P Mass Cold Air Kit

[michigan stang]

Well I was lucky enough to have the P Mass, Mass Air Company contact me to us my car to develop a cold air kit, mass air meter, and throttle body. After talking to them I have agreed to let them do so. At this point I have dropped off my stock air box and air tube to them to flow test. Next will be to wait for their kit to be mocked up and take to the dyno and get before and after numbers. They say that the kit will not need a tune as the mass air meter they are designing will take care of that. I will let all of you know how this works out and what kind of power upgrade this produces. I will also post pictures as I get them.

Congrats, hope you get some good numbers out of this and a free product =D

Kinda reminds me of the days of the C&L mass air meter on the EEC-IV ('89-'93 5.0) cars. They had the different sampling tubes you installed depending which injectors you were running. Tricked the ECU and worked great. Set up was so flexible that I used it on my car from the first modifications (throttle body, mass air, conical filter) up to a blow thru set up on a Procharged 351W.
I'm old school with modifying these cars and that is why I'm still just a bit confused that we have to constantly redo tunes anytime air flow into the engine is changed. Just thought that was the point of a mass air meter, to measure the amount of air entering the engine. It seems now it's almost like a speed density setup and all changes now have to be accounted for in the programming.
Sorry, didn't mean to hijack the thread and totally change the subject! I'm definitely intrigued to the setup.

I suspect the MAF sensor is placed near the middle of the intake in order to read the highest velocity of air flow. If you change the shape of the intake leading up to the sensor, you can also change the velocity profile, so that the calibration of the sensor (the original tune) is no longer applicable. Re-tuning will fix that. Not sure how important a tune is, but I can see some reasons why one would be useful in theory.

Looking forward to seeing what these guys come up with.

The Sample mass air meter they showed me took the air reading thru a series of holes around the inside diameter of the meter and passed the air thru a channel them thru the actual sensor and them back into the air stream. They explanded that with most of the meters out there, the sensor does not reach the center of the tube as the tube diameters have increased so much and get a false reading and poor idle. I guess I will see when the product is reading for testing. The company looked to be very well set up and conected in the performance field so I am kinda excited to see how this plays out.

Update on the P Mass Cold Air kit. Just left the offices of P Mass and was impressed. They have flow tested the stock air box and intake tube assembly. Looks to max out at around 500 hp and the inlet that mates to the core support starts to suck in and choke itself off. They already had half the parts made up for their kit and got to watch the elbow being made on the 3D printer. They also had the jlt kit there so we can do a side by side test on the dyno to see what the power increase is on both kits and the stock set up.

typically meters are pricey, especially good ones. the stock meter we have made 1000rwhp.

should be interesting

That inlet has the cross section of a 123mm "CAI" that guys have been making 800+hp with for years now.
