how much power where you making staylor? boost by gear set up?

 

This was 15 psi about 450 whp boost by gear was not set up because I switched to a 4 port boost controller. I do drive the car hard the cc stage 4 doesn't help any either, I floored it already rolling in first banged second then boom. It still drove fine just had no second I had a spare ap2 so just swapped it out the next weekend. I haven't been banging gears since I replaced it, I try to shift slow and smooth now.

 

Just wanted to get an insight on things before building my S2000. but lets say the goal is to make 700 whp on a built f20c turbocharged and upgraded diff. Im not gonna launch the car from a dig just roll races every now and then other than that it'll be a daily. would I be able to get away with the stock transmission holding up for quite awhile or should i just upgrade it to something else ?
