Marketing speak.

Enjoy new episodes


Also, enjoy access to our existing original programming library, which includes ded

I don’t understand why they batch fired the multipoint EFI which results in atomized fuel pooling behind the intake valves and dribbling into the combustion chamber instead of sequentially firing them so atomized fuel is entering the combustion chamber for each cylinder when the intake valve is open.

Big fucking fail in that episode in my book.

It reminds me of when I worked in the magazine industry and we were to the point that we were writing tech articles that we had done a year or two ago.

Most MPFI setups are batch. Even the venerable 22re. They talked about that being the most common model in the episode.

But I agree it makes the comparison less clear

I did enjoy the few comments that Dave and Fred made about DED on the UA coverage. Kind of surprised it didn’t land on the cutting room floor
 
With how capable the aftermarket EFI stuff is otherwise, I'm kinda surprised batch fire would be the more common way to run them. OEMs figured out sequential injection in the 90's.

The main benefit to sequential is idle quality. Past a certain rpm, from my understanding, there is no real benefit to sequential as the injectors are open longer than the valve anyways. (No, I haven't done the math, but this information is widely available so I'm regurgitating it)

Individual cylinder fuel trim of course is only possible with sequential but I don't think that's used outside of motorsport.

Pretty much all of the non-tbi style aftermarket efi is sequential capable. Only the lower end stuff isn't. It does take more hardware to use which means more money for no real benefit for most people.

Without getting too far into the weeds, from a performance standpoint as rpm increases you don’t give up much batch vs sequential. The events are happening so fast that it starts becoming nearly a wash.

Edit: dammit beat to it by a second ^
 
The vacuum leak episode was interesting, surprised to see how much they gained. Can see why restricted class racers would try and get away with that kind of thing.

Even with sequential injection OEMs would fire the injectors onto closed valves for many years until emissions got so stringent they stopped. The cooling effect was worth enough to them to make them do it.

Of course this is also something you'd never see making a couple dyno pulls...
 
Jesus…

Never watched Car Fix.

Gave it a shot.

Tell me you don’t know how transformers work without actually telling me you don’t know how transformers work.

I'd bet 99% of the people in the world have zero idea how a transformer works.

There's just so much that's fucked up in that video. The episode makes that dude look like a clown.

I like the part where he takes the screwdriver (with magnetized tip) and says "it's becoming magnetized" and the "magnetization is what's stepping up the voltage".

You would think that if you're putting yourself on national TV you'd make sure you knew WTF you were talking about before you got in front of the camera and starting babbling.

I think the show was better with Lou and Jared(?). I like Jeremy, though. He was good on the power nation shows years ago.

I can’t figure out how Truck U is still around. I’ve tried to watch it, but it’s 2 minutes of content and 21 minutes of horrible commercials.

Half the shit they have on is unwatchable unless you're into infomercials.

I mean " All Twats Garage" you can't be serious.:barf:

The EFI thing was funny, because Ford did sequential electronic multiport fuel injection back in 1986, but those Chevy guys don't want to talk about it.

Only the 5.0l HO though. Everything else stayed batch. My 95 is still batch, and I kept it batch even though it has a ms3x in it now that can do sequential.

Tons of stuff went SEFI over the years. I think all 3.0s, at some point the 2.3 converted. The 300 got it in '96. I'm pretty sure the 5.0 got SEFI around then too.

Not too long ago I saw comments on Youtube or something from some idiot saying he was tired of all the Fords and Mopars and wanted more SBC content. All I could think was

ETA: I also remember a bunch of times David has mentioned that his nickname on social media is unofficially 'David Fordburger' because the chevy babies get so mad when the spotlight is off of GM products for more than 3 seconds.

I suppose I forgot the mention "until the early to mid 90s". The trucks eventually got the HO sefi treatment on the 302s, I don't know about the 351. I know the lightnings were batch still. The 460 stayed batch through... A long, long time, except for the obd2 ca models.

And I was meaning v8s... Cuz I don't really know nor care about any of the other ones.

That's hilarious. They have how many Ford project vehicles? Is the ford muscle truck still around?

I don't really mind, when they do a Ford, they look like jackasses anyways.
