Rattle/sound From Engine Bay(injector/intake Area)

[AlexCim]

I know there is nothing like actually seeing the thing in real life, but just want to know if anyone has any ideas.

Just replaced the turbo with a GCG last night, results good, but just after any major job you listen for noises. One noise i get is at about 1100 RPM, my injector area (pointed to by a mate) makes a rattling noise like as if a nut was in a metal plate sitting on my engine block.

This noise does not occur in nuetral, only when under load (was against the torque converter)

I cant find anything where it actually is a nut or bolt, but I will have another look. Apart from that, any ideas guys? I am only scared driving with it will be worse then not in the end.

Also, the noise is not constant. Its only happening when cruising or accelerating, not when on boost (also higher RPM)

The noise isnt so much a rattle, but it sounds pretty much exactly like a VN commo acclerating away, that kinda rattle/ticking noise (minus the exhaust noise naturally)

Its quite loud also, loud enough ive never heard it before. To be honest, it sounds like a noise I heard when the car was stock but just a LOT louder and worrying. The other noise I heard on idle with humble (on his car too) but this is something different. I can hear it inside the cabin with the windows up quite easily.

I beleive i have solved my own issue

A note to everyone as well

I have a split dump pipe, it has a splitter in the middle. When the car is just slightly reving so the wastegate is only slightly open, it rattles against the splitter.

I will get it cut off and a new splitter rewelded on bent a bit furthur away from the wastegate

Well solved Alex.

I might have to drop my Stag off to you for a full service & tune next, with a full 200-point safety check!!

Good on you Alex So you have a GCG Highflow now?

[AlexCim]

i am major pedantic about noises, its terrible.

And yes, AMS correct, i have a GCG. Quite laggy over stock, but when it hits boost pulls nice. Stock boost.

i have a GCG. Quite laggy / Stock boost.

Umm, yeah, thatd be right

They are most efficient above 1Bar (arnt they???)

But Im sure once the ECU is done and dyno'd then you'd find it to be Perrrfect, with what, 200awkw?

Mine isnt any laggier over standard at all... although I am running 10 pound. You still on 7 alex?

[AlexCim]

uhh, 7, 8 around that area. My Jaycar EBC is on 100% duty in the high RPM.

Ill tell you what though, even though power doesnt come on really until 4000rpm ish, when it hits....mate for stock boost... it hits. For me to get from 4000-7000rpm in first no shit takes 1.5-2 seconds MAXimum.

Ill grab my mates dad mega Gtech (not the eBay one, the laptop version one) and let everyone know what I am gteched at compared to my calder run of 14.7
