Exhaust Advice - R32 Gtr - Twins

[discoPumpkin]

Sigh. Ok discodickhead. Please go search a little subject involving pressure difference between exhaust manifold and inlet manifold. Then, after you get your puny brain around that, search the next subject. Exhaust scavenge, velocity and pressure balance vs flow dynamic properties of hot gas. There is a reason the most obvious of all machines, trucks, use large bore exhausts that are short, smooth and free flowing. I know that in most cases, the turbocharger is designed specifically for a particular engine capacity and configuration as not having a responsive boost control method on the exhaust housing may blow your mind, but the theory is exactly the same. The pressure difference between the inlet and exhaust manifolds need to be different, the less pressure in the exhaust manifold, the faster the turbocharger can compress, therefore fill the cylinder and in turn, increasing performance and most importantly, response. The more air you can get in, the more air you can burn and get out. Next subject will really rattle you. Volumetric efficiency. Actually, fcuk it. Your a deadset spastic. Just google shart. That's about what your good for.

What an absolute moron, I mean you've had 7 years to research all of this stuff and has it payed dividends do u think... Are u an engineer yet or hell even a mechanic, what r u still doing on an open forum then if u claim to bean expert? U can research all u want doesn't mean theory its gona translate into real life scenarios, but good on u Allan for trying, it helps with your autism. This is my scientific explanation, hope u can understand all the algebra etc...

my set up is - R34 dumps, Nismo Front pipes backed onto a 3.5 mild steel exhaust with a single hooker muffler

Only thing i will be adding is a hi flow cat 100 cell - The in cabin fumes from the de cat are quite unbearable...

Sometimes I wonder why the human race is so fcuked. Then I realise that people like this guy breed. Sadness ensues.

Must not be driving fast enough

[33GTRV]

I don't claim to be an expert. Actually, I don't claim anything. I just make funny cast iron and aluminium components go bang bang bang really really fast and make some funny number when I attach them to the funny wires and computers and stuff. I do it all with a ball point pen taped to the side of it.

Please for the love of god, someone invent a way for me to backhand through the interwebs so I can get this kid back to doing dishes and taking rubbish out for his parents.

haha is a strong smell the norm? Seriously smells like i spat out a litre of V power into the back seat to soak in.. that Hole in the bottom of the R33 boot (unsure on others) does not help...... Need to bung that up

Dunno man. I have no problems inside the cabin. Only smell is from the arse end when outside.

[33GTRV]

I dunno Paul. I've heard your arse end can be umm..... Overpowering

[Piggaz]

Smells sweet

Sorry if I offended anybody, really should stop my drinking and internetting

How dare you bring logic into this discussion you heathen!

[discoPumpkin]

waits 4 #@XGTRX to lecture OP on "cams" and "revs" lol

[sultanaz]

Is this guy 4 real? So why u don't have a 6 inch exhaust then? that's the million dollar question on everyones mind because according to your theory absolutely no backpressure is the key to HP and at the same time you don't loose any response, omg omg, I'm calling my tuner tomorrow to get him to put the worlds biggest exhaust on.

So tell me then whats stopped u then I wonder from putting on a 6 inch exhaust like u say considering how much extra hp you'll gain from all this "no backpressure" wizardry

But instead you'll be spending thousands on cam shafts, cam gears, springs and headgasket for your "weekend GTR"- ok cool. Might I ask how many km's this 20 year old beast has accumulated?

Its not that bad. and my weekend gtr is my fun car.. I take it on the track / drags too... and i've driven 12000kms in less then a year in my weekend car FYI.

Just to proove how far i drive kinda thing lol.

75000kms roughly but u no what imports are like... It is quite immac though... Genuine paint/ great interior.. Who knows.

[sultanaz]

Sigh , tried to make my first post as easy and professional as i could and its just turned into shit by a bunch of people fighting n talking shit.
Not all of you but fark...........

[MBS206]

It's only one person who has turned this to shit.

There are reasons you don't go so big of an exhaust discoprincess...

[XKLABA]

What difference did you notice exactly going from the HKS dumps to R34 one's?

A few hundred RPM in response, not really that noticeable, but the flat spot when the wastegate opened was for me atleast

OMG r u 4 real PLS GO!! THATS THE VERY THING I WAS DISPUTING U IDIOT, I WAS THE ONE SAYING THE BIGGER U GO THE WORSE OF IT IS WHEN IT GETSTO BIG, LEARN TO READ, GO BACK TO THE NA forum where ya belong babes xo

To op goodluck with the build, let us know how it comes along

[GTSBoy]

And he's still at it.

[33GTRV]

Ban stick?

[discoPumpkin]

Oh i wouldn't go that far as to ban u Allan, but certainly a break from cyberspace and take ya meds 4 a while and then diagnose the condition/s and go from there ok. Have nice day son
