I'm not really worried about it..

Adding my two cents . . . . I too was going to post a similar post. I notice in the evenings and early morning my sd feels much different, more power and pickup. Something's going on for sure!

Yep, its what I said.

Any engine that burns more O2 will make more power untill detonation...

You'll need to explain how a slight increase in O2 will allow the engine to develop more power if there is no increase in fuel quantity...........??

A diesel already has much more air than it can possibly use in all operating modes except maximum power. At the max. power point, the fuel delivered should just barely match the available air.

Naturally, since combustion of the available air is not perfect when the air is limited (and it is limited when the available fuel just matches it), the engine will produce slightly more power and the ET might be slightly less.........because all the fuel can now be combusted.

But, this effect is slight, and certainly will not apply under part "throttle" conditions.

Already explained it.


No NA eninge has 100% VE from the factory. NOT ONE.


Throttle position has nothing to do with it. There['s MORE O2 in the intake at all throttle positions.n Also already stated what the HP addidtions would be on a stock car...

Quit thinking like a g@sser! These are DIESELS, g@sser thinking does not work with these engines!

That was the case with my intercooler. It didn't add any significant power under boost with stock fuel settings and it didn't provide any benefit at all at part throttle. I removed it to simplify plumbing and reduce boost lag.

I'm afraid that you did not explain it.

As previously stated, a diesel runs on excess air..........the engine has much more air than it can possibly use at all operating conditions other than maximum power.

So, again, provide some reasonable explanation of how a diesel produces more power with more air.........and not any more fuel..........under part throttle conditions.........

Already did.

For a g@s engine, yes. I have yet to see you post anything that relates to diesels.

Clearly, you don't have the info.

OK.........we're done here.
