Honestly, I am not 100% sure.. it seems getting these to 300psi isn't super hard... but no idea where he gets the 100+ psi from.
He has no trans cooler. Or at least conventional one that I know of. The stock in/out lines on the bottom of trans just loops to itself. Not sure
if that assists in removing many feet of line. Either hogged stuff out, stiffer springs, and other unknown valve body tricks, or external electrical pump to boost it?
With my trans build at TEP dave said it should easily be 300psi or so... and that with the new converter setup, there is no need for 400+ ... so hopefully that works out.
With some of the stuff dave is doing, and some "secret" things he's got going on, the trans build should take 8's without a problem.. Just need a motor behind it to push
it that far. Getting well into the 9s is my only goal currently.
