Agreed, details/discussion on transmission mods necessary at these power levels would be appreciated.
Member on another forum with a Supra said he had to have transmission clutches upgraded at these power levels - an 8K cost including labor.
That's a big consideration, IMO, but yeah maybe BMW xDrive makes a difference?
Also, any general consensus/ballpark crank HP numbers at different stages of upgrades with the BMW B58 xDrive cars?
Stock - 450 crank hp?
Stage 1 (93 oct ECU tune) - 550 crank hp
Stage 2 (93 oct tune w/ DP, intake, etc) - 600 crank hp
Stage 3 (hybrid turbo + bolt ons) - 700 crank hp 93 oct/~800 crank hp e85?
Sorry, a lot of numbers/dynos/timeslips/mod lists are thrown around, just trying to sort through it all...
