    what HP do dsm 450cc injectors max out

    Ive been researching on injectors and like the idea of going with the dsm 450's for my turbo build, but i looked at other peoples builds and there using huge injectors like 850's and 1000cc and only making like 350 hp. So my question is whats the rough idea of the max on the dsm 450's

    I maxed out(or so I called it) at about 20ish lbs/min on e85. Ballpark I would say was 220-240whp range. I could have squeezed a little more out of them, but I knew I wasn't going to be happy in the end so I just bough new injectors. The rule of thumb in the DSM crowd is 250whp give or take with things like pressure, type of fuel and tune in mind.


    Buy a bigger injector if your wanting 350whp. You ideally want a 20-30% head room in your injector.

      Just because they didn't make monster power doesn't mean they can't. There are 850-1000cc injectors on setups making 600+. The output was probably limited by the quality of the parts in their build. But like toycar said you want to have a little bit extra room so if you do upgrade down the line you can continue to make power without the fuel system being the limiting factor.

        Completely agree with what he is saying.


        Also, just want to point out that e85 uses more injector to run, about 30% more so I did run out of injector faster then you would running regular gas.

          it's not a good idea to try to make 600 WHP on 850cc injectors with a 4 cylinder.

          as for the 450's, what is your HP goal and on what fuel?

              If you're building the motor properly with forged internals, why risk it with 15-20 year old injectors? Save a little extra and get something a little larger... 600cc, perhaps.
              Within reason, having injectors that are too large (and not pushing them anywhere near their limits) is a much better idea than pushing smaller injectors near, to, or beyond their limit. If an injector fails, it'll most likely happen while it's working the hardest... which is when you're at full boost. That's the worst time for it to happen!

                Definitively invest on proper injectors for your build. Just like deevergote after investing all that money into your engine you need the right fuel system. I can help you out with the right injectors. Just sent you a PM

                  Rule of thumb:
                  Whatever WHP you want to make, get injectors double that size.
                  You NEVER want to run injectors at maximum duty cycle.
