How much boost have people applied to the 460? I am only thinking a max of 8psi on the stock short block. This is okay on a 5L block so a 460 should be more that able to handle it. Ya or na?

Has anybody ever heard of somebody using any type of forced induction on their big blocks? I did a quick search of the site and only came up with the regular turbo deisel stuff which doesn't help.

How does the 460 run without its smog pump equiptment. It would simplify matters 10 fold on the passenger side to remove that entire system from the vehicle. The truck already has an aftermarked Banks exhaust with no cats (the exhaust would be scrapped after anyways) it does not seem to cause any problems with the fuel injected computer. The theoretical exhaust routing passes right through a lot of that stuff. And its not as critical as the turbochargers so it would be nice to move that instead.

Also this goes back to the power handling of the driveterrain. Has anybody thrown a shot of nitros at one of these babies? If so how did it hold up?


Not sure if anybody can help me out with this one. But I have been able to somewhat visualize the routing of exhaust, compressed lines, a large intercooler. If anybody has seen something like this done please send me in that direction. A discription a link to any forced indution truck running fuel injection would also be able to help me out.



Thanks for any help you guys can give,

I cant help you out on the turbo parts, but did you know that vortech makes a supercharger kit just for the 88-97 460's. It would probably be much easier than making all your custom turbo stuff.
What kind of tranny does this truck have?

 

Second the supercharger, Just way easier! Less to go wrong.

 

Tranmition is a 5 speed standard.

I like the trubochagers better. You can set them up to change the boost inside the cab with adjustable wastegates.

Most of the fabrication is just welding exhaust tubing.

Tig welding up the endtanks.

And relocating wires.

 

There is a 460TT buildup in a Fairmont on this site. http://www.toohighpsi.com
Here is another good site for turbocharging Fords http://www.turbomustangs.com
I'm going to start a turbo 460 in a month or two when I get my other car done. It's going to be a stock long block with a Edelbrock Performer intake and a Holley 850 DP modified for forced induction. The turbos will be a pair of Buick Grand National Turbos used in 86-87. I remember an article about a guy who built a stock smog 460 and put a pair of T3 turbos on it. IIRC it was putting down around 350hp and 700 ft. lbs. of torque! The turbos were too small so it was all over early but it would still make a nice stump puller

 

As far as I am concerned,Turbo is the only way to go!!!
Turbo is free horsepower. A supercharger robs power off the top to drive it.

I would think that a 460 has plenty of room to grow!!

I would go with the turbo also. But if I were the one doing it I would have two turbos. One small one to get you off the line and a larger one to give you high end.

 

JJ thats the way the big hp cummins guys are doing it . Maddog making someting like a 1000hp and 2000ftlbs .His truck is 97 f350crew cab long bed 4X4 and it runs 11.40 1/4s on #2 only

 

Where is my moron smiley? Of all things no HP is free.

Free HP is a urban legand. Ricer Myth and amongst other things illogical.

Turobchargers and superchargers both put restrictions on engine power.

Superchargers borrow power from the crankshaft and use that to compress the air allowing more air to be pushed into the cylinders.

Turbochargers also put restrictions on engine power. Why increased back pressure on the exhaust hurts engine performance. The free HP is a myth.

 

Sequential turbocharging is okay but a properly sized turbocharger(s) would be a little better suited for regular driving.

 

Ok, as far as boost goes, you *should* be okay with low boost but the stock cast pistons are not the best for forced induction. Obviously forged would be better but cast will work as long as you avoid detonation. That can make your pistons go in short order if things aren't tuned right.
