Question re cam timing on NA 8

[michael]

Hi All,

Can anyone tell me, with certainty, the number of degrees before bottom dead centre when the exhaust valve opens, for a 96 NA8 standard engine.

Thank you
Michael

[broady]

no idea about before bottom DC but the spec is 10 degrees BTDC

[StanTheMan]

are you refering to spark or cam timing broady?
and yes they are related but would be two different things altogether.
what he's asking has more to do with the opening duration of the cam profile and where it starts to move the valve open.. .....right?

[broady]

sh*t, you're right. Nevermind me. Just re-read it.

The info you're looking for is here:

Mazda specs for the 95 model NA8 are:
IN: open 5 BTDC, close 48 ABDC
OUT: open 56 B BDC. close 14 ATDC

Thanks Magna_blue and fellas,

I was referring to the cam timing and when (degrees of rotation) the cam starts to open the exhaust valve and ideally when the exhaust valve then closes. That's what you have provided, right magna-blue ?

Regards
Michael

[broady]

Yeah, and the specs provided by manga-blue are exactly the same as the ones on the solomiata site...

Thanks broady,

Initially I missed the link in your earlier post.

Thanks for your help

Michael
