Healthy hot start time?
Im one for knowing and noticing any sounds or feelings that my vehicles produce, i know hot starting issues generally relate to low compression on these engines, but what do you consider a poor hot starting time?
Ive noticed over the past couples of weeks on occasion that my car is taking slightly longer to turn over when warm, nothing drastic but the norm would be about two chirps of the starter motor so almost instant, however this has seemed to increase on occasion to four chirps of the starter before firing (3/4 seconds?) is this potentially an indication of my car becoming less healthy. i mean how did you guys first realise when your car was losing compression?
My next step will be a seafoam clean as compression testing for rotaries is even less common in the uk than in the states, but if needed i know of a place around 80 miles away.
Vehicle info
Miles; 45,000.
Coils, plugs and leads changed at 32,000 miles.
2004 model with all recalls as far as the mazda dealer tells me.

on a 100% healthy car the difference between a hot start and cold start is basically nothing, it should start the same either way.
however i'd say 2-4 rotations/chirps is totally within normal. so if it takes 4 sometimes, it takes 4 sometimes. if it takes 2, it takes 2

should have stated, the battery was replaced in January so pretty damn new. alernator and starter are '?' not been changed as far as im aware although if the starter was a crappy one would it not have died out already. im kinda waiting for this elongated start to happen when i start it cold then il be a little more at ease.

Pre 2006 models came out with a weak starter. You should check on that (if you still have the original starter) as the upgraded starter spins faster and does make a difference.

check this video out (not mine)
Compare the cranking speed you hear in the video to your cranking speed. then you will know if your starter sounds up to spec
slow cranking out of spec starters im pretty sure will always take longer to start a warm engine, even on a healthy engine

Im just curious as to why all of a sudden say every 1 in 10 starts will take just that little bit longer. i have meticulously maintained this car, im running no cat as that can contribute to engine failure.

Thanks for the vid, the upgraded starter in this video does sound substantially faster than mine, mine cranks similar if not the same as the old starter + optimax battery.

Could be many different things but I wouldn't worry about it so much but
here are a few things you can do for free which might help you
-Clean your ESS
-Clean your MAF
those are easy to clean and there are a lot of writeups on it
if you have not changed your coils, plugs and wires in a while then its probably a good idea to change them all at once, i purchased my plugs and wires from rockauto.com for $80, then I purchased 4 SMP coils from ebay for $99, definetly worth changing those and not worrying about ignition for at least another 10,000 miles.

Must give this ESS clean a go, is it actually worth it?

yep, its easy to clean, and the worst case is that you don't notice a difference. i did mine from the top, but i believe i had the airbox out, otherwise its easy to get from the bottom, its 1 10mm bolt.
you should also reset the NVRAM, with the 20 brake pedal stomp method.

that hole thats revealing the flywheel is where the starter goes correct. where in relation to that should i be looking?
