Afternoon, all! Been a while since I've been on here, but in the meantime I've managed to get my Ex-Plod X30XE installation into my Reliant Scimitar almost finished and has been road legal since August (just some niggles to sort out).
I know there's a lot of folklore around regarding ex-Police cars and whether or not they really were standard but after a quick run on the rollers (just after I'd got it on the road - wanted to check the fuel pump was up to scratch, honest
) I have a question regarding what looks to be rich running. At WOT (as befits a dyno run), the mixture just gets richer and richer - worryingly so.
Second plot shows torque and AFR - I think the hiccup is a sticky ram valve..
Exhausts are a pair of Calibra 3-1 manifolds to 2" downpipes and into twin 1.75" systems (no cats) - first box being an offset silencer, 2nd box on each side straight through.; air filtration is by an eBay cheap K&N cone copy if they have any bearing on matters (although if a restriction, I'd expect the torque/bhp to tail off rather than be a gradual richening?
Comments welcome..
