So, Im trying to get a grip on this venting a Viper airbox to the atmosphere, as my Viper currently is.
I know it takes a much leaner jet than if its vented to the airbox.
The sled has SLP pipes and has 156.3 mains, 45 pilots, clip pos 3.
I have never ridden this sled at all. Thats how it was when I got it.
SLP says a 162.5 main jet in their instructions, but have read that may be a bit rich, so Im thinking of a 160 main.
Wondering what the equivalent is if not vented to the airbox.
I have seen people say its 10 points leaner, so like a 150 main.
Also, does the vent affect just the main jet, or is it all the carb circuits?

vipers usually ran ritch when the vent was forgotten to be installed on the air box.
Yep, just wondering if someone has a more precise formula for this.
Example: if you use a 162.5 main when vented to airbox, use a 150 main when vented to atmosphere

I would think mostly main jet as there isn't much vacuum created in the airbox until full throttle.
