A single 1/4" hole wouldn't allow for the correct spray pattern in the cylinder. The reason the more powerful ones are more expensive, IMHO, is that there is more technology going into them. The manufacturer's try and get more power with a reasonable amount of smoke and fuel mileage. It's easier to do that with smaller holes than larger ones. Plus, the larger holes weaken the injector tip so there is more technology needed to try and strengthen the tip from breakage. This is just my opinion.

That's the thing though. The larger the holes get, the more delicate they get. There's not as much material to work with. There's less material to put an angle on to change the spray pattern. There's more of a chance of tip breakage. Maybe Don M will pop in and add something. He seems to be an expert on these things. I'm only 17 so I don't know much. Just whatever I pick up from this place.

Ok, I really don't know but,

I thought they all started life out as standard injectors of one flavor or another and then the size of hole was increased by pressing an erosive media through the existing holes. So the larger the holes, the longer it takes.

Someone know for sure???

Gary to answer your question, I don't know why the price goes up as the power does. Honestly the cost of labor and materials to make these injectors are all the same. Of course the amount of R&D done to higher hp injectors could be more but thats not likely. ATS charges the same amount for each hp level of injectors they sell simply because they don't see a reason charging more for different hp levels when they do not cost more to make. Some guy making EDM's are doing the same thing also.

It's a supply and demand thing. They figure if you want more HP you'll pay more money. If all the injector prices were the same no one would ever buy the smaller ones. ;D<br><br>Then there's the possibility that they won't sell as many of the bigger injectors because they are so hot, and cost more because they don't sell as many of them. This is along the lines of &quot;rare&quot; parts are more expensive than common parts.<br><br>BR - It's good to see that some people don't change the prices according to HP. Can you tell me who does that?<br><br>Chris<br>

It has to do with the amount of time that is required to extrude hone the injector and then get the pop off correct. The large injectors take much longer than the smaller ones. Bully Dog told me once that they spend about 5-6 hours per injector just getting the pop off correct on the stage 8 models.<br><br>Doug

It's not always true though.<br>For a properly valved engine : [ 12 that is for those that didn't know ]<br>The stock 215's are 25 percent higher than the 370 preformance injectors at Piers. <br><br>215's : $499<br>370's : $399<br><br> Go Figure ! <br><br> : Eddie : 8)

Or how many do we have to sell at what price to break even or turn a profit. Assuming that R+D, advertising, and production are all the same across the board for the injectors, You then have to look at how many need to be sold and at what price in order to cover those costs. Obviously if you can sell 1000 of say a Stage 3 and only 10 of a stage 8 you will need to price them differently to cover the same costs. The other principle (cant remember the name)is the same as buying an exotic sports car over a mass production vehicle, It costs a lot more to make because your not going to make and sell as many, which is why they cost so much. If DC only made as many trucks as they did Vipers per year, The price would skyrocket well past the triple digits, making it unfeasible to even build. Just my 5.9 cents

I know EDM's are alot more involved then a normal injector.

bulthisl

Thaen why the high price on the 215's ?<br><br><br> : Eddie : 8)

hellotbone

I know nothing about 12 vavles.

The 215 injector is more money because the initial cost from Bosch is higher. Much higher. Bosch has decided the 215 injector is worth more money than the 370 Marine for the 12 valve <br><br>For an extrude honed injector the the production time is higher the larger the power level goes. More media needs to be used to hone it out and the honing time increases. Time is money. Labor is not cheap. Adding to this, the parts for many of the high HP injectors just plain cost more money.<br><br>EDM injectors are the most labor intense of them all. Many hours are spent making the holes and the more holes you gotta make the higher the labor cost is. Adding to this, our set-up time to just get the fixturing on the machine and dial indicated in, takes more time than extrude honing an entire set does. Back to &quot;time is money&quot;.<br><br>Don~<br><br><br>
