Hood Insulation

[Southpaw]

This goes way back, but I did the foil delete, then I did the hood insulation delete to hear even more whistle. It was ok, but I wanted more. So, when I put on my ATS housing to fix my turbo surge, I went ahead and did a WW just for the sound. Holy 5h1t! It was so loud this way. The whistle was driving me nuts on the highway. It sounded great when it was spooling, but then it was too much. I was ready to take the WW out, when I remembered the hood insulation.
I put it back in and now I love it again. It is the perfect amount of whistle now. I didn't think that piece of cardboard made THAT much of a diff., but boy it does.

The reson i'm posting this is for the guys out there that just can't get enough whistle in the cab. If you have done the foil delete and a WW, then you should try removing this from the hood. It literally takes less than 5 minutes to do, and it's free, and it's easily reversible in 5 minutes.

You'll either love it and be glad you did it, or you'll have to put it back right away.

Let me know if anyone else has had the same experience with it...

I wish mine had more insulation, I can’t hardly have a conversation while driving mine.
It’s nice to roll that passenger window down and listen to it echo sometimes though.

I haven't done the foil delete, but might get on that soon. I was going to do the insulation delete but heard it doesn't increase whistle that much but now that you say it does, I'm going to give it a try

I really didn't notice that much of a difference when I first removed it. But when I had the WW in...That's when it really made a difference.

Before my Dad gave me the truck he said he had bought a new wheel for the turbo but I don't know if it's aftermarket or another stocker. And if it is aftermarket, I don't know what brand it would be or whatever.

So far, the straight pipe is playing the music loud and clear

All the aftermarket wheels are the same. They are all the early '99 style. Wicked Wheel is just one brand. But if he did buy an aftermarket one, it is athe same thing as the WW.

Oh, that's good to know. Thanks man!

All you got to do is look into the intake with a flash light at the wheel. If the fins are evenly spaced and look normal then it’s a stock style wheel. If the look kinda funny and are two close together then a space and two more then is the early 99 style wicked wheel.

Here is a pic of the “good” wheel on my 3rd turbo


and the regular wheel from my second turbo


and a dusted factory early 99 wheel from my first turbo

I'll have to post a pic of mine. It is a little different looking than yours. Works the same, and the same basic idea with the alternating size vanes and different spacing of them, but if I remember, looked a little different.

BTW, I think the term dusted is being nice for what that thing looks like!

Thanks for the pics! I really need to clean my intake so I figure I might as well check it out.
