Default MPD Quick Spool Budget kit

Anyone running one of these kits on a 11-14 with stock fuel? Im curious in hearing the pros and cons vs the standard S363 budget kit with stock fuel.

After talking with Mpd, No Limit, and Flynn shop, Iím between the S362sxe and the S363sxe. Iím just not sure which turbine would be best with the stock 12í injection pump. Obviously the 68 turbine will spool faster than the 74, I just want to make sure I wonít run into drive pressure issues with the 68. Iím running 35s with the 3.55 rear at sea level most of the time. Iím looking for the best spool for daily driving and towing. Iíve never had a non vgt so just trying to pick the best one the first time. Thanks in advance for any input.

Stock fuel 6.7 is enough fuel to get into the low 500 hp range.
I don’t have a 6.7, but I have done a bunch of non-vgt 6.0’s in that hp range. I really like an SXE 63/68/.83 or SXE 64.5/68/.83 at that power level for daily driving, some towing, and having fun. Drive pressure starts to climb fairly quickly over 3,200rpm on a setup like that, but that is a trade off for good drivability in the rpm range where we spend the majority of the time.
The 6.7 has a few more cubic inches, and better airflow capabilities (compared stock to stock) than a 6.0, so it is going to drive the turbo harder/ better/more efficiently.
If I were in your shoes, I think I would go with an SXE 63/68/.91.
Good tuning will definitely help.

So you think having the 63/68 in the .91 housing should keep drive pressure in check while still giving the best spool?How much slower would you think the 62/74/.91 would spool. Obviously with the 74 the drive pressure shouldnít be an issue. And realistically there isnít much of a power difference between the 62 and 63 since the 62 flows so much... I canít find info or videos for that matter of these chargers on 6.7 Powerstrokes. No real world numbers or in cab videos of spool up and normal driving. All sorts of info on Cummins but that does me very little good. Thank you for your insight.

What everyone calls a 62 actually measures 61.47mm, so the sizes are pretty evenly spaced. (61.47mm, 62.99mm, 64.4?mm)
Turbine size will make the biggest difference on spool up.
It takes 2 things to drive a turbo, heat and pressure. Ask yourself how much of the time you will spend at an rpm level that can cause back pressure to be high. The time you spend there will be minimal compared to the time you spend at lower rpm when daily driving and towing where spoolip will be WAY more important.
Most guys spend way too much time worrying about whether drive pressure will be 1/1. If you hit 1.5/1, or even a little more, at the top of a shift, or pulling a hill for a bit, ITíS NOT GOING TO HURT ANYTHING as long as egt, etc is within the safe zone.

That makes perfect sense! I couldnít tell you the last time I matted the go pedal. Which is sad cause I used to run the dragstrip all the time in my 6.0. Anyhow yeah you make perfect sense cause the truck gets up to speed plenty fast 2500rpm and under. Thank you Zeb for your insight.

I have a 2012 with an S363 but not sure if it is SXE. It is a 63/68 from Industrial though. I have stock fuel and TSD got 576 with a leak on the stand pipes so boost fell off around 27 lbs so might be around 580 since fixed and able to get 32 lbs. I've had mine on for around 50k miles with a lot of in town, highway, and towing 15k+ lbs and like it quite a bit. I have learned to drive around the shortcomings in low boost conditions and do just fine. EGTs have only hit 1400 on some 7% grades over 7,000 feet sea level, otherwise right around 900-1,000 towing heavy.

I’ve got a s363sxe on my ‘13 with stock fuel. I’ve been waiting for my tuner (a very well known guy) to revise my tunes for non-vgt. Haven’t gotten a reply from him in a month so I can’t give you a good review. It’s too bad my $$$ didn’t buy me any customer support....

I'm running the 364.5 SXE on my 2013 with stock fuel. It runs amazing, I'm super happy with it. Probably going to go 15+ CP4 this year and then it'll be done. Turbo spools great, can be smokey if I want it to be, but it's a lot of fun to drive. Night and day difference for sure.
