is that safe?

does anyone else done this??

yes lots of people have done it, including myself. yes it is safe. some say you will lose power...but to be honest...i dont. and i doubt youll feel the power loss if there is any at all. it's hella louder now though and it was a free mod

I ran this setup up until I got my spacer. After installing the spacer and with the duct still removed, the VQ felt too soft down low for my tastes. Above 3500rpms it felt great and sounded damn sexy. I went to the track back in November and ran some upper 14.3s/14.4s at nearly 100mph with just the spacer and no duct, but my slips were indicating that my car was fractionally slower in the 330' confirming that the lowend power was impacted. I put the duct back on and the lowend feels a quite a bit better, though the sound and snappiness of the throttle isn't as fun above 4500rpms. Overall, the driveability seems to have improved. My theroy is with the open airbox and a spacer, there is too much flow through the airbox/MAF/intake manifold which causes a erratic MAF readings and air turbulence through the intake tract during lower rpm, especially at full throttle. I've seen this same issue with my old Maxima and LT1 Z28.

but i'm willing to bet he doesnt track his car (nor do i) so it wont make that much of a difference for our daily driving purposes

More misleading information from those who know not!

me? i'm just reporting my thoughts. i admit that i have no tests to prove what i'm saying. but honestly, for daily driving i dont think removing the power duct is going to affect you a whole lot

Post your datalogs and legit 1/4 mile times and maybe you could gain an ounce of credibility on this site. Merry Christmas

Jeebus guys, not this **** again.
