Seriously tho.... when does forced air become too much air?

In a diesel, it doesn't.

In a diesel, it doesn't.

So the more air, the better? What about head pressure?

i was just going to say that there a few that run water/meth or straight water, there is a fair bit of info on that other patrol forum . mainly the straight water lowers egt's

Good question. I guess as with a turbo on a petrol engine you have to use a thicker head gasket, but I don't know for diesels. There would have to be a limit for a stock engine, then you would have to modify it by using stronger pistons, rods etc.

It depends on the engine and how it is built, if you want to run more than 80 psi in your 5.9L cummins you really want to consider upgrading to ARP bolts and studs, If you were going as far as 150 psi you would likely let the moths out of the wallet and upgrade everthing.

A TD wont handle anywhere near that boost

wasnt the thicker head gasket on petrol the cheap way to lower compression for the turbo, thats what I thought anyway

Exactly...

So after all of this, if you could design the perfect diesel engine, or modify a suitable candidate, what would you do? With my very limited knowledge, I would want high pressure air induction (Higher combustion/ cleaner burn/ less emission) coupled with water injection (reduce temps). Air/fuel/water mix would have to be spot on....

Sound right or way off? And why is diesel/gas combo a cheap way to increase HP?

[mudnut]

The gas injection increases the burn rate of diesel from 75 to 80% to a claimed 98%

After being "diffed" a couple of times I thought that running separate brake lines to all four wheels and having two thick rollers each side of diff on the rear and one wide one on the front. This way you've got a chance to claw your way of deep ruts and over rocks.

The rollers would be in two halves so installment would be simple.
