how many rpm should my starter be turning the engine over at? its a s5 tii

 

my haltech is reading somewhere between 120 and 200rpm. is this normal. im having some starting issues on a fresh rebuild and im checking all my bases

 

when you click the ignition to on the needle should move, then when it cranks it will bounce anywhere between 0 and 300rpm. If all is good it'll start.

Check the wiring on the starter and the Crank sensor as well as the battery terminals.

 

About 230rpm observed on a Palm connected to a Zeitronix. http://www.pocketlogger.com/index.php?pid=plzt

That's from memory. I'll look later today and if I'm off in the figure above, I'll post the other figure.

That's a difficult question you asked. I mean, what are YOU observing for the rpm and what are you using? Don't use the tach because that is not an accurate method in my opinion. Maybe a digital meter set of freq and the fuel cut so the thing won't start, would be a worthwhile method.

 

Nah. With the fuel pump disabled its more in the 215-220 rpm range when constantly cranking. Closer to the 220rpms. Series four turbo.

Someday I'll check the non turbo car. I remeber the 230rpm figure from somewhere.

 

I think the FSM says it should be between 200-250rpm

 

Im reading the rpm from my haltech via my laptop. im getting 120-200rpm
