Fidanza Aluminum Flywheels

With EFI, an electronic iggy and a nice linear advance th' thing is likely to raise eyebrows precisely 'cause it's burnin' TOO CLEAN for a '76 MGB: "Step out of the car, Sir, and come with us."

It actually sounds quite "do-able". I'll be interested to learn how it goes too.
 
well... "too clean" may well be a good thing, seeing as how the MGB TBI kit is supposed to be approved by CARB... If I'm not mistaken, Bret is planning on attempting to add a wide band O2 sensor to the system too.

Ya know, worse comes to worse, you'll end up talking to a state emissions ref... but if yer emissions are good, then I reckon it'd all be worth it considering the potential gains you'll have.
 
Originally I’d planed on putting an O2 sensor. Wanted to position it in between the manifold & the Magnaflow “free flowing” Cat. But because according to Moss the EFI is a “black box” it doesn’t have any real adjustments. A requirement to get the CARB certification. To get around the added cost of adding a O2 sensor, Moss is going to monitor several things on the intake side - volume, CFM & Manifold temp (I think) & automatically adjust accordingly.

But I still plan on installing the Magnaflow cat so there will be s slight down pipe between the manifold & the cat just in case I decide to add one at some point in the future. /ubbthreads/images/graemlins/smirk.gif (wink, wink/nudge, nudge) /ubbthreads/images/graemlins/wink.gif
 
I'm not sure but I do't think I could put up with that kind of a check. Not sure I think it is any of their business if I have modified the engine or not.

Durn bunch of politions, always after you for something.

Understand the requirement on new stuff but these are our toys, go away.
 
Bret, you're proving to be a Genuinely Clever Fellow... This is a Well Formed Plan IMHO. Is there any news RE: CARB cert for the setup?

Photos of the process are expected, BTW.
 
hmmm... according to Moss the kit has already been CARB approved, IIRC.

***EDIT: to quote Moss's website: "Bolt on Electronic Fuel Injection Kit replaces the problematic Zenith Stromberg carburetor on 1975-80 MGBs. California Air Resource Board approved for 1975-79 MGB."

So I reckon the CARB approval only applies to those model years. However, it's only the '76 and later cars that have to under go smog testing... go figure.

Ya know, I hate conspiracy theories, but the coincidence of this kit coming out for those MGBs utilizing ZS carbs, and the changing of Cali law to lock down testing to those same year cars has not gone unnoticed by me.... :/ yeah yeah.. I know there are more 76 and up cars on the road than just MGBs...
 
Bret,

Is there a purpose built Magnaflow cat for the MGB? If not, you can get a generic Magnaflow with an O2 bung built in. It probably comes with a plug, but if not, you can pick one up at your local muffler shop for a buck or two. This will be a lot easier than pulling the thing and having a bung welded in after the fact.

I have an Innovate Motorsports LC-1 wideband O2 connected to my Midget, and it is neato! And not too pricey either.

BTW, even if the Moss ECU is sealed, there may be a few dirty little tricks you can play to lean or enrichen your mix. ie. an andustable fuel pressure regulator, a pot wired inline to the MAP or MAF sensor (whichever the Moss system uses).

If an aftermarket item for a vehicle requiring emissions testing gets the coveted CARB certification. Normally the manufacture of that item gives you a sticker with the CARB number, to affix to the platform shroud where the bonnet lock is with your other factory data (timing, idle speed, CO% etc.) emissions stickers are.

If you’ve ever bolted one of those K&N FIPKs to a modern car most have been CARB certified and come with a sticker stating so. This avoids any embarrassing situations & hassles, by telling the smog technician that what you’ve got is legal.

BTW Doc, had the Moss EFI kit not been already CARB certified I probably would have gone a different direction.

I did a lot of searching and no Magnaflow doesn’t make a cat for our MGBs. But on there web site I found was is called a “pre-cat” that is normally a lot smaller than a regular cat and normally works with a regular normal cat somewhere down stream. The idea being to allow designers to make better use of the engine compartment and get away from those space robbing manifold cats that you see bolted on both sides of your V6’s & V8’s. The one I want has a 2” inlet & 2” outlet, is about 10” long and it’s body is 3” in diameter. So it should breath a lot better and should tuck neatly just about anyplace. But for my application I plan o placing it in pretty much the same location the old cat sits with room for a “bung & a plug” just before it.

FYI I checked the numbers and this cat alone will work with engines over 3.0L by itself as a stand alone unit.

My plan would be to acquire the cat & a new 2” exhaust put in by a local muffler shop.

I’ve priced these too. If I get one that would probably be unit I get too.

Whow! /ubbthreads/images/graemlins/eek.gif Theres Bret standing there with his eyes rolled back in his head and his fingers in his ears saying: “La la la la! La la la la la! La, la, la, la! SORRY I CAN”T HEAR YOU!?! Did you say something about circumventing the emissions equipment?” /ubbthreads/images/graemlins/smirk.gif
 
Not circumventing... augmenting. Since the Moss EFI has no O2 sensor, it has no way to check itself and adjust the mixture. Also, it is designed to run on a broad range of engines in a broad range of tune. On a lot of cars, it will probably run a bit rich. On your car, with its many intelligent improvements, it could end up running a bit lean. If it is running lean the combustion temps are going to go up. High combustion temps mean high NOX output.

Kalifornia hates NOX.

Why, you would be doing Kalifornia a real favor by ensuring that your car is running at optimal mixture!

Of course, all this is pure speculation based on a bunch of infor I put together from the backs of sugar packets.

ps. This probably goes without saying, but if you know the Magnaflow part number you want, check eBay before buying from a dealer. I recently went through the long ardous process of finding a universal cat for my Midget, and I found the best deals (by a long shot) on eBay.
 
I'm a bit late in this thread, but as another option, you can try this too. I have a Txxxxxx and I nearly died when I compared this to the $529 from Moss:

And for anyone else, if carb certification isn't an issue and home tuning is, you might want to have a little look here. Has to be batch fire, but if you are doing TBI it won't be a problem...

One other option would be to try this if you have ZS carbs:

This would be a good retaliation for the back yard, "honey-dear" project. /ubbthreads/images/graemlins/cheers.gif

Holly COW! /ubbthreads/images/graemlins/eek.gif Hey, even I have my limits & @ $995 a pop as cool as those rods might be, I think can aford to pass those by and won't lose any sleep over it.
 
I hope for that price they are also cryogenically tempered... /ubbthreads/images/graemlins/jester.gif
 
and can sing a lullaby!
 
PAECO has them for $690.00 ea.
Not that I would ever seriously consider them.
 
Bret,

Sounds like you are doing some VERY cool things and wanting to play by the rules of the land of fruit and nuts. I will watch your progess closely and with much interest!

But back to the original topic, the aluminum flywheel. I would just be concerned about it's use for an everyday street car. Yes, by reducing the weght one can get a few more ponies, but I think at the expense of driveability. I don't have one as I don't race my car, so therefore I can't give you firsthand advice, only what I've heard and read. To that end the lightened flywheel is used to make the car rev quicker, which is what racers want as the real HP is produced at higher RPM's. The don't have to worry about sitting at stop lights and stop and go traffic. My concern is if you go with a flywheel that light, to take off from a stop you are really going to have to rev your car or it will stall, which I would imagine would get old after awhile. Talk to Paul S on the MGBexperience. He has an aluminum flywheel and said it really took ALOT to get used to and certainly wasn't for everyone. Maybe you should consider just lightening the one you have...
