flowing nos fuel pressure??

[ts racer]

what do you guys do when flowing your nitrous fuel pressure?

do you keep the same holley jet (73)?
or do you change the jet as you go to a bigger kit?

i hear both ways,but what is the most popular way.

thanks,great site

Use the same jet for consistancy. All jets flow a little different so it is best to stick with the same one. Unless you are using a plate with only one jet. You can use the jet you are going to use when adjusting fuel pressure.

I used a 73 Holley jet for everything. I used to flow the nitorus side while the engine was running at idle. The pump would dead head a little when I tried to flow the fuel pressure without the engine running.
