Saxo, what are you doing with the engine first, because if it's just cams and remap and not TB's or some form of forced induction, then 280 duration is just far too high. 265 should be about the limit imo, 270+ has never performed well on the F7R engine due to the power coming in as you change gear... or worse, not at all lol. If your building some sort of forged bottom end you'll be okay I'd imagine, but for standard road use around 260 you should be looking at and they are fine for OE lifters.

Was only thinking about them, would do induction/exhuast first. I ran catcams 708's (about 270degree)in my vts with full exhaust and induction and it ran ok(slightly rough) on the standard ecu when they were just fitted.

Was only wondering if you needed solid lifter and up rated springs for 280's.

Not modding the willy now, getting new project.

Can any one tell me if i'm right here, I'm just quoteing a conversation I had just today.

F7R - Williams 262 deg. (true) duration Inlet 9.2mm lift

looks about right mate from wot i remember from measuring....actual figures are in my workshop.

1.8 16v are somehwere in the middle.

Williams cam durations are 256 and valver even lower iirc... they used 260+ on the F4 series

[stew]

i that sounds rite jesus.

no way a std willy cam duration is 262deg, as there would be sod all point buying aftermarket 265deg ones then!

[stan]

hmmm i was just looking at lift values!
