Solid 513rwhp..Fuel pressure issues resolved, installed a 465lph fuel pump. Finally we can get a decent safe tune in on Zac Se7enS beast FD. 93 octane with a sprinkle 🤌 of AEM Electronics water/meth injection, Haltech , 21-22 psi on the turbo. Engine we built/ ported around 5 years ago here at Phalanx still strong as can be! Now to address the brakes 😅. Thanks Zak for pretty much giving us free reign to do what we wanted on his awesome FD. 🤝

Can someone help Mr.Rad to upgrade that overflow? 😉 This rx8 is too nice! And makes some smooth rotary power💪

Mr. RADS Rx8 here at Phalanx for some 20+ psi pulls. Check it out!

Buzz is ripping good boys! Had a special visit once again from Mr. RAD and his turbo Rx8s 😎 I won't spoil the hp numbers before he gets the videos out, but we had a great time as usual!

FD getting tuned up on our in house dyno going for 500 rwhp on pump gas and wtr/meth as a safety. We got close, and had to shut it down early in the rpms due to lack of fuel pressure 🙃. We'll be back at it soon with a higher flowing pump and some more pounds per square inch of boost pressure 😉
