Quadzilla Adrenaline V2 Testing

There's definitely more out there but question is how much and at what cost.  I wonder if someone has a PM3 that we could borrow to see what they are running in the higher RPMs.  I've always heard good things about their fueling past 3200.

I've got a TST comp. The PM3 dies off like a stock truck does, but the comp keeps fueling. It is also likes to surge on the high numbers and doesn't rev as high as they claim. What year is your truck @Carbur8tr?

It's really a balancing act to see how long canbus fueling can be held up past 3200.  If you look at the truck wrong with revs that high holding canbus fueling it just shuts off.

 

 

I'll get it nailed down.

I also want to point out that is it now possible to mechanically advance the pump by 5*, 1 tooth, and pull back timing in your Quad by 5* down low while keeping timing high up top.  You will effectively get a very controlled ~35* of timing if you choose to.  It would idle funky, but once you got on the throttle I don't think there would be an issue.

I wonder if this will actually work. Could explain the reason monster pump trucks idle the way they do, physically advanced timing in the pump.

[Me78569]

I don't see why not, the VP44 doesn't know it's actual mechanical timing,  it just gets a timing command from the ecm and does it.  If it is mechanically advanced by 5* then you tell it to do a timing value it will aways be a* + ecm timing =  total timing.

 

I won't try it, but surely someone wants to haha.  Heck if someone wnated to try I would even write them a tune that idle'd at 7* vs the normal 12*

The gear advanced has been tried before, but not with the control that is available now. Anyone want to trade for 97 12v!? I'll be the guinea pig LOL. Not being a smartbutt but have you been around a monster pumped truck? Totally different experience than a stock pump.

Never even heard one run haha.

Think small block chevy with too much cam and not enough cylinder head lol

Let me know if you want to play with the TST.

I don't think so considering they idle at over 20* when cold. Who knows what's really going on inside them. 

[Me78569]

truth.  Wonder what a warm truck would idle like at 20*?  I know when I tried to idle a cold truck at 11* it wouldn't have it....  

[Carbur8tr]

Soo how hard would it be to advance the key?  Are we talking like vp needs to come out and rotated.  Excuse my ignorance, I've only messed with timing on a 7100, I imagine it's similar just not visualizing it right now.

[Me78569]

no idea haha, I would assume you would need to pull the cover and rotate the entire vp gear 1 tooth advanced.  Doesn't sound fun to me, but yea I guess someone might want that.

Change the keys. There is a whole mess of key available for changing the offset of the pump shaft.

 

[Carbur8tr]

Next question, what do the keys correspond to? Timing would be the obvious answer but to what degree?

Can someone explain to me how a keyway would alter timing more than a % of a * ?   I have always been confused on that.

[Mopar1973Man]

Now the best I could say is get ahold of Blue Chip and ask him how much timing offset you can get from one end to the other.

[TFaoro]

Changing the key isn't going to make a big enough difference to even notice. I would pretty much guarantee that. 

Slipping a tooth does require pulling the front cover off. It is impossible to slip a tooth without the gear being outside the housing. 

I would do it but that seems like a lot of work for no gain considering we can get to 30* now. Mine doesn't like over 22-23 @2000 rpm anyway. Makes it give a gentle surge with higher timing than 23* that @Me78569 swore was my truck and not the quad
