Power is power at the end of the day. The BC 'box is rated to around 150lb/ft AFAIK and whether you have the power by way of high comp/low boost or low comp/high boost, if it has the power, it will break the gearbox.
I upgraded to IB5's several years ago and have spanked alot of those too.
i bet your box lets go at peak torque low'ish revs in 3rd gear ?
i find that just giving it death from 1st off the line right through the gears there ok but if you plant it at 40mph in 3rd it breaks.
what is your top speed goal? i thought it was 170 but you did that last year.
