Turbo installations
Discussion
I really want to pick someone's brains who has done one from scratch and doesn't mind sharing their expereiences or expaining why they did certain things.
The engine is going in a kit which will explain why I want to do it myself.... but as the engine is a BMW V12 there are limited tuners anyhow.
The engine is a 5.0L V12, 8.8:1cr (std)... I am junking the fuel and ignition and replacing it with a full managment system with a coil per cylinder. I plan for twin turbo's and am having a free flow manifold made. It'll also have a dry sump and twin intercoolers.
Comments, advice, obvious flaws in my plan gratefully accepted.

Thanks a lot guys..... I'll definatelly be buying some books.
I had plan to use std cr and slowly build the boost as the mapping gets better.
My power aims are not that high (400-450bhpish) but I'll take as much as I can reliably.
DINAN the US BMW tuner use std cr (8.8:1) and all std internals and 10psi to get nearly 500bhp and over 540ft'lb torque.
Cheers

My understanding is that small blowers would keep the power lower in the power band.....
What I really want is for a power band of about 3500-7000rpm... this will mean raising the std rev limit for the car from 6000rpm due to the std car being an auto only.
Not a problem as I am told they can run to 8500rpm if done right. This is another reason why I went for the shorter stroke BMW V12.
My idea is that my cossie runs a 4pot 2L engine with a T3.4 and I prefer that to when it was 'only' a T3 (with almost same power).
So if I run a T3.4 on each bank thats 6pot 2.5L per turbo it should spin it up even easier.
Thus I hope that as this car will be lighter than the cossie and more than twice the engine off boost it should still be extremelly livelly before lag.
So by running the larger turbo (no more boost though) it will help me move the power band higher..... flawed plan?
