I dont get what you people have over quick spool time.. Having a later spool allows your torque to come in later which given there are 3rd gears shitting the bed with just the 6758, having less trans-destroying and tire-scorching torque at sub-3500 RPM would be REALLY beneficial.. as long as your in your powerband, there's no such thing as "lag", that and like stated above, slower spool down low normally gives more power clearance up top... seems like a win-win there

The 6758 EFR flows 53lbs/min and the 7163efr flows 60lbs/min I can't wait for this

Been thinking about going with the treadstone stg4 with gtx3582r. I know I can't push that turbo and it will be in nice efficiency range. Don't really think this will be out this yr

I guess they are waiting on the exhaust housing from borg warner is what they said to me in email.
I have money ready to blow on a ZFR, wanted to be cruising around at TX2K14 with a better turbo, so not sure if i should wait, it could take a long time to develop.
Anybody else have any news?

Yea I hear ya. I'm getting my meth pump next week so I'll get to finalize my tune so I'll enjoy it for a week or 2 before being bored again. I'm just happy it holds boost to redline now instead of dropping off like the stock K04 I like reving it out

It depends on how fast it spools. It's can't possibly hit peak torque as fast as the 6758 does

Ya same I was gonna guess 200-300 slower but it'll still be fast enough for a daily. Oh ya great numbers! Do you have springs but stock cams?
