Polarstar low air consumption setup. What am I missing?
« on: April 14, 2015, 09:17:59 PM »
So I have my p* sitting like this.

Red nozzle
.35 poppet shims in stock poppet
80-90 PSI
AK inner brass barrel

Still shooting 380 with .32

Is my inner barrel too long or should I get a gold low flow poppet?

Get a tight bore barrel and rhop.

A standard hop up nub has to pinch the bb really hard, and hold onto it for quite a while, causing wasted air to go right past the bb for a bit.

Same thing with your barrel, if the bb is loose, air goes right by it, wasting quite a bit. Pick up a Prometheus 6.03

What is your idea of low air consumption? What tank are you using and how many shots are you getting out of it?

Why would you be shooting 380 with .32's? That's way too hot for fair play if it's not a DMR...

LOL! I don't want to be shooting 380 with a .32

I chronoed that number before I replaced the 6.01 barrel with a stock brass 6.05+ m4 length and have to recheck chrono.

I am using a 4500/90 tank with an AKA SST reg.

My goal is to use 80-90 psi to be in the 400 fps field range limit with a .20. I was under the impression if I used a red nozzle and shimmed my poppet I could achieve that.

When I was at the op in New Mexico this weekend my gun barely ran right at the field limit of 330 with the .32. And that was a blue nozzle and zero pop at shimming

Add more shims, use a lower flow poppet, lower flow nozzle, etc. You just need to cut the air down, multiple ways to do that.

Also try out the new lightning Banjo valve, it's suppose To use less air, so you get 20-60% more to use for other shots. And holy crap... 380 with a .32?! Ivan teach me your secrets of crazy Fps on low settings.

I think it has a lot to do with the red nozzle a high DP setting and a 6.01 tightbore lol

That would make sense, I run a 300mm 6.03 with a red+ at 80psi and get around 398-400 with a DP of I think 12. Try turning the DP down... Lmao, but going to a 6.03 should help a bit, I'd reinstall your blue and bore it to the right diameter you need.

DO NOT use the dwell to decrease your FPS. You'll get poor consistency. Consistency and accuracy go hand in hand.

Set your dwell really high, dial in your FPS using other means, then slowly drop your DP until your FPS starts to drop, then re-increase the DP by 2 or 3.
