Hey all

This is my day which includes the skyline.

Sooo... after work Im on my way to Lansvale to go get my new shadow boost gauge. In sydney it was really warm. I think it was 29deg or something.

Anyway, im driving the hour it takes to get there. And I feel heatsoak on the car, it was just a hot dry day. I finally get to Lansvale and park in the maccas car park, seeing as I couldnt find the shop I thought I might as well search on foot. I get there reverse myself into a spot away from all other cars, and Im letting the car idle for a little bit, doing my noise check. Noises from a car that appear out of nowhere freak me out. Everytime I hear something new, IM like whats that. Haha.

Well a new noise popped up today, this time i thought something was maybe on its last legs. It was a sort of humming in the car, obviously drowned out on the freeway. I did a hearing check all around the car and ruled out the engine bay, yay, and isolated it to under neath the petrol filler, which made sense coz inside the car I climbed on the back seats and pinpointed to the fuel filler. I dont know why it did that, and continued on the way home.

Does anybody here think that the fuel pump could hum so loud you could here it in the car? Any way for me to isolate the problem?

Also I installed my new boost gauge. I like. especially the fact that I can see how much boost im running, the stock gauge is always past 7. But now I see that im running bang on 13 with no spikes :). But I could also finally pin point when I hit full boost. I start building boost at 2,500rpm then I would achieve maximum velocity at 4,000rpm (maybe a little after. The revs jump really fast after 4000 haha, hard to keep my eye on the boost and the speedo.

I have had a tune so I thought (only by reading what other people post) 3,500. Or have been mistaken all this time?

I saw a white GTT tonight on anzac pde turning at the 711 before alison road. Nice wheel chirpies thumbsup.gif.

Thanks guys. And as usual any help is muchly appreciated.

how much fuel was in car at the time, try filling it up and see what happens to hum, yes fuel pumps can be noisey, espicialy after market ones.

full boost @ 4000rpm, what turbos have you got, my stock turbo 32 is full @ 2800rpm and the 34 with -7s is 3200rpm

Tank was about a 1/2. And once it cooled down I tool the car out for another drive and the noise is no more. I read somewhere that heat can cause this, at least I know now. Not like oh shit the cars gonna blow up hahah.

That's the problem, tried to identify turbos bit need to take all the intake piping off :S. Other than that all I can see is Garrett r.42 m24. Which doesn't say alot :S.

ok so, glad sau is back up and running :). but during that time, i went and tested gauge, and car was running beautifully, which im glad.

I have come to the conclusion that i do hit full boost at 4k, tried my best to look at the turbos, but only saw this

Thats all I see, with the big garrett letters on the topside. :S. Cant wait for my service to come up so I can ask the mechanic to have a looksy.

Coz if what youre saying is true, that full boost is around 2,800 then I want to know what these babies are so I can crank them up :P, seeing as im only running 0.9 bar.

Any one else wanna chime in on when you hit full boost with stock turbos?

Thanks

By my searching and asking around, Ive heard anywhere from 2,800 - 3,500 RPM. hmmm, booking the car in for its 90k service the weekend after next. Hopefully the mechanic can get the tally plate number for me. Are there any other details I can get off the turbo?

Sorry to be a nuisance guys. Just very curious :)
