HI Guys,,Just got car back my car from Kelly Moss, with their add on in line Bosch 044 fuel pump kit install...Is it normal to hear that pump working/running at all times ,as I do now??..You can hear clearly while you are at a stand still at idle,,,the sound does not change at increased RPMS... But when you are moving/driving and RPM speed is above 2500 RPM,,,the pump is drowned out by the 'OTHER' noises.....They did a nice install/placement and it is under the car and the stock fuel filter has not been moved.....Tony/EPL did manage to get some more power and keep me in the safe injector duty cycle range now...My boost is now 1.4 with some peaks at 1.5 with 93 oct. pump gas with the outside temps of around low 60s/clear out,as was the dyno room when retuned.....Thank You and have a great weekend......

 

Lets hope it works all the time... yes it will make that buzz sound... sometimes its good to isolate it... use rubber grommet to prevent the vibration...

 

HI Mark,Thanks,,,It is rubber mounted,,,The sound is more like a supercharger sound at idle,,if that makes sense....Not a vibration sound...

 

Markski,explain why doing a second pump the Protomotive way does not have the same risk of 1 pump failing & risking engine failure due to running lean. Thanks

 

Noise is common with external pumps. You can install them internally but that's going to be more costly.

 

044 is quite noisy in all installations.

 

Not true! I have been in Paulie's car which I believe has a twin 044 set up and my car when it had the twin 044 set up was never noisey.

Hi,Were both of them in the fuel tank then?? Thanks.....

 

Your in Chicago you should look up Marski.

2 separate 044 pumps, external in the Noble and internal in the NSX. Very loud with a constant loud turbine like sound despite multiple attempts at isolation. Removed from the NSX and less of an issue in the Noble because of increased ambient noise.

 

Thanks guys for your input.....So,guess you just live with it???

 

Tell me if this sounds loud to you? Dual 044 in-tank set-up.

Post a sound clip of yours.

 

I do not understand the question...

 

The reason for the noise with the second pump is that it is not matched to the one in the fuel tank.

Just replace the one in the fuel tank with 044 Bosch pump as well - then you will have no noise. We done this on my car - it had the noise and whilst Markski said it was normal we tried this matched solution and it worked.

 

My own car has dual 044s parallel and they make noise.
Intereting find.
