It Begins: The S3 1.8T into my '85 Mk2 GTI

[sports racer]

Fixed?

[GOLFBALLS]

Nope.
A while back i got some water down in the fuseboard which caused the wipers to go nuts. I checked the fuel pump relay the other day and there was some pretty gnarly corrosion there and i thought i'd found my problem.
Anyway, roccodingo sorted another CE2 fusebox for me and after putting it in last night it has done four fifths of f#@*all.
Car is still misfiring and carrying on under load.

Then i disconnected the coilpack harness and found some cracked wires. I tried to fix them up and put a full set of coilpacks in just to make sure.

I'll test drive it tonight...

There's an old trick to see if your misfire is caused by faulty/worn sparkplug leads. Have a look under the bonnet in the dark with the engine running but no lights on, not even a streetlight. A dark garage works best. In the dark it's pretty easy to see any stray sparks jumping from the leads to something else.

yep a good trick! I'd forgotten that one. Obviously there's no spark leads here but you can probably do the same with a split coil pack harness.

BUUT, ITS FIXED!!!! After months of frustration its finally back to it's bangin' old self!

I changed the coil packs and taped up some of the suspect wires at the same time so i dunno which it was that was causing the issue, but right now i dont care!!

One difference is the violence of the off-throttle boost purging. I think its just because i've deleted all the stupid breather tubes, vacuum pipes, pcv stuff etc so there's nothing to absorb the pressure from the system (i havent put a catch can in yet, its just going into the air!!). But more on that later...

So back for a remap soon.

Thanks for the suggestions ppl

Now i can crack on with the engineering certificate...

Awesome! That's great news mate, you must be chuffed!

[ByronRichesMk1]

**** yesssss!

Been doing a few jobs in the lead up to racewars this weekend. New Ate discs all round with greenstuff front pads. I did the mk4 rear caliper conversion so I can use the later type rear pads. Now I have Ate ceramic pads on the rear too, as well as the goodridge braided hoses all round.
Back on the dyno tomorrow for a fine tune...

[GOLFBALLS]

Here's a random pic of the last car i'll be wrecking for a long time (too many spares and not enough room!). I now have most of the parts i want to tidy up the trim & bodywork, as the silver GTI was low k's and really tidy.



And here's the corroded fusebox! As i said before, it wasnt the cause of my misfire but it certainly needed replacing!!!

[sports racer]

So she's running all sweet now?

[GOLFBALLS]

Yep all sweet.
Its on the dyno as i type this just for a last fine tune before racewars.

[Jeats]

And what are the figures... Curious minds want to know

[GOLFBALLS]

Pretty happy with that. Running a peak of 19psi boost and hovering at around 17psi most of the time.
So, as you can see, approx 255bhp at the front wheels @ 6000rpm, torque peaking at around 270lb/ft @ 3500rpm. A nice smooth torque curve too.

Just put the catch can in. Just gotta finish off the hosing. Pics coming...

[sports racer]

Nice numbers - lots of usable power between 3500 and 6500. Must be really sweet to drive when you've got 3000 rpm as your window to play with.

hi Wade, I'll be spectating tomorrow at Racewars, so keep an eye out for me and say hi (as you race past as 250kph!! LOL)

Sweet! I doubt I'll be cracking beyond 220kph though...

Why arent you running the RS4?
