Here is a source Mark for the required silicone hose couplers. They come in either blue or black and two different lengths 3" or 4".I am finally able to get started with the build. After taking inventory and putting the parts in storage, I wanted to build something, so I assembled with Tilton Pedals. As many have already said, they are nice! It is hard to know how to adjust them until they are in place, but at least I know how they can be adjusted.
Most of this build will be pretty standard, but I do have a few things that may be unusual. I want to get those started, so I don't use up space with standard things that may be needed by the few special items.
The air intake is one of the special items. I want cold air intakes using the side body scoops. I understand the Robertson race car has this feature.
The first order of business to achieve with was to decide on air cleaners. With help from contributors earlier in this build thread, I decided on K and N's cold air intake. I am aware that at high rpm levels, the air flow may be less than ideal, but is will be close.
The first problem is that the 4 inch throttle body diameter down to the 2.75 inch air cleaner diameter requires an adapter that no one makes, not K&N, or anyone that I could find (see photo). Fortunately, the local Ace Hardware plumbing dept. had 4 inch to 3.25 inch adapter. I then found a an automotive piece that had an outside diameter of 3.25 and would go down to 2.75. First (of many in the future) problem solved.
