hi my name is Keith with BBI designs and this is a how-to video on how to jet your nitrous kit basically what we have here is the fitting that goes into the intake plenum okay if you take the bottom of this fitting here you can drill a five six using a 5/16 drill bit you're going to drill into this fitting okay when you're done drilling it'll look like that this is before this is after then you'll be able to take a Harley jet is the Holley jet show you can see the jet count but read today anyway I'm going to take this hollow jet and stick it inside the fitting there and then you'll use a hammer and you'll tap it down and when you're done it will look like this one here you just tap it in it goes in pretty snug so once you get the jet in my recommendation is to go ahead and throw it on your engine test it out see how it works if you want to change the Jets all you do is you flip this upside down now this is the old style of barb fitting we used to use on the intakes and I haven't went and drilled one of these but they're the exact same fitting it works exactly the same the threading and everything is the same on us so anyway so don't pay any attention to the fact that this is a barb fitting and this is a Union fitting there's still the same thread on the bottom they still have the same diameter hole inside when they start out here's a barb fitting so you can see in the holes on the inside are the same so anyway so anyway you'll take this fitting you'll tap your jet in go ahead and screw it into your intake and you'll test your nitrous to change the Jets I started out with about an 80 jet here and you'll see how it reacts and then you can take it put it in a vise take a pocket screwdriver or in this case I used an Allen wrench here's an allen wrench here the Allen wrench just happens to fit right inside of here pretty nicely and put it in a vise and just tap and the jet will come back out then you can change your jet anyway when you're all done and you get the jet situated the one you actually want to use and you're all done I recommend notching the end of the fitting here right here you can see I've notched this one notch it right here on the end here and over here on this end to notch it the actual fitting the brass and the brass will sink into the jet a little bit there and that will prevent the jet from ever coming out so anyway that's how you jet it then you just put this back in your intake plenum put your hose back on and you've now jetted it basically by adding a smaller jet to this you'll be able to hold the trigger longer you'll use less nitrous all at once and your power band will be longer I believe you'll get better overall performance but you'll need to jet it to each individual engine because our nitrous kits are designed for such a universal use it's hard to just set one particular jet for each engine basically on the smaller engines you hit the trigger you let right off and you've already maxed your RPM on the bigger engines you hold that you tend to hold the trigger a lot longer but anyway this is how the jet kit works currently we're not offering them for sale you'll have to just make them yourself but this is kind of a how-to video on how to do it if you want to fine tune your your nitrous kit check us out at www.imtcva.org dot boost bottle industries calm thanks for watching and hope this helps you guys out
