The blowing up of twins at over 1 bar rumor has been proved to be wrong for years now. I know you're having fun with the BMW, but get with the times 
If your going to spit the turbine blades out the muffler, its going to happen no matter what boost you run at, it's a fact of life with 15 year old ceramic blades.

I didnt say you were right or wrong..... I wasnt even talking about cars... You must have interpeted my comment wrong.
You of all people should know my car was always at 1 bar or more....

yea it was from a dig .Im auto ,he is 5 speed i doubt i would be able to hang with him on the highway tho.the stock twins dont build any boost after 85 mph or so .But the stock twins can be boosted past 14 psi all day for those who have doubts about it and will pull harder out the whole than any single setup imo

I seen set ups of a number of guys running 400-450whp on 18-20psi through a 61mm dual ball bearing turbo that makes full boost comfortably before 4k. But, a 57mm on 18psi would give you absurd spool and enough flow to get you deep into the 3xx range.

Although I know someone that is pulling 270wkw (approx. 360whp) and was aiming to pull a 12sec 1/4mile until he twisted the tailshaft (JZ motors = torque monsters 
)Go for a big single with supporting essentials.
