try some of the ideas that the F1 engines were using to get high power. I mean come on 1000+hp from 1.5L
not that you will ever get it that high with a 3 main crank and the head, as good as GRs is, but their ideas are good. Most of the early F1 turbo engines were 4cyl until Renault came along with the V6.
1st thing is high boost causes high temps in all the wrong places, especially pistons. What about fitting some kind of oil squirter system to squirt oil to the base of the pistons. Many modern lean running NA engines already have oil squirters, so you can perhaps adapt some. all you need is enough supply and somewhere to mount them that does not get swiped by the rods or counter weights - not easy, as you can't lose pressure from the rest of the system when you add these.
The F1 engines actually ran really over rich to help cool the pistons. Look at any of the photos of the era where the angle is right and you will see black smoke billowing from the exhausts. at which boost it becomes an advantage to go from lean for power to rich for cooling is probably a matter of experimentation.
can't remember much more, but i am sure if you look up the technology of the era you can find some stuff that has disappeared from the turbo knowledge base, because many of the 1/4 mile guys are looking at short duration high power, not sustained high power for a GP, so would not be applying the same ideas.
