I've been fiddling with a small project for a while now, and it's finally finished (sort of). Having gained a little both in hp and in torque by "blueprinting" the intake and the rubber intake coupler, it got me thinking there might be more to be had in that department. I had two of these made:
This is an actual mini copy of the drawing I gave the guy who could run a lathe. It took him ten minutes...
Then I got myself a a pair of these:
Silicone automotive hose coupler id 44mm/1.75"
And a pair of extra intakes that got the treatment (blueprinting and removal of the vaccum nipple and the four tabs)...
This last pic shows the couplers mounted and inside them are the "bushings" from pic one made out of aluminium and totally filling up the space between the carbs and the intake.
Took a couple of good rides today, both single and two-up and the SOP dyno is happy with the result. If there actually is an improvement is something only a new dyno run can tell.
