Koenigsegg engine
pretty sure GM knows what they're doing with the corvette... You cant make a general statement like that. A cars all about balance not individual components...
Someone needs a hobbyBiggus Dickus"More importantly, such big cube engines gain little by going DOHC - 2 well flowing valves per cylinder is all that is really needed - which is why the LS7 was such a great motor and an "LT7" would really be cool (I want a another 427 Vette) . Doubt it will happen, but boy would that be the shit." quote
This has to be the false statement of the year. According to your statement, a bigger engine benefits little by going with D.O.H.C design. So that means that a smaller engine benefits even less? So all the auto manufactures that are building their smaller engines are seeing little to no benefit and they are still doing it? They should be using pushrods too, right? But that low end torque, huh?You are implying this logic, not me. Please, ask the Lamborghini Aventador 6.5L V12 Engineeres if they ever consider a pushrod engine in that vehicle because it's more compact or it could make close to the same power as if it was a pushrod design.
I bet they wouldn't even answer the question. The aventador probably doesn't corner well or has crappy balance? Same with other supercars that have bigger engines and just ALL of them are D.O.H.C. ??
Most engines, it doesn't matter the size, will gain tremendously in HORSEPOWER with a D.O.H.C. design, They will just turn into a way more efficient air pump that flows way more air in and out of the cylinders and produces more power this way. Most of the area in the combustion chamber is taken with 4 valves instead of 2 valves and all that empty space left on the surface of that area, that is nothing for the cylinder head and motor. That's not even counting the "HEMI" design of the combustion chamber for the 4 valves per cylinder heads that makes it so efficient and awesome. It's just a no brainer for power in the world of small blocks and engines with less than 8 litres of displacement that we live in.
Let's take for consideration a Ford 5.0 liter pushrod engine from the 90's:
It will never make the same power N/A as when compared to a D.O.H.C. Coyote with the same displacement and compression if you start modding both, even if the pushrod engine had the same ECU and electronics, D.I.; technology to summarize.
A 225-240 HP Pushrod 5 liter ford from 1994 becomes 350-375 HP highly modded N/A with the best heads and cam in the market and all the other goodies. Now try that Vs a 460 (more like 500 HP) coyote engine from the factory that will make over 600 Crank HP highly modded N/A.
Who cares that the engine is bigger and a little bit heavier? We are not Formula one drivers or rally drivers that will drive THAT close to the limit and risk losing our lives for an extra 1-3 mile an hour faster in a corner around some crazy high speed track.
What It matters most, for us, street drivers and amateurs racers, is that it has 250 HP more and can spin all the way up to 8000 rpm making torque and power throughout the RPM band and will be a lot of fun to drive. And the best of all, it can be built to pass emissions!! Then, when you finally add boost to both engines you will have one that has cylinders with an extra valve on the intake side and another extra valve on the exhaust side to deal with the extra tornado of air that your supercharger or turbo are producing most of the time. You finally have two camshafts in that engine that are only for higher rpm power, basically the best in engine architecture. You also have better spark flame with the DOHC and other things too.
Since 2011 when Ford introduced the 5.0 coyote, I'm still yet to hear of a coyote owner that wants to transplant a fox engine to their S-197s or S-S-550s to make it lighter and have less center of gravity than the coyote. You will never hear that, you know why? Because they have all the power they want with the coyote and people are happy with the power and balance of the coyote on the front ends of their cars, overall. All I hear is the other way around, people wanna transplant the assassin D.O.H.C. 5.0 to basically anything they can to make it badass.
Just look at the trucks. Which one is the fastest N/A or boosted? F150. Engine? D.O.H.C. Aluminum, Aluminum body. Things that bring positive results and have that amazing truck to lead the way, in themeanwhile Chevy and Dodge trucks are dogs and suck on their fingers with pushrod oil in the Silverado and Ram.
The motor is in the rear of the vette's now, so who gives a damm about a bit more weight? It will always hook, and always be a balanced car because it's a corvette and the engineers can easily deal with that and will make sure it will be an spectacular car. It would gain an extra 45 lbs, but it will make between 150- 300 more HP than a pushrod engine of the same displacement if you account a 7 liter D.O.H.C.. I will take the massive gains in horsepower, with a bit of weight. thank you.
Remember, The pushrod 6.2L is not making anything close to the power that it could be making if it was a double over head cam design. From my silly estimations, that engine could be making 600-625 hp at minimum in DOHC shape and also passing emissions easier than the LT motor at the same time.
People like that want to hold on to nostalgia even if it means killing the companies in the process...
Who said anything about a V12? Look up the dimensions of fords 5.2 v8. Now try to ad a little over two litters of displacement to that. You dont need 7 liters to make power. You can pull 800hp out of a 3.5 lt motor. Why ad weight just for the sake of having the biggest engine?
I'm sure Lambo owners are terrified of how tall and big their monster 6.5L V12 engine is and how unbalanced their cars have become with the Tower of Pizza center of gravity. They just can't corner with their cars at high speeds anymore.
Pushrod LAMBO now!!!
You can just look at the old Ford 427 SOHC overhead cam engines to see how big a 7 liter overhead cam engine would be. I realize those are single overhead cam engines and not duals, but you get the idea from looking at them.
And when was the last time you seen a big block in a production car? Again a 429 was a massive engine. Now ad room for the gigantic heads a dohc would take up. Does anyone not understand mass is the enemy of performance? Size and weight will kill a cars hanling dynamics.
rubbish. all these 'pony' cars are good for given the driving talent on display across the fruited plain of the USA is going in a straight line so handling doesn't matter.
Jesus man you just want to argue. The title of this thread is c8 zo6. Not hack & sho wants a big block in a pony car. Im done here.
Today I looked on the internet and I saw Ford SOHC engines in production cars. Not that they came that way. Do those count?
The C8 corvette will need an all new engine to keep going in the right direction. My hobby is called going FAST.
