CAI or Short Ram

I liked the extra room too, but the thing is any extra temp increase carries over into each process. Example:

If the intake air is 10 degrees hotter,

1) the turbo's outlet temp will be 10 degrees
2) the Intercooler discharge will be 10 degrees hotter
(are you seeing a trend)
3) the combustion chamber will be 10 degrees hotter
4)Finally, the EGT will be 10 degrees hotter

You see ingesting ambient temp air is well worth the effort, especially on a turbo car. imo the effort was already put forth by the engineers, so save your money and use the stock CAI and just add a K&N.

Thats exactly what i was thinking. I hate when people post false information that makes absolutely no sense.

Not true. The intercooler will cool that 10 degrees down based on the efficiency of it. The point you make, however, is accurate and I am merely nit-picking. Just pointing out that the discharge my likely be 5-7 degrees warmer than not going with one though.

Yes you are correct

I applied the characteristics of the compressor's adiabatic efficiency to the IC's thermal efficiency.(hate it when I do that)

With a 10 degree temp increase to the IC inlet and assuming 75% thermal eff the outlet temp increases by only about 2.5 degrees.

You are correct. With my Superbeast and Injen SRI my temps at intake sensor was only a couple degrees above ambient air temps at speed. This was check with an Aeroforce gauge which reads computer read temps at sensors. An efficient intercooler at speed will cool ingested air before it reaches intake. That is their purpose and design.

I love that book!!!! Because of this book I started w/ moding my suspention. so my car would hold the power it came w/ b4 adding more power/torque.

put a K&N dropin in the air box and take the top off of the box. You will see a larger gain per dollar on a mildly modded srt4. invest the money in an AGP or Forward Motion WGA

Have any of you tried just removing the stock black intake box and just putting on the k&N filter on the end. Looks just like a short ram... Are the after market intakes any bigger in size then the stocker?

I think most if not all the intakes sold are 3"

[svt101]

Whats stock 2.5?

Well I just bought a Injen short ram. To me they look and sound better. I loved the look of the Mopar CIA except for the fact that it was $298 and I was nervous about having my filter down that low.

It seems to me its like any other mod you can do to this car. Its all a matter of opinions. Guy A says its a waste when Guy B claims its an awesome mod. Then Guy C will swear up and down he saw a slight power gain. So really, it all boils down to what you individually want to do with your car. Thats just my 2 cents.

unless you want a good chance at hydrolock, go with the SRI
