For those with CAI's
 

That's "Cold Air Intakes"

I was messing around with my GReddy Infometer and was looking at my intake temps this past weekend. On Saturday the temp outside was about 55 degrees and I was getting intake temps in the 90-100 degree range. http://erieridez.com/phpBB2/images/smiles/icon_eek.gif Mind you my car had been idleing for about 10 mins in the driveway as I was cleaning out the garage.

On Sunday same outside temp of about 55 degrees but I was now getting intake temps in the 70-80degree range at idle and 65 while in motion.

I can only imagine what kind of temps I would get when it is 90+ degrees outside!!! http://erieridez.com/phpBB2/images/smiles/icon_eek.gif http://erieridez.com/phpBB2/images/smiles/icon_eek.gif

So I think I have found a way to get those intake temps under control.

It says that it will block over 98% of the radiant heat from the motor bay.

Less heat=cooler intake air=More power!

Don't forget that a motor expells 33% of it's energy as heat 33% goes to the wheels and 33% pushing out the exhaust.

With a free flow exhaust and controled temps more of the energy can go to the wheels in an more efficient mannor. That combined with my
MD Spacer/Thermo gasket should keep the temps in check!

See you on the streets!!!

42 dollars shipped... not bad....
do you have the thermal wrap?
does it fit?

did you order one yourself? id like to see some testing with it and it sounds like you have the setup to do it.

nice find, its like heat wrap for the intake

Not yet...But I think I am going to order.

I was just a bit surprised by my intake temps.

I have the Thermo-tec Cool Tube intake heat shield, the one you have pictured, wrapped around my intake tube. It's more for looks than functionality because I figured that the amount of time the air spends going up the tube is less than ½ second so it isn't going to heat up much. Every little bit helps, but it will be minimal.

You'll see better results from the Motordyne Isothermal gasket and the TB heater bypass. I did some temperature measurements of my upper plenum before and after and it runs about 30ºF cooler. Considering that the air flows through the plenum slower than the intake tube, it has a better chance of heating there. Do you have the Throttle Body heater bypass installed?

I have an OBDII monitor that I run in my car and did some temperature measurements similar to yours. At highway speeds, the air temperature at the MAF sensor is only about 5ºF higher than the ambient temperature. Not bad for the stock intake. That's probably why a CAI doesn't really show big gains on the Z.

Thanks for the info.

But the surface temps that the CAI gets is waaaaay hot! So who knows?

True - the metal tube used on most of the CAI's is a great conductor of heat so they do tend to get hot or at least they feel hot. That's why I like my good old plastic tube wrapped with insulation.

i'd hit it!
how about a group buy to get the price dropped to like 30 dollars?

^Unlikely since it is from Jegs...

That why I like the design of the Typhoon intake. It has the front mounted air scoop that brings in fresh air into the air box. I can see why the plastic Z-tube is a good thought.

The one thing I might also do is wrap the outside of the air-bow with a few sheets of that thermo wrap since themetal box is conducting heat also. Since the Mass airflow is reading temps right after the intake filter it would be picking up the temps inside the air box.

I've been tempted to buy one of their thermal blankets and make a cover that would surround the box and MAF part of the intake tube. That would probably help keep it a little cooler, but would look like crap I'm afraid.
