Now I know most people won't be able to answer this but enough people have been tuned and been dyno'd to be able to add a logical amount of input to this.
On a kb/whipple set up is more boost at lower timing or higher timing at lower boost going to yeild more tq/ hp?
I ask because I am currently at 11 degrees timing (with plently of room to step up to about 15 degrees) at 14 psi. I'm wondering if I should pop on the 3.25 upper I have and rock out the 16 psi or up the timing and see where I stand against others running more boost. I have a friend in Tucson running 16psi and 15 or so degrees timing but he's got long tubes and I don't know how much those are helping him with the 16psi.
I know there is a calculation for bar pressure over na hp = estimated hp increse of 1.75 times or something like that, my turbo skills have fllen off... I can't tell u how to calc speaker box enclosure cubic footage anymore and I used to own my own shop, get that!
Anyone with some good insight?
