what to expect with different turbo
so right now i have the edge jammer bb turbo. i have no complaints about the turbo at all if you need the size its a T-58 compressor ( 58.4 mm inducer) with a 68mm 10blade Q-trim turbine. The turbine housing is .84 A/R something like a 15cm 4" V-Band
Its non-wastegated. i want to go up to a 64/13/71 or a silver 62. how much more laggy will the 64 be then the 58? will my egts drop a lot with the 71mm housing then with the 68? and how about boost numbers will i see more boost or less i see 40psi right now with my current fueling. or my other option is making a twin set up with the jammer i just dont know witch will be a better rout. and i only tow a 2000 pound jet ski so towing isnt a concern.

shouldn't be too bad. I have a buddy thats running DDP's 62/14/74 non wastegated and it spools great! He is running DDP 75 hp sticks, Edge juice and a smarty for fueling and can push 46+ psi boost. A 58mm charger is way to small for any kind of performance and i'm sure you are out of that chargers efficiency range

yea i think with my set up i am at the peak of this turbo. i want to do a wastegate if i do a new turbo. do you think if i got the drag unlock and a smarty i would be able to spin a silver bullet as a daily driver?

What are you doing with this truck? Do you do lots of WOT runs? The SB turbo has lots of top end pull, but is lazy on the bottom end. If you are doing it as a daily driver, I'd stick to a 62mm turbo, or look closer at twins. I have a 62 on my 12v, and my truck with the stock turbo was more fun to drive around in the city. On the highways, the 62 is more fun.

thanks tate. i drive through curvy roads a lot so letting off and getting back on it and having turbo lag will get annoying. how do you like your silver bullet? do you think a silver 62 would be a good choice? or a super b single? isnt the sb a little small on the hot side? would it be better putting a s475 under my jammer? sorry for all the random questions im just getting the fever to do something new to the truck. lol

Going bigger in compressors is the thing that slows spool the most ime. Makes sense because that is the working portion of the turbo. The super b special has a 71 turbine and the silverbullet has a clipped 74 turbine. The bigger turbine will mean that when the turbo does light, it'll light hard. It also means the turbo will move more air out the exhaust at full boost. The housing should be of simular size, but the large wastegates on those housings should flow a lot of heat around the turbine at full boost. Both of these should lead to lower egts at full boost.

I don't know about how well the drag comp will stack with the Smarty but if it is anything like the level 6(hot) on the Juice, it and the smarty don't get along well and hurt performance. If you are looking to upgrade your electronic fueling a Quad Adrenaline with the pulse controller/Smarty stack would be awesome. Industrial Injection has a great turbo line up. I worldn't run the Jammer in a twin setup. A SPS 62 or Silver 62 with a S480 or Garrett 4202 in a twins setup would be awesome and have good spool up. But it all depends on what your final goal for the truck is.
How much power are you looking to get out of your truck?

i have a goal of 550. anything close will do. if any of you have extra time on your hands check out one of the jammer threads the title with the twins set up i want to run is edge bb turbo?? posted by juicedbusa02 and the guy running the twins set up is 13fox. he is running his set up on a 12v so i dont know how it would work on mine in comparison.

I would put a S475 with a 1.10 a/r on the bottom using the the edge bb as your secondary. It should spool rather well and have no problem reaching your goal of 550 with the right fueling setup with decent egt control.

No need to go to a S480 for 550 hp. A k31 would be plenty, and with it being internally wastegated, nicer to tune. Failing that, I would look at a S475, or a GT4202. BW turbos supposedly flow more for the same size compressor as a Garrett, but the Garretts can be had in ball bearing trim, so spool will be quicker. For 550hp, I would do the latter and have a quick spooling setup. I can't remember if 13fox has a ported head or not. If he doesn't, then the 24v will start boosting earlier. My 12v spooled the stock turbo similar to my 24v with the 62mm.
One thing I would reccomend if you do twin with your bb turbo, is get an external wastegate for it. Easier to keep max boost down, and you won't be choking the exhaust through your housing.

If your gonna use the edge BB turbo use a larger external wastegate (42mm+). You gonna restrict top end power with that turbo, but at 550rwhp, the truck is just starting pull some boost 50-60psi. You could put a S366 under that turbo and have a wicked fast spooling twins. Use a 42+mm external gate, so you can wake up the S366 turbo. I bet that the GT4202 is one sweat single turbo. I'm still working on Tate to try it as a big single.![Laughing](https://www.dieseltruckresource.com/forums/images/smilies/laughing.gif)
58mm inducer is pretty small for any real top end power in twins. The K-31 would be another nice twin for that turbo but use a external gate.
