Need more sound!!!!!

Ok well my buddies went crazy with their 6.0s lately running non-vgt setups etc. they dont use there trucks for work. they are play toys basically and they dont use them besides driving around and drag strip/sled pulling. well they are prolly getting ready to pass me and i believe one of them already has lol so I gotta do something about it. talking to a few people about this including matt robinson at gearhead. Id like to do a single turbo kit running billet s366 that way it would spool decently and once it lights it will get the job done. plus with the t4 mount there is room to grow down the road. pros- simplicity, sound, ease of working under the hood, slightly less drive pressure. cons- lag, have to change driving habits, wont handle heavy loads as well, slightly higher EGT's.

My question is there any drop in atmo turbos that will give me some more sound out of this thing without swapping in new manifolds and all that right now. Also i know high powers sound awesome lol but not in my price range. I have MCC unlock running my own tune with VGT off at idle for that deeper sound. it sounds awesome now but wanted to do a little more power. studs and tranny im sure will follow but for now we will just run her till we got problems lol.

I drive the truck almost daily. haul 2-3k frequently not much more than that though and the truck is a tad lighter already being a short wheel base truck. let me know what ya guys got in mind. if i got single i will be using H&S single turbo kit and will be ready on the 12th. might do ported intake manifold as well just depends. truck also has flo pro elbow with all the IC piping as well.

thanks for your time

The reason the exhaust sounds like it does currently is due to the stock VGT and journal bearing low pressure. The reason Elite's compound setups sound so cool while still utilizing a "stock" VGT turbo is due to the low pressure turbo being a Precision ceramic ball bearing turbo. Something about the exhaust side of their turbos makes them sound so wicked. The modified stock low pressure turbos aren't going to sound much different. Slightly deeper tone and a little more whistle, but not a big enough change to be satisfied solely with the sound.

If you're after sound, I think an s366 or an s467fmw would be the best route to go. You'll make more power than you currently have and will still see decent spool up with proper tuning.

I personally believe in performance and drivability over sound, but it's not my truck.

Not to take away from your thread Travis, but this question has been eating at me for a while (and it's turbo related). All $ equal, would you pick a 71, 75 or 76 atmo while keeping the stock VGT? What kind of power/sound/driveability differences would you see with these?

If I owned another 6.4, it would have RCD's 75 or Elite's 76 on it. Instant spool up and you're talking 675ish on stock fuel with a race tune. I thought my old truck with Elite's 71 sounded throatier at WOT than a stock turbo 6.4 and when I added No Limit's cold air intake it sounded good in the cab. Decent amount of turbo whistle in the cab. Someone after dramatic sound change isn't going to be happy with drop-in turbos though. They're cheap and really effective though, which is why so many people are doing them. You can't beat the power gains and drivability aspects of them. Plus they're really reliable.

Sweet. Thanks for the info. I was kinda leaning towards the bigger turbos. Now to just narrow the 75 or 76. I'm kinda like you. I would rather function over form first. And power over sound. But it's always a nice bonus when they go hand in hand.

well that isnt the response i wanted to hear lol. I was hoping there was a magic atmosphere turbo that way i could keep the 100% drivability with out compromising. Guess i will just deal with this now and save my money. single kit may be asking too much. gonna hook my trailer to my buddies 6.0 with 175/75 and s366 and see what its like towing. it wont give me a perfect example but close

I think you'll really like it. If you go with it, definitely do a review. I know there are a couple of trucks in the Midwest that have made over 800 with RCD's 75/59 setup and fuel modifications. Should be a solid 675-700 on stock fuel.

I know MPD says they tow with their single turbo trucks without any issues. Tuning is going to play the biggest role in the drivability. There is enough fuel on tap stock to make 700 horsepower, so if that fuel is used properly with a 66mm single and the transmission tuning is spot on, you won't have any issues I don't think. Just don't expect it to ever pull a load like compounds with a VGT high pressure and you won't be disappointed.

being that the max this truck will tow is 2-3k i dont think it would be an issue but its hooked to that small utility trailer alot. idk i will see. i have some thinking to do. those with singles and gearhead tuning say its awesome. but the way gearhead is almost trying to force me to atmo drop in had me thinking twice. ive got time to think it over. either way i got to get the courage to rip them turbos out myself to save some money.
