What a Rush

[The Horvaths]

Ah-ha ha ha ha ha!!!

Freaking hilarious!


I met at least one person who’s been calling the cops. After getting it tweaked a bit, I managed to fire it up again. It backfired a few times, but, I’m learning how to make it do my bidding.

Anyway, I shut it down and then went to check the mailbox. A lady was driving by really slowly. I waved and she rolled down the window and asked what’s that noise and where is it coming from?

Pregnant pause..


She continued: I don’t mean now. I don’t hear it now!


Oh, that’s a car. I’m tuning it and it sometimes backfires. I’m sorry that it upset you!

That’s a car? I live (pointing) not there.. across from there..


She lives a good way away by city standards. I’m so proud.


Son: do as I say, not as I do.

That's um, aggressive ...

If I were you're neighbor, I'd be at the curb drooling... holy hannah!

Sounds great.
Is that EFI in the ballpark yet for idle AFR?

Yep! It’s still been cold. Texas cold, anyway. I’m manually setting the Fuel/air map. I’ll let the computer go crunch on it in a while but for now, I’m getting better results (by far!) when I manually set fueling points.

Well, it’s not quite soup yet.
I fixed one more leak. The electric water pump has wet holes where the cap screws hold the water neck on. I put sealer on the threads. One step forward..

It’s probably putting too much fuel into the prime shot. I didn’t get it to start today. I pulled the plugs. They’re brand new. Honest. Two steps back.

I’m getting there slowly but it’s definitely not soup yet.

That is sounding good, now I want one too

Looks to me like you failed to give them a cleanup pass around the block...

That is a great sound with morning coffee.

 

[The Horvaths]

New plugs. Some changes to the initial settings. Got it started. Warmed it up to the point where it could start to learn.
One step forward!


By the time it got warm, battery voltage had fallen enough to cause the ECU to shut off.
Two steps back!!


I’m going to have to find some means of putting an alternator on it. The electric water pump and fan are causing some real pains. This may well be a never-ending story.

[The Horvaths]

Here’s the rub:
It does fairly well clear the crank trigger.

And the pulleys line up OK.

Belt just fits. Clears the frame.

What’s the problem?

Ahhhh...
..there’s a problem alright.

I’m going to build a pair of rigid plates. One will have two 3/8-16 clearance holes. It’s going to be placed in the front of the alternator ear and mount point. The other will have two 3/8-16 threaded holes. It’s going to be behind these points. Hardened bolts (cap screws, actually) will hold these two points together until the cows come home. I may also make a third brace to keep it all referenced to the block. Attention, mr. Alternator. It’s going to be my way- or the highway. I’m just not taking any prisoners anymore.

Now it’s raining. I had to bring in the battery charger. Mother Nature rules when you have to work outside.

Note: the crank trigger wiring is not shielded at the pickup. Instead, it’s just a twisted pair. However, the alternator is electrically noisy. This will pretty much mandate putting the pickup wiring inside a good electrical shield.

Fortunately, that’s my strong point.

Early morning musings:
From what I’ve read, and it’s been quite a bit lately, the AFR can be totally unpredictable if battery voltage is even moderately low. It’s probably the culprit behind the decent AFR readings yet black, wet plugs. I’m also of the opinion that the 18” header extensions are not sufficient for isolation from backflow-induced oxygen. So, we’ve got some work to do in those areas.
If they don’t clear up after the alternator is working, then, I’ll look at using a real Bosch O2 sensor and possibly a NAPA-sourced temperature sending unit. Why do I think that? Everyone’s favorite, Farcebook, has a group called “FiTech Owners Group.” It’s become one of the, possibly “the,” best sources of technical knowledge regarding FiTech systems. Several members there have had O2 sensor problems with the off-brand one that is supplied. As well, the temperature sending units are prone to offset and slope errors. Fortunately, they’re knock-offs of readily available equivalent name-brand sensors made in a world where effective quality control is embraced.

I was up quite late trying to get logs from the FiTech controller - only to find that it didn’t actually create log files when I asked it to. There may be something that I’ve done incorrectly. However, it’s supposed to be a simple push of the button. I did notice that the file structure of the new download that they sent me was missing some log storage folders. Sadly, the software typically doesn’t deal well with “exception handling” and also does not give an error message if it cannot perform tasks due to some readily-solved issue. If they sent a download that wasn’t fully tested, then I’ll suggest that I’m not the first one to get half-arsed technical “support” from FiTech.
Regarding FiTech’s support team: It’s their opinion that this is too much cam for their system anyway. It sure would have been nice to know that up front! In spite of that statement (they quite probably just don’t have the resources to take the time to explain what it takes to make it work), there’s a handful of people who have been able to make it work. I’m not giving up yet but it’s certainly a temptation!!!

Temptations are sometimes hard to deny.

Actually, as I read more and more (and more!) about the FiTech, I came upon this little gem. The EFI-8 1200HP unit has been flow tested by afficianados and found to flow around 835-850 CFM when normally aspirated. That’s plenty enough to spin up 493 cubic inches to about 5500 RPM. There’s just one little problem. This engine was designed for a shift point of 6500 to 6800 RPM. It’s just barely starting to breath well at 5500 RPM. As well, I’m just sick and tired of washing down the cylinder walls with fuel.

So..

Merry Christmas, son. We’re going to need a bit more plumbing and a much, much bigger-mouthed breather/filter. The FiTech will make an awesome pump gas setup for another vehicle. This massive beast is a 1050 CFM Holley three-stage dominator. It’s actually got a stage between idle and main jets. It’s a 4500 series, so, a proper manifold is a good thing. There’s a noticeable difference in the breathability and air speed of the 4150 and the 4500 series carbs. This manifold will work the 4500 just right.

HUGE BONUS!

We’re going to initially set the carb up using an AFR meter and the very high dollar Unleaded fuel. Then, we can switch over to leaded fuel at a third of the price! Yes! It’s much, much easier to find and comes in very high octane ratings. Once tuned nicely, we’ll plug the O2 port and the carb should only take minor tweaks from there.

Kiss any dreams of streetability goodbye. It’s now very much a purpose-built beastie. It’s going to be freaking amazing. I’m downright sure of it.

I guess like you said, one step forward, two steps back. That should be more than enough fuel and air.
