  1. 2015-17 Mustang GT Ford Performance Power Packs

    Yah there's a lot there, but everything has been very carefully and specifically chosen and tested. Most of the upgrades have been incrementally performed, so the differences are notable. Drive ability is close to stock in terms of comfort and NVH characteristics, there are of course some minor...
  2. 2015-17 Mustang GT Ford Performance Power Packs

    The Ultimate Street / HPDE Dual Purpose Setup in my opinion is as follows: 1. Power Pack 1, 2 or 3 - these are the best over all ECU calibrations for the 5.0 from both a reliability and drive ability perspective. They also produce power that is competitive with non-warranties and non emissions...
  3. Anyone changed there oil to 5w30 and encounter a problem, failure or any weird noises?

    Takeaways: 5W-20 or 5W-30 for street, Auto x, drag or light track use. Also ideal for extended HPDE sessions WITH an Air to Oil cooler. 5W-50 for extended HPDE track sessions on the stock cooling system. Oil temps in the 270F and up to 300F range are common. So a 50 weight will thin out to 30...
  4. Which Oil Filter? FL-500S or FRPP FL-820?

    It's a good filter. It's probably the best balance of overall function of any filter out there for Ford modular V8 applications. Most of the other options have some big trade offs and honestly they aren't design for track type use. They are more intended for street use. For track / high...
  5. Anyone changed there oil to 5w30 and encounter a problem, failure or any weird noises?

    A3/B4 would provide similar bearing protection to SAE 50 or 60 weight (HTHS of 3.7). But the question remains, can they provide a lower viscosity at 100C than 50 or 60 weight? Those grades have substantially increased drag in the valve train during normal use as they are in the 16 to 21 cSt...
  6. Which Oil Filter? FL-500S or FRPP FL-820?

    I mean the direct fit OE replacements from M1, Amsoil, Wix etc. Aka their versions of the FL-500S you would find when finding a cross reference. Hopefully that makes sense.
  7. 2015-17 Mustang GT Ford Performance Power Packs

    Just wanted to add that the Velossa Tech Big Mouth works well with GT350 Air Box. I felt like mine was being starved for air at higher speeds 80-130 mph range. Factory ducting isn't designed specifically for feeding air at high speeds. It's designed to block debris for longer filter life and...
  8. Which Oil Filter? FL-500S or FRPP FL-820?

    See the M-6731-FL820 spec straight from Ford Performance for your viewing pleasure. Just for reference the surface area given for the FP FL820 is actually 283 square inches, not 250. And it's rated for 99% efficiency at 20 microns multi-pass. According to Ford Performance it out performs the...
  9. Anyone changed there oil to 5w30 and encounter a problem, failure or any weird noises?

    I have a 2015 to 2018 Ford Mustang shop manual (digital form, 173 MB) that says the connecting rod bearing-to-crankshaft clearance is 0.0011 to 0.0027 for the 5.0L. 0.0011 to 0.0020 for the Ecoboost 2.3L and 0.0008 to 0.0021 for the Duratec 3.7L V6. 2nd Generation Coyote 5.0 uses Boss 302 crank...
