13B-REW came in with the dreaded low compression from warped apex seals on a another shops "tune". We rebuilt it with some extra strengthing mods new seals and she's back to running smooth as silk 🀌.. We also replaced the stock crusty engine harness with a Rywire 13b engine/ ignition harness. Were going to get it back to the owner on our low boost break in tune first. Then back for more hp's and pounds per square inch on the turbo after break in. We'll get some dyno videos shortly stay with us!

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 πŸ˜…. Thanks Zak for pretty much giving us free reign to do what we wanted on his awesome FD. 🀝

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 πŸ™ƒ. We'll be back at it soon with a higher flowing pump and some more pounds per square inch of boost pressure πŸ˜‰
