Should it be fine in 1 bar? 429ci

[02Ls1]

Guys should i stay in 1 bar to tune my 429 ci? I will be running it all motor but definitely going to spray at least over 250 shot, but first i will be running it all motor.

I know 1 bar its to 105 kpa, 2 bar 210 kpa and 3 bar 315 kpa. I know there's no way i will get 210 kpa naturally aspirate but i was wondering if this motor will pass 105 kpa?
Or i will not have a problem with the 1 bar if i stay under 8,000 rpm's? Which i will not be shifting that high.

Unless you are running boost, you shouldn't see anywhere over atmospheric pressure. The pressure changes depending on the altitude. Atmospheric pressure at sea level is 101.325 kPa. Now please keep in mind, if you go below sea level, you will see higher values but not by much. You will be ok with a 1 bar system, unless you go boost. Hope this helps.
