I currently have your gen 2 tvs with 2.4" pulley, 127mm cai, and o/r xpipe. Will be purchasing your triple pass h/e soon. Is here a certain oil / viscosity you recommend? I have always bought Mobil 1 5w50.
We use Motorcraft 5 w 50 full synth (factory fill) in all of our GT500s. Mine, specifically, has over 56k on the clock with LOTS of abuse. Makes 750+ at the wheels and as of a week ago was still within 10% cyl to cyl at around 180 psi when we did a compression check.
