stacked VA boxes on a 305!

Sorry,

I mentioned early on it's the VA CP3 Level 2, the Duration box stacked with and Edge EZ Pressure box.

bringing this back to the top with a couple of clarifications. First, thanks very much for all your thoughts and wishes on the surgery. I'm recovering now, can't drive yet, but as many of you know, general anethesia has a way of getting to you!



Anyway, back to the fun stuff. I wanted to point out two things re: the stacked combination:



1. With both the pressure box and the duration box all the way up, I actually don't expect to see the performance I'm looking for. Look at the dyno graphs for these boxes -- both are agresssive at the low end, backing off at the high end to protect EGTs. I expect the combination will feel a bit dissapointing -- just because the low end oomph, and the high end back-off, will be amplified when box boxes are stacked together. I haven't tested this, but I expect to accelerate nicely and then get let down as BOTH boxes throttle back. But thats not why I stacked these boxes.



2. I actually haven't tested the settings I'm most interested in -- both boxes on level 1. look at the torque curves -- both boxes are fairly flat in this position, so I expect the combination to be close to this as well -- just added together! The reason I haven't tested this is because one of my boxes came without the switch so I can only adjust one box at a time. So I'm not yet able to get away from that agressive low end followed by the top end backing off.



Hopefully this will work. If not, I'll have some conversations with Van Aaken! they have a real opportunity here I think and I hope they make the best of it.

I sent VA a note from thier website yesterday wondering if they could make a harness with one ecm connector and two pigtails, one for the duration box and one for the pressure box. Might be a neat setuip for stacking the two boxes.

good. I think they're already working on that, but its good to make the suggestion. another bonus they have is that they can make the harness such that only one box is doing boost fooling.

You recovered?

Doug,



How are ya??????? Did the surgury go okay?

 

[DLeno]

doing good! well enough to sleep and type that is surgery went good so now its just the recovery thing. procedure itself went longer than expected but no complications and I've got no more pinched nerve pain. very nice bonus. doc says I can drive in a week so we'll see about that . need to get that EGT gauge on!

Hey Doug-



Good to hear you are doing well. I've got an almost new (used only once ) 7/16 bit and 1/4" NPT tap you can use.

Doug...

Doug, glad that everything went well and your pain is gone. Sounds like it will be worth the recovery pain in the long run.



It's 12:30 on Tuesday and my gauges are going in as we speak. I will post ya some numbers tonight.



And yes, I farmed the job out. The wife didn't seem to see any priority in me getting them in (or making time to do it).
