What Engine for 500BHP

I once had an oil/water heat exchanger fail, but not in a car... but in a multi machine manufacturing unit. I feel your pain.
But we had to deal with 200 liters of oil in the machine which was contaminated but also had over 2000 liters of water that had a couple of liters of oil in for good measure
Draining the water without shutting down the plant wasnt an option, we had to keep running and we had to clean the oil out. Fortunately the oil floats to the top, we had special soak pads that absorbed the oil and not the water. It took a good 24 hours but eventually we cleaned the oil out of the water.
I did something similar recently with a Golf with a contaminated water system, After flushing the block and rad with clean water through a hose, running the engine with the cap off made the oil come to the surface of the expansion tank. Dipping a strong tissue into the water would pull the oil off the surface of the water to get the final dreggs of oil from the system.
I think we have somthing similar at work, they might be good to put in the expansion tank, to keep the oil that makes its way there in there, so its easy to get out.... Been overflowing the tank today and got a good bit of oil out, but no more time now, have to sort things out for work.....But we had to deal with 200 liters of oil in the machine which was contaminated but also had over 2000 liters of water that had a couple of liters of oil in for good measure

Handy hint for getting the oil out of waterways is to put household washing powder (or drop a tablet in) and then run the car up to temperature for a while. This turns all the oil into a white milky solution which no longer allows the oil droplets to stick to the insides of pipes in that salad cream type stuff you probably have atm after the water pump has whipped it up. It's then a case of running through the water system with a hose to flush out the milky solution and eventually you get back to clear water again.
Sounds crazy I know but use this method all the time when flushing through C20XE/LET engines after repair from pourous heads for example
I had thought of using a degreaser/ emulsifier at some point in the cleaning process, so I guess if washing powder works, then a degreaser should as well...Sounds crazy I know but use this method all the time when flushing through C20XE/LET engines after repair from pourous heads for example
Managed yesterday to warm the water out of the oil & have mow changed the oil, what came out looked pretty water free, but there was only 5L of the 6 i filled, so a whole litre of oil in the water system!

Well I am Back Home Finally, Got a c0uple of small items from the US while i was there, as they were cheap, on the right is a new throttle pulley, a smaller one to clear the chassis. I was going to make one, but this one was only $15, so its nor really worth the effort to make one.
the one on the left is probably not legal for a road car, so best not say what it is... I am sure some one will hazard a guess though.
Got a few jobs around the house to do, then hopefully I can get the car on the road reasonably soon. Its the cleaning out the water & oil mixture from the cooling system that I am really looking forward to

Done some flushing of the cooling system today, Poored 1/2 litre of muc off into the headder tank and let it circulate. (yesterday I drained 1/2 litre of oil from the headder tank.)
This seemed to emulsify the oil & water into a nice white milk, which was then flushed out by continously adding clean water and draining at the same time with teh engine running. This was continued until the water was clear... It helps having the electric pumps as I dont need to run the engine to circulate the water.
It seemed to work pretty well, but I will do it again when I have fixed the oil cooler.
Took the cooler off & spotted the problem straight away...
The O-ring had blown as suspected.
I am going to have to confess that it was my fault..... as I had put the o-ring on before the gasket, instead of teh gasket & then the o-ring. DOH!
Still At least when I put it together propperly this time I wont be worried about the same happening again!

Looks a poor design to me as the O ring has nothing to push against at those 2 points.
Thats because I screwed up and put the oring the wrong side of the gasket (still real mad at myself for that)....if assembled properly it looks like this, fully supported all the way around.
Well the car is still at the dyno.... it went in to sort out the transient throttle, and a missfire when cold. The missfire became worse before it got there and the engine just wouldnt rev above 3500....
Problem was diagnosed as the crank sensor failing , but it took a week to get a new one, now I believe it is running fine up to full rpm, only its blown the fuel pump fuse twice now
Thansient throttle hasnt been sorted yet, as the industrial estate has been burried in snow all week & it needs to be driven on the road!
On a plus it is now running 480BHP at the wheels, so 5BHP up and at a slightly lower boost. So it should be relatively easy to get 500 at the wheels if i want
for now i will just be happy to get it back. Its booked for a full suspension alignment check in a couple of weeks and then a track day at the end of April....

It is now running 490RWHP @ 1.2 bar boost having had the map tidied up a bit and a new crank pickup...
Good job done by AET Motorsport
They have some video of it as well, hopefully they will post it soon... maybe if they get enough likes...
