Boost And The Stealth

[Lawsy]

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.

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.

remember though they were ritcher than std map by about 20-30% so it was a step in the right direction and a lot ritcher than some others ive tested!

Nick I'm not sure what you are referring to though the stock XR6T engine runs very rich mixtures at stock boost levels.

Peter

that's what I mean from my coment that I'd like to do another as an indipendant test cause I've never seen one that lean as std.

but admittedly have seen five moded t's leaner three mentioned earlier and two since obviously you dont tune that lean but someone's dealers might have?

peter I see it all the time it is a joke on the consumer im with you wayway to lean although my red flags are set slightly difeerent to yours!!!

I have the Edit, and this is the best thing I have ever bought. 8 PSI is a huge increase in Power (I don't know about 300kW at the motor, but it would have to be close to 280? The 10 PSI would easily be 300kW).

I have a boost gauge in the car, and yes stock peaks at 6 PSI, but is mainly 5 PSI (This is also backed up by a stock Dyno graph I have)

Hope this helps

Do you see 8 regularly? How is traction in 1st and second?

<{POST_SNAPBACK}>

8 PSI comes up as quick as it can, and stays there until you back off. Traction is ok in 1st and 2nd. If you want to break traction it is pretty easy though. It's not something I'd recommend when going 80kph

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

In a simplistic form, 10psi does not necessarily mean 300rwkw, From my understanding, and I will be happy to be corrected by Peter or Nick, it comes down to the tuner and the car. There are members running 280rwkw with 10psi and others running 330rwkw with 13 psi. I am running 10.5psi with 260rwkw, which will sometimes rise dependant on air temp. I have had 11 psi @ 274rwkw. so the boost alone will not dictate your rwkw., it's obviously a combination of the total tune, and as mentioned it comes down to your tuner.

BTW I would not want to be running 10psi or 300kw with standard injectors. I would suggest air onthe side of precautionery and upgrade injectors and possibly fuel pump if you want to consistantly run those sort of power levels.

lol

waiting waiting

you know I been lurking around the thread off ff and ls1.com.au and you know there are a lot of good reading in the archives with peter as the main actor always fighting with everyone ...but it is a good read ...or laugh should I say

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

Thanks
