Not about being cool.
Just a bit of fun really.
Would have assumed the 300c be a little quicker!
Why would you assume that?
What about the 300c insinuates its anything special?
leave him alone let it go lol
i know its wrong...and i admit i've been guilty..but anyway
the more i think about it...if these LS2 and LS3 engines were more powerful and had more technology, it would cost more right ?
however, i just want more technology in it...like the new coyote engine minus the forced induction.
shouldn't cost that much more considering the technology today u know.
Leave the premium engines to the HSV range...bigger CC don't mean **** on a premium car without the tech behind it in my opinion.
exactly what tech do you want?
variable valve timing
double over head cams
DI maybe new
but the other two arn't.
theres no Substitute for cubes
you'll be pleasantly surprised when GenV comes out. 5.5l DI motor from the gooses mouth
Except it will not be overhead cam. That said at least it will be alot cheaper to get big power out of it. I would love to see Holden release the 5.5 DI with a charger from the factory, it would be so easy to make some serious power with a cam change , intercooler and upped boost/Tune. The extra 500cc capacity would also help trump the 5l coyote. Oh well i can dream can't i lol.
Well GenV isn't out in america till 2012 'supposedly' so won't water down to us till probably the 2014. Just a guess (scary thinking that far into the future).
HSV are looking at the supercharged LSA as the next motor upgrade till then they say on LS1.
WTF are people so wrapped up in OHC??? Yes they are great for superior valve geometry however the cost of extra complexity and reciprocating mass IMO is largely under estimated. If you are getting the required power/torque numbers out of a single cam motor why build in more opportunity of failure with a far more complicated solution to the problem??? DI is something I'm very much looking forward to in the GenV
Not if the last 5 years of GM history is repeated. Holden/HSV have had drive trains within months of release in the Corvette. I think you will find them in a Holden near you at the earliest opportunity, particularly if Ford kick goals with the coyote.
Well thats even better!! Do you think GenV will be the better performance choice compared to fords offerings?
Unless you are CSP it's impossible to know. My gut feel is there won't be much between them. The biggest gain with DI will be fuel economy although the tuners should have good gains once they get the software sorted out.
i'm not really regarding this whole tech thing to just power.
also fuel efficiency comes into play. now i know having a 5.5L ain't gonna be fuel efficient, but i'm sure have DOHC would not only be good for valve geo, but also compression aswell.
i'm sure if there were two identicle motors, one had DOHC and one didn't, the DOHC would come out ontop.
Because we are not in the 90's anymore lol. I honestly don't care and actually prefer something that is cheaper to modify anyway but ohc technology is way over due for GM, they finally caught on with the alloytech but it seems they are not prepared to spend extra cash on OHC in the V8's just yet.
The location of any camshaft(s) has zero to do with compression. Secondly, just throwing extra camshafts on a motor is not a recipe for success. Just look at the recently superseded Ford Boss 5.4(?). The thing was a dogs breakfast and should never have been released. Further to this, pushrod motors are generally more compact in size and thus easier to package into smaller cars. How many DOHC boss motors do you see in v8 conversions compared to LSX?
Don't get me wrong, I'm not claiming DOHC is necessarily bad - there are many benefits such as multivalves allowing better breathing and vvt etc. The point is not to write off the other just because you can't have the trendy "DOHC" badge on your guard
case in point right there reaper Gm havent gone OHC for packaging reasons WONT fit they do have engines with OHC and have all the tech but why have to build a lot of diffferent v8s when the ones they are using serve pretty much all purposes and package better lower center of gravity
