Worlds Fastest & Only 5 second Coyote
MMR is pleased to release its CNC head porting to the public. MMR's Port design is over 3 years in the making and holds every Ford Coyote Record including Worlds Fastest Ford Coyote with an astounding 5.67 1/4 mile @ over 265mph and producing over 4000hp with factory cylinder heads!

Let MMR take your 2020 GT500 cylinder heads to the next level with CNC porting.

When you send MMR your GT500 cylinder heads we will fully CNC port both the intake and exhaust ports to our most recent specs. Flow is greatly increased over all stages and our port designs are both dyno and track proven. HP and TRQ are both greatly increased with zero sacrifice in reliability or performance!

Finally the combustion chamber is reshaped to unshroud the valves and spark plug for reduced chance of detonation and increased cylinder head performance.

Valves are pressure tested and lapped as needed prior to reassembly to ensure a perfect seal.

Price is per pair

Notice the part number says cnc350. Have you actually done this on a 500? Results from testing? Videos?

I see there site has GT500 specific part numbers. But would be overall curious there porting between regular coyote, gt350, gt500 variations, similarities, and differences both physically and conceptually because of NA, Flat plane and force induction. If those even come into play or if flow is flow.

This was a typo and been corrected. The HP #'s we have published are conservative #'s, the low #'s represent the lowest #'s we have seen during our dyno testing and are VERY representative of the minimum #'s that our customers will see. This dyno testing and our Race Teams World Record proven track performance are a true indication of our results and dedication to making real hp - after all, HP on paper doesnt set world records! We will be gradually updating the website to include these results including some videos so stay tuned and thank you for your interest!

Cool. For a second there, I though you might be the type to make up a product before it exists or has been tested.

2014 GT500 and a few others
Please clarify this.
The 2020 GT500 has heads with CNC porting that has been increased over the GT350.
Can you post some before and after data on real 2020 GT500 heads?
I’m starting a turbo Coyote project and planned to start with stock GT500 heads.
If I can see the flow data on the new 500 heads stock and ported, I may opt for this service from you.
