I own a 91 EA sedan 3.9 CFI
My parents own a 91 EB Wagon 4.0 MPFI

What is the reason for there car being a lot faster of the mark then mine.

MPFI? I know this makes a differene so we can rule that one out.
"But are there other factors" Read on please

The extra .1 of a Litre in Engine size?Ok does this help at all really?

Diff? Are they different in EA Sedans to EA Wagons.

Both cars are stock, both have duel fuel, both are Falcon GLi

P.S There car goes better then mine on Gas and Petrol

Thanks all

Shorter diff ratio in the EB and if the engine in their car is the 4.0MPI it will be 148kW vs the 120kW in yours. These two factors would be the main reason their car is quicker off the mark. Also take into account things like how many K's each car has travelled.

yeah the 4.0i has a better cam, MPFI will make a fairly big difference also..but yeah mostly the diff ratio i'd say..engine and trans condition can play a big part of it too

my mates EAII CFi used to be quicker than my Cfi even when he was running on LPG - my trans was stuffed, replaced it with a 3 speeder and now theyre about even

Yup, I'd put it down to the gear ratio & power. You should have a 2.77 diff, and the wagon can have anything up to a 3.27 diff.

Also, 28kW is a big difference.... not to mention the torque.

Thanks guys, yeah engine km not a worry they are about 2000kms apart.

My parents have about a year old rebuilt 4 speed gear box, im still on my cars original, which is not in the best shape as gear changes can be felt most of the time.

Didnt think of the better cam.

if memory serves me right, i believe the EA CFI motors produced the same as the MPFI... 133 KW's each...

was overseas for 8 years and my only link to ford australia was a EA catalogue with all the EA spec's that i held dear...

AUII_Forte · 02-06-2003, 16:28

The EA CFI was 120kW and the MPFI was 139kW.

Unless that is a replacement engine it's actually a 3.9

EB series 1's wern't all that different from an EA, it was the EB series 2 that was a huge step forward (when the 4.0 148kw engine was actually introduced, in mid 92).

well, it must be a typo... got the catalogue here... EA falcon...

CFI - 133KW
MPFI - 133KW

oh well...

My Mistake, my parents car is a 92. The side badges say 4.0i Twin Cam and its MPFI.

However its not new enough to have Smartlock
