I have some spare S62 heads if you looking for some.:thumbs:

This would help some cuz my dad did say with porting and flowing he needs to find the physical mmax of the head without hitting water or oil jackets. So a spear set would be dandy. How much ?

This will be and interesting thread............. reminds me of the ends Mclaren went to to get the BMW V12 into that car................I have yet to hear anyone successfully replicating it .............GOOD LUCK :idea::joy:

And even BMW didnt get it quiet right, I was overweight by Mclarens spec.

Yup but the amount of power it developed was something like 125HP more than Mclaren wanted so they couldn't really say no to it could they....:rollsmile:

Ze engine is still over veight vat are we going to do Mclaren vill not be happy...

just make more power they vill forget about the veight :rollsmile:

I have 2 x right banks and 1 x left bank. Left bank has damaged valves on the last cylinder, can be fixed though. Or you can cut it up into sections to see how much meat you can grind out of it. R4k for all 3 heads.

Come people, stay on track here, S62 remember....not who is the biggest IT nerd with no life, girlfriend, social skills or tan...:nonono:

Now onto the engine.

The problem is making any engine generate huge power out of N/A it will cost 2 or 3 times as much to do it with forced induction, it also needs huge revs to do so.

So there even more were and tear on the engine.

There is a engine called 4AGE from toyota and it was used in the Toyota Atlantic racing series in the USA and the crank shaft alone was 5000$ in the mid 90's.

It's 1600cc Motor that revs to 12000 RPM and makes 250 BHP.

Now if you look at todays engines that are turbo charged make far power and far more reliably.

I doubt that engine could rev high enough to get the power needed with out blowing something or building it to do so would cost more than the car.

There is a reason why F1 Cars rev to 19 000 RPM and only last 2 races.
I would either twin turbo it or super charge it.

You can build it for N/A but you will far exceed 100k to do so considering it costs about 80k for a basic turbo kit.

Back to topic. S62 im aware of most of the above. My old man said it would need a new crank cut and balenced acording to new rods and pods. This wil give it the revs it needs and lower vibration. Also springs and cams to cope with higher rpm. A dry sump setup. My dad said he wil look into a bearing setup for cams and crank thats verry similar to bike engines wher it runs on ball or needel bearings
To lower internal friction. Also thinking of changing the shape of the head to inprove flop and lower the chance of detontion. What is the highest c/r u can go on normal pump fuel ?. Dads got the motor on a graphic desighn program to see where all he can inprove. To get a genral plot of the job he needs to do. And i said come close to ascari power not pass it so if ascari can make it last long with 625hp im shure it wont go bang within a hour or 3 with 550+- if u do a proper job at it.

Man up and STFU if you don't have CONSTRUCTIVE INSIGHT!!!:thumbdo:

Back on topic. To create that amount of power in the S62 is about 2 things, air flow, and RPM. You need to get it to breathe at higher RPMs. So head work would be your main concern. I think vanos is a good thing to get your engine to idle properly, but it would cost you a lot of development to design it to operate at high RPM. I would think it would be easier to junk it. But it will cost you in low end smoothness. I suspect your dad would know all this. There is no easy way, but with enough time it can be done. Your engine could do about 50 000km if you sort all the gremlins out. Lubrication and temperature control is the key to this. I still think it can be done.

Please document everything well. It could get interesting

Regards
Jacques

you could run water injection to solve the detonation problem and keep running costs lower...

I think you need to do alot more research into the ascari engine you want to copy no point in trying to figure out what they did if you can just find the info and copy it...

who is going to tune this for you? tuning will also be a big factor that you need done right :)

As far as I know the only thing untouched on the Ascari engine is the Block.The engine was blueprinted and balanced and they changed to a dry sump setup.They obviously changed the internals(raise compression and decrease inertia weight)and worked the head(bigger valves,port and polish).I think the cams will set you back quite a bit.The original intake will be too restrictive,the one that they used on the Ascari won't even fit under the M5 hood.I would'nt be surprised if they either used different throttles or modified the original throttles for optimum airflow.I'm shure they upgraded the fuel pump as well.Apart from everything else these mods will probably give you the biggest headache.Good luck and keep us posted on your progress.
