The 135 run was a top speed run which I was told is not very accurate, the last 2 runs that came in at 130.2 /.6 were the main runs. My buddy on a f2 ran 130.9 with a full system. On his chart it seems to fall off abit at the top end.
130.9s lowish with a full system, most full systems give between 9 and 12bhp [12=akra on fs ] that gives him a std reading of 119bhp
135 won't be that far off i shouldn't think , is that with ram air calculation or without [didn't see a fan ] you should pick up +5 to 6bhp with a can on a yank c model [by passes the cat ]
