Making power in my F31 340i
Discussion
Unfortunately quite a boring update as I've not done anything interesting yet as I'm too much of a chicken to turn the power up at the moment. I have decided to send the car off to Williams Performance again late August to have the engine forged. There is quite a shopping list of stuff going into it and I'll make sure to get plenty of photos of the progress. I know it's a long journey to get work done but he is the only guy I will trust with making stuff happen on my car now.
I've been daily running it at this silly power level now for a couple of months and I'm fairly sure my luck will run out at some point. I do have a more powerful map I can run on the car which my tuner has said should drop my 5.18 to a 4.9X time due to the extra power and the way the power should come in but I've decided to play it a tiny bit safer and not risk wiping out my block just for that glory run.
The only annoyance at the moment is that my charge pipe coupler has decided to blow itself off a few times so I had to get another one sent out by Osprey Performance which has helped hold in the boost.
Oh actually, today I lost my parking sensors due to electrical gremlins. It might be heat related or it might be something else. I need to fire up ista and give the car a poking but it's too hot to mess around at the moment.

Time for another update: The car is at Williams Performance getting forged!
The timeline was pushed a bit due to reasons but the car is finally with Marc starting its jouney to "full send". The car was stripped of its engine
On the ramp
Oops catch can had oil in it... sorry floor!
Out you come...
From being on the ramp to having the engine on the floor was apparently 2hrs and a cup of tea. Not bad going.
Because that was a night shift it had to wait until the next day for the engine to move into the prep room to be cleaned up.
I was shocked to see so much crap in there considering the amount of meth I use.
Not a single bent rod. Useful!
Clean but not clean enough.
Off to be vapour cleaned to give a really clean foundation to start with.
I think the block is back with Marc today but I've not received any photos yet. Once it's with him will start the fun stuff.
I'll share details of what's going in once I've got more photos.

What sort of power are you hoping for roughly? 600+?
The car is running (I'd guess) low 700s at the moment. Forging is more for safety than anything at the moment but I'll crank fueling and boost up a tad more. I'm guessing mid 700s but the Dyno number doesn't interest me.ChrisC-340 said:
Launching a RWD car in 3c ambient temperature is rather tricky. I was faster that day than a number of cars that should be very quick. Each time there has been a session at pod for me to go to since I've been busy. I don't really want to launch it hard on the road as it just leaves clouds of smoke
You can see the 60ft was shocking, I was spinning to 70mph and the 0-60 was almost 4.3sec. getting a proper launch and the car is an easy ten second car.

You can tell its a 10 second car due to the 2022 terminal speed ie 132mph that should put you in the mid 10's providing you can launch hard enough and not break anything which is always the trick with drag racing
It's STILL not back with me but Williams Performance have been super mega busy so my work has been moved to more of an evening project.
The engine is back in the car as of this afternoon but I don't think it's running yet
Valves before and after cleaning. Not too shabby
Nice and clean!
Block all turbo'd up ready to be shoe-horned back into the car
Block is back in the car ready to have the rest plumbed in.
