Re: stock air bock lid to whisper?

yes, but it's still not a whisper lid.

Re: stock air bock lid to whisper?

you'll still be left with the oval port at the back, which creates alot of restriction. There's no replacement to a whisper lid; they're taller and flow much more smoothly than anything you could do to a stock air lid

ok thanks guys

Re: stock air bock lid to whisper?

why would oval be worse? seems like you would actually get more flow with an oval, especially since the oval has a much higher surface area, about 2.25 sq. inches more than than a circle, based on my rough estimating. Not that its going to make much difference....but remember that the V8 throttlebody is an oval.

basically the TALLER part is the only difference (and the important one). If it makes you feel better you could probably trim out the support bar in the port.

search the free ram air mod... there is a sticky somewhere with pics...

IMO its better then stock but the whisper lid is more what you need. If you look around you can find one pretty cheap. I got mine for like 70 dollars. You can see the difference between the stock lid sanded down compared.

Is the throttle body inlet also oval?

not on a v6. I think the outlet is...I haven't taken mine off though. The inlet is a circle (engine tech says its 65mm- not sure if that means the inlet size or what, I don't have metric measuring tape handy) that is almost exactly 3 inch.

TB is round, stock box is oval. Don't know about restriction but the straighter the shot with less transitiion or resistance the better.

by the time you go through that much pipe, intake manifold ect, I'm not sure it matters that much. volume seems much more significant. If your worried about smooth flow, then those rubber collars ought to worry you a lot more.

1)You're measuring the wrong dimensions.
2)What matters in an intake is volume, not surface area.
3)Even if they mattered, your math is way off


^this is as simple as I can explain it.

but remember that the V8 throttlebody is an oval.

^Do either of those look like an oval to you? That may be the case on the LT1, but the LT1 is an inferior motor

Re: stock air bock lid to whisper?

can't see pictures from where I am, I'll take a look when I get home.

Re: stock air bock lid to whisper?

Just trust us... If the whisper lid didn't work better then stock then majority of the people on this board wouldn't have it or reccommend it. I'm not saying everyone on here is right (even though some may argue that) but experience speaks for itself.

the path the air takes before it reaches the inside of the intake manifold does have a significant impact

volume seems much more significant.

...and the best way to maximize that is with a round port at the back of the lid

If your worried about smooth flow, then those rubber collars ought to worry you a lot more.

another reason to buy a whisper lid...Which, brings me to my next point: It seems to me that you've never seen a whisper lid in person, and are just extrapolating with no real support. If you had ever seens a whisper lid, you'd know it doesn't have the first rubber collar on it. Before you continue posting, actually get your hands on a whisper lid and install it

Re: stock air bock lid to whisper?

On my 2000 it's lid, 3" tube TB. I'm pulling more air through with the hole I cut in the air lid base so it's pulling more air from in front of the radiator. Maybe on other cars it's going through tubes but on most it's a straight shot into the engine. The less restrictive and more uniform that path is the better.
