I've been told that the rule of thumb for straight piping you can expect about 115 cfm per square inch of surface area. So 3.5 is probably plenty. But then again we're all running 3 inch piping on N/A cars. So I always take it with a grain of salt.

I have a mix bag. Frozen boost/silicone intakes (same co) is pretty decent. Have alot of treadstone as well.

If i was going to do it over i'd prob do a FMIC but, maybe this will help.

On the inlet side i ditched that plastic thing as it kept leaking. So cobra head 3" 90 > hard straight >135 > 45 Hard pipe > 45 to MAF

How did you modify your Shocks, also which ones you have on?! Please it looks great
