Proof that Motor trend is clueless.
How much does this thing make at the wheels?
I'm guessing it's around 360-380.
I commented on that when I watched it
>>15155768
350 assuming 15% drivetrain loss
>>15155768
359 horsepower and 367 lb-ft according to a few tuners.
the SS needs the LT1
>>15155648
Probably just a typo, big whoop

Here we go again, another thread giving way to shit posting, made by the man himself
>>15155648
I realized Porschetrend was clueless along time ago.
>>15155648
OH MY GOD
EVERYONE STAHP WHAT YOUR DOING
THERES A TYPO ON THE INTERNET
>>15155648
What is the typo?
>>15157316
It should say over head valves not single over head cam
>>15155768
A 15 y/o M5 makes that.
>>15157359
But the Chevy SS isn't in the shop
>>15157337
Oh shit I learned something new. I'm gonna assume the little arms are "push rods" right? whats the point of doing it that way?
>>15157407
It's a lot more compact. Larger displacement in a smaller package, more low end torque.
On the left is a 4.6 with dual overhead cams. On the right is a 5.0 push rod engine.
>>15157365
But the M5 is owned by the Gov't.
>>15157444
fuck yeah everyone should do it that way, no?
also nice trips
>>15157407
simplicity
cost
smaller size
less moving parts
faster to manufacture
in my opinion only V8s should be pushrod.
anything else should be DOHC i4 i6s ex.
>>15157359
And how much was an m5 brand new? At least 3 times the price, and a COMMODORE (not a chevrolet piece of shit you septics try to pass it off as) doesn't need track car level of maintenance to be driven around the streets.
>>15157459
The down side is engines are typically less revvy and its harder to have variable valve timing in them.
>>15157459
they don't rev as high and can only have 2 valves per cylinder. OHC can have 3 or 4 valves.
>>15157464
Who cares how much they were 15 years ago?
You can pick up a decent e39 M5 for half of what you would pay for the SS.
>>15157444
good meme
>>15157459
no, they shouldn't, people actually like powerful engines
>>15157493
440hp 250lbft VS 556Hp-550lbft
kinda hard to compare the 2 here.
a mass produced production engine vs a race built one.
>>15157493
the blown engines are much taller than say a stock LS1.
not sure why a 3.0L is that big to begin with.
>>15157493
hey, that image was made in solidworks
I bought this for 8k USD.
It's a little slower.
But it doesn't look like a Malibu.
>>15157593
The 2016 Chevrolet SS looks better than that, though.
>>15157778
>>15157778
Confirmed for owning a Cavalier, because that is exactly what this looks like.

>>15157884
well, there we have it, some retard actually thinks i am alphonse
>>15157881
Yup, that's carbon "black" under some very bright lights. In overcast skies or at night it's pretty much indistinguishable from a normal black car.
Yours looks mega clean, facelift too. Like it? I've got an Orient Blue 540 wagon for a daily but it's lolauto. Torquey though. Enough to spank FRSes and stuff.
>>15157917
I love it, has some aches and pains due to age but they're getting worked out.
Very jealous though, that and Imola red are very hard to come by here in the states, most are black or silver.
>>15157407
For Inline, like your image, it's absolutely pointless since ohc will have the same number of camshafts. In a V configuration, you get rid of 3 of the camshafts and significantly decrease weight, size, and center of gravity
>>15157974

>>15157974
>For Inline, like your image, it's absolutely pointless
Not exactly, you can still get a compact inline engine.
For example, the ford Iron Duke was smaller than most DOHC engines of it's displacement for decades till a modern one took it's place.
If a modern pushrod inline engine were to be made it would be smaller than the 1L 3 cylinder.
>>15157468
>its harder to have variable valve timing in them.
No, it was just never done. The new viper has VVT with concentric camshafts.

>>15158165
So. Hollowish logs vs twigs
Then not to mention the larger heads and timing hardware
>>15158159
God dammit, my bad, it's the Kent engine not the Iron Duke.
Kent engine lasted from 1959 to 2002.
Think about that for a while, an engine from the 1950s was smaller than most shit in it's displacement till 14 years ago.
>>15158179
>Then not to mention the larger heads
heads aren't any larger than hemi heads or 4 valve pushrods
plus there are SOHC engines with 2 and 4 valves, which are probably the same size as a OHV head
>timing hardware
which a lot of OHC engines dont have? plus it makes more power so its hardly a disadvantage
your argument is retarded
>>15158203
>heads aren't any larger than hemi heads or 4 valve pushrods
They are usually taller because they need space for the camshaft. A hemi head is still lighter than a Honda B15 head undressed

>>15155648
Proof that OP is clueless.
Forgot to capitalize the T in Trend.
shāh māt OP

Typo, my bad.
A B16 head weighs around 45 pounds, B18 is even heavier at 50 pounds, a hemi head is around 37.

I'll look around for the hemi weight but it's around 37 pounds if you use aluminum heads. Steel heads are obviously heavier. Using aluminum heads usually shaves about 50 pounds off a dressed block
>>15155648
Clueless? By what means do you say they are clueless? If they get a car to review. they obviously has to get the facts said to us. What you have exaggerated and told over here is a typo error that can happen to anyone.
>>15158297
>But I dont have a scale to make positive sorry
well at least you tried
>>15158280
people always forget that both GM and Ford had pushrod inline engines up until recently with designs from decades ago.
Only reason DOHC became mainstream was for two reasons.
DOHC was seen as "advanced" [even though it's been out at about the same time as pushrods] and displacement regulations.
Forced induction engines using DOHC don't even rev past 7000rpm most of the time so Alot of the advantages go out the window.
>>15158312
You do realize it was someone else in the thread that answered with the weight, not the OP
>>15158355
I hope you're American, because they're the only country where it's cute to still like pushrods. Pushrods are shit.
>>15158358

It has it's uses

>>15158357
yeah, and that guy wrote ">But I dont have a scale to make positive sorry"
an aluminium hemi head with siprngs, valves and rockers weights almost 80 lbs http://www.shophemi.com/c-1170-ported-hemi-heads.aspx
>>15158372
That weight is for two heads, they sell as a pair.
And the weight post is the only post that user made.
Read who posted what again.
>>15158381
right, one head weights 48 lbs http://www.shophemi.com/p-197-57l-driver-side-head.aspx
still, just as heavy as the apparent weight of a b16
>>15158395
You already posted one that was lighter at 40 pounds per head and cherrypicked a heavier one on purpose
>>15155648
This shit doesn't happen at Car & Driver
>>15158404
which one?
the only head that is lighter is the 6.4 apache, and that prob doesn't include valves or spings
the 48lbs is probably the packaging or something
on average, the gen 3 hemi heads weights almost 45lbs
>>15158416
>an aluminium hemi head with siprngs, valves and rockers weights almost 80 lbs http://www.shophemi.com/c-1170-ported-hemi-heads.aspx
80 pounds for two heads plus packaging for shipping.
Or was that someone else?
>>15157407
don't have to worry about the timing chain so much
how ever their are downsides
like rod flex taking away some of the cams lift
but this can be made up for by using a different rocker ratio
also that the rods being where they are gets in the way of the ports
many inline push rod engines are reverse flow in part because of this
more torque comment is just because most of the time push rod engines don't often go north o 6000 r/pm
>>15158422
r u a tard???
the one that weights 48lbs includes the valves, the pair of ported heads don't
thats where the weight difference comes from
depending on the amount of material ported and how heavy your valvetrain is it is safe to assume that a gen 3 hemi head weights 40-50lbs, and these are modern hemi heads, older ones are surely heavier
so lets assume the weight posted in that forum is correct, the b16 heads weights as much as the 3rd gen hemi heads, and that includes the two camhsafts and valves, because i doubt that guy took the cam holders off the head
the k20 weights as much as the b16/b18, so the k20 head must weight similarly to the b head
so much for hemi heads being lighter than DOHC ones
>>15158491
Apparently I'm a tard.
http://www.shophemi.com/p-816-64l-drivers-side-head.aspx
Here's another one with valves that weigh even less and I didn't even have to look that far. And this is why I said it looks like you just looked for a heavier head.
>>15158501
yeah that weight must be off, the only difference bewteen the apache heads and the 5.7 and 6.1 ones is the bolt pattern and bore size
hot rod mag made a massive article about it, the castings aren't any different
>>15155648
>he needed proof
their journalists are a total joke. none of them can drive for shit. auto journalism is hilariously bad.
it's like art critics. if they could make good art they wouldn't be critics.
>>15158514
yea pretty much, so now you get what I'm saying with pushrod weight?
>>15158523
no, the only pushrods heads that are lighter than OHC heads are wedge 2 valve ones, and you still have to add the pushrods, rockers and camshaft weight, plus 2 valve a shit
4 valve pushrod heads and hemi heads weight as much as OHC heads and the difference between wedge 2 valve heads isn't that big
the difference is noticeable in cars because cars are engineered with reliability in mind, so they need more than enough casting material, but motorcycles aren't, the weight difference on motorcycles isn't that big

>2 valve wedge v4 based on the LS
>130lbs without trans
according to several forums the engine of a cbr1000 weights less than 150lbs, 140lbs being the average
i just dont see the advantage of pushrods at all, the LS is the only exception
valvetrain is not what makes an engine light, casting and material used does
>>15158613
I just showed you a head with packaging that was under 40 pounds.
There were also aftermarket heads made by a company called Dominion that were very light weight being billet.
Till Arao started fucking around with them and became a scam artist destroying the company in the process.
Like I keep saying, all the pushrod engines haven't really had the effort put in to make them compete with DOHC because they have just been "good enough".
DOHC engines have always had weight distribution issues (with a good bit being ontop) so they worked to lower head weight for the past few decades, while everyone who uses Pushrods just go with what worked.
If there were a company that made high end 4 valve engines with pushrods then it would be a different case, but there's just no reason to do it since 2 valves work so well so far and the money to put tooling in wouldn't make sense since the aftermarket will pick up where you left off.
There are way more reasons than just valvetrain yes, but as a rule of thumb, Pushrod heads have always been lighter when it's made for the time and not just banking off a design made 20 years ago (talking about the LS and the current Hemi)
>>15158650
>I just showed you a head with packaging that was under 40 pounds.
those are wrong, the casting for the apache heads are the same as the other heads, must be a typo
http://www.hotrod.com/how-to/engine/ccrp-1210-inside-the-g3-hemi-cylinder-head/
the only difference is valve size and bore
>If there were a company that made high end 4 valve engines with pushrods
a lot of diesels do
>Pushrod heads have always been lighter
yeah, but while the heads are lighter, you still have to consider the weight of the pushrods, rockers and the camshaft, which compared to a SOHC 2 valve engine isn't that significant

They wouldn't have made that mistake for multiple heads.
It's quite a few on the same site http://www.shophemi.com/c-1209-stock-replacement-hemi-heads.aspx
>a lot of diesels do
They need to be heavy to make strength for the chamber, I brought up dominion and Arao because they did till Arao killed the company with his shenanigans.
> you still have to consider the weight of the pushrods
Those are what, 100grams per steel rod? It isn't really that much.
The weight is also kept in the block rather than biased pass the top of the block itself and right around the base of the heads.

Here's the other side, there two cute little pushrods in each cylinder head with their own camshaft. I go in an re-set the valve clearance and balance the throttle bodies once a year and it purrs like a kitten.
1143cc dual cam pushrod twin. 85hp and a lot of torque, revs to 8,000rpm. Heads are all aluminum, magnesium valve covers, COP ignition, I doubt the heads weigh more than 20lbs fully assembled.

The amount of spoiled international students is insane, especially in London, Toronto, Montreal, and Vancouver. I did my BA in London at Western, literally 1/4 of the student population drive $40,000 (or more) cars to school. And the government will pay for all of your medical schooling if you agree to take a northern posting for a few years. Basically, the shut-ins and dirty indians that we relegated to the frigid north of the country don't have doctors in their towns, so the government is forced to incentivize med school.

Nah, thats the whole point. If you rob a bank and try to escape in a fast German car big enough to hold the crew and the loot, then they're going to nail you within minutes, because everyone knows what a BMW or Merc looks like. But if you use a silver SS, then they'll be like "They're fleeing in some sorta Chevy, like a Malibu or Impala or something." and you'll blend in with the thousands of identical nondescript Chevys. Then when you get to the roadblock you'll say "Nah mate, this is an SS, not a Malibu. The masks? We're going to Vancouver for some skiing. Have a nice day!" and you'll be home free.
