Maybe, but its no good adding a load more fuel if theres not enough air to
burn it. Are you suggesting US Digifants run ridiculously weak? I thought
their poor performance was cats, weight, power this, power that and obvious
emissions compromise (but we have emissions testing every year too at MOT
time).
On the other hand, my DJ 2.1 WBX has just returned 15 mpg, and its not
really loaded up! (expect somedinks wong wivit - I mean I hope somethings
wromng with it, PO said 25mpg).

Shall get the emissions tested regardless and let you know before I start
looking for a fix (like LPG  :-)

Fellow vanagon types
The Eurocars people can't back up there claim of 115 hp. This is hollywood
horse power
I have been building engines for a long time and there story just does not
add up. The increase
of compression adds 4 percent to the engine per point of compression. and
the very small increase in displacement is not going to make any Big jumps
in
power.
     It sounds like the way they are inceasing the stroke is to offset grind
the rod journals and use a 30 under rod bearing. The higher compression
Ratio of 10 to 1 requires 98 octane to prevent preignition and engine damage
and this could cost power not make more so dont try this at home folks. so
these claims just don't hold water and I am the last one to knock anybody

]The European 2.1 10 to 1 engine had Digijet and that injection did have a

I have this past weekend tested a European 10 to 1 Digijet chip on a
chassis dyno this added 20% power to my 84 van with 2.1 big valve engine
that was I must admit was out of tune and sligthy down on power overall for
this test. I think this chip is everything the phony balony ozzie chip
wishes it was (lots more fuel). some of you may remember that I dyno tested
the ozzy chip and the engine lost 4 hp and the air fuel ratio was way to
lean.
     Ken wilfy and I are looking into more copys of the digijet chip and we
will be offering them soon.
    The camshaft I use in my big valve rebuilds is a minor reprofiled
reground from a stock 2.1 cam and with no cat it will easily pass smog Co
1.67 Hc 141 at a hot idle. The main problem with going to a non stock cam is
when you have allot more duration this disrupts the vacuum signal and you
can't have that with fuel injection systems and still have driveabilty. I
don't think eurocars is using a big cam to make power
It is easy to make claims of huge horse power and not so easy to back it up
thats the real deal
