I know this is a dumb question but I want to be smarter:  if the injection system is constant flow, why did you equalize the lengths of tubing from the spider to the cylinders?

Colyn,

 

There are no dumb questions. ----------- There can be dumb answers and this may be one.

 

Why, oh why have you asked why?  Who, oh who influenced me to do that? That is the question.  A fellow racer (who shall remain un-named for privacy reasons) was convinced his engine ran better with equal length injector lines.  He "suggested" that I might find the same result because of equalizing the effect of fluid drag in the longer lines.  I have not found any results that would indicate any difference and, at the next annual (assuming I am not too lazy), I may just switch back to the two shorter ones for cyls 1 & 3.  This will save at least .72 oz, thus allowing me to go faster.

 

Notice that you are not any smarter after that "excuse."
