Inovairtech - MAC35

[Nomadic Pirate]

I really like the concept, looking forward to see how it developes

The 8cc seems perfect for a high power .25

[rsterne]

Thanks for the details, Paul.... A lot of conclusions can be drawn, once we know the volume of ~8cc.... You don't specify, but I assume ALL of the air is released during the shot, ie the MAC is empty after firing?....

Based on that assumption, here are a few of my conclusions.... First, the barrel volume, for a 28" long bore in .357 cal, is nearly 46cc.... That means that the 8cc of air released has to expand to 54cc before the bullet exits the muzzle..... Once expanded to fill the barrel, that results in a residual muzzle pressure of about 630 psi if you start at 4250.... That will help keep the muzzle blast to a minimum.... However, it also means that there is only 8cc of air available to produce the shot, and since the pressure will decline (starting as soon as the valve opens) throughout the shot (as there isn't a larger reservoir feeding the valve) that 8cc won't be able to produce as much power as 8cc of air at 4250 psi can.... The average pressure during the first (and most important) part of the shot will be less, and therefore, I would expect the efficiency to be less as well....

Please note, the above is not intended as any criticism of the design.... I am simply trying to understand how it works, and share those thoughts and expectations with others.... I would expect the overall power, at whatever pressure the MAC is filled to, to be similar to a conventional PCP using a much lower fill pressure.... This is counterbalanced, of course, by the other advantages of the design....

If only higher than 125 FPE!!

[rsterne]

A quick back-of-the napkin calculation shows me that the performance is likely similar to a conventional PCP operating at about 60% of the pressure in the MAC.... the range should be between half and two-thirds.... What I mean is that with the MAC filled to 4250 psi I would expect the performance of a conventional PCP using 2200-2800 psi, and most likely around 2500.... My original 9mm Disco did about 115-125 FPE at between 2200-2500 psi, as an example....

Due to popular demand, we have just added a MAC-Super to the product portfolio which will be 200 - 250FPE at the muzzle driving a .45 bullet.
Available early 2015

Paul,

So , MAC super has increased air volume, correct?

I suggest a 9mm that can produce 175 to 200 FPE.  That would be competitive to other bigbores on the market.

might have to take another look at this then

With FPE like that...(200-250) stay away from the .457 dia!I would rec. a .452 or even a .429 (44 mag/special).Leave the .457 up to the 400+ fpe air rifles..In that cal. standard weight bullets are 300 gr +!!!Of course you can find them down to 150 gr in custom molds but it just doesnt make sence to me why some one would bump .005 of a inch when you can buy .452 in 155 gr-250 gr ALL day long.I had  considered a while back of changing my Barrel on the 909s for that same reason.Couldnt do it though,,that gun barrel is too accurate to give up ;DThat was just my 2 cents!

[starlingassassin]

unless i missed it.....havent seen any mention of PRICES.


i would love to have one of these,but price is a deciding factor for alot of us.

[grumpy]

Thinkl he mentioned in the 900 range

[Rescue35]

The gun itself may not be very expensive. I wonder what the "MACs" (cylinder/valve assemblies) will cost each. That could get expensive quick.

[grumpy]

Think he mentioned in chat the other night that the gun will come with 2 cylinders. Not sure how much more will cost.

[rsterne]

I would think that 10 cylinders would be the absolute minimum you would want, I mean after all, that is the equivalent of going on a deer hunt with half a box of cartridges.... The whole point is to avoid having to take an air tank or pump with you into the field....

Paul,

That is great to hear. I would consider that a very reasonable price. I look forward to seeing your new website.

[Nomadic Pirate]

Cool, The rifle looks nice I justsaw the video for the 1st time.

Really hope this comes out, very interesting indeed

[Jeremy1982]

I may look at the 25 cal.been wanting one and if its getting flat traj. then sign me up

[pyroboy33]

I have to ask, so I apologize if it's a stupid question  , but would hand pumping still be a option with these little things? I mean obviously 4500 psi is out of the equation but most hand pumps can go to the 3500 psi range. It seems like it would be pretty easy to pump those little cylinders up......
