Flatbottom V-drive. The system is from Gale Banks with an intercooler. Works great in the boat. To do a street system would present alot of different problems such as where to get manifolds to mount the turbos. Plumbing the system, draw thru or blow thru. The blow thru would be the easiest as the carb would remain mounted on the intake manifold. The problem with a blow thru is the carb can't handle any more than about 9 to 10 lbs of boost. Carb metering goes south above 10 lbs. Also the fuel pump would have to be boost reference. These are just a few of the problems associated with running turbos, its no wonder why they aren't more popular.

The only way to do it with least chance of hurting parts. Costly but may be worth it.

There are two 460 twin turbo cars that I know of. They are both on the junkyard turbo e-mail list. The wagon and a fairmont. They used the turbocoupe T03 turbos with the .63 a/r housings. Which work okay but are still too small toprovide enough CFM for a 460. I am considering a twin turbo setup also. It would take a minimum of 2 t04's to feed it. I just so happen to have a new t04 sitting in my garage and only need one more. Fabricate a exhaust manifold and induction system and off you go. The only problem then is having a block that will withstand the kind of power it would be capable of.

205.188.199.167 Weak block?
No score for this post August 9 2001, 10:23 PM

What block problems are you referring to? I ran a stock 460 block [2 bolt main] and cast crank with a Gale Banks twin turbo/intercooled system and never had any problems with block, crank, rods [stock CJ type], bearings or oil pressure. The only things I did with the stock block was stud the mains and used ARP rod bolts. Do you know something about the blocks I should know?

Well I have been told that a stock 2 bolt block is only good for 750-850hp. And with twin turbo's 1000hp out of a 460 would not be hard to create. And a stock 2 bolt block would go boom.

198.81.17.48 Twin turbo stock block.....no problem
No score for this post August 13 2001, 8:49 PM

I ran a D2VE block from a Lincoln, only thing I did was stud the mains. 2 bolt block, cast crank, CJ/truck rods and TRW pistons [L2404F] Iron 92cc heads with big valves, never had any problems with the lower end, no cap walk, no bearing problems, no rod breakage but I did burn a few pistons getting the fuel system working properly. Ran the engine with up to 14-15 lbs of boost. The secret to long life in any engine no matter what horsepower level is to keep the engine from detonating. Otherwise your engine life can be measured in seconds, damn FEW seconds.

208.45.92.253 Don't think there is one big enough.
No score for this post August 13 2001, 2:39 PM

I went to the Turbo site of Ray Hall. He is the australian turbo guru. He has a link to a turbo calculator application that is determine what size turbo you should run on your engine. I plugged in a 460 and it replied with the 2 T04's at about 1000hp. The problem you run into with a single is having a turbine housing with a large enough a/r. I think the biggest I have seen is 1.30 a/r. That on a 460 would spool up quickly. WHich isn't all bad except that at higher rpms and boost levels it's pressure ratio would get ridiculously high and it would super heat the intake charge. In other words become very inefficient. With 2 T04's both with a 1.15 a/r you can avoid that problem.

63.26.4.138 Every day I see HUGE turbos on deisel applications...
No score for this post August 14 2001, 1:25 AM

Some would be way to big for a 460. The turbo off of a 3208 Caterpillar V8 looks big enough, and it has two exhaust inlets on opposite sides of the exhaust housing. For reference sake... a 3204 Cat L4 engine is exactly half the size of a 3208, and it uses a single TO4. So logic says that the 3208 turbo is twice the size of a TO4, but I'm not sure.
I might be able to find out though.

208.45.92.253 Deisel Turbos don't work for conventional apps.
No score for this post August 14 2001, 8:52 AM

They don't work well for this reason. A deisel engine only rpms to 2500rpm. Its turbine housing is small for quick spool up. Those turbos don't move allot of cfm either, they are meant to create boost quickly. They would not fit at all well to a conventional engine application, it would spool quickly, but at higher rpms in would just super heat the intake charge and not be very efficient.

198.81.16.57 No compressor seals
No score for this post August 14 2001, 11:49 AM

Alot of diesel turbos do not use compressor seals because these engines are not throttled in the air inlet and do not need seals. If you try to use these type of turbos the engine vacuume will suck oil from the turbo center section and into the engine. I don't need to tell you what happens then.

63.25.254.141 A 1000 cube deisel moves lots of air at 2500 rpm...
No score for this post August 14 2001, 7:47 PM

Probably as much air as a 450-500 inch gas engine does at 5000 rpm.
And deisel turbos ARE sealed because they would suck oil when the air-filters got clogged if they weren't.
They just use a smaller turbo per cubic inch than a gas-burner does.
I'm not a Turbo expert by any means, but I am curios enough now to look at some housing #'s and compare.
NDSP...What are the #'s on your TO4, I have a Cat TO4 right here in front of me for comparison.
I'm not trying to argue... I'm just curious.
Email me personally if you want.

Thanks

I'm no expert either, just repeating some things i've heard and come to think of it I should of maybe questioned more. A big turbo is a big turbo.

I'll get the number off of the turbo and post them up tomorrow.

Here is a pic of it. It is fresh, may be brand new I don't know. The guy I bought it from didn't know allot about it. But the turbine housing is brand new 1.15a/r. It still needs a flange welded to it.

Banks used mostly Rajays, at least the systems I've seen. Mine are 370E with 1.0 A/R exhaust housings. No wastegates are used yet. Some of the other turbos he used were 300, 301 series turbos.
