Still on the stock bottom end and we haven't maxed the blower out yet.
Man, that is nasty!! Very nice OP!
Hold long will the stock internals and bottom end hold out for?
Thanks for taking the time to test the new blower setup and posting results. I'm about to max out the d1sc on my 2012 GT and was very curious about the d1x. I'd rather keep a smaller blower with less stress on the crank if possible.
I read your thread over on LS1 tech and I just want to confirm a few things.
Were the same pulleys used on the dyno graph overlay where the d1sc was making 16psi and the d1x making 18.5?
What blower speeds were you seeing with both head units?
The d1x and d1sc are rated for 62,000rpm impeller speeds but you said the max is actually higher than that. Do you know if the d1x is good for 65,000, 68,000, 70,000 ect?
