I do have the wiring in place. Two bullet connectors taped over in the harness back by the fuel pump. I think that requires the other harnesses and relays found in Carl's post of the Nissan document. Bottom line, the green cable isn't hot.

SteveJ, Questions about your comment. First, did Nissan use both of these sources at the same time? Isn't the solenoid only powered while the car is starting? Or is it powered all the time while it is running? My car still has the voltage regulator it came with. Well not the one it came with but stock...

He did. 'Adequate' to paraphrase. You don't have a problem if you aren't starving... I believe it was Leon who asked the question though. Maybe he could elaborate...

Here's an interesting tidbit... I just found out my Triple Webers are rare as hell! I have 42DCOE 8 triples. They apparently were commissioned by Maserati in the 1960's and were also used on Morgans and Triumph's... The reason I was researching them is I was thinking of selling them and going with 40DCOE 151's for the idle adjust-ability.

It occurs to me that Spec racing is an idea who's time has passed. "Let's make everything equal and then the best driver/team wins." Little room for innovation, and even that little bit of room gets squished by politics sometimes. I say, dial back the specs and see what they come up with. Give them room to create. Who knows? It might lead to hovercraft technology! 8)

A bit of the front end...

Another from Atlanta...

So, I bet you want to see what they look like finished right?

I quit entering car shows. It worked for me. But, I feel your pain. Arbitrary. The only 'class' I ever care about is People's Choice...

I saw the video of that 'punting' and I am not quite sure what happened. He didn't need to come down on the Deltawing. He had lots of straight to move into the line. If he wanted the inside in the next corner he would need to go around either in front by passing or behind, not through! But in the unedited version of the video I saw, that Deltawing is damn quick! One of the things I teach is critical thinking. I suppose you could say it is a form of the business adage 'thinking outside of the box'. It involves never accepting that something is as good as it can be. Accepting that the way things are done is as good as it can be, can exclude the possible along with the clearly not. The process is simply to develop a mindset that nothing is as good as it could be and then work to improve it. Once you have improved it, you start the process over. It's circular. I think racing could use a bunch of critical thinking. 8O

I also agree with Zedy, it appears prone to failure when contacted at speed... Gotta finish to take advantage of the time saved not in the pits.

Well, they brought more than one. These pictures were taken today at Petit LeMans... I do think a problem exists that the car solves. That being time in the pits for tire changes and fuel cost time on the race track. Time on the race track is what wins if you can run enough laps. This car runs about 3-4 times farther than most of the other LeMans entries on the same tires and fuel load. I find it an interesting study.

Mitchell, When you get tired of gazing out over those beautiful mountains in your backyard and you want to work in the garage, try that RX-7 pump. Quiet as can be. You can't even hear it with the key on and the engine off. Cheap too. Only $45 IIRC. On a Mikuni note, Keith Franck has really dove into the carbs Silverstreak dropped off. He has pointed out weaknesses, found where they tried to improve on the Weber design, and I think started to gather ideas to improve them. Silverstreak does about 90% track with his car, though he does drive it to events. If Keith comes up with some prototype e-tubes, Silverstreak will be testing them at Laguna Seca this Fall... Stay tuned. I will open a new thread on Mikuni improvements when that happens...

Still on a quest to wire the fuel pump into the factory harness. Sadly, I do not have the two relays and two harnesses depicted in Carl's attachment above. If you have a parts car - I need the following: RELAY A - 25235-P0100 RELAY B - 25230-89915 HARNESS A - 24032-N3300 HARNESS B - 24034-N3300

Someday this car will be vintage and I probably wont be around. I want to preserve it here so...

That's pretty cool! Usually when you find a 'rust free Z car' what they really mean is that the rust is free! Seriously, they need to get it running at the asking price. It should move under its own power so you can evaluate the engine and transmission. The interior is not insignificant but at least it is all available new still... I would put it closer to $1500

Any of you Mikuni guys who have been following this thread, Silverstreak (Bill) dropped off his Mikunis at Keith Franck's place today and his initial comment on Sidedraft-Central is that it appears that Mikuni just copied the Weber design on tubing and jets and such. What I take from that comment is that he believes he can improve them... Exciting news for you guys!

I would agree with everything Leon said but one thing... My Z is about 90% street use. If I could, I would reverse that number but alas, I still have a 15 year old at home so I have to keep working... Stephan, I suspect there is a market for your slightly used jets? I have some 50F9's in my box of used jets...

Here is one of the things I took from the discussion; Most problems in cars that run ok, are covered up by running the carbs rich. When you back off pig-rich, you may uncover some other problems you need to take care of. When you drive with these carbs on the street, you are likely running on your idle jets. Even possibly the highway. Leon got the tuning sequence according to Franck down in his post above. I think Leon's car came out better than mine yesterday because he has a rock-solid ignition system and mine is 40 years old but in good repair. His O2 readings were rock solid. I also think Leon wants to get his so close to perfect that he will be the guy to watch with his next moves... 8)

Oh I'm not concerned about catching Bill. That's just garage bullsh*t. He's a very good friend. Not my competition. 8)

Stephan, I already did. Go back a few pages and you will see my initial post in this thread. I called Peirce Manifold and did some changes and those are listed too.

Rainman, Keith is already commenting on Sidedraft-Central about getting ahold of some Mikunis from Bill and 3D mapping and designing solutions for them. I have mixed feelings on this as Bill is already too fast to catch. Not sure I want his car running better... :disappoin

Thanks for coming Leon. I will be switching to your ignition system as soon as you PM me with parts list and a starting timing map! 8P I can't wait!

Stephan, just back from the first Triple Trouble Carb Clinic. Big news for you, Keith will work with you until you get it right. You can just pay for shipping stuff back to exchange the Hypojets you don't need. Second bit of big news is he will be looking into making Hypojets for Mikunis. I can't believe the difference in my carbs! Not much difference in the top end, but wow do I have a crisp and quick responding bottom end and midrange! Highly recommend Hypojets!

What a great day! Glen, Patricia, Leon, Mark, Bill, Tim, myself and our carb expert Keith. My car ran good but now it is so much more responsive and crisp. The A:F ratio is in the 13:1 range at 70mph cruise. So very much better! If you have Webers I highly recommend Keith's Hypojets! If you have Mikunis don't fret, Bill offered to drop one of his off so Keith can develop Hypojets for them! And why not? Bill doesn't need his Mikunis! He goes through head gaskets as often as I do oil changes. 8O
