    The Explorer ST Engine Build Begins!

    I don't want to do any head porting yet. I think the porting that has been done in the past has been in effective/hurt the performance. I am looking into what can be done on the exhaust manifold side though, I have a pretty good plane there.

    The Explorer ST Engine Build Begins!

    Well here you have it! The first sets of production connecting rods have made it to ZFGR. I'm not going to lie to you guys, these have been a thorn in my side for years! We started the "built engine" project in 2021, and fit the first 3d printed prototype connecting rod in September of 2021...

    ZFG Launch Strategy

    Totally different ball game these days. As long as you don't over heat your transmission you're good to go. It's also the only way to launch. Sent from my SM-S918U1 using Tapatalk

    You definitely want to stick with OEM fluid and yeah 60,000 miles is getting to that point. The procedure to check the fluid sucks! That's because it's not supposed to have to be checked but clearly it is an issue, and to be honest I hear of a lot of brand new ones that come off a quart low...

    List of common mistakes and issues when increasing performance on Explorer ST platform

    Why would you trust AutoZone's website? [emoji38] They are not listed as compatible because they are not stock replacements they are one heat range colder than stock. Sent from my SM-S918U1 using Tapatalk

    Any Stage 3 upgrades known yet? COBB said they aren't doing it yet.

    Right? What exactly are they waiting for. There's a proven recipe out there for 650 all wheel horsepower and everything in between.... why would you wait for a company that's 4 years behind and only getting into it because we (the Community not just me) made it cool Sent from my SM-S918U1 using...

    ZFG Launch Strategy

    I'm seeing a trend in data logs so I want to revisit the launch strategy (not the trans brake) . All new tunes have the launch strategy update. To use it do the following -pump the brakes -push brake pedal all the to the floor -go directly to 100% pedal position It's important that you don't...

    List of common mistakes and issues when increasing performance on Explorer ST platform

    Time for a new pinned post so we can get rid of some others! Here is a list of common mistakes and issues found on this platform! Oil pressure drop. If your engine is low on oil, you will experience an oil pressure drop on a hard launch. The lower the oil the worse the drop is the longer it...
