The motor failed simply because CNC heads did not do the line bore correctly, the 2 middle main saddles were out of line, the motor failed after I lo9st a plug tip at bruntingthorpe and scored the bore, because it was almost impossible to find the cause it was put down to the scored bore and material in the oil, I had no argument to counter this so just had the second engine built, I was on a time line as were going on the B35 tour to Norway, CNC heads did not do anything to my engine as they were filming car SOS !!!! So 3 months in with weeks to go I started kicking off, the engine builder got on CNC heads back and soon had a call saying block done new liners etc, I can tell from what was said that they had purchased and fitted and machined the liners and not even checked the bottom end to see if it was even serviceable! So builder told oh we need another few days, they pick the motor up and start building, about midnite I get a call saying they cant get the clearances they want and motor going back to CNC heads and they will wait for it. Apparently they hand polished the crank to get clearances !!!!! Back to the shop and the guy laying it all out on the bench noticed something interesting, the witness marks from girdle and block from first failure were still there! So how did they re alignbore it? Anyway crank was put in clearances achieved and I picked motor up, put it in car ran it on the sat before leaving fri for Norway, we had a few teething problems and could not drive the car till weds, Dimitri put a map on it weds evening, very toned down to get some miles on the car and he would remote map as it was going across Europe.
He said do a decent pull to check the fueling and the oil pressure dicked around, I spoke to builder and we both concluded the sender was iffy, went to 4 bar and stopped dead, did 3400 miles inc that in GB in 8 days, put car on dyno and it was 675whp, we turned it up and got 1101whp @ 2.1 bar must have had over 20 pulls as a VVTI solenoid was faulty and Dimitri was asking for far more % than usual to achieve what he wanted, got back to shop and Imran next door had a solenoid so we fitted that and road mapped it to 2.6 bar the night before TOTB
First run at 1.6 bar it tripped as it went into 3 due to seeing to low a pressure vs RPM, when stripped the 2 middle main bearings were identical.
I claimed on the builders Liability insurance as their Insurance company would claim against CNC heads insurance, they had a forensic engineer (******) who looked at it but knew what to look for as I had sent videos of it being measured and a clock run over the surfaces, it then went to be measured on a machine that could be used as evidence in a court case and the problem was found to be faulty align bore and not a result of negligence of the builder (remember they cant check the align bore, the people the asked to check it are the people who did it)
I firmly believe that CNC heads never did the second align bore at all and just sent the motor back.
Oh and to add insult to injury all the liners the idiots fitted had pulled into the block so it would have hydraulic-ed anyway eventually.
So CNC heads bunch of clowns Ric Wood absolute pRic and I hope the insurance company sueing you get every penny because you dont even do the align bore you sub it out and double the price to the customer so good luck coming up with a invoice so your company can sue the people you use (name witheld) who I know exactly who they are.
So thanks to CNC heads I have been without my car for almost a total of 2 years.
