Motor Trend makes a case for 7.0L V8 in new Z/28 - Page 5

IOMike · 05-14-2016, 06:48 PM

We know about the 1LE and ZL1.

There is absolutely no reason to believe the Z/28 has a LT1 or LT4.

Would be an epic failure. If there was no 1LE (and the last z/28 wasn't so legit), sure.

You are one of off the guys that heard it.

Dgthe3 is right.

All gm has said (via tadge juecter) is that a big inch
LT1 couldnt meet the power goals of the Z06
while meeting emissions requirements. Does a
6th gen z/28 need 650hp n/a? Probably not.
I am sure a mild sleeved/stroked LT1 could put out
another 75hp and meet regs no problem.

Having said that, I think i heard blower whine too.

Anyone saying they hear a blower in that video, is the equivalent of saying you heard a mouse fart during a thunderstorm.

Exaggerated much?

You know, sometimes when I listen to it I hear something that could be a supercharger then I will replay it while turning the volume up and not hear it.

OldJedi · 05-14-2016, 10:22 PM

I thought there were some reliability problems associated with the LS7?

Not hearing it. All in it is devoid of SC whine.

doc7000 · 05-15-2016, 02:36 AM

Listened to it again and it does sound just like the supercharger that is in the ZL1 Camaro, so I am going to have to go with LT4 though with a different exhaust.

It's too damn subtle, could be the sound of the tires, the fuel pump, another car on the track, anything! In the ZL1 videos it's definitive, I'm not buying this half a second "proof" of SC whine in this video. Not saying it's not supercharged, just saying this is an awful evidence to go by.

I think the SC sound people are speaking of is actually wind noise across the front fins of the vehicle.

It can be, it is really hard to tell though I do sometimes when I listen closely enough here a similar sound that the 2017 ZL1 Camaro makes.

Devils advocate......

In the ZL1 spy videos we didn't just see the ZL1 but also the 1LE car in those videos, is it possible that they are testing the Z/28 with both a LT4 and with a normally aspirated engine in it as well (hash marks vs no hash marks)?
