After noticing incredible amounts of heat coming off an open header equipped race engine, I was wondering about getting cooler air to the carb. The cool looking scoops that the drag race guys use may be the ticket, question is, how do they attach to your carb? Must not use a center bolt like a regular air cleaner, do they use a clamp ring or something? I was snapping center bolts for a time and don't want to use them any more as this is a nagging problem. Should I just get bolts that don't nag so much? Tried higher grades of bolt, same crapola, best so far has been rubber washer under the nut and lots of torque to hold it tight. Problem with this rig is that the chrome air cleaner lid now has stress cracks coming from the center hole outwards. It will have to be replaced by ice out. Any ideas? _________________ It was like that when I got there! |

The easiest way is to use all-thread for carb studs that is long enough to come up through the scoop pan. I use nylock nuts than aluminum tubing for the spacers and more nylocks to hold the pan.
Just for safety I leave the studs a little long and safety wire them. I only use four even with dual carbs, the very front two and the back two. I usually don't run an air cleaner, but a piece of 3/8 alu. rod running the length of the scoop pan held in with the center stud holding in place a piece of 1/4" screen just to catch any thing that may get sucked in.
You need to make a couple holes in the very back of the pan to let out the excess air coming in the scoop and it will also let any water blow through that may be taken in. The exit holes depends on the size of the intake opening and the cfms being used.
If you're not using all the air coming in than the scoop will have drag and try to rip itself off. _________________ I refuse to join a group that would allow a person like me to be a member. |
