will this really raise bhp or not ???

[guest]

i just aquired a 850 t5 auto ok..so as you can guess im new to all this .in work today i heard 2 guys talking over lunch and one of them said that he has had the vacum pipe that comed from the actuator blocked off and his car is over 300 bhp

is this true or a load of the old b/s

It'll give you plenty of fun until one of two things happens:
-The ECU decides to stop your fun.
-You break something.

300bhp is very unlikely by doing nothing but blocking the wastegate.
It's also not anywhere near the safest way to increase power. It will work (in a fashion), but it will put undue wear on the turbo, and you run the risk of detonation and preignition, which equals engine death.

My cousin had a 2003 WRX that got stolen. The theives put a vicegrip on the actuator for the waste gate. This caused the car to have constant full boost. When the car was recovered it was sent to the factory for repairs where they had to replace the turbo and both the catilitic converters in the up pipe and the down pipe because they were destroyed. The thieves only had the car for 3 weeks.
