It was 20 minutes practice, and then 2 30 minute race stints
my first stint was shortened by the safety car. Yeah it was only the first stint that was affected with the gearbox and then we fixed the mount so not too bad!
Yes I thought defending a bit too aggressively but was quite good fun! Its tricky to battle like that and also keep an eye on the pit wall, and for the stupidly quick stuff coming through
Great stuff Andrew
Doh!
It had a good innings and it was showing signs of been tired!
I thought it was going to set on fire but thankfully it didn't.

Not good at all.Anything salvageable?

Depends where the pistons finished up after the Elvis Presley conrod made a bid for freedom and how much oil starvation the rest of its seen.
Potential for the head and cams to be safe, maybe a bent valve or 16 and the pistons could be reused, but that is purely based on where it was in the cycle when the conrod left the building. I'd hazard a guess they're like a prostitute though tbh. Well fucked.
Or it could all be fit for the scrap bin.
Just had a look at the video and data from the engine going bang and there was nothing to suggest a problem other than when I started to hear a clicking and I slowed down the oil temp gained temperature very quickly until it went bang. There was no oil pressure drop, no oil starvation in the session (I wondered if it had lost pressure through Corum) so it seems just a bearing gone which has caused big heat and then rod out of the block.
No it just span the centre main it seems which then span the big end on cyl 2 and the heat etc snapped the rod bolt. Yes this was std 140K mile old rods with Supertech pistons
As Mark says but doubt it unfortunately, unlike my last engine that went bang at Spa this was quite a drawn out affair so guess its done the head/cams etc but will only know for sure when I take the engine apart

Crack on then! Lol
For Sale:
Selling a few bits to make way for some new bits over winter so thought i’d put them on here before doing a proper advert at the weekend!
First up is the Catcams Solid lifter, finger follower cam kit. This includes all the valve springs, cams, solid lifters, rockers etc. RRP is nearly £4000 including the vat and this kit is brand new unused for £2500 delivered.
Second up is the Gripper, straight cut dogbox. This was the single most useful addition to my car it transforms the way the car performs and gives a really nice set of ratios. I always said I could never go back to stock ratios after driving this box. The gearbox uses standard driveshafts, clutch etc so just is simply bolt in and go. It was built into a JC5 129 casing so has the speedo drive too. Since gripper have modified the crown wheel and pinion at the beginning of the year it has been absolutely faultless. It’s been well looked after with gear oil change after each use. Gear ratios are designed well with:
1st gear pulling 55mph
2nd 75mph
3rd 95mph
4th 115mph
5th 133mph
Not managed to hit the redline in 5th yet including some tracks with big long straights such as Silverstone GP, Spa etc its geared perfectly.
Again RRP from gripper including VAT is best part of 5K before you supply them a donor box i’m looking for £3750 delivered only selling to make way for sequential gearbox for future plans
Thanks
James

Refresh my memory on the cat cams kit james, the cams are specific to the lifter kit arent they? Do you know the specs, duration/lift etc? PM if you want,need to speak to you about those td pro races anyway.
Russ

Yes it's a full kit that cat cams put together I will dig out the details later and forward them over
no worries
Does the box include a gripper diff too?
Must resist...

Resistance is futile.
And yep, it includes a Gripper diff I believe. Although James will confirm no doubt.
No need to resist
Yes it has a gripper plated diff in the box with straight cut final drive
Gears gifts can be made with or without the clutch which saves a good amount of time but the main advantage is the gear ratios and also the fact you loose the terrible syncro's and have a sturdy proper motorsport box
195IB/FT it's effectively the same as a JC5 the weak point going more than that is the casing which is fundamentally the same with this box. I think the gears themselves will be fine at turbo level as we talked about using it for mine but the reason for me going turbo was because of the sequential.

And so the turbo powered sequential gearbox race Clio build begins!
Kind of wishing I hadn't blown money on other things and it was the other side of Christmas so I could take the box off you. Ah well I'm sure it'll go to someone who will use it more than me anyway!

Haha yes Tom first things first sell this stuff and order the Sadev and then go from there
Typical eh?!
Typical eh?!
Proper job!
From a general down shift or are you saying a proper over rev, like changing down too early and revving over the norm?
I guess James can confirm..

Proper job indeedy. Answers the 'salvage' question though...😂
At least Dan stayed and helped clean up
Thankfully for once it's pretty clear,
The centre main bearing has spun, this then blocks the hole for the oil feed to the crank and the rod on number 2 gets starved of oil and overheats (goes blue) and throws the rod when it's get to a certain temperature which is why the ARP's are blue and sheared.
All the data backs this up with a sudden increase in oil temp as it was trying to quench the overheating bearing.
No obvious sign of a pressure drop in the session to start the bearing spinning but it's a very common failure.
Solution is to tag the main bearing but if the bearing wants to still turn with enough force it will.
Head and cams have survived surprisingly

Hoorah on the head and cams. It looks pretty much fooked, so that is some silver lining I suppose
Bloody hell mate, was yours tagged?
For some reason I had flashbacks of Spa 2012!

By the time the oil temp has started to rise it's game over mate as the bearing has already spun and destroyed the crank and rod bearings closely followed by blueing the conrods.

A bit like the one I completely destroyed at Oulton a couple of years ago!! Nothing left at all lol.
