Just got back from racing a friends buddy in his gtr. He didn't say all his mods bit he was running 15# at the time. We ran twice from 40-130. He pulled about 3 cars on me each time. I was very surprised with how I held up. If I ever get to build my trans and up the boost we are going to run again. He's going to run either 20# or if he can get some e85 he's gonna run 25#. But that's in the future.
