I can see why VVT is useful on NA engines, since the timing is optimized to allow the longitudinal air pressure waves in the intake runners to 'bounce' into the cylinder, at any particular RPM. But how come they are also used on forced induction engines? Doesn't the turbo/supercharger completely ruin the rhythm of the pressure wave 'bounce'?
this question is above our pay grade. go ask a real forum
>>17026572
VVT is a way to "cheat" performance out of an economy engine. So are most modern turbos (looking at you Ford). There's no reason not to combine the two.
Wtf? Variable valve timing isn't about "bouncing air waves" into the combustion chamber you fuckhead what does that even mean.
Vvti is used to adjust cam profile to allow for to come in sooner in the cycle, allowing faster combustion. Variable valve tech isn't even hard to understand. Get your autism checked.
Post whatever and I'll see what you've posted in the morning

I like pushrod V8's, but don't defend them like a fanboy. Am I a pushcuck?
I hope you don't wake up.
I am going to buy an MR2 SW20 within the next few weeks.
I want to know what /o/ thinks about it.
>>17025888
RIP OP
>>17025888
I would tell you to kill yourself, but it seems you're going to end up doing it anyway
>>17025888
I have a W30 MR2. Only had it a month now and I'm having a blast with it.
MR2 owners are a bit cultish but really friendly. Don't be surprised if other MR2 owners you meet randomly ask you to add them on Facebook.
Also, don't buy it if you don't like attention. Strangers will always ask questions about it/take pictures of it.
They really aren't kidding when they call it a poor man's supercar.
Why don't diesel hybrids exist?
Because it makes no sense.
I think they're common here in Europe. Fairly sure VW has a TDI hybrid Jetta
>>17025781
I don't know anon but why don't they make an 8 cylinder engine like this and not shaped or straight in a line
Is it feasible to drive across the country using state highways instead of interstates? Seems like it'd be a fun if not slightly slower cross-country method. I'm driving from PA to IL in a few weeks and I don't really want to push my miats past 65 MPH for extended periods of time so I won't be going all that fast anyway.
>>17025576
If you're road tripping you should always be taking the back roads unless you're on a schedule. Route 66 and whatnot.
I think that's the best way to travel for sight seeing
Interstates are good for getting there fast just don't expect scenery and the only place is exits with gas stations and truckstops
>>17025585
how do you find solid backroads without scouring a map for 15 hours?

Odd, don't most manufacturers use a narrower valve angle these days because that's supposedly better for performance?

One was a hit and run the other was my friend passing out driving us home from a nearby college town
In the early-to-mid 2000s they drove midsize Cadillac sedans and SUVs.
What would they drive nowadays?
Escalades or Navigators and black Suburbans for the peons.
>>17024765
Well Ray Donovan is kind of like a 'mobster', he drives basic bitch Mercedes.
But the answer is; whatever company provides them with cars/money for low key advertising. It might be
Lincoln MKZs or whatever they are
Daddylac CTVs
Any Denali
how do know is if shocks are blow?
>>17024705
Push down on the corner of the car, if it keeps bouncing instead of returning back to where it was, it's fukt m8
>>17024705
If oil shocks covered, they fucked are.
>>17024718
shocks can still be fucked, yet still stop the car from rebound. u dumb as fuck Justin.
daily reminder
yurofags need 12 cylinders and TWO turbos to make half this much power
I've always wondered why Euro engines (Mercedes V8s with twin turbos, for example) make literally shit power, unless they're tuned aftermarket.
>>17024639
Because yuros aren't allowed to have fun
>>17024639
because europeans do stupid shit like twin turbo a 3.5 v8 not a normal size v8
a friend of mine bought a maserati quattroporte 2008 some days ago. i thought it is a bad idea. today we drove around in the city. holy fuck was i wrong. amazing car. buy this shit. most underrated/underpriced car.
picture is from google obviously.
>>17024582
Wait until he has to fix anything.
>>17024592
true for cars like this. luckily he took a warranty(not cheap-but will pay off).
With the exception of the Miata, RWD cars are too fucking big. Where are all the RWD subcompact hatches?
Rusted out and crushed because they stopped doing that in 1989
>>17024581
BMW 1-series
>>17024581
>Where are all the RWD subcompact hatches?
RWD isn't viable for econohatches for a variety of reasons:
>drivetrain losses
>reduced cabin space
>more effort to assemble
Basically RWD interferes with everything an econobox needs to do and adds nothing for most people.
wagon > toogay
do yall niqqas even go fast?
Wagons a best.
It's like comparing Daytona Speedway to Nurburgring. One requires an ounce of driving skill while the other tests man and machine.
Do you'll cowards even wangan
Are there any performance variants of the Toyobaru that ehm... have more power?
Lexus RC.
Similar body, just larger, with a fuckhuge gas tank (I think it's like 18 gallons or some crazy bullshit) and all of the Lexus amenities.
>>17024457
Forgot pic.
>>17024462
hmmmm, really makes me think
I just got four new tires and two of them are already leaky. I thought it might be these little filler nipples so I checked them but none of them hiss. I had to roll the car to check the ones on the bottom but none of them were making any noise
what do i do now?
>two of them are already leaky
>checked these little filler nipples
Wat?
I bet if they actually are loosing air it has something to do with the bead. If you have aluminum or alloy wheels and they didn't clean the rim it could be leaking from there.
Pic related. Perfect example of a rim leak
Dunk them in water, preferably soapy water.
Check valve stem, check the bead, look in the tread for small objects.
I have to do this shit ten times a day, you pick up a couple tricks.
>>17024336
>Aluminum Chrysler wheel leaking around the bead
Wow, something you don't see every day.
