well, i'll try to explain this in as few a words as possible
short ram intake - Better than stock intake
pro's:
fastest overal throttle response due to less distance the air has to travel compared to the stock intake and CAI
more horsepower in your higher RPM ranges
great for high reving engines
cons:
higher risk of heat soak which will rob your horse power due to the filter being deeper inside the engine bay
the horsepower gain is more noticeable in the upper rpm's usually ranging from 6k and up..
CAI - better than stock
pros:
Colder air enters the engine due to the filter being far foreward from heat sources which translates to your engine gaining a richer air content
increased throttle response over the stock intake system due to a much more constant pipe diameter, but not as good of response as short ram
power increase is fairly constant through the entire rpm range
Cons:
harder to install in some cases
throttle response is better but not as good as a short ram
run the risk of waterlogging your engine in the rain
And to answer your last question, there is no way that the CAI will crack your engine block with outside temperature air, Even people with interfreezer systems (A CO2 system that supercools incoming air from your intake to sub 0 temperatures) run low risk of cracking their blocks
There are systems available (IE: the ones available from WeaponR) that are convertable from Shortram to CAI Ram intake, which is essentially a shortram intake with a removeable extension pipe that attaches to the end of their intake cone.... These systems are nice for two reasons
1: You can have the bennefits of both systems
2: You can remove the extension for the ram air in the event of rain so you run 0 risk of water entering your engine...
I hope i've said everything in a manner that everyone can understand...
Please correct me if i'm wrong
