Never owned one...
My biggest complaint about the 3.7 in my 370s (i owned 2) was the out-of-breath whine and vibration it made over 6000rpm... reason why i put on test pipes, which « somewhat » alleviated the problem...

so does this TT 3.0 liter engine have a sweet sound in the Q cars?
Also, how high can the block go in terms of Hp without turning it into a whizbang engine? Basically, safe levels of Hp for a daily driver/occasional track car? I tend to err on the side of reliability instead of stellar (but nerve wracking) power Numbers...

thanks!

You'd be well served to browse the Q50/Q60 forums.

The VR30 is an excellent engine.

The sound of it is not as expressive as the VQ37 coupes. You can consider turbochargers as a "pre-muffler", so they tone down the exhaust sound a bit. However, VR30 cars with aftermarket exhaust sound NEARLY as good as the VQ37. It's very close.

Most car reviewers love the VR30, but dislike the cars it is in. Many times it is said that the VR30 has a very linear power band that pulls very well to redline, in contrast to the majority of turbo engines that make strong low-mid torque and run out of steam above 5K rpms. It is a well liked engine, and can pull a heavy Infiniti through the 1/4 mile at 111mph.

The VR30 responds extremely well to the typical mods like downpipes, exhaust, piggy back tuners, tunes, etc. You'll find many examples of VR30's over 500 whp with bolt-ons on the Infiniti forums.

Thanks for the info... And I will go check what the Q guys have been up to...

Only thing is its down on Torque compared to M2 competition engine. Around 56 ft lbs, but then again Nissans launch better

If it truly feels linear I will be happy. That's one thing about turbo engines that can be frustrating. Big toque shove low down that propels you forward but then dies off horribly on the top end. If they can do minimal lag with linear pull up to redline that would be amazing.

I found lots of articles praising the VR30 (and bashing the Infiniti it is wrapped in):
"Despite its turbo oomph, the Red Sport has a linear power delivery all the way to redline."

(1/4 mile trap at 112 is well ahead of the fastest 370Z, despite weighing 3895 pounds!)
"At low rpm, the engine does an excellent impression of a velvety inline-six, and turbo lag is virtually nonexistent."

So, who would guess the new Z will get to 60 in 4 secs flat with the manual?! I know the auto will probably be slightly quicker. Keep the weight down and it sure is possible. This is my hope 😉

Not likely if you need to shift into 3rd to reach 60.
Maybe possible if 60 can be achieved in 2nd gear.
I would expect the 9AT to be significantly faster, though.
I have a 7AT...yeah I know it is faster than the 6MT, but damn I strongly dislike the 7AT!

You're being extraordinarily generous here - let's face it, in the Q60 the VR30 sounds like total @#$%. Nissan must realize that the sound profile for the engine and exhaust will need a drastic overhaul in a sports car application; if they don't make it happen sales will take a hit.

Yeah, sure.... :rolleyes:

You really don't think the way a sports/performance car sounds impacts sales? That would be news to Ford or GM. Without those great V8 noises the Mustang and Camaro would probably be history by now.

Every video review I have seen of the Q60 with the VR30 has commented on the weak and characterless sound it makes.

I agree about sound. It's why I dismiss the impressive Teslas. I have a Q60 VQ37 Coupe, and it has the "Infiniti Sports" upgrade OEM exhaust on it. Sounds amazing.
Of course a VR30 with factory exhaust will be a bit quiet, but it sounds good to me. The turbos reduce the exhaust sound, but when a proper upgraded exhaust system is installed, I seriously think it sounds 95% as good as my VQ37:

Not everyone hates the sound of a V6.

Sounds like even a dealer-installed exhaust system produces some good noises:

Slow shifts or not, we did appreciate the growls from the Red Sport's boosted V-6's exhaust, particularly at lower engine speeds. Running it near the 7000-rpm redline, however, leads to some gruffness. We were impressed enough by the tones coming from the exhaust that we looked under the car and noticed it had a $718 dealer-installed performance exhaust system that wasn't listed on its window sticker.

It wouldn't shock me if the Z ends up sounding more aggressive than the Q60 RS400. In fact, I would bet on it.

Not bad, I'm hoping the same. But also prepared to go the Ark Performance route, great sounding!

With what I've seen, the exhaust of the the new Z looks awfully a lot like the one on the 370Z... I don't know if thats good or bad just an observation.

This is promising. It's likely the same Infiniti Sport Exhaust that the Car & Driver article was referencing. I am hoping that this is basically what comes stock on the Z because it's apparently rather nice-sounding.

"As for the sound … it’s also pretty spectacular. We took the Q60 out to some of our favorite deserted backroads and let it rip with a GoPro attached to the bumper. This particular Q60 Red Sport 400 is fitted with a more aggressive exhaust from Infiniti. It’s an axle-back exhaust, aptly named the “Axle-Back Sport Exhaust Kit.” Infiniti sells the exhaust on its official online parts store — there’s one available for the Q60 and another for the Q50. It’s currently listed for $707 and is backed by the original factory warranty."

Already, you need add-ons...:(
Why do you "need" add-ons?

If you are a person who wants a rowdy exhaust note, then get a replacement exhaust. Seriously though, just because it has the same tips as a Q60 doesn't mean the muffler is the same. People haven't even heard the production model yet and are already lamenting it?

I can guarantee you that whatever you like won't be universally shared opinion and others will be unhappy anyway.

Dude, do your forum namesake and relax... 😛
