RE: [DML] Why Owners Carburete Their DeLoreans



Bill,

I believe a properly tuned carb won't kill the cat right away but it can
shorten the life of the cat... I'd personally like to see the data either
way.

But...

How would you ever know if the cats stop working? The carburated cars will
not pass smog anyway.  
I will also mention that the swap you do violates epa laws (ie it is not
legall).  I imagine that the cars you do this on are  in areas that do not
have emissions testing.... It's still not legal. Unless you have put your
conversion through CARB OE certification... 

Do you inform these people that there could be fines exceeding $10k?  

Do you realize the position you put your self in if you are reported to the
epa and they bother to investigate?

Richard

Farrar Hudkins -- the one who started the carburetion craze -- has been
running his carb with catalytic converters (he has two of them) since 2008.
John Marconi has been running his carb with a stock converter since 2009.
Bob Babcock has been running his carb with a stock converter since 2010. I
believe Garen Martens and Virgil Poole both have stock converters, but I
haven't seen their cars in person to verify that.

No, I am not worried.

You certainly are worried. Since both Farrar and John read the DML, why
don't you send them each an eMail message to that effect? They have been
running carb conversions the longest (#1 2008 and #2 2009), so your warning
is long overdue.

If I send send them an eMail, it will read something like "glad your carb is
still working well all these years later, especially in conjunction with
your exhaust system," which just won't have the same effect.

The problem you report exists only in your head (insofar as it is directly
connected to my conversions -- your problem is theoretical, not empirical).

Until then both of us are going to have to patiently wait.

to begin with, right? I'd put money on their cats being knackered before you
went anywhere near the car. I've seen what happens when a non-lambda k-jet
system is hooked up to a working stock catalyst so I'm talking from
experience as well as education.

tuning his carb. Allstate Carburetor (www.allcarbs.com) sells Motorcraft
jets in every size available (eBay jet sizes are hit & miss). Also, if any
owner wants to use a venturi size other than 1.08", Autolite castings have
many more size options than Motorcraft (bear in mind that Autolite 2100's
have twitchy choke pulloffs, and there isn't any easy way to put a
Motorcraft pulloff on an Autolite casting). Owners seem happy with the
castings and jets I provide, however subjective that happiness may in fact
be.

performance. You can call them delusional or liars if you want -- I'm just
happy that they are happy.

They wanted a bolt on, turn key replacement that would work reliably from
the first key turn onward. That is what I make. Arguments that these owners
should have designed and built their own induction systems (of whatever ilk)
probably ring hollow in their ears. That other owners have done so is
irrelevant -- people who come to me are looking for a complete conversion in
a single box, a "kit" if you will.
