I dont think capa would have brought a product out in the market without knowing it would be up to scratch

We ars discussing the air/fuel mixtures here not the actual product, obviously the mixtures can be made richer or the boost lowered to make the mixtures safe. 

Peter

This little black duck has heard that the AF ratio's are infact mid 14's and in a few load points nearly 15.......

I hope you are joking, right? 

The full load air/fuel ratio should not be leaner than around 12:1 in the high rpm, any leaner air/fuel ratio is starting to approach the red zone. 

Peter

I saw A unichiped subi on the dyno last week with 12.5:1 at full peg on a power run.

Not tuned by APS you won't though air/fuel mixture is up to each individual tuner.

Thanks

So Peter is 12.5 what you would consider to be dangerously lean ?

On a turbochrged engine I alwyas prefer to maintain at lesat 12:1 air/fuel ratio at high rpm full load conditions, this air/fuel ratio may vary a little depending on the brand of engine though fatter mixtures are always safer and keeps the EGT down lower/safer.

Ok. This is all new to me and I am wanting to learn more, so to help me put it into perspective can someone answer this for me.

11.0:1

11.5:1

12.0:1

12.5:1

13.0:1

13.5:1

Out of all those above which end is to lean and which end is to rich, since pete has already stated the 12:1 is what he likes to call optimal, I would like to know the rest. Thanks.

13.5 IS lean

[turb06]

Thanks for the injector info Dazza. What valve springs are best to use?

<{POST_SNAPBACK}>

std till you have a problem same with the injectors

this is at best your answer to injector size!!!!!

enjoy dw

But it might be a little too late to change valve springs after you encounter a problem, and for people like myself and Gav that cant change them ourselves and have to fork out both parts and labour costs that's not really an option we want to take, so my advice Gav is to play it safe, but that means for me getting valve springs done ASAP after a ecu change or edit, and I will take the advice of the others who have there T's already at the power levels I want.

Any more info on valve springs you need pm GOLDIE he is the resident expert on those.

I went in a rice mobil (180sx) running about 25 PSI and about 580rwkw (far from stock obviously) that was the best car I have ever been in. I was still wetting myself 5 days later lol.

777.8 hp at the rear wheels is a bucket load for an sr20. How much had he spent on the engine to get that?

bring it to auto salon he will be a legend as that's aprox 200rwkw more than the record!!!!

or was it 280rwkw?
