What all would deed to be done to convert a 2006 Bangel with M-Pro cams to a nitrous setup.
Current set up is F3 module so I think 26 draw length & 50lb max limbs ( bad shoulder)

Tell me what you think.

You can reach 27", maybe 28" with NOS B cams on a Bengal.

You would need 33.5" cables and a 47" string, for a 32" ATA.

You will also need a longer bottom axle and the spacers and end bushings to go with it.

If you want the cable guard to stay, you only need two modules, with short screws. If you want the X-system, you also need the X-modules with longer screws and 4 single loop cables, vs the two split yoke cables used with a cable guard.

They have been discontinued, but they come up for sale on AT fairly often. The hardest ones to find, are the C cams.

I forgot to tell you. Switching from the M-pro to NOS B, will increase your DW by about 10#, unless you drop two deflection numbers.

I have a set of polished B cams I would sell you.

If I had a 26" DL, I would sell the Bengal and convert an 09' Warthog to NOS B.

The Warthog would have a BH of about 6" and should reach 26.5" of DL. Going from the CAT to the NOS B should only increase DW by about 5#.

will these cams speed up your bow? I have a 28" draw. I am interested in this.

Going from a M-pro, to Nitrous?

Absolutely! The M-pro has a FAR smoother draw force curve than the Nitrous cam.

The NOS cams don't have anywhere close to the let-off% of the M-pro cam though.

I think a bow that shoots 290 at 70# with an M-pro cam, will shoot 315 at the same DW and DL with NOS cams.

what would be the let off? want some more speed but I dont want to buy a new bow.

I have been told that the HL mods give 75%, but I think it is actually closer to 70%.

do you know what cams I would need for a 28" draw? If your set will work waht do you want for them?

That is right, Copterdoc.

Ohjust by the way.. I have two sets of C-Base cams here. With Shoot through mod. ;) :P

Am I opening a can of worms trying to do this to my Bengal? I like my bow a lot and I cant afford to buy a new one just for some speed. I am hopeing this is a good solution instead of a new bow.

Oh... I love the color of your bow....


I'd say that your Bengal will be faster but you still need to get the new parts. Cams, Strings and cables. This will be less expensive than a new bow but still not quite cheap...

I understand that. I also want something different. I can do it little by little. I just need to find the cams. Do you know what cams I would need for a 28" draw? and if your cams will work, how much do you want for them?

copterdoc

If you NEED to reach 28", you should go with C base cams and mini-modules.

I am fairly certain you would be able to get 27" with B cams, and I THINK 27.5" is likely, but it is not something I would bet money on.

I need 28" 27 will be to short. I am 6' tall and 28" is my sweet spot.

You have one other option.

You could go with 14" limbs and B cams, with regular modules. That will give you a 7" BH and 28" max DL.

The C cams with 13" limbs, will give you a 7" BH as well, but the B cams should be a smidgen faster.

where can I get the limbs at? Do you know what size strings and cables I would need?

The limbs are going to be hard to find, since you have the new Roto-cup limb pockets. I don't even know if they make rounded style 14" limbs. I would call Martin and ask. You can use the older style square limbs, but that would look kinda goofy.

You would need 33.5" cables and a 47" string, for a 32" ATA.

For C cams, the cable length would be the same, but the string would be 52.5".

I would be better off getting come C cams and using the limbs I already have. Do you know where I can get some C cams and what else would I need?

I agree.

See posts numbered 2 and 4 in this thread, for what you will need. I am about 90% certain that your draw weight will go up by 5# (unless your current cam position is out of spec). See my last post for string and cable length.

I can't spare any C cams right now, and they are the hardest size to find. You have a better chance of getting everything you need, by buying a used bow that already has them on it, for $250-$300. I think there are a few available on AT right now.

You will be able to use regular, or mini mods, for your DL. The mini mods are two inches shorter at both ends of the range. The reg mods should be 27"-30" and the mini mods would be 25"-28".

The mini-mods are supposed to be a tad faster, but my chrono has never shown that to be the case.

Just for your interest:
As far as i know there are no 14" limbs since 2009. They stopped making them because there was no need any longer for. So there are also no 14" Mag limbs with the rounded ends.

ok, thanks for your help. I have been looking for the cams and I cant find any. I guess it wasn't meant to happen.

I may have a solution for you. I have a set of C cams and I will trade for B cams, so if you want to buy copter's B's I will swap you straight up for the C's.

You guys are on the ball on this one.
There is a set of cams with limbs on AT classifieds but not 100% sure what the guy has. says x and b with strings and limbs but no mods for $125 shot him a PM but no reply.

Copter... what are you looking to get out of your polished B cams?

Unless you want to sell yours to drevilmike77, and buy mine.

B cams aren't very hard to find, compared to C cams.

Would the draw weight still go up 10# using 14 in limbs?
