Tow/ compound setup

Just stroken · Apr 28, 2014

Well getting ideas an really interested In doing compounds on my 7.3. Wondering what would be the best turbos for a good daily Tow setup and injector size? I am currently running running a elite drop in turbo bout the same size as Garrett 38r and 250/100s fuel system n terminator any info would be greatly appreciated

Gate your elite turbo and add a gt45.

GT47 and a 38r was one of the best setups I've seen, factory mount/ up pipes, and seemed to handle a wide range of injectors very well.

Always wanted to do this some day, but probably never will.

Do you have any pictures? The intermediate turbine pipe would be interesting.

Why are you wanting to go to compounds? Your setup should be good for just about any situation.

Didnt Charles run that in his reg cab for a while?

I believe that's what he ran up until he put the GT55 on. Pretty much seems to be the benchmark of compound 7.3s.

Yes, if I remember correctly. One of the nicest running street driven compound turbo 7.3's I've seen, to this day.

Has anyone run the GT47 or similar turbo with s300 series or smaller frame t4 mount turbo in a compound setup? I'm thinking long term I would like to do this once I secure a decent forged rod block. Initially I'm thinking of starting with the Bell BASB which should have similar characteristics as the 38r but with different mount. Sorry about the high jack.

I don't think forged rods like the tq curve responsive compounds are capable of....maybe make sure your fuel is turned way back with your tuner to be sure.

Have you tried this yet to get a ballpark idea for sizing vs rpm vs power goal vs altitude?

They have some great whitepapers on their site. Thanks for recommending the app. Will plug everything in when I have a chance. I was thinking the same thing about being conservative with the fueling on the bottom end so as not to stress the rods too much. Throttle response is the real advantage I see with this setup, just can't be too overzealous with the fueling down low.

Id say correct to that. IIRC a member here Maddiesel73 windowed his forged rod block w/ twins on the 7.3. I understood it that it was a blast and super responsive but ka-bluwie. http://powerstrokearmy.com/forums/showthread.php?t=20131

I'd consider twins w/ forged aftermarket rods however, the procharged 7.3s that were floating around, were they on stock FMR or aftermarket? I'd be curious to know.

Yes....BUT, iirc, when he switched to the 55, the difference in exhaust wheels made the setup much better over the 47.

Think long and hard to go to twins, that's a lot of stuff under the hood to deal with if it needs to be worked on.
