GeeTR....yeh I tried to post up the ".amr" file but it said that I do not have permission to post that file format. I'll see what I can do - I'll try to get some better sound as this batch didnt come out too well on the mobile.

If none of you guys have come across that sound with your GTR's then it may quite possibly the oldish foam of my pod filters making that sound when boost travels back out through them. I'm yet to drive around the block with out them.

All you guys who replied....you all actually drive GTR's, right? I've been through some threads on here where idiots who drive their mummy's commodore put their two cents worth into topics - oh man, they know SOO SOO SOO much about those "4-cylinder" RB26's...oh yes they do!!! They should be shot! LOL. .....the threads end up turning into arguments then. Quite amusing to read - but also quite painful when you're looking for info.

....anyway, just wondering if any of you guys have a idea around why my GTR doesn't flutter even with NO BLOW OFF VALVES. If you guys could perhaps explain that to me that could help me solve my other *noise* problem.

All you guys who replied....you all actually drive GTR's, right?

I'm a proud hippy vegan hitchhiker bum, but i once slept under a HPI magazine, featuring a Daihatsu GTR with RC26DETT... so i definitely know what your talking bout brother.

No idea why your setup flutters under partial throttle, but not with your BOV's sealed up... but then your mechanic suggested you have a external gate hooked up... so anything could be possible :D

Zip and post, or just change the file extension.

Edited by GeeTR

it's normal. with the pods on sometimes RB26s will make a sort of bark/cough noise when you back off/change gear. I think it's the combo of the blitz valves and the pods. just part of the symphony of noises you get from a twin turbo 26.

Ah finally! Beer Baron....someone who actually knows about the sound! Yes, it sounds like a funny bark or very off / broken blow off valve! So we're partially on the same page there but unfortunately it has nothing to do with the valves as I have taken them off completely and it still makes the sound! Pretty crazy! ...but it does rule out the bov's.

I've had another idea at what i could be though....it may actually be air rushing past the plumb back / recirc pipe that is still attached. It is punged up at the BOV end.

I'm thinking of when you blow over the top of a tallie or something and it makes that trumpet sound. I think that could be happening with the plumb back pipe where it's attached to the turbo inake pipe behind the afm.

Yep, go the symphony lol...just not this 1 sound haha i dont like it sorta...i swear, i like all the other sounds lolz!!

Tom

Fly12n, finally some more people who know the sound hehe! Took a while lol!

OK, well if it's all normal than that's ok I guess ;-)

Do you know where the noise is generated from? Is this what "flutter" (or, oi-uleh-fully-sic-flooder-maate) sounds like with two turbo's? If you think about it you couldn't really get that chuff-chuff-chuff-chuff-chuff sound with two turbos...the two turbos would put out something totally different???

I'm thinking that this may be it because, when I run no bov's it still makes that sound.....that's BOOH sound (lmao)

Tom

LOL at the omguleh's!!! Hehe...um yeh I've been thinking about that. There's a fair few threads on big single conversions on here. There's a bit to it with the GTR's and I may have to save up just a little bit lol! About 6 to 7 g's

But yeh I'm not gonna ask about it in this topic...there's already sh*tload's of threads on it by Beer Baron and the likes - actually the one by him is quite an extensive thread.

seriously the noise is normal stop being a f**king pedantic flamin mongrel

Whats with the anger, its a legitimate question...? :)

Anyway, twin turbo upgrade FTW, there's even a group buy on twin's for just over 2K + installation....

Gareth, ah dude doesnt worry me. It's always hard trying to suss stuff like that out. It's no use to take the thread any further without posting up a high quality audio recording - so I'm gonna leave it just for now. People I've shown so far here where I live are stumped by the sound - even those who know quite a lot about GTR's and work with them everyday.

I'll try to get something on the weekend - perhaps I can email it instead to the highest bidders lol.

But yeh as far as the turbo upgrade goes...hehe, mine's all stock...it doesnt even have an exhaust. But, I bombed my old GTST out so far....I went to court for it and everything. Hence my new GTR has been left pretty stock.

there was no anger in my post dude. he asked a legitimate question and got severl legitimate answers mine was one of them.

and tom u should go sick on the gtr bro, i sometimes wish i still had mine. but when i get my s15 soon it will all be forgotten about lol

It's ok guys...she's all cool.

S15 - nice choice man! There's a silver one getting around where I work - goes hard and sounds to match!!! Very sexy!

Yep, I'll go sic on it once more I reckon - I mean why not, gotta have some fun with these last barrels of fuel hey? Won't be able to afford it when it starts to run dry - and I don't think I'll be converting the GTR over to hydrogen!!

I have my first track outing very soon - it should be fun! See how the stock GTR goes against the other boys ;-) It will probably make me wanna do some work on it too hehe

Tom

Julz, for sure man - she'll be fresh as. Just going down for a mess around and see what I make of it. First time mate. I downloaded my asaa license form today so in the next month or so I hope to go for some laps....wed or sat arvo sprints is the event.

It should be a good day out...so far I've just been out in the gokarts (big carts) but not with a car. The GTR is just a bit gocart so yeh - should be great fun provided I don't spin out into the wall ass first!

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to it's full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so damn hot in there, that made it all the more easy to remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. I was standing there looking at the car and said 'f**k it'. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
