jevansio Posted February 24, 2008 Share Posted February 24, 2008 Leaping to Marks defence here , he's purely quoting what I told him on the day (which in turn was what I was told from Andy). Incase anyone is interested, the full details are on run number 1, the AFRs (at one point) showed to be in the 10's. I was OK with this as I had Ryan purposely map the car rich top end to keep things cool. For runs 2, 3, 4 etc Andy's wife wanted to sit in, so I jumped out. At the end Andy told me he was seeing AFRs in the 9's & it was this which was making me lose power (which was the basis for the comment I passed to Mark). I gave the car a damn good thrashing on the way home and it feels as quick as ever (AFRs in the 10's only at the highest RPM), so I don't believe the car currently has any fuelling issues. I will be taking it our later this week to log from the AEM to confirm. Quote Link to comment Share on other sites More sharing options...

Pixelfill Posted February 24, 2008 Share Posted February 24, 2008 the dyno was monitoring the exhaust, so I presume dyno. I thought gauges bottomed out at 10, at least my AEM does. Mike Quote Link to comment Share on other sites More sharing options...

I presume my AFR gauge, as it was what Andy told me after the last run when I went over to the car, unless like Mike says Andy was looking at a dyno screen & he was monitoring it????

Ryan.G Posted February 24, 2008 Share Posted February 24, 2008 Aem only reads to 10:1 The only way i can see it going this rich on the dyno is if the air temps went over 60c as i set the fuel to go rich then as a safety measure. When im next up in newcastle Jay were go over to Andy's place together and then see what happens Quote Link to comment Share on other sites More sharing options...

When im next up in newcastle Jay were go over to Andy's place together and then see what happens It was pretty cool (ambients of around 15deg IIRC), don't know what the intake temps were (I should have taken my laptop ) Maybe, as I say the car is stunning, if I wasn't happy with how it was performing I would have taken you up on the offer, but currently I love the car & don't believe getting another dyno result of 500/550/600/650bhp will change how I feel about it Quote Link to comment Share on other sites More sharing options...
