Reed cage mods or aftermarket cages

[shanYE west]

Here is a lilttle food for thought.. this is a dyno comparison.. done same day.. same dyno, same bike by a unbiased reputable builder with no ties to the products on a 350 drag engine. All reed systems were jetted accordingly. DIR is the mossbarger cages that made a claim to top the VF. Which led to this comparison.

 

Notice the VF produce more power and torque EVERYWHERE.. even over a stock ported cage (carbontec). there is about a 3hp gain even below 7k rpms.. The VF have no problem performing down low. I would like to see some dyno's of the blaster cage vs a VF if anyone has one.

Nice chart. I would be very interested in seeing one with the blaster cages and say tdr reeds on ported stk cages. I would like to add the gains on a stk or say piped motor would be even less imo thats an expensive 3hp give or take depending on setup. I would also think and have been told the ported blaster cages will pu a considerible amount of flow over the ported banshee cages. On the other hand ive been told by some very wise people that the vforce in the end will still out flow any other setup. You can setup a set of blaster cages for around 80 bucks not with the carbon techs though I might give it a try but I dont have a dyno.

I would agree with you on that.. but on the same hand.. a stock or piped motor wouldn't need a blaster cage or a ported cage either. stock cages with some good reeds will work just fine.

Anyone have pics of a ported stock cage? I read somewhere that if you have the dual stage reeds(big reed goes all the way across) that you can remove the center bar as well...

We do agree that was my point but alot of guys will drop 200 on a set of vforces and skimp on something else I was just tring to point that out. If I had access to a free dyno I would figure this out I have been considering picking up a set of blaster cages porting them with tdr reeds for my cub but I cant tell you alot cause im either to cheap or poor to drop $200 on the vforces to compare. Everytime I consider buying them I always think of a better way to spend $200 but im approaching the point where it might happen one day but I doubt it. My motor would proably benefit from them more then most but I need a lock up, overide and im sure a bunch of other stuff that I feel would benifit times more even if I am losing 2hp on my reeds.lol

I have been told that the dual stage reeds will fluter at high rpm. You can remove the center bar but it will weaken the cage.

you never want to cut out the center support. it keeps the large pedal from flexing/deforming. you can, however narrow it down significantly, and remove the rubber near the tip to keep it open. the big things are to really open the windows down to the screw holes, leaving 2mm of material around the screw holes. the nose rib should be long and narrow for higher rpms, and more steep for lower/mid rpm's. the biggest gain on ported stockkers is relieving the area that the petals coushin against, allowing them to seal a little quicker.

 

 

tha graph, is great for portraying the vforce cage, vs the stock/pyramid on a drag ported motor, but that's not what is in question here. and there is a point where the engine reahes it's resonant flow, close to peak rpm's, that the reeds are open almost all the time, and the reed assembly merely becomes a restriction in the flow path. in this case, nearly 2x the opening area will definately flow better. the point of the chariot setups is not simply to keep up or compete against vforce cages, but to emphisize on the low to mid-high flow for those looking for a vforce level alternative in non-drag/topend builds. yes, vforce provides gains all over, same with chariot cages, but vforce is best for mid-top, while charriot is best for mid low, when compared. the chariot setup, ultimately is based on a stck sized cage and pedal selection, therefore incapible of flowing enough for builds larger than 4mill and once again becomes a greater restriction than the vforce cages. this is where the blaster cage comes into play. it can be set to run with power or pro reds to emphisize the mid or low improvements, while keeping a larger flow area @ higher rpm's the screw holes will have to be moved either on the cages, if possible, or intakes. i'm ordering a set off ebay to measure up. i'm sure there is a chart out there somewhere, and if i can't find it, i'm not going out and buying vforces just to run on a dyno. i'd rather put that money elsewhere.

Not sure I follow you

I have a feeling this comment was made because I suggest running carbon tech reeds on low-mid motors. High flowing Top end power motors will make more power with the vf3 setup compared to stock cages with carbon tech high tension reeds. Low-mid motors will make more midrange and low end power with low or mid tension carbon tech reeds compared to the vf3 setups. I know this because I have tested on a crank dyno with the vf3's versus the carbon tech reeds on the stock cages. Midrange wise, the carbon tech setup beat them out by 2hp.

This is what I did.

I use CarbonTech Hi -reeds.

I have heard this as well, but mine was from a builder. I have a set that I ported and made the center bar very thin, I have another set I am working on now on which I am removing 1/4 inch of the center bar, from the end towards the peak of the cage. You do not want to remove the whole center bar but You can safely remove a small part of it.
