from FAQ just to show yes i'm trying to read: "12. Nitrous Oxide
Not normally suitable for a diesel engine. Since diesel engines normally run lean (except when belching black smoke!) adding more oxidizer isn't going to accomplish anything. If the engine is over-fueled due to extensive other modifications, then this might help power output ... for a little while, until something breaks."
Assuming i'm building a strong enough engine (like a BHW/ALH hybrid with upgraded rods and pistons and such)
And assuming I only want temporary power over the 'normal limit', like maybe I have a turbo limited to 150hp, and i'd like 180hp but not so often it justifies the further upgrade cost.
Would nitrous help me do this on a diesel to avoid the turbo running out of breath? In theory i'd assume yes just wondering if there's any challenges to this...
What about the water/methanol injection? This would cool the EGT for sure, but without extra air and oxygen I don't know if that does much good, or only a tiny bit of good. I know diesels need enough air to support the fuel, but i've also read of cases where a different fuel (like CNG) can help the primary diesel fuel burn better and more completely, though I dont know if that happens with methanol, or whether it's a miniscule (like 5hp) or nontrivial difference. (like 30hp)
