Huck, the decision is simple to me -- if you plan on going to B-codes or larger, the Adrenaline isn't enough. It will support up to 530 hybrids (where I'm going). If I EVER end up going more than that, it's because I'm putting all of that into a new block.

EDIT: DAMMIT!! I'm in Rep-Jail, Robin...
I'm just waiting to see the long term of the adrenaline. I like what I've read about it. Except where Bob says that no tuning changes are needed, but we all know that is bs...
Why do you think it's BS? If you're tuner is calling for 3000, and you're only getting 1700 or 1800 with a tired stock pump (like in MY case!!), it should be in the mid-2000s on stock split-shots or even closer to 3000 with just the pump change. There really SHOULDN'T be a tuning change -- the extra volume the Adrenaline provides means it won't drop as much on stock sticks, which is a really GOOD thing...
I've been to DieselSite to check out the Adrenaline HPOP. It claims it increases volume. When the say that, are they talking about the volume flow rate? If so, did they change the impeller to do so? By Bernoulli's Equation, if the volume flow rate is increased, isn't the pressure decreased? So is that how this pump allows many more mods? I've tried to explain this pump to my wife, but have been unsuccessful thus far.

I agree, there shouldn't be a tuning change. But. Most of the threads that I've read about the adrenaline have envolved changes in tuning. Why, I don't know??? Just what I've read from some adrenaline customers. Have you had a chance to talk to Tony about it?
If volume is increased, friction losses also increase but pumps create pressure so an increase in pumping volume will result in a net pressure increase, despite the added friction loss.
I don't know what he's changing, Jason. But it's kind of like electricity. If you have say, a 12VDC, 10A power supply, but the load wants 15A, the voltage drops. Just like with the HPOP. The tuner is calling for 3000psi, but the injectors want more volume than the pump can provide, so the pressure drops. With a higher volume pump, it provides more volume, so the pressure doesn't drop (as much). Make sense?

Then how is this good for the motor? Weren't the 6.9L IDI's high pressure, then when you slapped on a turbo, stuff started breaking?

Not yet. I wasn't even planning to until the North Texas event coming up in Oct. Right now, the plan is to put the pump in and see how it reacts. I'll definitely post up the results and whether or not any tuning changes are needed.
Because the additional pressure and flow are only created when asked for by the engine, not constantly. If the injectors need more pressure and volume than the stock pump can provide, changing to a pump that will provide what is being asked for isn't going to damage anything, since it's only on demand.

Apples to oranges, man. You're talking about taking a motor that was never designed with a turbo in mind and slapping one on it. In this case, we're taking a HPOP system that was designed to run at a certain PSI, but because of tuning changes, can't keep up with the volume so the pressure drops. With stock tunes, the pressure doesn't drop because there isn't nearly the volume of oil required to pump the fuel stock tunes call for.

Jason I explained it to my wife kinda like that also but she still want go for it. She said it want make my truck run faster, jump higher or smoke more. That just shows what she knows about it She said its time for her to get a mod she has new carpet samples on the counter, looks like thats were my new hpop $$ will go for now.
