GT350R vs 6th Gen Z/28

[Voodooo]

It was meant to increase cooling airflow, not down force. The refresh grill of the Gen 5 Camaro didn't flow enough air to cool the Z/28 stock, so the they opened up the grill, used the flow-tie and it lowered temps by..something like 5-10%..(I forget the figure)

I'm being sarcastic

thePill provided enough proof against the 2014 z28. You people fell for it...

thePill also talked about a GT350 that would slaughter a z28 as well... also dismissed as foolery.

As we can see, not even monumentally historical events can alter their conviction to the brand.

The z28 isn't even capable of producing such laps and speeds anyway... it got murdered... it was a flop both sales and Motorsport.

New z28:

The last z28 needed more tire than the ZL1, can't remember exactly but, I'm thinking 285/305. The only issue with just going with a larger tire is, while the contact patch increases in each corner, the footprint remains the same.

Why the z28 got more from its 505hp was, rubber quality, rubber size and, thePills favorite, a wider track. Something like the 2015 GT has in the rear.

The zl1 had to keep the tires in the fender but, the wheel center moves in when I tire gets wider to stay in the fender.

The z28 increased the track width to compensate for, yes, a poor ratio. On a 112.3 inch wheelbase mind you. Does it need z28 track width? Yeah... every car over 500hp needs to be balanced to the wheelbase.

So, in order to correct the zl1's short comings, I believe the fenders will need extended to support a wider tire on a wider track.

An inch of tire in each corner is good. An inch in each corner on an inch wider track is double dippin'... Just add R rubber...

The GS in the C6 generation still had the base LS3, just the Z06 body, suspension, and brakes, just like this C7 generation does.

Right, but note my parenthetical clarification i.e., GM had a higher output NA option in the Z06 (with the ZR1 positioned as the high[est] end FI variant).

Anyway, the whole point of my post: if GM indeed had a higher output NA option (LT3? ) then I'm sure it would've found its way into the C7GS, and so I'd be extremely surprised if a Z/28 showed up with a different motor - though we did see the ZL1 use a different auto tranny, so who knows.

Side note: Sorry for the late response, was in NYC for my birthday, and yeah, we _did_ go the NY Auto Show, wow, now that's a show! :cheers:

GM did just trademark the "LT5" so perhaps they do have a trick up their sleeve for a 500hp+ NA engine. Perhaps they contracted out another DOHC 4v engine like they did in the 90s with Mercury Marine.

Wow you thought the GT350 would be faster than the 2 year older Z28? GENIUS!
and it's only the 350R that is faster...

But but but the golden ratio...

That would be really interesting.

The 90s LT5 was pretty glorious, and a guy in a local Corvette club (I did a cruise with him once down to Ecklers) had a LPE package on his ZR-1, it pulled so strong up top and sounded absolutely amazing (even though the C4 chassis was a bit of a wet noodle.)

Something like that would fit in nicely, because doesn't it seem like there's a big HP disparity, now with the Z06 moving upmarket and going FI? Just in terms of the Vette (though the same applies to the Camaro), there's LT1 @ 460, and then 190HP gap and the Z06. Seems like a non-FI motor in the 525-ish range would fill that gap nicely (and I recall there being some Ford in that general vicinity )

There was some hubbub last year about one GM brass..(Ruess? or whatshisname) talking about what made the first Z/28 "special" and he specifically mentioned a high revving, small displacement V8.

It'd be interesting if the LT5 was a 5.0-5.3L (either 302 or 327) V8 to compete with the Voodoo. GM has the engineers to do it, and there isn't anything that Ford can do that GM can't do. They just have to not stubbornly hold fast to the "bigger displacement" model they've been following for years.

Just out of curiosity, doesn't ford own the patent to TI-VCT and is the only company to use it? I believe everyone else uses VVT to somewhat get the same benefits.

That's just the acronym Ford uses for its design for variable valve timing. Every company today has some form of VVT, just with a different name.

It's just a fancy term for VVT with two cams that aren't bound to the same advancing and retarding of the other cam.

Independent VVT would be the most accurate term.

I don't believe GM is married to the large displacement. I believe their R&D is all centered around a 6.2L/5.3L displacement small block V8 in varying OHV configurations. It cost a lot of money to cast a new block. I just do not see GM themselves investing in building an OHC engine for 1-2 models but contracting it out, seems like a no brainer from a business perspective.

Now there is talk of the C8 Mid-engine Corvette the ZR-1 "Zora" to be small displacement high reving DOHC V8. Perhaps we could be seeing an early preview of this engine tech in the Z28? Something to think about. GM also stated the ZR1 C8 variant would in fact be sold alongside the current C7 generation for a few years as a high end Halo car to compete with the V12 Ferrari, Lamborghini and Ford GT.

All of the GM chassis designs revolve around the small footprint of the OHV small blocks, a DOHC variant would likely be a packaging nightmare due to the extra width

I have to disagree. The Alpha platform does in fact house OHC engines in the Camaro, ATS, and CTS.

The engine in question is the 3.6L LGX V6, which technically would present the similar packaging constraints as a DOHC V8 would from a width perspective.

As well as the TT V6 found in the ATS-V, and CTS V-Sport.
