A turbo sitting on your exhaust pipe has literally nothing to do with engine smoothness. It may quiet down the exhaust note, and it will remove some high frequency components, but the harshness in the motor won't disappear with FI...

They didn't do any suspension work. That's the GTM garage and a stock Z with turbo. You can even here the engine is lower compared to other vids. The only turbo I've heard that's louder than stock is that one they remove the muffler to install.

I didn't say disappear I said smooth it out a lot... anyway red zed. the turbo is placed at the exhaust but there is a lot of prep that goes into the engine to make that turbo operaiional and reliable. But ok red. U know everything.

Let me just correct one thing. I been saying turbos. I should be saying twin turbos. Single turbos have a different effect. That part is my bad.

The harshness won't dissappear but it might abate some of it. I know when I added my CBE and Injens, the engine was not quite as harsh above 6k but it certainly wasn't smooth. There was a noticable improvement, though.

3:12 is were he mentions suspension smoothness relative to his car.

Sometimes, if you build your engine. On that install, they changed nothing internally. Same with most installs. Most people can't afford to actually change the internals substantially on their engine for an FI build.

yeah, you drowned it out:roflpuke2:


The roughness is due to really poor balancing on an engine that is stroked out way too far. Unless you changed something internally, it is still going to be there.

That's probably it. A lot of the audible harshness is gone with the exhaust and intake noise, but you can definitely feel it.

With a proper exhaust and you add a TWIN turbo you (not single) you will hear a lot less harshness in the engine. It won't go away, but it will reduce.

how will that help internally balance an inherently unbalanced engine design?

I don't think the 3.7 has been stroked out way too far yet. There's a lot of Z's out there stroked out to 4.2l. Yes they need a cylinder sheath but they are doing it succesfully. I think this engine can safely go to 3.8 or 3.9.

Urethane motor mounts.

Not really sure how that will help, though. Like Dan is saying, unless you're building (and balancing) motor internals, I don't see how just forcing more air through it is going to make it feel any smoother. Power delivery will feel smoother, yes, but the engine itself should still feel pretty much the same at high RPMs.

Now, with the added rush of another 100+ whp, you probably won't be focused on that at all. It could just be a psychological effect.

:confused:
'cylinder sheaths' = sleeved cylinder?

Urethane motor mounts will help how?

Yes...cylinder sleeve. My bad. Thank u.
I'm working and texting. Thoughts are on the fast.

roger. you used the same term in the other thread, just wanted to make sure we are on the same page here.

Where I work we have sheaths for certain equipment here.. iim just buggin. Lol

:eek: kizz my azz

Besides, the IPL G doesn't come in a black cherry of any sort. At least not on Infiniti's website. Just saw grey and black.

My dude... they call it some sort of black... but IN REAL LIFE. Not magazines. The metallic flakes are not shiny metalgrain silver. The metallic flakes are metallic red. So with light refracting from the car, its black with a red hue. To me, that is what I grew up knowing as black cherry. The black cherry 370 is closer to a maroon.
As far as the silver ipl... I never seen it in person.

My car's color is awesome. I kinda wish it were a bit more maroon, but I love it just the same. There's no shortage of hate for it, though. :roflpuke2:

Naw BC is nice. I like the color. I'm just saying calling it black cherry was a dumb move.

Awesome when it's clean, not when durrrty. :stirthepot:

U jelly of my pollen green accents?

...yes

So jealous. Wait 'til you see my shizz tomorrow. :hello:

Oh I thought that was birdsh1t green... lol

I don't know what I'd do if I ever saw green bird sh1t. :bowrofl:

lol dude, no joke, my car attracts birdsh1t like no other. You're right, instead of "Black Cherry", they should have called the color "Bird Crapper Maroon". :roflpuke2:

Oil additive.

That's not exactly what comes to mind when I think of "ester."

I heard green bird poop in your oil gives you a better drag coefficient.

rep

Shado you're car's color is Shadurple, not Black Cherry.

:bowrofl:

White bird poop is more just for looks, not very functional.

I know that's true, but I still can't haz ppl trash talkin' the pimp shade. :icon17:

:ugh2:

:owned:

:shakes head: from one guy driving "one of the 78 shades of grey" and the other guy driving "the color that becomes mustangs".

Im still mustang-free

That's not the Z's fault, man. :roflpuke2:

Hey mine is exclusive! No one else has a b1adesofgray Z, no one!
