Thats what I thought Nick, was just confused as Paul said he thought it was the slowest Clio ever before we took it on!
Anyway, Comps look ok, up around 200psi, pretty much even so no valve damage.
Timing wise...
Now one thing we do know is Zetecs, and when fitting Kent cams to them, the factory settings are no good as when they are ground, they are not lined up anyway, hence we usually use a DTI and set valve lift ATDC/BTDC in mm. Thats for Kents on a Zetec. Clios *may* just be a simple fitment of uprated cams fitting to the standard OEM locking points, however, judging from todays results, maybe not. Danny would know more about this, any ideas Dan?
Torque is as always lovely and smooth, although only around 130lbs/ft.
I will try advancing the ignition timing up, but as I said, VVT on, or off, there is no change to the graph (and certainly no change in the AFR which would indicate the VE is not changine, hence, the cam is not moving. Thats my logical mapping deduction that I would apply to any other engine/mapping task.
The idle is alot smoother now. Perhaps when the VVt kicks in we will see 190+bhp. Remember we have only altered cam timing and lost power.
Ah... thought whilst writing...
The cams were advanced, lets say 12*, and the VVT has never worked (dud unit perhaps) hence we were making good 'VVT'-ish powerm, but not quite the fuill 16* hence full 200bhp.
The idle was choppy before, now we have reverted cams to standard, we are making VVT-less power (The Zetec ST170 makes around 130bhp with no VVT, and 195 with VVT on TBs, so we have seen it before, VVT can make big differences) but the idle is lovely, hence VVT may of never worked at all (dud unit) and with the cams now set correctly and no VVT we are not seeing the resultsd we should, we are seeing a perfect 'economy' map with a retarded cam....
