fair enough. I'm always interested to hear others opinions. so for a Supercharged (6psi powerdyne)Tickford SOHC 4L I6 you reckon GRA would be the way to go (or one of the better ways) if power was the prime concern with economy secondary?

my dad has a powerdyne supercharged xr6 wagon that is running the GRA setup its good for 252rwhp on 8psi, i can post up some picks if anyone is interested

sure the GRA will do the job, easy to set up & & gives you good mixture control......make sure you get someone that has GRA knowlage as there more involved than what the average gas mechanic relizes.
