This bit on the left me thinks.
Ah oh that's fine it's thick wire reinforced. The white bands have wire under them

It's always been like that. What would you do craft a solid ally pipe and run it round the side?

Nice build, i always thought it was ducting and not for intake pipes , unless this is different stuff,

I shall investigate a better solution.

By using the insainly expensive but slick pre wired option I think: http://www.demon-tweeks.co.uk/motor...cessories/lifeline-quick-release-bolt-on-boss

Yes I do have that Lifeline boss for the quick release system but for the buttons I have this system.

It's a wifi 4 button switch panel, Mine is the 4 not the 4s with the little lap timer on it.
I found a new life line boss to have play.
On the other hand, I've used a d1 spec boss and it was brilliant, never had any play atall.

p**n p**n everywhere !
That sucks, so I have this to look forward to as well then
I cant comment on there long term lifespan but I`ve welded 3 of those bosses onto various colomns in the past and have to say from new they seem a very very good fit, certainly no play from new.....

Hi Guys
Am I right on these rings gaps for my woosner pistons?
Bore 82.5mm
Top ring = .006" x bore at 82.5mm = 0.495" thou
Second ring = .006" x bore at 82.5mm = 0.495" thou
Oil ring = .015" x bore at 82.5mm = 1.2375" thou
is that correct or should that be mm and not thou?

So A brief race report. LOL
Saturday the car presented itself with a range of electrical faults that kept changing every 30 mins. Much consternation ensued and also much changing of everything we could think of and then changing it again. I missed scrutineering and then qualifying and then the race and we kept at it. I was pissed
OFF
12 hours later Rob and I sat looking at each other and I said what havnt we checked. The relays he says. OK lets check em. He sticks his head behind the panel they are mounted on and says hmm there is a big thick earth wire here mounted onto a bulkhead bolt. Hmm the 13mm nut is loose on it.
Tighten it up and et voila everything works.
MORAL:
NEVER GIVE UP
LESSON:
Electricity is like magic and I f**king hate it, a lot.
Sunday.
The starter motor I bought on Saturday as part of the things we changed won't engage and needs modyfying so Rob starts to do that. He then sits in the car and presses the brake pedal 15 mins before we go to scrutineering and says to me should the brake pedal go to the floor like that. No I say, I look in the back and one of the rear brake lines has come off and shed all its fluid in the car. I run up to scrutineering to ask if we can be late while they fix it and bleed the rear brakes in 15 mins flat!!!!
We pass scrutineering and I set about qualifying. I have new front pads so did the first 5 laps quite slowly so as not to glaze them up and then pit. We check tire pressures and I set off again and start to push on, the power steering rack fails again! Smoke everywhere and I have to pit again, session over and back for repairs.
Quali in 41st LOL out of 44 My teamate and partner Darren is on Pole and I am at the back which is a very novel experience for me I can tell you. He laughs. A lot.
Back to the pits and we discover the rack has the wrong fluid in it and we can't fix it. Ill drive it with a manual rack I say to which I get some guarded looks! Now I know why.
Race on and we are off. I settle in at the back and start to pick people off wrenching my arms from my sockets as I struggle to turn in. It's actually a very good experience as you get to learn to handle lots of traffic which you don't get from the front. We do our pit and I am in 20th I think and moving through the field. The car is overheating for some reason and I notice the alarm on my dash at 125c and slow down and do the lap back to the pits. The car cuts out as I pull in and race over. I will strip the enigne now to check its ok and figure out why it keeps overheating, air lock we think.
So all in all a great weekend which I enjoyed a lot. I did a grand total of 15 laps and it has cost 15 MSU's in total which in motorport terms is good value for money!
The car is actually very fast and now I can develop it, fix the issues we teased out of it and put it on pole in 6 weeks time at Silverstone. God I LOVE motorsport a LOT.
Engine Strip
Big end destroyed
Rod fucked and both either side according to Arrow
Block fucked
Piston busted
Piston hit head underside fucked
Great
Total rebuild

Don't ignore your f**king alarms you f**king moron just because you're enjoying yourself on a hot day

Lol Mark!!
Welcome back to motorsport, sounds like a very eventful (expensive) day. When ours blew, all the gauges were saying STOP!!, but I knew it was past saving, so just kept going.
If I'm free on your Silverstone outing, I'll come and say hi.
What's the date?

Id gone from 41st to 19th by the pit and was really enjoying myself and just sort of thought if I ignore it it will cool down ROFL. 7th Sept Tony. Be great to see you. making loads of improvments with this rebuild so should be much better.
Ceramic coated Turbo, Mani and downpipe
Electric water pump
Evans waterless coolant
Vented bonnet
19 row oil cooler
Remove water cooled audi oil cooler
Bit more heat shielding
That lot should sort my overheat issues out nicely.
A friend of mine had issues with the water pump on his audi TT, the vanes came loose?? Or span in the shaft??
I cant remember exactly now...
Definatly sounds like a catalogue of gremlins for you... onwards and upwards as they say!!

A new block nicely honed
A new crank nicely polished
New Woosner rings
New Arrow rods
ACL race bearings
Pistons all cleaned up and shiney
All my ceramic coating stuff back
Leccy water pump
BIG build this weekend.

So some more pictures for you.
A nice shot of the mess you make when you overheat an engine! Dont do it.
The piston had hit the head as you can see
And knackered the crank too
And then bust the piston
And the rod for good measure
My new engine block BWA £195 quid non runner. A risk
A vaneless water pump
I dont think I will have a heat issue anymore
A hopefully metal free oil filter housing
My new crank fitted. This had the smaller oil pump chain wheel on it. So I pulled it off with my puller and tapped on the AXX bigger one.
More to follow...

Bugger. went to fit the cams on Friday and noticed for the first time that two lobes have gone to points So I need two new cams as well pooo. Sending them off to CatCams today in Belgium. My lifters are also scored so I will put a new set of those in while I'm at it.
As far as engine blow ups go I don't do things by half's it seems :banghead:

I now know why in F1 they are so keen to tell them to stop and turn it off before it blows LOL. Lesson learned.
