Yo people,

My problem is that my R33 gts is way to loud after hooking my external wastegate up. My skyline has a straight through exhaust which is loud itself, but not overly loud. When i hooked the waste gate up it made such a noise that it pissed off anyone within a mile of me, and honestly caugth me off gaurd. Is there any chance it could be faulty or any way of reducing noise through my system? I can't even hear my turbo flutter anymore, and my flutter was super loud. Vid attached (only sound as i can't film while driving + little skid).

Anyone know of any options?

Is your waategate venting to atmo? If u plumb it back into tge exhast it will sound same as it did b4. Personally i love sound of gate and would never go back to normal sounding skuline again lol.

it is plumbed to the exhaust manifold and boost is coming just infront of the cold side of turbo. I like the sound, but everyone else in my neighbourhood + copperdogs don't. after 3-4k rpm sounds like vtec is kicking in (i have a really big turbo). Yeah it's venting to atmo, not downpipe

harden the fcuk up!

you're driving far too slow if you are worried about noise :rolleyes:

Haha usually i'd agree with you man, and with a straight pipe i could get away with full boost flutters n shit. I actually had a guy have a shout at me when i went past his house, no idea what he said but he looked pissed.i got 10 demerit points i don't need to popo's attention right now. is there anyway to make the wastegate open in higher revs but keep boost up?

oh I see your problem, i'm told FemFresh will help get that last little bit of sand out of your vagina :)

Do you actually know how to help? or are you just insulting people as an excuse to yourself that you're interacting socially?

Go back and ask this guy what he said, then ask yourself what interacting socially is after you get out of hospital, moron.

Dat cool story, internet intimidation.. please. once again you're not helping, how does it feel to be a literal waste of space?

So you are running straight through pipes and you don't want attention from the police??? Put a muffler on it

i've seen a few people in japan pull baffle's out of there muffler and it reduces sound very well, do you know if/where we can get them in aus?

Plumb it back into your down pipe. You stated you liked it before doing the external. Pretty much answered your question. Venting to atmosphere always creates more noise. That's why people do it. The turbo flutter inside the engine bay gets attention. There's a guy on here that plumbed his through the hood with a tear drop finish. Looked different.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
