Series 2A petrol Dyno figures

[bill.b]

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

Or 2.25 diesel!

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.

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 (https://www.uniquecarsandparts.com.au/car_info_land_rover_series_2a.php)

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

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 (http://www.expeditionlandrover.info/enginePwrSpecs.htm)

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...

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.

Just to further complicate the situation, the 2.25 petrol came with either 8:1 or 7:1 compression! I can't find what the difference in power is, but it will be in the single digits (hp).

I should probably provide a little more background. I have a 1964 SWB petrol car that I will be putting a 300TDI into with an r380 and series transfer case. Anyone that thinks it can not be done please save your breath.
I also have already converted my axles to Range Rover ones and have vacuum assisted disc brakes on all four wheels.

The aim of the game is to transfer the engine with evidence that the 300TDI has <20% power increase from the stock series 2.25L (74Hp).

This way I negate the need for any major changes necessary with a engine swap >20% increase of power (collapsible steering column, 2 speed wipers, demisters the list goes on)

There is no point going off the engine HP provided by Land Rover for the 300TDI as is over 20% power increase (111hp).

Therefore.......



In NSW if you want to be legitimate and get your car engineered you have two options.


1 - Chassis dyno your series to prove its HP and then chassis dyno the 300TDI and de tune it to the required HP. This is fine however you would be starting off on your back foot as the hp figure the series would give would be depressingly low.

2 - Engine dyno your 300tdi and "de-tune" it to spot on 20% power increase. This way you utilise the engine hp figures provided by land rover for the series to your advantage.


I am now about to lock in option 2 unless, I can find someone with a peppy S2A SWB CHASSIS dyno figure that is around the 74HP mark. TIf I had that I could chassis dyno the 300TDI and de - tune it while the engine is in the car which is much cheaper.



I hope this makes sense. The fact the 6 cylinder engine only came in the LWB model does not help my case.

Cheers,

Bill.

So, a red motor in a s2a chassis......?

[bill.b]

They were a dealer option I believe not a factory option.
