This is the center console guage cluster. I'm going to have to make a new panel for it.

Right now I have the trick VDO oil pressure setup (with warning light as well) from the 914.

Coolant temp (although it doesnt' seem to be reading like it did on the bench (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) )

and Voltage.


I have a small fuel guage to go down there and a boost pressure guage as well.

This is the idle air control valve. It's a solenoid that can pull open and shut. The shut side has a resistor pack to ground, and the megasquirt controls the open side. The open and shut sides fight with each other to make a fully adjustable idle, and the MS will target a given RPM - so you enter that RPM with a laptop.

This is the MAT sensor. It's from a GM turbocharged car from the mid-80s. I didn't have the right connector, so I "did it right" and soldered the wires straight to the pins and filled the socket space with a glue gun to provide some strain relief (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

This nest is Bowlsby's worst nightmare (IMG:http://www.914world.com/bbs2/html/emoticons/lol2.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/lol2.gif) This is the megasquirt and the EDIS module and also the air filters. I used a small secondary filter for the idle air since it's tricky to route a 3/4" hose through a 1"radius turn for 90 degrees.

LOOKING GOOD!!! Well, that wiring could use some attention, but otherwise, congrats on getting it out of the garage under its own power!

Are you planning on going back to the dual turbo setup with this car at some point, or just keeping the single turbo?

I think I'm going to stay single turbo. The aftermarket for the single turbo is ripe, and even people that have had very good experiences with the twin turbo setup have still gone back to the single turbo setup.

If I get to a point where I need more power I might go to a ball bearing turbo or something, but there's plenty of options and plenty of things to do before I need to go that far (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

I'm just very relieved to see that I'm not the only (turbo) guy running intake parts that came from Home Depot. (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

Just kidding. Fiid, I'm very excited to see you making this progress. I was bumbed when I thought you had dumped the project. Keep posting - this is great stuff.

Thanks! I'm glad I stuck with it now - it's really keeping me awake at night thinking of driving it to work a couple of times a week.

LOL. ABS is cheap, and easy to put together, seals well, and you can screw anything into it. I pressure tested the fittings and got them to hold 30lbs (you have to do the clamps up REALLY tight), so they ought to be sufficient for 15lbs of turbo boost (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif).

All the ports (i.e. where that temp sensor is screwed in) were done by drilling a hole, making it the right size and then just screwing the right npt thread into it.

I realise it's not going to work forever: What do you guys recommend for a replacement strategy?

What are you expecting for inlet temps? I think that ABS starts to deform around 185F or something like that.

Good to know. I wouldn't expect the intake to get hotter than like 130-140 degrees, but I haven't done any math on that...

My datalog showed I hit 194 F for a few seconds one day last year. (No intercooler)

Well, I messed up the linkage on my wastegate around that time and it didn't have enough travel so the boost would creep if I stayed on it beyond 3rd gear. I hit 2.0 bar a couple of times before I figured out what was happening and fixed the wastegate linkage.

I logged 147 degrees this evening with only 6 lbs of boost. I see why air-to-air intercoolers work (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

I need to find a place that does turbo projects (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

Thanks for posting the pic of the idle air control solenoid, it reminded me that I should probably have that hooked up. Idles much better now! (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

Glad to see you project is on the road!

No pics this weekend - but lots of progress.

I have been fighting with the cooling system a little bit. It took me a long time to figure out why it would boil over every time. I was truly beginning to appreciate the simplicity of an aircooled engine when ..... I finally figured it out.

(IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

My coolant hose was within 1" of the header. The radiant heat from the header was boiling the coolant in the hose, before the engine was warmed up and the coolant was actually flowing to the radiator, so it would boil over before the fans kicked in or any radiator flow was happening at all.

This was cured by cable-tieing the hose back out of the way - which seems to work nicely.

(IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif)

Now on to the next problem - the engine seems to "miss" occasionally when I get up above 3k RPM. I'm thinking this could be caused by the EDIS wheel reading getting interference - or perhaps something more sinister.

I got some small taste of available power - and it was... NICE. I don't think I have more than half of what will be available post tuning and proper boost control, however.

I hope the engine runs better than it looks, 'cause it looks like an electrician's scrap bin in there!!!!! (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

Thanks! It's a bit of a mess, but I have made virtually no effort towards tidying it up. The circuits in play may change more so I'm just making sure there's sufficient room to move stuff around again if I need to.

I hope you aren't offended by my comment.. I don't mean anything by it. I am a bit obsessive when it comes to wiring, in both my professional life and my hobbies. My tools get scattered over the garage, my parts are all over the place, but wiring... well, I can't STAND a rats nest of wires. I have to straighten them out and make them neat and tidy. I am just weird that way........ (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)
