**Impulsive_154** · June 26th, 02:58 PM

I just got my Impulse on Wednesday. So I went out to shoot it with my 48/3000 HPA tank. I set my Operating Pressure to about 170. The Dwell was turned up 1/4 of a milisecond from the normal setting. I started shooting it and it was fine. But after a while, it started to chop like crazy. There was paint all over the inside of the barrel. But the bolt was also covered with paint. I figured
that the dwell was just set too low, but I didn't notice many balls chopping in the gun, most were breaking in the barrel or in midair. Also, I only got about 300 shots out of my 48/3k Tank! Are my settings messed up, or is my gear? Any help will be appreciated.

Your input pressure seems a bit low to me. On a stock impulse you should probably run your input up near 200 psi. Once you adjust the input to 200... then adjust the dwell to get the velocity you would like.

You can't go low pressure on the stock impulse very well. You really need to upgrade inorder to do that efficiently.

Also, the imp is notorious for being a gas HOG. On my stock imp I would pull around 600 shots on a 68 ci 3000.

Your best bet to improve efficiency is turn up the input pressure.

As for breakage in the barrel, that is most likely bad paint or a bad paint/barrel match. If your getting breakage on the bolt and in the chamber, that is probably chopping caused by outshooting the feedrate of your hopper. If you have vision USE IT... otherwise you will need to limit your firing rate (if that is what is causing the chops.) Otherwise (however unlikely) make sure your ball detents are compressing properly.

**Impulsive_154** · June 26th, 03:57 PM

OK thanks for the help with the pressure, I will do that.
As for the breakage, I am using an eVLution 2 loader, and I didn't think I could outshoot that. That could be the problem though.

Also, I know there are other posts on this, but what are some good parts that will make my Impy more efficient? Are the EVIL parts any good? (respirator, bolt, valve, etc.)

**SpYdErGuY7080** · June 26th, 04:18 PM

I know your past this but i have heard the best dwell setting is at 10+ (and to set it to 0 you hold the one nearst to the back till you hear it double cherp) then press the second one at the front 10 times. And then set the regulator to about 175 or so and chono, if that is too low set it to about 200, if it is still low, open your dwell up one or two again and set the pressure down to 175 again, repeat if nessesary. w00t hope that helped. And the evil parts are ok they are more show than go, i would recoment new designes parts, they kick.GL

and have any other questions just ask

**paintbug** · June 26th, 09:50 PM

dont use the pressure to adjust your FPS. for a stock impy set it to 190-200psi then use the dwell to set your velocity. it offers the best efficentcy that way. then you can upgrade some and get it lower. stick with the New Designz parts however they are the best plain and simple. i have tried others and none compare.

**Impulsive_154** · June 26th, 09:52 PM

Thanks a lot. I was looking into the ND parts, because I heard they were good. Also, I have one of their triggers and it is amazing. But my friend is totally obsessed with evil (to the point of coming into school wearing his paintball jersey, including gloves and headwrap thing) so he said I should go with the EVIL parts. But I will probably end up gettingt he ND stuff.

And the problem with chopping was probably caused by the Dwell being too low, because I didn't have a chronograph so I had only turned the Dwell up one click.

**SpYdErGuY7080** · June 27th, 12:29 AM

he did all that? hahaha thats horrible, but yes ND would be the better route and in the end you would be much happier with.

The manual says not to go over 200 input pressure. I run my Impulse at 110-120 (with out an LPR) with 12 clicks on the Dwell. I've shot 2 cases out of my IMP so far and the Gas efficency is getting better. I think that is normal. There is a seat time for new Impys.

BS.

Theres no way you can run an Imp at 110-120....

Have you ever played a game with it?

It doesnt matter what the manual says, you can run the imp at 200 and a little over without anything being wrong.

And if you are running your Imp at 110-120 then I bet you dont hit to many people on the field with that thing...That is wrong....
Turn it up to 180 at least....if its stock turn it to 190......

**djj1973** · June 27th, 08:03 PM

^Well tell me a way to prove it, and I will. Otherwise, take me at my word.

**bunkertime** · June 27th, 10:39 PM

The manual says don't go over 200 cause the micro guages the pball industry used are Required to be within 20% of accurecy. which means the guage might read 200 when it realy is 220. And... the noid that the Impulse ususes has a maximum operatingpressure of 210 PSI, and will cause major damage of ne pressure over 220 PSI.

I highly doubt you can run a sTock Impulse at 120 PSI w/ 12 beeps of Dwell. I call major shenanigans on that smelly pile dood. also.. your avatar scares me

A good pressure to run a stock impy at (like paintbug said) 190 PSI then Set the dwell all the way down, crank it up until you get full shots, then chrono w/ the Dwell.

And please, Don't go w/ Evil parts, they are possibly the worst parts to put on ur gun, Stick to Ndzs. also might wana try out the WAS board by wicked air sportz and the Blind bolt by OTB.

Ok then it appears that you have answered the msytery. If the gauge is possibly off by 20 psi, than that could mean that I am really running at 130-140 when the dial reads 120 correct? That is within the stock specs and not so far fetched.

**bunkertime** · July 12th, 01:22 PM

i did not say 20 PSI, I said 20%

**MuddinPede_98C** · July 12th, 01:34 PM

djj1973, just quit while you're not too far behind.

**djj1973** · July 13th, 09:54 AM

Whats 20% of 100 ? could it be 20 ? 20 % of 200 is 40. Go hit your math books again bunkertime.

**MuddinPede_98C** · July 13th, 11:13 AM

Dude, don't even challenge bunkertime. You are just making yourself look bad.

**djj1973** · July 13th, 11:52 AM

Why dont you try reading his post instead of blindly believeing everything he says. Here I will give you the highlights.

What is 220 from 200? 20 right? And we are still talking about psi correct?

Now assuming that he is not full of crap in his first post, he contradicts hisself in the second when he says:

Read it for youself if you do not believe me.

**MuddinPede_98C** · July 13th, 12:55 PM

He never said 20 is 20% of 200 He said it may read 220 when it is really 200. He never said 20 is 20% of 200. Stop assuming this.

Actually 220 from 200 = 200-220 = -20

So, wrong.

You are the one that said 20psi. He said 20%.

When he said it says 200 and it's really 220, he never said 220 is 40% higher than 200.

So please just leave bunkertime alone. He is only here to help.

I did not say he did. He said that gauges fall within 20% inaccuracy. And in the example he gave, he noted a 20 psi difference from that inaccuracy. He then later denied saying there was a difference in PSI and only a difference in % accuracy. Somewhere he is wrong either his first post or his second post. You are just wrong period. I am not picking on Bunkertime, furthermore, I do not think he needs you to fight his battles.
