Lotus Elan

Hello from a new member

PostPost by: PaulRB » Wed Mar 18, 2015 9:16 am

Hello All
I have just acquired a 1967 Lotus Elan +2 That has been set up for tarmac rallying. I have had to make a few changes to it to allow me to get use to it. First was to fit a normal car battery as the lithium one abut the size of a good match box does not allow for someone not familiar with starting a twin cam engine. Second was to fit some road legal tyres It had Dunlop 185/70 R13 85H Radial PG710 SP Sport D53J stamped for competition only I have now fitted Avon 185/70 R13 CR6ZZ the next thing I am considering is to change the diff at the moment it is a 4.4:1 the acceleration is good its fast off the line but its doing 4000RPM at 65MPH. More to follow as I find out about it.Image Image

That diff will be very sale-able (if that's a word) to the racing/sprinting/hill-climb boys.
My advice would be to go for a 3.55/3.54 for relaxed road cruising; I've got a full set of diffs and that's my fave ratio for general road use. :D

Welcome Paul,
If you are wanting to use your car for road use, then as Pete says the diff will be better as a standard 3.77 or 3.55. Standard Elans are not known for being traffic light racers, but your current set up will frighten quite a few exotic cars in the 0 -40 mph race.
Your air filter will be better sited in the nose cone to gain colder air, other than that what a nice car to enter Elan ownership!
Kindest regards

Hi and welcome, Paul

Looks like a clean car from here. Straight cut boxes can be a tad noisy.

As you have discovered, 4.4 is good for acceleration but bad for the nerves. The 3.55 diff is good for touring or in tandem with a modified engine designed for more torque.

Common options are 4.4, 4.125, 3.89, 3.77 and 3.55. As stated above, the standard 3.77, or perhaps the 3.9, are good choices for spirited driving. Series 1,2 and early 3 were originally fitted with the 3.89, later series 3 onwards were fitted with the 3.77 as standard with the 3.55 as an option.

Once you get the hang of getting the diff out, having a selection can be useful so don't sell the 4.44 straightaway :-)
