Interesting plug, never heard of them before. Well Pete, hopefully its all good. Was there much engine damage?

Wow, it really has done a number on those plugs!
Is it oil on the thread of the 4th one?
Or is that just a trick of the light?
The others just look terrible TBH, I cant believe it managed to eat them that badly in so few miles.
Were they checked after mapping? (ie do you know if the damage occurred during mapping or when used on the track?)
Am going to be very surprised if its managed to do that to the plugs (the ones with the missing electrode have probably seen 800+ degrees sustained electrode temp, and on a 197 plug thats quite hard as they have minimal insulation so a lot of chance to conduct heat away into the head) and then not done any damage to the pistons but looking at the fact there isnt any visible aluminium deposit on this one:
You may just be the luckiest person alive and have gotten away with it despite what conditions were clearly like in the combustion chamber!

Blimey Pete you do have some bad luck with your car. I hope this is an easy fix and its up and running again soon.
A bit of non car work today;
Finally got rid of Harry and Scarlett's play area - 8m x 5m weed membrane, play barked with climbing frame, both too old for the frame and never used it. Sold the frame a while ago and been moving the 50 barrow loads of play bark over the last few weekends.
Today was the final push - dig over, grade and level ready for grass seed.
Started the dig over - hard going after 7 years being a play area.
30 mins later - fist dig over complete
1st grade complete and part way through 2nd grading
3rd grade and flattened all ready for grass seed.
All by hand and done in 5-6 hours and I'm all done in too!

Nice going mate, bet it was a good workout
None that I've seen
Oil on all the threads on #'s 1,3 & 4 . #2 had oil just on the top half of the threads.
I never took the plugs out when I had the car back so I wouldn't know their condition, post Silverstone race Nov 2013 to pre Snetterton March 2014.
Fingers crossed, cheers Andy.
I'm feeling it more today!
So, got the results of the compression, leak down and bore scope tests
Compression;
Cyl 1 225
Cyl 2 190
Cyl 3 160
Cyl 4 200
Leak down;
I didn't compare the needle's movement between each cylinder, the green area is over 20% of the gauge scale - saw this after clearing it all away. So may be test results not valid?
Cyl 1 Needle in green
Cyl 2 Needle in green
Cyl 3 Needle in green
Cyl 4 Needle in green
And no visible damage\holes to the top of the pistons or scores to the bore when looking down bore scope.
Taking it to Dan tomorrow and hopefully won't be a major load of work to sort.
Weird that the leakdown was green while one cylinder is showing such low compression (and 2 others down a fair bit), did you do the test a couple of times to rule out errors in your test procedure?
Ironic that cylinder 1 has come back with the only sensible result considering its plug seems to have faired the worst.
Good news no sign of issues on the pistons, you may well be the luckiest guy on here if you have got away with the pistons in one piece, although that makes a mystery of where you compression has gone of course.

Only did the Leak down test once - I'll probably say user error as much as anything skewed the results.
Yes, would have thought #4 would've had the best results overall.
I guess the only way to be 100% sure is to get the head off. Once Dan's done his tests at least there'll be two sets for comparison from different equipment etc before any drastic work is carried out.
Yeah if the values for compression you have given there are anywhere near accurate, than without a doubt its a henry the eighth moment!
Ah, head off -took me a while to figure that one out..
Maybe because if it was detonating it took the plug out before doing any damage to the piston.
Possibly mate, I'm sure all will become apparent once the head is off.
Thought long and hard over an offer of using one of James's spare engines (that he kindly offered to lend me) and if I had a standard map file that I could use I more than likely would've taken him up on the offer. With the problem of getting it mapped - and getting a test day in during working hours next week, too little time to get sorted.
Gutted missing the opening Rockingham race being it's a French only race even more so.

Yeah the last thing you want it to wreck his engine as well, so I can totally see where you are coming from with that decision.
That is a real shame about missing the first race after so much preperation work over the winter, I know how gutted I feel when I have to miss a trackday so can only imagine how much worse that is when you know its a guarantee of no championship points etc as well as missing your day out.
Hope you havent had to pay the entry fee yet as that would be even more of a kick in the balls!
That's a shame Pete, but, a standard engine and a basic map would still be worth it right? Shame your missing it.
I'll get a spare engine sorted when not in such a rush - be easier in the long run.
Plus just sold my test day that I bought for £150 inc a garage on the 4th at Rockingham to Tony...gutted, what a saving on £275 normal price too!

Pete you need to send me your bank details again, so I can pay you for the above.

Sorry to see Pete 
You still going along? Or it will it be too painful to watch...

Ians selling a nice little race ready 106 for £1500, tempting to keep as a spare actually.
If you think of the full costs involved in fitting and mapping a standard engine for the one day, its going to be a lot of time and hassle, and then be way off the pace?
182cup & 172 racecar
Hence why the 106 would be cheaper option.
Yeah, would make far more sense to buy a race ready car for 1500 quid and use that, even if you had to sell it on a few hundred quid cheaper to get rid of it you still wouldnt lose anything like you would fitting another engine for one event including all the mapping etc.
I'll txt\pm you
Sorry to see Pete

Yes - considering going on the 4th - Friday too or at least the PM
Been looking at Matt's Spencer's Pug - the Green one 2.5 - 3k with a decent trailer too. Unfortunately got 8k lying around which is meant to be another overpayment on the mortgage...looked at a few S2000's and Z4's over the past two weeks too.
But once the Cup is ready all these itchy feelings to get out driving will hopeful subside and I'll have put the 8K where it should probably be better off spent..lol.

4th? Thought the race was on the 5th - Saturday?
I'm planning being there on the 5th so be good to catch up if you're about.
PS. If I was you I'd make the £8k payment to the mortgage asap, removes temptation! Lol!

Furry muff. Up at the parents on the 4th, so I'll miss the nocturnal activity I'm afraid
..and? My engine was in and mapped 3 days before Spa and I was at the Donny race 3 days after Spa...just saying ;0
Fair one, rushing is not good, disrupts the karma and all that. Good deal on the test day Tony
And we all remember what happened the last time I rushed to get ready for last years Rockingham race, doh!
not saying it cant be done, more a case of is it worth it just for one race and then all the expense be for nothing the moment you remove it and put the proper engine back in (once its fixed)
For sure when you look it like that. Well hoping it will get sorted soon Pete, just hate seeing ppl miss stuff like this due to car woes...shame.
Especially on a brand new engine
I'd imagine the main idea for going forged etc was the perception it would be MORE reliable, not less.
When is it coming apart so you know once and for all what you are facing in the way of repairing it?
It's with Dan at the moment (dropped of earlier this week) and I guess once he's done his own tests he'll work out a plan and get on with it. Not sure re timescales, apart from it won't be finished in time for the 4th 5th April.
Banana trivia;
Been cycling to work and back for 3 and a half years now , 225 working days in a year, 2 banana's a day (1 after AM ride and one before PM ride) that's 1575 banana's I've eaten (that's powered just under 13000 miles).
Wow...I'm saving the planet.

..and a lot of bananas....that's about 19 bags of sugar
Chase Racing Clio
13,000 in 3.5 years?? That's pretty good going Pete, how long is your commute and do you do it every day?
I've been covering about 2500 per year for the last year and a half now, but I don't cycle every day. 3 per week is about average, with my journey being 8.5 each way.
18 miles per day, do it every day come what may, missed about 5 days in 3.5 years...get some (door gunner in FMJ)!
Doing the math think my cat eye odo thing is under reading...
and using the Google average weight of a Banana (126gm) is 198.45kg or 437.5 lbs - 31 stone in old money...
also using the Google average grams of sugar in a Banana (12g) is 18.9 kg 40 lbs in old change, you were spot on Sonny - you into all this in some way?
