The OP wan't asking how to do it. He asked if anyone had seen a faster documented time other than the 151mph which was limited by horsepower. I can understand his asking not to bitch about safety because people fill up a thread making ignorant comments ruining what could be a good thread with useful info. Most of those guys have never seen track time or actually pushed the limits of a street car.
The OP was looking for documented times for BRZ/FRS like top speed or standing mile.
The op had his car 2 weeks before gutting interior to install a roll cage, doubling the horsepower, and upgrading suspension/tires. The reality factor is that with a few tweeks he has the perfect setup to break the BRZ top speed record. Hes not trying to break the standing mile world record. Ford GT demolished it and it would take 200k dollars to attempt to break that record.
What he can do is be the FIRST to put down a top speed number or standing mile.
