Ken,

There may be several things happening here. 1st, as Oak mentioned, the pressure drop through that intercooler may be causing a power loss. 2nd, programming is critical and without seeing what the computer is doing, it is anyone’s guess. 3rd, see below re: your intake.

The OEM MAF housing that you are using is not designed to have a straight path of airflow pass by the MAF as you have it. If you look at the "clocking" of the MAF, it is rotated in the housing to compensate for the turn that air has to make when flowing through the OEM Airbox. You may find that straightening the MAF to the center of the housing may drastically improve your results. If you are interested I have a solution. We spent over a year testing and developing our new intake and have seen how minor deviations make drastic changes. Let me know and hope this helps.

 

Thanks AWE...Great seeing everyone Saturday...

 

Todd,
First off, thank you for your valuable insight. It is greatly and sincerely appreciated. I wanted to try the cone and velocity stack portions of your intake (as I indicated in my email) but timing prevailed and I wanted something for my "dyno date" this past weekend. I did receive your email about filling numerous orders and your promise to get back to me. Thank you.

In regard to the Gemballa IC....bottom line....it is what it is. I will live with the gain, the loss, the status quo, whatever it may be.

In regard to my homemade intake, YES, I absolutely took note of the slight rotation of the MAF in the chute. I assumed it was due to either exposing the hot wire to the airflow OR taking into account the near 90 degree turn the airflow must make to go from the filter box to the MAF chute. My original design, all drawn on CAD by the way, was for a CNC'd billet aluminum velocity stack/transition piece. That turned out to be too cost prohibitive for a one-off design. So, I went to the adapted setup in the pictures of this post. Idea to CAD drawing to machine shop in a matter of two days!!!

I was VERY curious to see the the angular rotation of the stock MAF in the stock chute. You did use the word "drastic" improvement, so I will heed your advice and make some modifications and re-dyno the car.

Todd, can you please tell me what the horsepower and torque figures should be for the Stage 4R programming??? I cannot find them published anywhere.
Thanks,
Ken

 

Ken,

The rotation of the MAF is solely due to the turn that air has to take prior to the MAF. By having that meter off centered will cause an incorrect read of the air entering past the MAF thus causing a possible lean condition. Call me later on today to discuss. Take care

 

Hi guys!

Thanks to everyone who participated in this event. It was an easy and relaxing day.

I say we shoot for a barbque/carshow sometime this summer. Who's game?


I threw together a quick gallery of the day here:

BBQ/Car show/dyno...I am there
Great bunch of guys at AWE...anyone up there want to help me do my clutch tomorrow?? ...lunch is on me

 

Good numbers guys, so far you have some
more work to do to catch up with the RED BEAST! But I am sure you will!

Sounds like a fun time for all!

 

Of course I have a few things cooking for the old girl as well. Might have to get some updated Dyno numbers.
