I was thinking like 8.5:1 for static before my cam and turbo is taken into account..
and 12.5:1 dynamic afterwards
As for off boost performance; do you think 8.5 will be puttin around, or adequate?
what's the lowest you've gone on a street motor?
using a dynamic compression calculator...only taking into account cam opening/closing, rod length, and dimensions physically machined to 9:1.... im getting 5.84:1 and an effective stroke of 2.3 inches (30% less than actual dimensions)
Im running KG-10
--did I pick a cam that's letting too much charge blow out my engines' a** until higher RPM?
-- will 8.5:1 be comfortable? Will the non-destructive koolaid man make a visit every time I hit the gas... "heyyyyy *BOOOOOSTIIINN*" skkkrrrrrrrrrr----rrrrt *CRUNCH*
thanks and happy 4th. Dont blow your dick off.
edit: I've spent the morning reading, and these are the two most useful pages i've found. https://www.researchgate.net/post/H...ion_engines_achieve_higher_thermal_efficiency
http://www.eng-tips.com/viewthread.cfm?qid=90282
and http://physics.stackexchange.com/qu...ombustion-engines-more-efficient-on-cold-days
so I think actually a compression closer to 9.0 or 9.5 would be for the best. if 50% of my power came on from 2700 to 3200 it doesnt take a genius to think about what the wheels are going to want to do, and very quickly....
also, the higher compression ratio will benefit power production from efficiency alone.--- as anecdotal evidence always leads to... "low end is better with higher CR"...."shes a torque beast with that high CR"... I guess I finally understand where it comes from from a thermodynamic point of view...
