Default Air Intake Questions

When trimming the shroud and fan blades, does that have any negative effects on cooling, mpg's, etc?

I'm getting ready to do a lot of work to my Yukon this weekend, and I was unsure of the impact of trimming the fan blades... Also, what did you use to trim them?

Thanks for the help. Before/After pics coming soon!

-Brad

Hey brad, no there is no difference in cooling. You are only going to trim the fan if you install a intake and TB spacer. On top of that you only tril about 3/8of an inch anyways. I used a tin snips, I hope you have strong hands.

Good luck

I'm putting them both on this weekend, so I really appreciate the tips.

Hand cramps, here we come!

I'll post pics when I'm finished...

Thanks!!

Why not cut the length of the intake tube instead of chopping the blades and the shroud? It seems to me that you could take the length out there easier.

Because the end of the intake is "barbed" to hold the cupler in place, plus the mounting for the heat sheild will not reach then. You really have to put one on to understand.

I understand that it has a larger diameter at the TB end in oder to upsize to the coupler. It also has ridges on it to increase clamping. I still think that you could have shaved the 3/8" off the end of it versus clipping the blades. I would worry about even slightly unbalancing the fan with the hack job I would do.

How is it that your getting a better mpg when more air is taken in which in turn burns more fuel ? I have always wondered that

it burns more of the fuel that usually is just pushed out the tailpipe w/o being burned. This gives more power per engine revolution, w/o adding more gas.

How bad would it be if the fan was unbalanced?

I would just take the time to tape a piece of poster board on a blade. Mark the contour on the poster board. Cut that out and trace it to each blade. Use a dowel sander or grinding burr to make them all the same. It would be more professional in a sense.

I know its not a turbine engine but if our blades are unbalanced it causes a world of hurt...lol
