It only seems like we were talking about piston options for this a couple of months ago.

Looks to be coming along nicely. Go the alloy big block!! Haha

Thanks mate. I'm impatient now. :D

[LittleRedSpirit]

Dave Ill measure the size of our setup tomorrow for you.

 

I think it was only 150 wide, and with the suby filter being 165 it might make things a bit tight.

[LittleRedSpirit]

 

I don't think we need anything more than thte correct size opening in the box and the lid from a filter box that suits to make it work nicely. A filter is just rectangular, rubber and has a step in the rubber to locate it, so I think we can just bypass the hassle of mounting the lower edge from the box to ours.

[ke70dave]

Hmm yeah 165 is too big, wasnt sure how wide we made it.

 

I think you might be right with the filter, just drop it into a hole in the box. makes it easy to make too, just need to make sure that our clipping method is reliable.

[LittleRedSpirit]

Thats right, I guess it would be best if all the clips were either on the box or on the lid, so we either just have to mount the clips or make small retainer edges for them to catch onto. Adding a vaccum port ar at least a couple of threaded bosses for different sized nipples would be good. I think we need one 10mm one to feed idle control, maybe bigger, and something to give a map signal. Wondering if I should tune this car on an afm or whether I should stick with MAP, I don't know anything much about afms, different types, and their use in tuning as much as TPS vs MAP tuning like I was running.

Stole this from the custom search on the K and N site. Searched for filters 300-375mm x 130-150mm. Plenty of suspects for the wreckers hunt there, just need something with a large intake hose that points a useful direction, and a good clip system.

Seeing as you've got ITB's on TPS/MAP tuning down, I'd stick with that.

The majority of AFM's can be a fair restriction anyway. I back to back tested this with the FJ20 datto, when I got it running on the sprint 500. First run @ 19psi made 185rwkw(with the AFM plumbed but not using for tuning) then ditched it and power went to 215rwkw and everything happens 1,500-2,000rpm earlier.

It certainly wouldn't be the case for all AFM's, people seem to get good results with Z32 ones.

 

[LittleRedSpirit]

Been googling the cars in the list above to see whats worth using. Jeep wrangler lid looks pretty good. A fairly large inlet pipe. Plus it will point towards where the air is being brought in, under the radiator.

[LittleRedSpirit]

Have been looking at the neatest way to operate the heater. I reckon Ive got it sussed. The Monaro type heater tap is vacuum operated, so i think Ill use this just hooked up to a fuel vapour purge solenoid. Then it will be electrically controllable and not mechanical, and means I can put it anywhere the heater hoses, vac line and wiring can reach. I didnt like the cable coming through the firewall, so this will give me bunch more options.

 

[LittleRedSpirit]

Bit of a dead end on the vacuum valve for the heater, its always open unless vacuum is applied to close it, so it will work reverse to what I need. Had a look and found one that would work, but its 19mm nipples, and not 16. Its a 3 connection bypas style one, so I would need a T piece also but thats no big deal. Anyone know of any car with one thats closed until vacuum is applied? I could cut up the other type and make it actuate backwards but its a lot of work on a $30 part.

[Medicine_Man]

can you just use a vacuum switching valve to control if it gets vacuum or not?

[LittleRedSpirit]

I think the problem will be as you rev the engine vacuum disappears and you end up pumping spurts through the heater as the vacuum needs to be constant to keep it closed. If vacuum opened it, then you could use it fine with a purge solenid to control it, but it works the other way around. I could still modify the part by flipping the actuator around, as I can't find any part thats going to do what I want so far.

[Bowler]

Could you possibly run it with a one-way valve to hold vacuum, then bypass through the purge solenoid via a couple of tees?

[LittleRedSpirit]

Thats not a bad idea. I was trying to work out how to do it in my head with a one way valve.

 

I guess if you have a one way valve, then a t piece connected to a purge solenoid to open the line after the valve from the tee, you can maintain vacuum and then release it electronically, allowing the heater to work. The only question becomes, the open line is a vacuum leak, and will make the car run a few rpm faster, so I need to be able to source clean filtered air that goes through it from some source that is filtered but not under vacuum, and that doesnt lift rpms.

 

Maybe if there are 2 purge solenoids, one on and one off at the same time, so normally the line to the vac tap is open and via a one way valve, with the t piece as described, and there is a solenoid to open or close the t piece, which lets the vacuum tap have air and thus lose vacuum. To stop the motor sucking this air, maybe we need another solenoid to close the line at the same time to the engine, so it cannot apply vacuum to the open air and suck air in. Maybe I can just use a purge solenoid that isnt a simple open and close of a line, but it bypasses through its own little filter cap when it needs to drop vacuum to the tap. Then I just need one, and when its off (open) vacuum is applied to the tap and when it bypasses it will close the line that normally allows vacuum and give atmospheric pressure through to the tap, while blocking off the line to the engine natively.

 

As long as those small one way valves you get in the small vacuum line are adequate to hold enough vacuum to keep the heater closed, then this should work. I wonder if unsing a 3 nipple bypass type heater vac tap will stop excessive pressure forcing open the valve and overpowering the vacuum, since it can just flow anyhow. Then I need a T piece in my heater return to allow either line to flow back in, but thats easy. Its a few more hoses than I was hoping for, but I can hide most of this under the airbox I think.

 

Cheers Bowler.
