yo javier seeing as you work for this company, can i ask a question
which valve duration do you use in calculating your lengths for the exhaust
for pulse tuning
is it
a) exhaust valve open duration
b) exhaust valve open duration - valve overlap duration
this is not a trick question ok
im just curious as i design these babies myself, and ever text ive seen says A, but you could design for both i think if you aim at having in B the pulse arrive at the exhaust port just as the intake valve opens, and then again as the exhaust valve is about to close (A)
what you think?
