Gen-V V8

Ok, so right now I am almost 19 years old. And so far I have wanted this car for over a year now. For me its the get a V8 or go home attitude. (nothing against the V6 group, it truly is a remarkable engine). Anyway, I have been saving my money as best I can, why keeping my truck on the road. I now have about $5,000 saved, and am trying to accelerate the rate that is going up.

Anyway, to get to the point how long does everyone think the LS3 is going to last. I remember reading threads a few months ago about the Gen V v8's that were supposed to come out around this time, (2009 or 2010) but have been put on the backburner. Im my opinion, this is the perfect time to come out with a new V8 with better gas mileage, and honestly if you need more than 426 hp, you probubly dont care to much about the mileage anyway (So give us less buck for the same bang) . So is it worth buying a used 5th gen V8 withing the next 2 or 3 years, or is GM going to bring out a new V8 possibly direct injection, that will blow the LS3 out of the water in efficency and power.

P.S. please dont remind me about insurance payments for a 20 or 21 year old, I already dread the day. (and I do work and pay for everything myself)

Back when the first news came out, the Gen V V8s weren't going into production until 2011. We've seen contracts that prove that. And you know the trucks and the Corvette would be getting them first...the Camaro probably won't see one until at least 2012. And that's assuming they haven't been put on hold like you said.:(

Long story short, if you don't mind waiting another 4/5 years, then wait, otherwise don't hold your breath.

Also, the new engines probably won't be anymore powerful than the LS3. They'll most likely use the Direct Injection technology to increase efficiency and reduce emissions while maintaining current power levels in a smaller displacement motor. Think of a 5.3 or 5.7L 380horse, 25/26mpg Camaro or something...that's their goal, I believe. fwiw...

I'm very excited about the release of those engines. Does anyone know if they'll be pushrod or would they possibly be OHC?

Thats what Im hoping for, more efficency, same power, anyway 4-5 years seems like a long time to wait, and Im more than happy with the LS3.

Thanks for the reply.

No idea. There's conflicting info leading to BOTH. That is, some variants with ohv, and others with ohc. But that doesn't make any sense...

I remember reading an article where a manufacturer (GM, I think...) was using electronic actuators to open and close the valves, eliminating the need for valvetrains that we see now; all controlled by the engine controller. I don't know that the article was saying that was Gen V technology but I think, from what we've seen, that it'll be what Dragon' has posted. It was a cool article though.

I've seen articles for Ford working towards this as well .. if done right it could be a very very cool thing .... Tune to the application needed

Just brainstorming here, but would it not be easier for GM to just take the 3..6 liter direct injection 300 hp motor, and make a 8 cyl variant of it? By my calculations it would be 4.8 liter and 400 hp. A bit more elaborate, but possible would be a V10 version at 6 liters and 500 hp (great for the ZO6, and then detune it to for truck applications).
Just brainstorming here, but it seems GM needs great technology, while at the same time, needs to watch its R&D budgets.

I may or may not get a gen V 5th gen. Depends on when it comes out. I will be ready to buy my car in 2011 or so. I might wait 1 MY for that engine but no more.

That would (sorta) work with a 90 degree V6. Not so much with a 60 degree.

Yeah; wasn't that the case with the 4.3 - it was a 5.7 with two cylinders lopped off? It needed balance shafts (which it eventually got) but that makes total sense.

I also remember reading about a stillborn V10 based off an LS1 that made boatloads more power that the 454 truck engine (even the 496 later.)

If I have a choice, later, between an FI Gen IV or a NA Gen V, I think I would go toward the Gen IV. I'm all about the brute power and if it takes the Gen IV to get me that, that's the direction I'll go. It will be an interesting next few years in so many ways

One more reason I'm glad I have to wait for the 2012 MY... possibilities of a new GEN V beast. I remember reading an article where it was pushing 450 horses in an Escalade.

it better be pushrod... sorry just don't want any OHC/DOHC. i'll stick with the legendary pushrod small block v8, best engine ever made.

just my opinion.

From a strictly performance-oriented perspective, I would be excited about the new technology if I wasn't so concerned about the lost aftermarket. If they start the Generation V too soon, then some aftermarket support for the previous Camaro platform will be diverted, resulting in a strongly supported 2005 to 2009 Mustang and a somewhat supported Camaro. Don't get me wrong. I think that the Camaro will make a splash regardless of when the Generation V is released. I just think that companies will focus on the new technology, leaving those behind that are using the old technology. This is exactly what happened when Cobalt LS and LT owners with the e16a ECM were abandoned by such companies as HPTuners because a new ECM was implemented. The 2007 tune was created long before the 2005 tune, and many tuners traded their Cobalts rather than waiting any longer than the 2 years they had already waited.

Wouldn't that improve Horsepower as a result as well, less loss, like getting a lighter UDP, getting rid of power steering, A/C, etc.

Hmm... Maybe it was BMW then. I couldn't tell ha' because the article was in GMHTP but they didn't report on what company it was. Learn something new everyday

The VQs have 4 cams that are all driven by the crankshaft. Their new thing is an electric motor that varies intake lift so it can cruise with the throttle wide open for higher efficiency and better "throttle" response.

http://www.nissan-global.com/EN/TECH...VEL/index.html

I think that their variable compression is a much cooler initiative. When the turbo(s) spool up the compression can drop to allow higher boost, but it can run higher compression at low loads for higher mileage and lower emissions.

I'm very interested in the Gen 5 V8's. If they're the same displacement with more power and fuel efficiency I'll be very happy. However, with the push for fuel economy so high, I expect the power level to be the same with smaller displacement and much better fuel economy. If that's the case, I don't know if I'd rather have the LS3 for displacement, or the Gen 5 for its DI advantages.

If it was the same power/torque, would it really matter that much what the displacement is? The way I look at it is, we can't keep increasing displacement...at some point it becomes excessive, and somethings gotta 'give'. A nice 5.3L or 5.7L ~400hp/tq engine and 26mpg (in a Camaro or G8 sized vehicle) would be great, imo.

I tend to agree with you, and besides, the LSX and other crate engines are always going to be out there for those "special" occasions.
