Dual IPR block. Need help

[m j]

when is the next one available?

 

[Magnum PD]

Again, ask gwhunter

 

[gwunter]

We've been in contact. We will get something worked out.

I’m here for help

did you read through this?

[Magnum PD]

Thanks for that. Looks like Gates Megatech 3000 hose is the one to get. But where to get it?

 

[Magnum PD]

Napa can get it but, 50’ roll and $10 a foot

Call or message corey at cnc fab. He has the line you need.

 

[Magnum PD]

He has hard lines?

 

[dsberman94]

I’m sure he has hard lines but I asked him about making me some HPO hard lines a little while back and he steered me away from it stating the ends will eventually crack. I bought his HPO and HPX lines after that. I don’t remember but It says in the website what they’re rated at which is well over what we require for this application.

 

[Magnum PD]

I can’t find him on the members list so you’ll have to get a link for me.

 

[Magnum PD]

I got the website. I don’t see why I can’t use their Super dooper replacement kit for my needs. Still not sure where to put the bleed off line. My HPOP access bolt cover that came from Dyno proven has an access plug I could maybe use.

hucorey ?

Do I just solder on another IPR pigtail on the stock wires?

IIRC, the IPR valves must be wired in series, not parallel.

 

[Magnum PD]

Big help! Thanks

I had lines made local for my old BTS dual hpop. Aeroquip I believe. Based my research off of CNC’s lines he sells. Rated for both pressure and temperature higher than needed. They were blue. Don’t remember the model though.

 

[Magnum PD]

What does it do if I did wire it parallel?

Trip your cel and reduce pressure.

Just wire it in series and take his advice.

 

[ja_cain]

Current draw will be doubled if wired in parallel. The PWM drive circuit probably can't handle this. IPR will max out well before max output voltage is applied. The IPR's should perform fine even when max delivered voltage is halved by wiring them in series. This is just a theory. You potentially recover lost resolution too by doing it this way as the voltage range required to open the IPR's doubles. You will need this because the effective cv doubles by going to two valves.

To summarize, I think it's a current draw and resolution thing.
