I just had to.................................

[2cnd chance]

Understand the braking, handling, cosmetics, etc. would be the same.

For those wanting more power consider the upgradability of each offering, not I want an LS9 or an LS7.

FYI a DI V8 wouldn't need as much diplacement to make the same power. Therefore, making it smaller and lowering weight.



So try a lighter weight 5.5L DI V8 pushing right over 450-460HP at the crank.
Not that I know anything.....



Just saying.....

Now that there's a poll, can we edit it? Prices aren't necessary to determine interest or preference in any of these products.

Leave a comment stating your choice or opinion.

However I think price is VERY relevant to most.

It is still a small block V8. I believe only the combustion chamber would differ.
Any weight difference would be nill.

[boxmonkeyracing]

a DI v8 at 6.2 liters would surely be over 500 hp. especially if 5.5l is pushing 470 in the GT2 class.

[a_Username]

I'm still wondering why people are even wanting a a 500 HP motor. The only thing that is going to compete with the GT500, which we all know will be it's main competition, would be an LSA. Unless they perform some sort of miracle and get 570 HP+ out of TTV6 set-up, the only thing that will be able to reach that sort of HP, at a reasonable cost, would be an LSA. A 450 HP DI would barely be a HP increase at all from the SS...

Consider everything being the same? DI V8 has less parts to break...no turbos to foul up, fail, etc....not SC to throw a belt on...etc.

I'd LOVE to have the LSA. LOVE IT.

[PQ]

a simple tune could get you the DI V8 with an SS.

[Dragoneye]

I like the LSA...in fact, I love it...everything about it is perfection to me...

BUT -- I would buy the SS as it is, if it were called the Z/28. (I'd modifiy it to just under 500 hp, and upgrade the suspension, and call it a day). The raw power is not what I'm interested in, its the handling, and the style. If they make the Z/28 with an LSA...I'll have to "live with the extra power"...how ever will I survive?

SO -- I want a DI V8, because I want that amount of power, I want maximum efficiency, and I want that V8 sound....something a TT V6 can never replicate (it can get close, though...)



(I would like to see all of the above in the Camaro lineup, however...but my vision of a Z28 is relatively specific...)

[SSmoked]

im down with the LSA. who cars if theres extra weight that comes with it. check out the cts-v and what numbers it pulls off with that motor and it weight north of 4000lbs

Yeah, like 300 lbs north.

LSA.

I'm still going to ask how much weight a TT V6 setup will save over even a DI 6.2? How much does each turbo weigh? How much are the cooling lines and related components going to weigh? What - it isn't going to be necessary to strengthen the chassis and powertrain? How much torque is this set-up going to put out?

Sorry - LSA, IMVHO, is the obvious choice (for me, at least). I think a 500 horse' DI 6.2 would be sweet, but unless it looses another 300 lbs. on top of that, I just don't see a significant justification for that over an LSA. That DI 6.2 isn't going to have the torque the LSA will have and this car needs torque. I don't want to have to wind the 3.6 out to 5K RPMs in order to get some good acceleration. LSA makes great torque down low and great power up top. I think DI is the direction gasoline engines are going to go for maximum efficiency, but I think it's going to be several more years before we see it in Camaro - I think it'll be in Corvette first.

LSA

You're thoughts are pretty much in line with mine...with one addition (which ultimately led me to choose the DI V8 over the LSA...)

They will probably weigh the same...and to be perfectly honest, given the advancements, and time they've taken in developing this powerplant, the V8 might be lighter....BUT...compared to a non-DI V8, the TT V6 makes a lot of sense for weight distribution, and fuel economy.

Here's what I was talking about....Cost. Given that the Gen V engines will replace the Gen IVs, production costs will be well-spread out, allowing the DI V8 to cost only moderately more than a current LS3....compared to...12-14k for an LSA? The trade-in is a loss in hp, but personally, I don't need 550 of them, so I'm willing to give it up.

I'm curious what makes you say this.

Have you looked at the LNF's torque curve? (2L DI turbo engine in the Cobalt) I don't think you'll need to rev a turbo V6 from GM in order to get good accel.

hmmm.........

[MikesZ]

Would have been nice to see a 450hp DI VVT motor added into the polling mix.

VVT will most likely be part of the GenV engine lineup...which is what I assumed the OP meant by "DI V8"

[ShnOmac]

Anybody else suprised the one with the most power is winning??

I can see this, especially if they bring displacement down. They'll make it more compact and lighter, like the Gen II was to the LT1. I don't think it's going to be a great a difference because I don't know that there's a lighter intake manifold than the polymer they're using now - unless they go carbon fiber, lol (I don't really think they'd go that way). I think fuel economy is going to be reduced on this TT, opposed to the LLT right now - maybe a couple MPGs. That's still nothing to sneeze at though. It gets better mileage than my wifey's 3.6L Malibu! I'm still skeptical of the TT weight though.

Here's what I was talking about....Cost. Given that the Gen V engines will replace the Gen IVs, production costs will be well-spread out, allowing the DI V8 to cost only moderately more than a current LS3....compared to...12-14k for an LSA? The trade-in is a loss in hp, but personally, I don't need 550 of them, so I'm willing to give it up.

I still think we're seeing the top of the heap, in terms of total power output, with the Gen IV 6.2s; at least the LSA and LS9. I see the Gen Vs coming, and getting into LS7 territory in terms of power, but no more FI V8s. Like you said - not everyone is going to need or want 550 horse'. All I know is that Z28 better have more performance than SS, be it with weight reduction and moderate power increase, or a lot more power and a little more weight.

On the subject of weight, has anyone noticed so many of the supercars out there weigh pretty d@mn close to Camaro and Challenger?... Sure, they make a lot more power, and they're even made of carbon fiber and exotic materials, but most of them weigh so much. If they can make due with that weight and balance handling and power then why can't we do that for Z28?... Just a thought

I'm curious what makes you say this.

Just by virtue of it's displacement and stroke. I think there's more leverage by virtue of the longer stroke and longer arm of the 6.2, but I've been suprised with FI'd smaller engines in the past, so I'm just speculating. I'll totally eat my words if I'm wrong

Have you looked at the LNF's torque curve? (2L DI turbo engine in the Cobalt) I don't think you'll need to rev a turbo V6 from GM in order to get good accel.

Yeah - I noticed that, and it's really suprising. Some of these smaller displacement sixes and fours really suprise me with their torque curves. It seems like GM has nailed this down

hmmm.........

I'm sure it's not too far away

I voted for the LSA for a Z-28 model...I just think it begs for it. But if they offered what my idea of an RS should be (1LE package)...with a smaller DI VVT motor & handling package...I would opt for that over a Z-28.

[boxmonkeyracing]

hmmm guess the DI info out there isn't enough for people to have a good understanding why it's better. and 6.2L DI will put down north of 500 hp with out breaking a sweat. so who knows why people are stuck on the LSA.

[brandotron]

I can't imagine GM putting the new DI V8 in ONLY the Z28. I imagine it'll go in the SS as well, like when the LS1 replaced the LT1.
