Lack of a 5k kick. Normal?

Tbh its just witchcraft and there is no impressive mechanics going on. Pure hocus pocus y0

Thats the magic of the vtec y0

Stop taking the MIVEC.

 

[Russ_16v]

:S

Stop taking the MIVEC.

Now your getting serious

Mitsi FTW

just hit Ecotec y0?

Rover K Series.

HG just kicked in, yo.

Oh why did I bother asking a serious question lol.

lol sorry dude, i wouldn't see it as a problem at all, if it goes well then thats all that matters, to be honest the std Renault maps iv seen can be like night and day, so it simply might be a 'good un'

Cant see that as im at work mate, but if you mean the VVC, it simply put the inlet cam is adjustable to move the timing to give better low rev running and emissions, and re-adjusts , which in the 'old days' you had to have it either one or the other

if that makes sense lol

 

[Jonny1*2]

i mean how are the cams adjusted on the RS engine? does the rocker lock on them?

 

[f0xy]

no, the inlet (dephaser) pulley shifts the timing

there isn't two lobes for each valve like in one of the videos above.

 

[Jonny1*2]

thanks foxy. will have to do a bit more looking. can't visualise how it works. Does it just slow down the inlet cam?

 

[f0xy]

the first part of the video you posted explains it perfectly, the inlet pulley changes its own position on the inlet camshaft by a set amount of degrees.

This is done by the solenoid on the top left/cambelt end of the rocker cover. Its oil/hydraulic powered.

 

[Jonny1*2]

ah right, so as the pressure increases, inside the pully moves further down the cog type end of the inlet camshaft reducing the rotation speed and hense increasing inlet. If that makes sense. Sort of like gearing in a way

 

[f0xy]

sort of. not *exactly* like the illustration, but..

the center part of the dephaser pulley is solidly bolted to the end of the camshaft. the 'outer' part of the dephaser pulley can move (the part with the teeth for the cambelt).

This moves when oil pressure to the pulley increases, which happens when the solenoid (on top of the rocker cover) is activated.

 

[Jonny1*2]

ah right. thanks for clearing that up mate.
