Speechless.

 

Its almost sad to see it come to an end. This was my favorite project to fallow. What will I ever look at while I'm at work now. :)

 

I agree with getting rid of the fan. I did and am glad I did. looks so much cleaner and I can actually work on the front my my engine. Cools a little better I think to.

This may seem like a small thing, but, are you going to vid so we can all here the trupets resound with throttle cracking?

Please,,,,,,could you remove the fan?

It might kill the experiece too much.

 

I imagine if i don't do a video I'll be hunted down like the dog I am.

 

Fans,fans, fans.... all this talk about electric fans. Now I'm looking at ebay for a Taurus fan.... And searching Hybridz to see if it will work.

 

I agree the distinctive woosh will take away from the throttle sound.

 

Do you have any use for my first born, because I don't. But I would give just about any thing for one of those manifolds. WOW! Just beutiful. Keep it up Derek!
Thanks Roger.

Not interested in trades at this time but you can probably get enough for him on the black market or ebay though!

I guess you'll have to switch back to porn!

I was thinking of the same thing earlier. As badly as I want this to be done I'm going to miss the design challenge.

 

Fortunately I've got lot's of other stuff lined up.

 

Hmm that valve cover is looking pretty plain.....

Hey Derek its looking amazing. Id have to say i would run your injector harness a little different also. You could hide it much better. I think i saw your relay board over by your battery in one of the pictures. You should try to run the harness under the manifold and back to the fire wall and into the hood latch brace and then to the relay board. Ive redone my injector harness this way since you've seen it and it looks so much cleaner. Obviously my relay board is under the drivers inspection lid but you get the idea. I really think you will like the look of it with out those wires there.

Thanks Jeff.

The issue isn't so much the injector harness as it is the vacuum lines for the vacuum log. They have to go across to the log that has yet to mounted on the fender well. Since I have those going across I might as well have the injector harness there as well. This routing tends to get everything out away from the heat faster than going to the fire wall. I made the harness long enough to go either way so I can still change it. In person it really doesn't look that obtrusive.

I noticed something in one of the photos. You have what looks like carpet padding covering the dizzy hole. Now I saw your coilpack, so no need for a dizzy, but what is that material? Is it temporary?

 

 

DING DING DING we have a winner!

 

I was surprised no one said anything! It's a piece of terrazo colored corian solid surface material. I use it a lot for my prototyping. I wouldnt use it as a permanent solution but it's held up well for a few hundred miles! Keep your eyes pealed and you may see another piece as a fuel pump blockoff in the near future!

 

Too bad there isnt a prize though.

I see you are monitoring all 6 egt's, but how are you going to use that information for anything other than diagnostics if you are using megasquirt?

 

You're going to have to step up to something a bit more powerful to do individual injector trimming, if you need to.

Wow, Derek, thats really getting sexy... The Alodine finish really looks good. I have no idea why I ever suggested billet for the Thermo housing. it looks awesome just cleaned up. very very nice.

 

So, didn't we have a good discussion on head shields about 14 pages back? I seem to remember us all talking about something there. Better to put something in before you get to the "what's that smell?" phase.

 

I really like how you drilled and ran your injector leads underneath. That must have taken some time. What heat resistant sheathing are you using on those wires? A melted wire could be bad if it's a ground, since both MS and bosch use grounds to complete the injector circuit, if one melts, you could end up w/ an injector stuck in an on state = very rich and flooding. your upward tilt (4deg?) should push that flow into the engine, but I don't think it would be a good situation. I know I didn't have to mention this, I'm just backing up my vote for a heat shield. :wink:

 

still looks pretty amazing... uh don't forget to reinstall those rocker cover bolts. Oh and what's is that bottom bung on the horn of #6 for?

 

You're going elect fan? Let me know what you find, I'm probably going with an electric fan on my S30 too.

Derek, I've been lurking on this thread and like others, think the work you've done is really fantastic. For a NA motor the stock intake manifold is a limiting factor for power and so I'm thrilled to see you breaking new ground here.

 

On the electric fan issue, I see from one of your pictures that you still have AC. Assuming you're going to keep the compressor, I think you'll find that the Taurus fan's motor interferes with the compressor pulley, at least it did with my setup which includes the MSA 4 core radiator. There just isn't enough clearance between the engine and radiator.

 

In the end I took a different approach using 2 12" slimline ebay fans. After having the radiator begin to leak from the cable tie mounting approach through the fins, I switched over to this approach. I don't want to hijack this thread but I'll throw it out there as an idea to you hoping (expecting) that you'll come up with a more cleaver, or at least better looking, approach.

Hi olie

I'm only using them for analysis. Since this is a prototype I want to be able to see how even they are.

Hi Phar

Yes we did have a nice discussion on heat sheilds and I promptly discarded it as soon as I had the header on the mock up head. Here's the deal. I really want to design something that's as unobtrusive as possible. I really like the look of the headers through the manifold. In order to do this I have to run it so I can see what I'm dealing with thermally.

I have a insulation blanket that I'll be putting under the web to protect the wires and vacuum tubes. Hopefully this will be all I need.

 

The bung on 6 is the air temp sensor. That may get moved outside the manifold depending on how bad the heat soak is.

Well I guess I'll stop looking for a taurus fan! Was it the shroud that hit compressor or the fan?

It will be a while before I do anything as I'm going to be burned out and a lot poorer by the time this is done!

Actually, it was the back of the fan's motor that interfered with the compressor belt's adjusting pulley IIRC.

 

My compressor doesn't use an idler pulley as an adjuster.

Do you think I would be able to make it work with this.

 

Thanks

Side note, (I don't want this to keep going off subject here, but)

Don't run ac utill you have a way to run the fans manuelly.

I've blowen two because I forgot the condensor needs to be cooled at idel even when engine is cool. Takes about 5 mins, in cold, from a dead start up, for the system to purge it's self.

Quite the sight.

Well I'm starting to see the end of the line.

4 speed to 5 speed swap complete.

Header installed

Intake installed.

Fuel delivery line converted to 6AN.

Injectors installed.

Fuel rail installed.

Fuel system pressure tested at 125 PSI.

All sensors connected and operational

(this is starting to sound like a freeking countdown)

 

All I have left to do is install the surge tank and hook up the pressure regulator and then fire it up.

 

Tomorrow should be the day.

I'll bring the video camera in with me just in case.

 

Derek
