Injectors have tips that have multiple holes which fuel is injected through. positive displacement pumps, but even these can be equipped with pressure or flow relief devices to control desired output. Now before I have anybody calling me out on this there are lots of different kinds of pumps in the industrial, scientific and medical world and some of those pumps could in fact be looked at as metering flow (i.e. What meters flow is things like valves, orifices, capillary devices, etc. So, you are saying that for a given throttle position, the larger injectors deliver more fuel? What about at idle? I thought the VP44 metered the fuel volume, at a certain pressure and that the injectors just popped at a set pressure. (made by the same people that made jammer nozzles, 8 holes)ĥ0hp, 75hp, 100hp, 150hp, 200hp (? hole, couldnt find much info on them) Smokem 250hp+ (7x14 and up custom order, these are comp only injector)Ģ00hp, 250hp, 300hp, and 350hp. Mach 8 = ~270hp when used with nitrous, 230hp on fuelĥ0hp, 100hp, 150hp, 200hp, 220hp and 240hp (7 hole standard and custom 6 hole injectors available)ĥ0hp, 100hp, 150hp, 200hp, 240hp and maybe some customs in between ( all 7 hole that i know of) Info was taken directly from websites when available.ĥ0hp, 75hp, 100hp, 110hp, 125hp, 150hp, 200hp, 250hp "competion" and 300hp "competion" (most are 7 hole nozzles but they do offer a 200hp injectors with 8 holes) Now to list what each Brand produces and the HP rating THEY give them. Somebody with some first hand experience chime in, and correct all my mistakes.Ĭoaltrain (not being made at this point as far as i know) Y'all just pile any injector/turbo questions and information in this thread. ![]() Like I said at the beginning, I'm definitely not an expert, and I'm still a newb myself, but I wanted to get the ball rolling, even if my information is not detailed, or if it has errors, (which I'm sure it does) that's kinda the point I want to hear different opinions on different turbo/injector setups, and and what worked best for your truck, whether you daily drive, tow, or sled pull. With a wire tap programmer, a 62/+71/14 turbo would be a better application. It will just be very smokey.Īs the last link states, with a 7x.010 injector, a 62/68/12 turbo would be a nice application. ![]() Here's some links to some very good information on injectors and turbos:Īs the first link talks about, a 7x.010 injector will work fine with an HX35, as long as there's not a wire tap programmer being used. Keep in mind, a specific size doesn't mean it adds a specific horsepower it just depends on the injector. (I use 7 hole, because it is the most common injector in a 24 valve - 6, 7, and 8 hole can be used on a 24V) Some of this info is old news to some of you, but I hope it could help some newbs that are wanting to upgrade injectors and/or turbo(s).įirst I'm going to post roughly how much horsepower a specific size 7 hole injector will add: I want opinions voiced, and I want to be corrected if I'm wrong. #2 - This info is probably not going to be dead on or 100% true, but that's kinda gonna be the point of this thread. #1 - I'm not an expert, and don't really have any personnel experience on the subject.
