who knows what "rpm" means ? .... not THIS guy ....

yuo kept coming back, you knew better after the first time … what u want me to do about it ? :gotme:

Make a good post so we can be happy again. :slight_smile:

fine, ill go upload some porn for you guys …

hotrodkid I applied the powder to the chick’s ass in your avatar, BTW. :kiss:

what toyota are you working on that makes one cam spin faster than the other?

i think u ment to say “when one cam begins to advance or retard”

"even the old cable driven tachs are measuring camshaft rpm.

  1. have any of even seen a cable driven rpm guage? ive only seen one on a chrysler big block, it was a high performance option.

all the ones i’ve seen are a part of the distributor.

the distributor spins at CAMSHAFT rpm, which is 1/2 of crankshaft rpm. (distributors are not driven by the crank. they are driven by the cam, and turn at camshaft speed) all four cycle engines turn the cams at 1/2 crankshaft rpm. i’m not aware of ANY four cycle engine that takes a reading of crank rpm for the tach signal, unless it’s a newer engine using the crank sensor for the signal, however, this signal will still be “conditioned” to read 1/2 of crank rpm. so when you look at your tach and you see a reading, say 5000 rpms, that’s CAMSHAFT speed, not crank speed. tachs do not convert the signal they get into a “1/2” speed signal for rpm. they read the pulses sent to them and display them as rpm. crank speed will be TWICE what your tach says…two cycle engines, or two-strokes are a different beast, and those engines will read crankshaft rpm, due to most of them not having cams. (old detroit diesels are the exception here, they are two strokes that have cams, but they only actuate exhaust valves. those cams are driven at crank speed, and the tach signal for those is either mechanical via a cable, or electronically via a cam position sensor). one thing to remember here is it takes TWO complete turns of the crankshaft to complete ONE cycle of operation, and only ONE TURN of the camshaft. camshaft speed is what we measure as rpm. "
2. most of what hes saying it true except when he said somthing about 5000 rpm. IM GUESSING YOU GOT EVERYONE CLUELESS BY NOT READING THIS MANS WHOLE ENTIRE POST. do u have the link? this guy is talking about setting up a aftermarket cable type tachometer.

one cam spinning faster than the other huh? variable valve timing is just what is says, variable valve TIMING. it has nothing to do with speed, all it does is change the timing a few degrees. how are you going to create a speed delta between two cams that are running off the same chain? you should probably study up on VVT-I a little more if youre going to school for it.

Yeah, i’m sorry for not typing perfectly what I was trying to explain but i’m glad that DJ nick understood what I was trying to say because I meant when it advances and retards the timing but I guess i didn’t think about it enough when I was typing it. i’ve taken apart the systems and actually seen how they work but I guess I’m just a retard and really didn’t think about it before because now i realize what I wrote didn’t make any sense. :banghead: I even said Toyotas vary their intake and not their exhaust and I didn’t even think about it until you pointed that out. I guess the way I typed everything up was no better than the guy who originally was quoted in this thread. Oh well i’m retarded but i’m ok with it.

god may measure yours, but God definately measures my Mustang

The spiritual chi within my Honda is in perfect harmony with my aura.

now i have a headache

god damn it u guys know wayyyyyyy too much about engines!!!

“ill take engine technicial for $400”…

—“This person knows all about combustion engines”

Who is Mr. Smith?

No im sorry that is incorrect…

the correct awnser is. who is my local mitsubishi motor mechanic.

lol

^ correct, because they have been in the engines themselves more than anybody else. lol
