Turn Mazdaspeed3 CAI to Short ram

[SILVERSPEEDY3]

did some research

on the way home from work today i studied my intake air temp (dashhawk) and i saw an average of 4-5 degrees above ambient air temp. (with mazdaspeed cai). it was around 50 degrees and my intake air temp was 55. after dinner i converted my cai to a short ram. studied the intake air temp and found when driving it was still 5 degrees above ambient air. yes the iat heats up quicker when at a stand still but as soon as you start moving the temp goes down to the same temp as a cai. just my 2 cents.

That's all the more proof CAIs are worthless. My prediction: in the future cais will be looked back on as one of the biggest mistakes in history.

i think the reason your scuba tank feels cool to the touch is because the tank itself is acting like a heatsink and releasing the heat to the atmosphere. basically, if you keep volume constant, the Ideal Gas Law tells you P1/T1 = P2/T2, so if you increase P1 to P2, then the T2 must increase too.

That and how quickly you pressurize/depressurize will affect how much heat or cold you feel... if you pressurize that tank to 3500psi at the same rate as the turbo does it in your car you will feel the heat as radiated heat wont have a chance to escape...

oh and by the way, the 30 hp gains with the mazdaspeed intake are a highly debated subject, as most of the gain in power is from changing the air to fuel ratio by using a larger mass air flow housing which "tricks" the computer into thinking that there is less air coming into the cylinders than there actually is. Think of it as sort of tuning your car without using a computer. You can search the forums for threads about this. there are tons of them WITH dyno sheets. I mean, you can't really argue with the dyno.

Just skeptical thats all... it really means the stock intake had a LOT of room to play with... on the C6 stock intake is very unrestrictive so Im not used to seeing 30 HP gains (even if it was intake/exhaust - C6 dyno come in around 3-4% improvement) - 30 HP is almost a 10% improvement that should have been a no brainer on a MS3... me thinks the sound bean counters got carried away....

Im gonna go on a limb here: If they are tricking the computer into thinking there is less air coming in it means they are leaning the mixture out as it would push less fuel (more air and less fuel = lean)... I could have sworn a leaner mixture equals less power but Im no expert... seems if they are tricking the computer it would be to make it think there is MORE air coming in and making mixture richer for more power (albeit I cant see our cars running any richer without flooding the engine )

leaner = more power ....to an extent before it goes boom. If the MAF thinks less air is coming in than really is...it's not going to add as much fuel so it will be leaner and more power. These CAIs and stuff mainly just allow more air, which results in more fuel and thus also power.... BTW the mazdaspeed CAI uses the same size MAF housing.

Yea leaner is more power but more dangerous as well.

anyone have problems with the MS CAI as a SRI
