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...

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.

no, the inlet (dephaser) pulley shifts the timing there isn't two lobes for each valve like in one of the videos above.

Re: Mk1 172 Hybrid Track Car Project heh, they are not good in weather like we have had the past week or two, unbelieveable how hot it gets inside. Sliders are useless and dont let in any air at all really, and love to leak when it rains, oh well! Got some more weight to loose yet, but it will...

Re: Mk1 172 Hybrid Track Car Project Think its around 800kg, keep meaning to go and get it weighed, but things keep coming up! I go past the fire station alot, suprised I havent seen your car around before, nice and low. Fiesta, nice....what Mk/Spec? :)

Re: Mk1 172 Hybrid Track Car Project Lowton, near the Co-Op if you know where that is... I only carried on past the leigh bypass because I thought that Black Clio was going to try it on again, but he turned off down the bypass.. Usually has two seats in, took the other out for the french car...

Re: Mk1 172 Hybrid Track Car Project ahhhh that was you then! I was thinking, where can I look for this guy, first person thats given me the thumbs up/wave! My mates into the vag stuff, was going to ask him what forums people use... Seems you found me first!

Had a 3/4 height front plate, 05 reg maybe? Had dashes inbetween in the 3 parts of the reg...black/anthercite front diamond? you were behind me after that tw*t in the BMW decided to be a hero, upto the leigh bypass :cool:

hes gone picking it up at the moment, left about an hour ago

you want freds timing tools to check the timing? didnt give them him back incase you did...

Re: Mk1 172 Hybrid Track Car Project haha, yeah was good to have a chat!

As mentioned earlier also, it *could* be the timing...Dont know if you remember Burps 172 ph1, used to run fine, just felt a bit underpowered.... He had it rolling roaded at 140odd, then checked the timing and it was out. It can be a certain slight amount out before it starts getting...

there is no 'larger' cam...its nothing like vtec. vvt = variable valve timing, it changes the position of the inlet pulley at a certain rpm (1200-1300) to aid low rpm driving. the 5k kick is purely the design/components of the engine, hence why it sometimes disappears with a map/and or...

vvt is at 1200-1300rpm on 1*2s, its for low down drivability. lol. edit. beat to it doh.

yeah....was gona send off booking form thingo for hamilton fields, seems the cheapest tbh. fair enough lol

so thats why you were opening and closing the flap then kneel, lol.

he wouldnt move over as we were getting upto 120ish jellybeans on the runway detour we took......when he finally did I went past to the end of the clock......slowed, and he went past again, then the same again....after that he stayed behind...lol.
