So looking for opinions, I have 17t's now installed and going to tune it to about 24-26 psi. I wanted to use an 8hp70x but I'm still not able to find info out there on what adapter there is for the 535. Plenty of 335's out there but not many e60 535. So if it's not available what option do I have other than an 8hp45x a d how much torque have you guys seen it hold long term? I was hoping there would be some options . Maybe someone has the measurements of the 6hp21x and there is something I can do having a company fab it up. Or with xhp will the 45 be OK? Thoughts?
