2 solenoids+2 g-valves+1 switch = 3 stage boost contoller

[A.J.]

First let me explain my set up. 88' Caravan, 2.5, auto trans, T-II Garret with a .48 housing, Toyota Supra intercooler, and '89 stock electronics.

I had 1 grainger valve set to 12 p.s.i. for the summer and 15 p.s.i. in the winter because I was getting to much detonation in the summer. I would barely get on the gas and I'd be at 12 p.s.i. and driving in the city in traffic there's no need for that. Plus when I use the cruise control when I hit a hill the boost spikes and the lower boost setting would help fix that. I was just going to have one g valve, low and high boost setting but I don't want to have to readjust the g valve for summer and winter. So I have three settings: Low 7 p.s.i. (no g valve just the spring in the wastegate), Middle 12 p.s.i., and high 15 p.s.i. I'm trying to figure out how to mount the switch to the gear shifter. When I figure it out I'll post an update.

The way it works. On low, the non-energized solenoid on the left lets boost to the w.g. On middle, the left solenoid becomes energized and shuts off flow to the w.g. and the non energized solenoid on the right lets boost to the w.g. On high, the left solenoid stays energized, the right one becomes energized and lets boost through the right solenoid 3rd port and the other g valve to the w.g.

Looks pretty good. I always like it when guys make stuff like that and post the pics. Thanks for taking the time to do so.

I have been thinking of doing something very similar with my unused purge sol's..

I mounted the switch on the shifter today. I did the best I could with the size of the switch. I don't think it looks bad but I could not think of a better "cleaner" way to do it. The position is awesome. I don't have to lean forward looking for the switch. If I need more boost in a pinch, it's easily accessible and I don't have to take my eyes off the road. If those who read this don't mind, could you please give me your opinion on how it looks. If it looks crappy, okay, redneck, awesome, or whatever.

10/10 on a pragmatist scale. Nice work.

[Darkapollo]

not too bad.. though i would do some searching for a column shifter with a button for that 'stock' look..

looks amazing. redneck amazing but amazing none the less. only thing... take some ABS plastic and glue up a cover for the rear terminals and bolts. make it slope from the terminals down to the bolts for a lower profile.

super cool.

I found a smaller switch. I had to solder the wires on. It's a 6 amp switch compared to the 20 amp that I used first.

I like how the lever on this one is red. Much cooler.

Yeah, all that thing needs now is an XD 40 cal under the seat in a safe box

[A.J.]

Ya I thought of that already. But I prefer a compact 1911 in .45. Did you see my pictures in another post?

I thought that was an XD handgrip I don't have one, only fired a friends and still lust after it a bit. It made my Glock feel like a dinosaur

Alan, how could you confuse the grip safety on a 1911 for an XD.

I thought it was to much of a coincidence that you mentioned a safe under the seat after I posted my pics.

The XD is all black with a polymer frame. The 1911 is an aluminum frame.

XD 40

back on topic...
I'm gonna do a 3 way boost controller when I get my car running again. I think the switch looks tacky as hell, but it works! I think you should look at a WOT switch. that way you can have 7 psi around town, but as soon as you go WOT you can have 12 or 15 depending on where the switch is at

[A.J.]

Thanks for posting the pic of the XD.

Very rarely to I go to w.o.t. So that option won't work for me.

not too bad.. though i would do some searching for a column shifter with a button for that 'stock' look..

I tried this but couldn't find anything. But I only searched for about 1/2 an hour. If anybody finds anything with a switch mounted in the column shifter please post it here. With my wiring and a stock looking switch, that would be a sweet set up. Just keep in mind you need a 3-way switch for a 3-stage boost controller.

you should unless the cal has been modified. stock cals have less fuel and more timing at non wot than at wot. if you reach the limits of the timing retard upon knock, youll have toasted parts.

City boy I'm afraid 'Round these parts we don't get much opportunity to snuggle up in a bathtub with an assault rifle Brian I go to the range (indoor no less) like twice a year

I hear you there. When I lived in the big city I didn't have time nor the energy to drive far enough to shoot often enough. Now that I live in a rural area ammo is ridiculously priced.

That's why I don't, and that's why a w.o.t. switch won't work for me. I'll keep my "redneck amazing," "tacky" switch until I can find something "cleaner."
