-m = Molded coil option gives you 221F max operating temp.-h = Hi temp option gives you 356F max operating temp. I still dont think thats good enough for under the manifold. If there are other options I dont see them on fabcoairs website. Here is the link, bottom of first page.

Hey guys I'm new to the forums, but I have been lurking for a while and I thought id post some pics of my setup. I've been running it for 4 months with no problems.

 

Looks nice. Any details?

 

Well to date they have worked flawlessly. I think the only real downside is that you have to run longer vacume lines that may reduce responsiveness but i realy cant tell. I ended up running realys for each as they are very hevy duty and their wasent enough jucie to reliably switch them. I think the best part is the ability to diagnose problems without ripping off the uim. You simpy unplug all but one then turn the key on and listen for it click then move to the next. Its accually how i managed to fix my boost problem they had the pressure hose and the vacume hose swaped at the acuator so when i was manually triggering them it did nothing and i went from their. As far as the solenoids go i bought them off of ebay new, they are for big rigs not really sure for what though rated to 30psi, 180f and have viton seals. i was initially worried about the temp rating but where i have them mounted i can touch them after a long drive and the are just alittle warm (120 according to my temp gun) and was as hot as ive seen them go.

 

Somebody please start building these setups again.

 

Looks really tidy - Good job

 

Has anyone tried mounting them directly behind the UIM on the firewall? Still pretty accessible with a little lower back pain and you wouldn't have such a huge increase in the hose length. could always fab up a little heat shield under them as well to keep heat away.

 

The solenoids i have are to large to fit behind the uim. The lenght of the vacume hoses is minimal as far as i can tell. As sad as it is my system never worked with stock solenoids and the only other FD ive ridden in was non-sequential so i couldent really tell if their is a difference in lag.

 

Thats probably where im going to mount mine. The pics I posted were my buddies 7. In a few months ill pick up some solenoids and see what I can come up with. Maybe ACV and all the garbage on the firewall and all turbo solenoids where I have them mounted now. Might be pretty clean.

 

i'm so glad somebody dug up this old thread! i searched for it for about a month at one time, i have an original set that Rob made. they will be going on the car in the very near future!

subscribed so i don't loose it again and see if someone modifies the design

 

Firbirdgta I think you need to make a write up on your set up

 

Any one making these aftermarket solenoid kits yet? I am looking to buy a kit like Davids original kit or even an original used or new David solenoid kit.

 

bump for someone to make and resale these things. I dont have the time to do anything like this on my own.

 

+2
I dont have the time and I dont think I would have the know how.

 

+3

A simple kit would be amazing. Someone could make a rack with hoses and some simple instructions detailing where to hook each one.

Then we wouldn't all have to go through this mess one by one.

 

I think any of the top rx7 shoppes should do this

 

+4

Sooner or later a lot more of us are going to need something like this. It would be nice not to have to remove the UIM.

 

Dem I wish some one would come out with a kit some time soon. I need to replace some of my stock solenoids and I really dont want to go back to stock solenoids. I feel like it would be a waste of money.

 

This seems to sit in limbo because most people go from stock straight to single turbos.

BNR are the only folks I think that would profit from designing a system like this to work with their stage 3's.

 

I like this thread, would be so great just to buy a nice premade kit.

 

I have a set of the "originals" waiting for my BNRs . . .

 

Here are some pics of where mine was mounted before I went single this winter.



Clean, out of the way, and unobtrusive. The response was phenomenal and crisp, I loved it until I lost the corner of one of my apex seals.

 

Would these work?

I really want these..... im staying twins and eventually going BNR.

Someone really needs to refab these. Im willing to pay $150-200 for a complete set
