    I was wondering how high a 4r70w can be built to shift n/a? Only looking for 6500-7000 if possible.

    Your sig says your car is all stock right now, why would you want to shit at 6500-7000 at all?

    well thats true if you have a stock car. at 6500 or 7000 its probably maken as much power as it would at 500 rpm. If its npi then you won't make power over 4500. Pi then it goes to about 5500 where the stock shift locations is :) much better in my mind.

    I'm trying to figure out exactly what i need to do to this to make it live with what i plan on doing. I wasn't planning on trying to spin this motor this high, it's for the next one. If an auto won't do it i will put a stick in it.

    I believe Jim Fitz (ModularPowerhouse) was shifting his in the 8000rpm area but has switched to a race tranny now that he no longer daily drives it...He has a 2.8KB'd 2V in the 9's.

    they make just as much boost at 8k as they do any rpm lower. just because they aren't constantly accelerating and building boost through high rpms, doesn't mean they dont make high rpm power.

    yea i'm not douting that, i'm just wondering what kinda cam that things got in it to make a 2v rev and make power to 8k. Putting that car into the 9's is a great thing, just don't see many k/b's running in the 9's ya know.

    Its a set of custom cams from Tim @ MPH i'm sure, Jims car is sponsored by MPH...i also think Tims son's car which also has the 2.8 KB is in the 9's...As far as i know those are the only 2 2.8KB's made for 2V's and no more will be made. Lucky MoFo's...
