What are the determining factors when choosing to spray a tight lobe sep cam. Ive found that whomever you ask about says 110-112lobe sep thats it.. But I know theres someone that can shed some light on this... BTW its a lunati 40139 flat tappet solid with a 106lobe sep.

When you use nitrous and blowers you want a lobe sepration at 112-114 to give the cylinders as much time too fill up to make the most power.

so if this is the cam i'm going with the best thing would be to spray it until it doesnt change much? max would be 300. norm 150-200 plate kit.

the tighter LSA will allow the nitrous to flow out during overlap....

good cam choice for making power in a N/A app.. As for spraying it,, you'll have to make a choice in the converter selection...Will it be loose for running just motor or running with spray more times than not...
I would choose a converter thats gonna be alittle on the tighter side as so when the NOS is sprayed it'll loosen up to make the motor happpy.
