I'm running a ct s/c and was just wondering where my a/f ratio should be about when im wot with vtec engaged? I'm just trying to get a safe a/f until my tune date witch is in oct then I'll be swapping in the ems, But until then i daily drive the car with what i have now.


pre thanx for all responses

 

Aftercooled? how much boost you running?

Around 12.2, max 12.4 if aftercooled depending on how much boost you are running.

 

11.5-11.8

 

12s on a boosted motor... no.

In the 11 range.

 

Its just 5 psi for now cant wait going 10 in oct so 11.5 a/f would be good?

 

11.5:1 is perfect for a fi setup.

rich-best hp/tq is around 11.1:1. for higher boost levels, etc.
lean-best hp/tq is around 12.1. for lower boost levels, etc.

 

Ok awesome thank you

 

Load of rubbish, this is fine for low boosted motors which the o/p has. A supercharger esp aftercooled runs alot colder than a turbo. If it was a turbo/high boost sc I'd agree.

 

Yeah, cause his original post says how much boost he's running. As you can see that's what I replied to... All it says is he's on an UNTUNED CT supercharger.

Are you speaking from experience i.e. what you see on your gauge? You have better gas than we do, that may be why you think it's cool to run a 12 and up. Here in the states we have crap gas... 11 is where it should be.

thanks anyways.

 

at least you are not paying ~1.8 Euro per litre (US 93RON, EU 100)...

PS 1 Euro = 1.27 USD, hence with todays exchange rate you are looking at 2.286USD per litre. 1 US gal. = 3.785 litres
= 8.65USD per gallon!
