    Series 2A petrol Dyno figures

    Hi All,

    Does anyone on here have a dyno sheet of their Series 2A they would be willing to post?
    I need proof of a good wheel horsepower figure for an engineer.

    Cheers,

    Bill

    Sorry, can't help you there.

    But I am going to watch this thread with interest. I've never even conceptualised the words "Series IIA" and "Dyno" ever being linked...

    Hello Bill,

    I do not have dyno figures.

    However, for those who may have the information; you will need to clarify what capacity petrol motor your 2A has.

    Is it:

    • a four cylinder petrol 2.25 litre, or
    • a six cylinder 2.6 litre petrol motor?


    Kind regards
    Lionel

    Yes sorry, I was after figures for a 2.25L 4 cylinder petrol engine.

    Did the 2A come with a 2.6L petrol motor? What was the quoted power output for this? I thought this was only offered in the S3?

    Do you have any reading material on this.

    Much appreciated.

    Bill

    Hello Bill,

    In 1967 the Long Wheel Base - 109 came with an option of either the four cylinder 2.25 litre petrol, the 2.25 litre diesel; or the 2.6 litre six cylinder petrol motor.

    The Short Wheel Base 88 inch chassis only came with a choice between 2.25 litre petrol or the 2.2.5 litre diesel

    This link provides a brief snapshot of the six cylinder engine - accessed 3rd March 2020 from, Land Rover Series 2A 2.6 Litre

    Country: United Kingdom
    Engine: 6L Petrol
    Capacity: 2,625 c.c.
    Power: 90 b.h.p. at 4,500 r.p.m
    Transmission: 4 speed. manual

    However, the Ho Har's did have a SWB Series 3 that someone had previously fitted a six cylinder 2.6 litre motor to.

    Kind regards
    Lionel

    Hello Bill,

    I just found this link that describes some engine specifications... Accessed 3rd March 2020 from, Power specs for engines commonly used in Series Land Rover engine conversion

    Please consider that the author - TeriAnn Wakeman (2017), states that: These numbers were taken from multiple sources and I do not testify to their accuracy. I do think that they are interesting though...

    I hope it is of some help?

    Kind regards
    Lionel

    I'd think the 90b.h.p. quoted is at the flywheel. The figure at the wheels will be substantially less, and my guess this is the number the OP is after.

    Hello Aussearcher,

    I have to go back and agree with Johno1969's quote about dynos and Series IIA...

    Kind regards

    Hello All,

    I am not an engineer - anyway...

    If looking at horsepower at the wheels these two sites combined may allow the at the wheel figure to be calculated from the crank data.

    All sites accessed 3rd March 2020

    Horse power
    Engine https://www.automobile-catalog.com/c..._25-litre.html

    To calculate wheel Wheel Horsepower to Crankshaft Horsepower Guestimator

    If you are after engine torque to wheel torque there is this site ....How to calculate wheel torque from engine torque – x-engineer.org

    Well back to the job applications.... weee

    Kind regards
    Lionel
