Just finished a discussion with the local Alpine Renault guru after he has given my S2 the once over.
Recently purchased, I haven't been completely happy with the engine performance (although it isn't slow).
Nothing low down and bad mannered, which I had put down to having a giant cam and 45mm Webers.
As the detailed knowledge of the engine build and spec was light on I though running it past 'the man' was a reasonable idea.
Summary, found the ignition timing was fairly retarded compared to what he thought it could tolerate and basically not much else.
Advanced the ignition and (he tells me) it is a lot more responsive everywhere.
Before I disclose what the timing is, anyone got comments about what they think a warm R16 crossflow should run as static and maybe maximum advance?
Fuel is 98octane RON.
I know this is a 'how long is a piece of string' question but have to start somewhere.
Other question is in regard to recommended oil, this motor is still fairly tight, think I will drop the oil shortly and replace with some straight mineral oil, maybe 20W60 (no cold weather here).
Might swap to a synthetic later but given it is an old design suspect it will need to remain a bit heavier to keep up the pressure.
