Current events discussion

Because I wasn't talking about a 77 originally. You must have been.
I was. But for some odd reason you decided to call me a liar, and claim no such thing exists.
When you didn't even know what I was referencing.
I'll hand it to you, that was odd behavior.
The Turbo cars had like 6psi of boost stock. I removed the regulator on the intake and plugged it. I added the blow off valve and was able to run just over 12psi without any issues. This made the car much more fun to drive. An extra 6psi of boost yielding 5hp conservatively at sea level so call it an extra 30-40hp on top of the stock 180hp. The T-5 shifted just fine. Yes, the Turbo 280zx's came with T-5 transmissions.
Were you just experimenting to see what you could do, or did someone tell you to do it?
Did you find out the hard way that it doesn't work well, or did the car get eaten by rust before you found out?
AFM? No, these were speed density cars that relied on a carbon track and pick up needle for the signal.
Datsun/Nissan called them Air Flow Meters.
Looked like this, right?

Yes, a speed density air flow meter. But while you had to have people work on your cars because you have no skills, I get balls deep and do that work. Below is me adjusting/fixing the afm so that it ran much more smoothly.

Like I said in the beginning, and you then you thought you corrected me: An air flow meter.

That's cute.
"Balls deep", but never did anyhting that required a lift.
Yeah, you were quite the wrencher!

So when did you learn that eliminating the boost restriction and adding a blowoff valve was the wrong thing to do? When the engine grenaded from too much boost, or when it ran rich as stink whenb you let off the gas?

Why didn't you just do an EVC or even a manual boost controller?

He just stand the thought that somebody might be smarter than him.
When I say "air flow meter" ands someone "corrects" me but is wwong with their "correction", I have to assume they know less than me about the subject.

It doesn't help that he added words that NO wrench would use, because he saw them on some pictures he found on the web.
"carbon track and pickup needle"? GMAFB. That's like a carpenter saying "I picked up some 1.5 inch by 3.5 inch by 96 inch untreated pine to hang some gypsum board in my house".

Type matters especially when you referenced limp mode which these cars didn't have. So I clarified for you. However, now you want to try your gotcha crap when if you had any automotive knowledge of your own you would know there is no limp mode for the 280zx cars.

Yes because I had access to jacks, ramps and a pit.

I still am.

Being that I know what the stroke of the F54 block is and compression ratio the turbo P90 head yields on that block and the fact that I set the timing on that engine, I was more than sure I could run 14psi of boost if I wanted to.

That IS a manual boost controller.

STFU, you don't think that is a carbon track? Would you like to see the service manual for that car? I hope you know they reference the CARBON TRACK in the SPEED DENSITY air flow meter.

Take out the AIR FLOW METER and the car will run, albeit poorly, buy enoguht to "limp home" if home is nearby and you can drive slowly without gwetting killed.
Yes because I had access to jacks, ramps and a pit.
So being in a pit under thwe car means "never had to be on a lift"?
That's pretty damn funny.

Was that the year that had the timing marks that were damn near impossible to spot, unless you put some yellow grease pencil or some WhiteOut on them?

If you know so much, why did you think a blowoff valve mattered when you eliminated your boost control?
Or did you learn about the block and head affter you wasted an engine?
That IS a manual boot controller.
Oh? Interesting.

A blow off valve has nothing to do with regulating boost under acceleration.
Care to try again?

No wrench would ever call it a "carbon track", unless they were reading something in a book out loud, or got an AI result on the web and are repeating it.

No wrench would think a blowoff valve controls their boost under acceleration.

By the way, WTF is a "speed density car"?
Are we falling back to that discussion where you said the speed of sound can be faster (or slower?) than the speed of sound? Something about how subsonic sound moves slower than the speed of sound?
That was pretty funny stuff.

Not a "mode" of the car.

I had access to a pit. I never said I had to use it for the zx.

When you know what you are doing you don't have to search.

Can you see the tabs *****? Can ya?

The factory piece limits the boost to guess what 6psi. I put a boost controller on there so I could increase the boost. Pretty common knowledge.

It is a manual (meaning controlled by the user) boost controller. Set it to a specific psi, MANUALLY. I never said anything about acceleration.

Actually, it is a Mass Air Flow meter. Speed density was my 4cyl Mustang.
