Me too plums, see pic, fuelabs - centre - bottom, Mine runs 53PSI at idle, vacuum port plugged, and about 78PSI at full noise - ( 2x new Denso fuel pumps) It ran lean on the dyno, raising fuel pressure was something I was going to try.
Another thing was to fit a pair of oxy sensor manipulators, same as I have on my Ducati PERFORMANCE BOULEVARD - O2 Manipulator |

Please explain how the oxygen sensor manipulators will help if the problem is that the injectors / pumps won't supply enough fuel? |

I have an aftermarket MAF, which has a mind of its own. If indeed the problem is that the pumps or injectors physically can not supply enough fuel - no amount of oxygen sensor manipulators or electronic trickery will alter the problem. The idea of the manipulators was to fool the ECU into thinking it is lean, which in fact it is through all rev ranges, and get it to supply more fuel. There is an old dyno here on a post, showing around 13.8-1 @3500RPM improving to about 13-1 @ 6,000RPM. I don't think I've suggested that it runs out of fuel, |
My xkr just did this 2000 model after adding upper pulley and porting,jaguar told me,I need a 5.0 model car, screw them.

Any chance you could repost what you are trying to say in more common english?

Spare Tire
BTW, XJR99, I have a near-perfect spare 17x7.5" rim to match those shown in your trunk, with Pirelli P6000 tire, so it will work on XJR 18", OR, with OEM tire on XK8, I think is the other application for these rims. Think it has been on ground once, but not for long, as both tire and rim are as near-new.
EHT/Aiken, SC |
The rims are 7x16 and DR tires 255/50/16
|
Let me remove from trunk and take some photos. (Soon as this storm passes!) I tried to rely on my memory. Bad idea. Besides, inside of rim still sports its white BAR code sticker!!
