+30-45 hp due to $30 part.

Subject: +30-45 hp due to $30 part. Tue Sep 11, 2007 4:16 pm

Well I made a discovery yesturday. I have been running with only 3.9 pounds of boost for nearly one year. First lets go back to the begining

- 3 months ago I installed a Boost gauge in the Riviera. It read Full vaccum but only 3 pounds of boost. I beliveved the boost gauge was faulty and needed to be replaced.

- 2 Months ago I visited a freind for headers and rockers install. I explained the odd gauge reading and he said the car pulled like it had no boost issues. ( he has a heavly modded 1998 bonneville ssei .

- Last weekend I was looking at this picture +30-45 hp due to $30 part. DSC08288

My car could not lay tracks like this and we are similary Modded. Mind you the BCA worked like it was supposed to but I had never checked the BCS. :? . Then I confirmed the Boost reading from the Gauge by Using my laptop scanning software that converted the MAP readinf (inHG) to PSI. And realized the Boost gauge was right. SO I bypassed the whole thing and well :shock: :shock: :shock: :shock: :shock: . The meter shot to 10 pounds of boost. And I left a Sixty foot streak down the street. twisted

What is the point of my post. For those L67 powered cars that do not have a boost gauge from factory. This should be your FIRST Mod.

I have replaced the BCS with the one from a Park avenue (Series 1 parts FTW!)

Sure, a boost gauge can tell you when your BCS is bad, but wasn't it the scanner that solved your problem?"

Boost Control Solenoid. I'm not sure what BCA stands for.
