Install a Positive Displacement Blower on your S550 Mustang (2015-2023)

As the leading Ford remote tuning experts Lund Racing has tuned thousands of S550 Coyotes (2015-2023 Ford Mustangs) with various Positive Displacement Supercharger kits. As we've continued to compile data, sharpen our tunes, increase their performance, one thing we continue to notice is that the public consumers may not have all the data needed to make the leap from their existing N/A setup to their desired PD Blower kit. In an effort to continue to educate & empower the consumer public, we wanted to give you guys the outlook from our perspective as to what you need to make that jump trouble-free! 

For starters, we don't ever suggest making the investment into very many mods while enjoying the car in its N/A capacity. If you're planning on running a PD Blower, like the Whipple, Roush or Edelbrock, then we only recommend a handful of mods to be done while you're Naturally Aspirated (N/A). Let's go over those here, quickly:

-Longtube Headers
-Free Flowing Exhaust
-Drop-in Filter -OR- PMAS CAI
     Gen 2: PMAS CAI
     Gen 3: PMAS CAI
-Lund Racing 93 Octane / E85 Tunes

That's it. Literally. That's all you need to do while the vehicle is N/A to enjoy it! Save all the other (read: mostly useless) mods and save those pennies and invest them into your favorite PD Blower Kit! 

Most of the aftermarket products rely on Marketing Hype, inflated Dyno Numbers, false promises, skewed data, and so much more - all of which is just built in to generate SALES for the company. The fact remains that there are very few vendors or manufacturers who are actively pursuing perfection, implementation with other existing products in the marketplace, perfect drivability, perfect MAF signals, so on and so forth. With that being said, we've busted so many marketing hype myths here at Lund Racing over the years, that we know what works, what doesn't work, and we can show you the difference in the datalogs. Most of the time, the only reason your car is going any faster with these mods is because your wallet is lighter on the next pass you make. 

Now with your handful of N/A mods purchased & installed, knowing that you're planning to go with a positive displacement blower, let's start down the path of picking your blower's accompanying mods! 

You'll want to get at least a set of 55lb Injectors (OEM Predator), but we recommend ID1050X Injectors. For pump gas setups, you'll need to at least have a Boost-A-Pump, as well. You'll need to grab a set of NGK6510s and gap those down to about .026"-.028" gap. You'll need to purchase & install the Brass IAT2 Sensor & Breakout Harness from VMP. You may want to go ahead and purchase a UPR Dual VTA Catch Can System to relieve the engine of the increased positive crankcase pressure. That should cover the base setup that you'll need to get started!

-55lbs (93) or ID1050X Injectors (if E85)
-BAP (93) or Return Fuel System (if E85)
-NGK 6510s at .026"-.028" Gap
-VMP Brass IAT2 Sensor & Breakout Harness
-UPR Dual VTA Catch Can Kit
-Lund Racing Boosted Tune / Tune Revision (+$500 for Existing Customer)

From here, you're basically left with needing to decide which Supercharger Kit & which Supercharger Pulley you're going to want to run. We've compiled a list of Pulleys / Boost / Octane, which may vary a bit from what the Manufacturer states on their website(s), yet it is accurate based on thousands of datalogs reviewed.

Take a look at the various Lund Racing PD Blower Boost Chart's below to determine what pulley you can run based on your selection of supercharger & your existing fueling mods:

Our Boost Chart is based off of using a stock lower crank pulley size (not overdriven). We typically treat a Gen VI blower as +1-1.5psi over the Gen V boost ratings. In general, the 3.8L Gen V will add 5-6psi over the Gen V boost ratings. Properly Ported blowers can expect to see as much as another 4psi, as well. If a lower pulley is involved, take the Overdrive % from the pulley and multiply that by the boost # to get the new boost range w/the Overdriven Lower included in the combo (for instance: a 10% Overdriven Lower with a 16psi Upper Pulley is going to increase boost by 1.6psi for a new output of ~17.6psi; you need to take account for this when picking your pulley combo(s) and comparing against your existing or required fueling upgrades. Once you get to the 3.0" Pulleys, and smaller these require the race variant(s) of their respective fuel(s).

If you're working with one of the older Whipple Supercharger kits, like a 2.3L or a 2.9L rear feed units, here's our boost chart for those products as well. We went ahead and included the 2.9L front feed units in this chart as well. 

Another very popular, powerful & reliable PD Blower is the Gen 1 & Gen 2 Roush line of TVS Superchargers. You'll notice that sentence did not include the Gen 3 Roush Blowers, and this is for good reason. We do not support the 2018+ Coyote Roush Supercharger in any fashion, on any platform, as the product is simply inferior to other items in the marketplace and will cause our enthusiast customers more problems & headaches than what we're willing to put them through. Roush really missed the boat with their Gen 3 product, sadly. As soon as we start putting power to those units, the IATs increase at such a rate that there's simply no good reason for us to support them and watch our customers blow up their cars from super high IATs, Misfires, etc. Our customers will be best served with replacing any Gen 3 Roush blower with *any* other boost combination. The below boost chart will apply to Gen 1 and Gen 2 Roush & VMP 2.3L TVS Head Units: 
 

These Gen 1 & Gen 2 Roush & VMP PD Blowers are also available in a 2650 TVS configuration, and there are slight differences in the larger Head Units and their boost output. The below boost chart has taken that into consideration for those of you wanting to run a 2650 TVS Blower: 
 

Another PD Blower that is very well done & a well-vetted combo, is the Edelbrock E-Force Supercharger. This kit comes in both a Stage 1 and Stage 2, with either a 6-rib or an 8-rib pulley combo. Most of our customers that are really looking to get after it are utilizing the 8-rib setup & we've seen them make 20+ psi in that configuration. 


 

As always, our intention is to continue to provide data driven results to you, our beloved customers & supporters. These combos are an affordable, well-vetted, provide repeatable & predictable results, with seemingly great reliability & customer support from their respective Manufacturer(s). Hard to beat that!

*Editor's Note: Please remember that not all combos are the same, not all setups are put together leak free, not all fuels in all geographic locations will be the same. Our suggestions and recommendations in this tech article are for reference & your exact combo may vary. We will review each specific combo at the time of ordering, as well as reviewing each vehicle's individual datalog(s) for verification of safety & performance, regardless of our suggestions/info on the boost charts provided.
