[QUOTE="Nazman, post: 7586378, member: 986"] Ok Folks, There has been lots of debate lately on the question of: are the extra CIs worth in a boosted application? For example: 284CI vs ~302CI Stroker, 304CI Big Bore or 322CI Big Bore Stroker Some say that it does not matter, just up the boost, others (me included) will say the more CIs the better. Well, I build these two Turbo Consumption Chart for Modular 284 and 322CI BB/Stroker just to see if the extra CIs were worth the dollars and here is the data and my findings. Take it for what is worth. Again, just wanted to see it in paper and the final decision its yours! So, here its. The first chart is a 284CI (.020 over) Modular, and that followed by the 322CI Big Bore Stroker....Sorry, no Stroker chart as of right now, but will do one soon and add to the madness. I utilized the following factors: 85% Motor Efficiency 130F AIT Intercooled They are all the same for the two charts. HP is rated “at the wheels”. Boost level from 10-25PSI and 3000-7800RPMs. [B]284CI Modular @ 85% Efficiency, 130AIT, Intercooled, Power "at the wheels":[/B] [IMG]http://forums.mightymustangs.net/gallery//1227948302/gallery_1217_503_65187.jpg[/IMG] [IMG]http://forums.mightymustangs.net/gallery//1227948302/gallery_1217_503_361025.jpg[/IMG] [B]322CI Modular @ 85% Efficiency, 130AIT, Intercooled, Power "at the wheels":[/B] [IMG]http://forums.mightymustangs.net/gallery//1227948302/gallery_1217_503_304145.jpg[/IMG] [IMG]http://forums.mightymustangs.net/gallery//1227948302/gallery_1217_503_71202.jpg[/IMG] Some of the “analysis” at the most “common” PSI and “a realistic” RPM point: -284CI @ 6500RPMs AVE HP X PSI = 39.63 HP @ 10PSI = 513.7 HP @12PSI = 555.3 HP @ 15PSI = 611.7 HP @ 18PSI = 680.0 HP @ 20PSI = 721.6 HP @ 25PSI = 825.6 -322CI @ 6500RPMs AVE HP X PSI = 44.93 HP @ 10PSI = 558.8 HP @12PSI = 629.6 HP @ 15PSI = 700.3 HP @ 18PSI = 771.0 HP @ 20PSI = 818.2 HP @ 25PSI = 937.1 Now, it’s time for discussion!
