If I am not mistaken that title belongs to "Monster" who is known to post on Roadfly on occasion. The fastest XKR would have to be the world famous Norman's car, though fitted with the early Kenne Twin screw setup & intake design, he has been known to claim up to 650hp. However this is more than likely more urban myth than fact.

Not sure where my car would be in ranking, but think it is pretty quick ;-).
When it comes to the x308 XJR, http://www.matmoranmotorsports.com/ also has done some mods.

That's very impressive - it would put the engine output at over 470bhp, meaning the work done is worth 100+ over stock.
I'd love to see under the bonnet, also information on the cam's and injectors you're fitting.
If this is correct, it would rival TVS supercharger performance, great work. Just thought, what are your intake temps, have you any idea? Also, VIDEO of the pulls!!!

Cloudy little kitten sorry I mean Thundercat, I have a car coming to our shop in a few weeks to have one of Andre's Twin screw setups installed as well as the heads ported. I should have Monsters car in for this as well as a few more tweaks. Please feel free to come down & have a look as it is not that far from you. As a side note I know he has also changed his rear end ratio as well as custom free flow exhaust system.

assuming that's 370rwhp on a rolling road?
not a bad increase over stock, which mine is, and pulled 320 on a hub dyno. i've heard stories that increasing the pulley size doesn't net much more hp due to the extra heat, but does increase the area under the curve significantly, which would mean the difference is much more noticable on the 'bum dyno' rather than on paper :P

Not sure what the conditions where on the dyno, hope to see that also on the dyno slip, but if 370 rwhp (445 bhp with 17% drivetrain loss) was measured with normal fuel (i.e. no race fuel or additives which I assume, but am not sure due more than likely high boost pressure), it is not bad at all, although more changes where done than just a pulley one… The drawback is of course the heat soak, and there more work is needed if you want the power for longer runs that just a short one on the dyno. Already gave some suggestions in another thread.
