Here is a low cost $69 pen type oscilloscope that perhaps could be used
for investigating the intake pipe pressure pulses and their timing.
No need to make your own.

Resolution?
How is it triggered?
Time base specs?
What powers it?
What is the input voltage range?


I am looking into it further as there is little info
on their web site.
