I finally got around to installing my new 3.5" MAF sensor for my shortstar engine. This was the biggest PITA I've done on my car before. Summitt Racing claimed that the new sensor was a direct replacement for the stock sensor and that no modifications were required... WRONG! The stock ducting is all 3" while the sensor is 3.5." Furthermore, the new sensor is about a half inch longer than the stock one. I used all new ducting in order to make this sensor fit. (it was very tight BTW.) First onto the pictures:
This is the reason for changing sensors. Notice how restrictive the screen is on the stock one. The stock sensor is also made of solid metal and weighs a good 5 pounds or so. The Granatelli MAF weighs around one pound as it'* made from heat-resistant plastic. The new components will not allow heat to soak into the intake as easily as the stock setup did.
The stock setup also had this ugly bend that caused quite a bit of turbulence as the air went from the MAF sensor to the TB.
You can see how obstructive the bend is after you look through the pipe. It'* by no means a "straight shot."
and now to the aftermarket...
No screen... free flowing!
no nasty bends to make...
completed and installed:
I know, the blue part right by the airbox is out of place. The place I ordered from did not have anything in the color black at the time of my ordering. I will replace it later once black becomes available. Other than that it was worth it as far as I can tell now. As advertised, throttle response has been increased and all around the power is more smooth. It isn't like it was before where it was dead on the low end and the power would eventually come. It'* somewhat more of an even power distribution. The best part of it all is that the whistle that I heard under heavy throttle from the intake is now gone.
I attribute that to the bend in the intake, but I'm not sure if it was from that really, or not. I tried to take videos, but my camera is having a software malfunction, and my camera phone takes such low quality video that you can't even make the speedometer out. :(
It'* grainy to the max, but I think that was a 35-65 MPH full throttle run. I'll try and figure out why my camera that takes decent video is being such a PITA.
