Yeah, it could be. I didn't measure it, I eyeballed it with the rubber bellows still on it, so it could be. Even so, the coupling issue still exists.

Do you know the details of Hector'* tests?

My frustration here is that I am not able to get solid information. Don't get me wrong, I'm not frustrated with anyone in the group, I'm just trying to get very specific information.

I have no doubt that you have (and others have) achieved results. So far the reports have been for pre 2000 Bonnies, and SC Bonnies. In another thread, someone is talking about the ineffectiveness of gutting an airbox in a Buick. So far, no NA 2000+...

...am I repeating myself?

Bill actually know more about the Hector tests then anyone else currently on here I think. He was always brought it up in the past.
I mainly look to other cars making similar whp (since flow = hp) and see what size intake they make the most power on.

I have a homemade CAI, used the Autozone pipe, K&N cone filter, and made my own heat sheild. I was completely satisfied with the result. It definitely improved throttle reponse and a nice sound when accelerating. Whether or not it is an ideal set-up, maybe not, but as Bill said it was definitely an improvement. The outside diameter of the pipe is 3" and the OD of the TB is 4". I can take a picture if you'd like to see. it. If you went with an Intense FWI, I don't think you could go wrong there either.

Thanks JAmon!

A picture would be GREAT!

As they say, a picture is worth a thousand words!

In regard to it being ideal or not, I subscribe to the 80-20 rule...

80% of the result - 20% of the effort.

This is the FWI and PCM tray, since you PCM is currently in the bottom of your airbox.



and this is pretty much what it looks like in your engine bay, mine is an L67 but it'* similar on your L36.

Thanks JAmon!!!

I like it! Your flexible coupling to the TB is a more gentle angle than others I've seen. There is a good chance you don't get the flow separation I was worried about.

Nice arrangement! Nice cold air box!

(I ignored the dirt)


Oh, by the way, where is your IAT?

The pipe already has a hole in it. The arrow points to the IAT sensor wire. The sensor is right in front of it.

Hawkjet, your TB isn't 3.5 or 4".

Your throttle plate (which comes at the end of a smooth transition) is only 65.45mm, or 2.5".

These are my own measurements with every TB listed in my posession.

I have a friend with a '97 Supercharged Bonneville. Last night he e-mailed me with the message that the throttle plate was 2.5" diameter.

Then you post this. Great information!

I quickly glanced at the thread you linked to. I will spend more time with it later. I too have a machine shop so I am interested in finding if there are noticeable gains to be had by spending a few hours on the Bridgeport.

I have a Series II Bridgeport CNC, Series I CNC, manual mill, 13x39" toolroom lathe, surface grinder and miscellaneous drill presses, sanders etc. I am a toolmaker, moldmaker and mechanical engineer.

If you have suggestions for simple and effective mods, I'm all ears! (It will probably need to be a new thread though)
