would it be logical to go to about 8.7:1 or 9.0:1

i can build the heck out of a ford but when it comes to building a supercharged gm v6 i am lost.

Look at this list:

Not a single car on that list is anything other than 8.5:1 compression that I'm aware of.

You're not getting on anyone'* nerves. We're just trying to get you to keep all your information in one topic so we can keep up with you easier. It'* alot more difficult when you're asking Performance questions in 3 or 4 different topics.

Keep it all in a neat little package, and we'll be in a much better position to get your 'big picture' and help you.

is the stock, dash gauge reading low? if so i believe it gets the signal from a map sensor. and the new one is close to where mine is at. just below 20 in/hg.

Rivieras have no factory boost gauge.

That'* a huge deviation between gauges there. What brand are they?

You *need* to check your fuel pressure when the engine is under a load. Doing it in park will not get you the results you need, no matter how high your revs are.

You also need to get that KR under control. Do the FWI. Get that engine cooler somehow (yes do the 180* and fan bypass mod). Make sure your cat isn't clogged, and your fuel injectors are cleaned. And go over the engine with a fine-tooth comb for anything loose. Oh yeah...and make sure your O2 sensor wires are routed away from the spark plug wires.

One more thing (in ancient Chinese Man'* voice)...make sure the MAF sensor is clean.
