Finished Shoveling Snow Early so had some exercise and back to my Favorite Subject.

Now I am going to Post some images of different Carb Bonnets (vs Carb Enclosures). You can see the progression fromthe early pieces (1957) to the modern stuff (2018). So I will post the pics and then modify my post with words. This is the first batch of Bonnets. We will number them left to right 1,2,3,4,5.

And we will start with Bonnet #3. This is a very early Paxton Bonnet (more like a coffee can with a nipple on it)
No Idle Air Vent on this one Just a hole in the top for the air cleaner stud to pass thru and hold the Bonnet to the carb.

Then we look at Bonnet #1. This one they Lowered the Inlet Nipple and put it into the side of the Bonnet vs the Top of the Bonnet. They were trying out different airflow to the airhorn concepts. More on this one in a bit.

Then we look at Bonnet #2. This Bonnet has the 4 holes in the top to allow Idle Air into the carb/engine (as mentioned before)
so that the air does not have to pass thru the Supercharger.

Now we go to Bonnet #5. This Bonnet has a much larger diameter and the inlet nipple is off to the side. It is an old Bonnet.

And Finally we go to Bonnet #4 which is a modern Paxton Supercharger Bonnet, which has excellent air distribution to the 4 boosters of the blowthru carb. The owner of C&S Carbs "ROGER" (who makes fine "Blowthru Carbs") has tested this bonnet (with his carbs) and has stated it had the best air distribution of any Bonnet out there. No Bias to any one booster.
Notice how the design of Modern Bonnet #4 resembles Bonnet #5 (from the old Paxton Supercharger days of the 50s and 60s).
