Wow today was a long day!! We had tons of problems with T-bolt clamps and boost leaks, throttle body coupler blowing off boost tube several times, ect ect. End results were good but man if fought every step of the way.
One point I wanted to make, the TurboXS MAF housing I used for the blow-through at 66mm ID WAS to small (you know who you are that told me). Good thing I brought my extra 3” OD pipe I used when I went blow-through with a 73mm ID. We cut off the MAF housing and welding it onto the new pipe and it worked like a charm!
Going FMIC on the VF52 I must say is a must do!! We changed everything you see in RED and marked NEW so im sure it all helped but as you see we produced ZERO LAG!! And even moved the power curve ever so slightly to the left. Again lots of things changed but from the pics you can see the new RED line torque and power curve never touched the old blue lines!
Best of the day we made 318HP targeting 20psi tapering to 14.5psi and 366TQ. However they just weren’t as smooth as Eric would like them to be so be backed things down ever so slightly and made the lines a lot smoother and ended up at 313HP targeting 19.5psi tapering to 14.5psi and 357TQ.
Over all we made power everywhere! 21HP and 49TQ.
