I would be grateful if someone could tell me how many pistons an 1985 RX-7 has.

 

I sure hope you are joking with 650 posts you have on a RX-7 forum???

For ur info (if you are actually ignorant enough) first gen has a Rotary Engine. It has two rotors. No pistons

 

actually i believe the brake calipers have 2 pistons..........but other than that




*cough* POSTWHORE *cough*

 

One at each corner,....!?

 

7... clutch slave, clutch master, brake master and calipers.

 

Good one Paul!

 

inittab-trivia night question!

revhed- thanks we are getting there

 

okay ... i'll bite, too

9 ... if you add the hatch struts

how's that?

 

If the hatch struts count, then I can think of 17. Ones mentioned above, front struts, rear shocks, and the 2 front & 2 rear bumper stocks.

 

what about the oil metering pump , that has a piston

 

dashpot has a little piston in it

 

How about we change the question to how many cylinders does and Rx-7 have? That way we can add door locks, and other misc. junk. Doesn't the OMP have a small pin sized piston too. Jeez, we're going to be at 36 in no time.

 

define piston please..... ok, what is its origin? hrmmmmmmm
P I S T O N, piston

 

SAME AS THE NUMBER OF VALVES IT HAS

 

so not true, your tires have valves, but no pistons, unless you count the valve core plunger. some game this is, hey everyone think of ever single itty bitty part on a 1st gen and figure out how many pistons there are

 

Are there pistons in the locks?????

 

Actually, the RX-7 has dual/split braking system... The master cylinder is a single cylinder, but two pistons...

Two hydraulic systems, one for front-left and right-rear; One for the front-right; left-rear brakes... In the event of a hydraulic failure, you still have some braking ability.

 

really? hmmm, seems dear old dad was right afterall....

 

eh?

I have diagrams from my text book from "Basic Braking systems"... A course I took while working for a shop.

Hey... Get paid to sit around and discuss brakes... I'll do it!

 

The stock fuel pump has an electromagnetically operated piston in it.
The float bowl solenoid is essentially a piston that closes off the vent when the car is shut off.

 

My dad and I had a discussion about the brakes a long time ago and it ended up with both of us getting annoyed and not really solving anything, if what you say is right then he was correct.

 

ROFLMAO! Great trivia, man. But it's about the RX-7....is that really trivial?.....

 

For those of you that still have AC, you need to add the pistons in the compressor.

 

Deceleration valve, Roll over check valve, coolant valve on the heater core, air ducting valves in the HVAC system, air control valve, thermostat.

Am I missing any??

ah crap guys, think about it, most solenoids act as pistons.

just think about the rat's nest.

S, GS, GSL, or GSL-SE?

5 speed? Automatic?

You could count the pistons inside the valve body of the automatic transmission...
