128jetsnake was this on the f6? i haven't had any problems with the mod on my f7 but honestly i never saw a real difference other than increased intake noise.

I don't think it would make a differance on minor mods like that. Might be a different story on a F8.

Yup, this is on a F6. The R's were about 100 less with the 440 intake on. That's not much but if it's less R's, then it's less power.

It's weird to me that other dynos show a loss of cfm on efi models, but a gain with carb models. But my superflow dyno shows an increase in cfm and slight increase in peak power on efi's and nice gains with carb models. But the big gain isn't peak power so much as low end throttle response and power. If you bolt it on, you can feel the response difference, something a dyno just can't recreate. Carb models will pick up 100 rpm at wide open by just bolting it on.
If you use a 440 intake the accordian doesn't compress all the way and can actually suck together causing a restriction. Ours in the same height as stock so this doesn't happen.

I mounted the BMP intake on my F7 '05 in february.

And I noticed a better trootlerespons for sure and also a deeper sound, so it worked on my sled :div20:

Hey you guys with his air horn......Can you reach in the intake of your sled? Even sitting in storage now, and in front of the air dam on the floor of the intake wipe it with a rag?

Is there a gob of oil sitting on the floor of the intake?

YES IT SOUNDS LIKE A FUNNY QUESTION BUT COULD YOU CHECK?

Anyone that don't have the intake can check too.
