Im thinking about designing/ building/ testing a carbon fiber intake manifold for the tC. Hopefully as my Mech Eng senior design project (if my professors allow it). Im looking for some info, and hoping that some of the experienced tC builders out there know any of it... If my work turns out to be beneficial to the 2azfe I can try to make more then just a prototype. Im looking for:

1. Mass (or volumetric) Flow. (A graph or table of flow vs RPM would be nice)
2. Stock Runner Inside diameter(or area of just 1).
3. Pressure in the plenum. (Graph vs RPM please)
4. Pressure in the cylinder during intake [Top Dead center, Bottom dead center] (Graph please)

As a default Im looking for N/A measurements. Thanks guys!

 

I would help if I could but I'm boosted, but here is what i know

1. If you can find the MAF values based on voltage, I can show you what a turbo car does. It takes about 8-9Psi to max out the MAF at 5V
2. Look at the guys who have made replacements, possibly email them.
3. Elaborate, I might be able to help a little bit here. Idle is about 21-24 inHG
4.good luck.

 

What can you read the MAF sensor with? And will it actually tell you mass flow? or would it just tell you fuel air ratio?

 

I read mine through the datalogging in my Emanage. Now for a stock person, with a little bit of electrical know how or help, could read the voltage straight fromn ECU or the sensor with a multimeter.

It tells u on a scale from 0-5v how much the air is. This value, combined with how much is flowing at each voltage point based on pipe diameter(stock is around 2" do not know exact) and Intake air temp (IAT sensor voltage)

I have several RPM based graphs that show voltage, but would need a chart or someone who knows a lot about the car to translate to CFM.

 

Ok thanks!

Just out of curiosity... Lets say this works and adds like 10-15hp to a CAI. Would anyone be interested in it?

 

^ It all depends on price and quality brother but I admire you being interested in the venture because few have gone there given the power the OEM is capable of supporting.
