turbotrana Member 2,586 Member For: 21y 8m 18d Gender: Male Posted 13/02/12 03:49 AM Share Posted 13/02/12 03:49 AM I use MSD Fuel pump boost control part no 2350. It has a provision to trigger via boost but I dont use it. I trigger via ECU. I locate it in the boot along with the relays. YOu dont want any long wires from the front of the car as under the higher voltage the wires can get hot. There are other voltage booster and they are not cheap.I wont be in my office for the rest of the week so cant get you a part number for the Pierburg but it is sold as a performance pump. Check with the distributor, he can tell you.The 044 pump is just renown for doing weird sh*t when it gets into hot weather when used as an exteranal pump. Its fine in colder climates and when used as an intank pump.On hot days with the heat radiating off the road, the 044 can make a hell of a racket to the point of being embarassing. I just dont want to hear the pump. Link to comment Share on other sites More sharing options...

01txr Member 861 Member For: 17y 11m 4d Gender: Male Location: QLD Posted 13/02/12 10:10 AM Author Share Posted 13/02/12 10:10 AM I'm staying with surge mounted at front. The process west unit I have. But if I find it not to be adequate to supply I will go with a larger one at the rear. I already run a oddesay battery in the boot with power cable running up to the starter. I would be running power straight from there to pump via relay and booster. No running extra wires from rear to front. Just have to read up on that msd pump voltage booster to see if it's safe to mount on firewall or if I would have to run it under dash. Meaning running cables in and back out of cabin. Pump will be rubber mounted as per the pw kit. But I'm also going to run rubber mounts between surge tank and chassis. I don't think the pump will be to annoying but then again I have not run a 044 before. I run 4" custom dump into xforce single 3.5" system. Plazmaman plenum , 4" intake into to4z. Will be making a custom 4" exhaust later on after the engine build is complete as well after cv's are done. I'm sure my induction noise will drown out the 044. Just be the cruising and idling that may concern me if it's heard. I like how nice and quite my car is at cruise and idle and are over noisy pumps. Didn't mind the old Holley blues back on my old Henry v8's but now days not interested. Link to comment Share on other sites More sharing options...

Recommends to mount away from engine bay heat. As well the power to pump wires need to be within 1 foot from unit. This will be a problem if running the pump at the pw surge tank. Excellent bit of gear though. Link to comment Share on other sites More sharing options...

Eg water, methonal injection pumps, nitrous or my case switch 2nd fuel pump on. Only $35 US. Back to running twin pumps (billet holley twin unit) ?????Decisions.......Here's the linkhttp://www.alcoholinjectionsystems.com/p129/AIS-1-25-PSI-Adjustable-Boost-Pressure-Switches/product_info.html Link to comment Share on other sites More sharing options...

If you can hear it from inside something's not right. I've got the plazy unit which is the same and can't hear anything from inside. Looking at twins now not really concerned about the noise as I don't think it will be too bad. Link to comment Share on other sites More sharing options...
