considering putting on e-bay. It is for a 540 Lycoming. What a beast.
Never mind!!!! idea

Whats Up with the Project?
Lets see some more Pictures! :D
More pics
[img]http://free.***boat.net/ubb/Avatars/Gearhead_Garage/Motors_and_Drives/1DSC01444.JPG[/img]
Ill pipe the two compressor intakes into the back of the scoop using two 3.5 aluminum tubing 90 degree bends.
[img]http://free.***boat.net/ubb/Avatars/Gearhead_Garage/Motors_and_Drives/DSC01443.JPG[/img]
Im going to feel like a butcher when it comes to chopping a 3 1/2 x 7 hole in the back of that shiny scoop.
bro... this is great youve done a great job on this i dont know about the radiator/intercooler but if you think itll work go for it. one of my buddies has a 454 twin turbo gail banks shiada it hauls . youll have fun good work again!
Mark not shure how to get the Damn Picture up so heres the http://www.hotboatpics.com/pics/showphoto.php?photo=672

Hey
I have a complete Gentry Turbo engine for sale.
[img]http://www.***boat.com/image_center/data/504/1001_engine.JPG[/img]
or would separate the turbo kit,
or even have a Brand New Gentry Turbo Kit for sale.
Email me at agt001@aol.com for more details and/or photos.
http://www.hotboatpics.com/pics/data...C-052S-med.JPG
George, That's looking really good. Those turbo's should get some good "ram air" effect with the compressor inlets aiming straight forward and you can still access the valve covers easily.
A good source for aluminum tubing bends to pipe the compressors to the intake mainfold is "Woolf Aircraft" in Detroit area.
I got some pictures of the new boat. Havasu Hangin ( Jeff ) was nice enough to offer to make a 45 min drive to where the boat was at to take the pictures. It looks like the hull will be ready to haul to Hi-Tech Performance soon.
