Re: Mk1 Hybrid Project

Awesome project, I feel sorry for you! Amount of times you have rebuilt that engine! Out of interest how much wider is the 172 track compared to the williams?
 
Re: Mk1 Hybrid Project

Its the same width, the wishbones are the same as williams wishbones. The difference is the castor of the hubs/wheels, 172 Castor is different to williams, the holes for the bottom ball joints are in slightly different positions IIRC
 
Re: Mk1 Hybrid Project

I just wanted 172 brakes basically, lol, and I suppose more 4pot options if it ever goes that far (Larger disks mainly, 280mm over 259mm)...

But at the same time I wanted to be different from the normal widetrack, IIRC only one other person has done the full 172 running gear/suspension wise
 
  wait and see ;)
Re: Mk1 Hybrid Project

has your mum seen the bricks yet ;), oh and M3 man gave me a funny look before so i told him f**k off at traffic lights lol:)
 
Re: Mk1 Hybrid Project

Went on a bit of a drive today, did around 50 miles, then it started spluttering a bit, like it was running out of fuel, but I knew it was not empty...

The engine sounds like its staying at the same RPM but the needle goes mad and there is like no power until the needle picks back up again...

It cut out after the 2nd video and would not restart, I pushed it off the main road, 10 mins later eventually got it going by turning it over with the pedal to the floor, then drove it a mile home (luckily I was nearly home) and it only did its spluttering thing once...

Re: Mk1 Hybrid Project

Bad earth or an earth fault somewhere IMO, how is the rev counter wired on the Mk1's, through the coilpack?

Re: Mk1 Hybrid Project

If the rev counter is wired through the coilpack, thats what I'd change.

Re: Mk1 Hybrid Project

rev countered is wired straight to the coilpack, hence my thinking that the coilpack either isnt getting a signal (CPS) or it's not functioning properly...

afaik, all mk1 coilpacks are the same, so see if you can borrow one from somewhere

nice easy fix if it is! :D

Re: Mk1 Hybrid Project

does this problem get worse/better depending on engine temp?? i'd say coil too if so

Awesome mate, glad it all worked out! Get some video's :p
 
Re: Mk1 Hybrid Project

not sure, id just gone a pretty fast hard drive for 30 mins then it started

then when it cut out near home, i pushed it round the corner, and 10 mins later it fired up
 
Re: Mk1 Hybrid Project

Seemed to run fine this morning, so I was stupid enough to drive to warrington, lol

Decided to cut out like yesterday on my way home, and would not restart at all. RAC came out, again, lol.....got home eventually.

The guy seemed to think its down to a bad earth, as when he took one of the leads off and plugged a spark plug in the end, it would fire when earthed and the engine was firing also....

I dont know how this could be possible though, as Ive not touched any of the earths for weeks and weeks....
 
Re: Mk1 Hybrid Project

yeah gona try it in the morning, if not get a multi meter on the case.....only other thing then i guess is coilpack!
