awesome, thats exactly what i want!

also gotta order my apexi ECV to shut it up a little more when i need it

yeh.

but be careful with the ECV. if you decide to one day make your way down here for a tune and advance the timing, you wouldnt have much use for an ECV.

if you close it your changing the velocity of air flow through your exhaust which WILL lead to detonation/Pinging with WOT.

and if you go the Kakimoto R, be sure to get a bigger wastegate flap welded onto the rear housing as there is NO restriction in the exhaust, you'll suffer from the boost creep problem im facing..will have to pull the turbo out again some time soon. I think scotts gonna put a spanner through my head one of these days lol

I haven't had a good look underneath yet, it was fairly dark when I picked it up, but looking at the pics on Andrew's camera, I think I know what the problem is... I think he 'forgot' to put a muffler on the back...

you shouldve gone a Jazma cat back system from Jap and had your exhasut shop make up a dump/front pipe.

mine is 80mm straight through from the turbo to tip. and its still really quiet.(FWIW) .. lol you can actually see from one end of my exhaust to the other lol.

Aaron, don't quote your exhaust as a "JASMA cat back system" as those who don't know it is a Kakimoto R may try searching for a "Jazma" brand exhaust.

If a cat-back has JASMA accreditation in Japan, it just means that when held at 3000rpm, the exhaust sound is under 95dB.

I'll video it tonight..

even cam's noticed it and Cam's picky with this stuff, but he even said.. for a straight through its fairly quiet.

sounds nice on full throttle as well.

Yeah, it is about the same volume as a Fujitsubo Legalis (~90dB) and a touch louder than my Nismo

If you really want quiet, you just cannot beat a Blitz NUR for NM35's.

if you close it your changing the velocity of air flow through your exhaust which WILL lead to detonation/Pinging with WOT.

please explain........

lower velocity will just create a blockage and the turbo cant come on boost as hard/fast. how will that cause detonation??

you decrease the airflow.

if i put my previous exhaust on, with this tune I would detonate because these is not enough flow.

when you advance timing. you advance the amount of air. why do you think i changed my exhaust? I maxxed it at 230kw lol anything more i was detonating.

how do you know why I changed my exhaust? lol I changed my exhaust coz I maxed it.

i was running 20psi fine with it at 230.

I changed the exhaust and went back for a tune and got 285 with 20 psi on 98ron.

ive not maxed my internal wastegate with the amount of air the cars pushing through. and its creeping.

do your EVC valve and tune it Wide open. then close it and do another run with the same tune, and tell me what happens.

if i close the valve then less air out the back of the turbo = less boost = less power.

there is less chance of detonation with less boost, assuming youre tune is ok on the higher boost setting.

why am i silly?? lol

when i get home at 3am i dont want to wake the entire complex and shake my villa to pieces. also when im cruising and see police, i dont want them pulling me over for that.

yes, it will give me a power loss, but if its there soley for the purpose of keeping it quite, why would i be revving the shit out of the car while its in the closed position. i may as well just hand my keys over to the police and ask them to take it.

Thats exactly how I use my Nissan Sports Muffler :thumbsup:

so im not so silly now am i aaron? :P

dunc, i have the sports muffler on my car at the moment. i wired the valve open! not that it made a HUGE difference in sound anyway

so really your a mexican.. shouldnt that mean you live in Victoria?

lol

You'll find that you wont need the valve if you went Kakimoto R u wouldnt need a valve.. you could use it for something else :nyaanyaa:

I find it makes a fair difference on mine, dare I ask are you sure you opened it up the whole way? bigkevracer was in my car for half the SA Stagea cruise on the weekend and thought the exhaust sounded like it almost had a slight leak at 2-2.5k RPM when on the highway cruising..I dropped it into silent and I think the reaction was basically a 'Well, yep. That switch is definitely working, and you definitely dont have a leak'. Stealth mode ftw :ninja:

i've got an ecv

its pretty useless

yes it does make the car quiet with it closed, but it also doesn't drive real good

its fine at idle and low speeds (like 20kmh) but its pretty useless so i don't really use it at all

    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly. 
    • That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
    • I'm interested,do you still have it?
