Hi. New here. Found this site in search of info on my SCoT supercharger. Planning to fit it to a Rover straight six 2.6 liter, side exhaust top inlet. 7.5 to 1 compression ratio. Any technical advice as in efficiency, flow rates etc would be of interest. Also have a friend building a land-speed record vehicle with a Cleveland(?) Ford V8. It is like a modern version of Burt Monroe and "the world's fastest Indian" If anyone is in interest of that, let me know. Looking forward to lots of learning, and Hi to all from Johannesburg!
The Rover 6 was never a good engine. Top end oil issues. Not worth using it if you can find a Rover V8. There are no speed parts or anything I have ever seen. Welcome to the Hamb Singlefingerspeedshop.com. Detroit
I disgree with captain scarlet. I love the Rover IOE. A beautifully built engine with roller rockers, a lovely sound and 100hp from 2.6 liters. I often drove 100mph in mine. The Rover P4, the main user of the IOE, was one of the finest motor cars of the day. Read the "Car and Driver" review of the Rover 100 around 1957. They claimed it was the finest touring car in the world, period. Loads of low down torque. I remember teaching my little sister to drive in my 1963 Rover 95. We were practising a hill start. She pulled off in 3rd instead of 1st and never even noticed. Then changed to 4th almost immediately. It's a lovely engine, and one day I'll have another. For speed parts use the Westlake head for a 25hp increase. The IOE was also available as a 3 liter in the P5. It was installed in Land Rovers up til 1980. Back in the day, Rover didn't build cars with "issues". Ed
The Rover engine is typical old Rover. It is almost indestructible, very tolerant of bad petrol, it uses about 0.5 liters of oil per 1000 km and it idles almost perfectly. As you say it has torque right from idle, but it does not like revs much. Mine is indeed a P4, and I have one with a Weslake head, and a couple of others with the normal versions, two with 2, and one with one carb. It is right, however, that there are some issues with upper lubrication of the camshaft. When Rover got the Buick engine from GM, they worried about the camshaft wear in particular, and the Americans couldn't understand the fuss, stating it would last at least 150000miles. The Rover guys worried in any case, as if they expected the engine to last forever, much the way they themselves built things, in those days. I thought of the supercharger, because I have it, and also because it fits nicely with the period, and particularly, because there are not many, if any, speed bits. The low compression and the supercharger should go well together, and the knock resistance of the engine, I thought, might make this an ideal combination, for the engine itself is normally indestructible, if you watch the revs. However, some people race these things, I have been told, so maybe there are some options, I don't know. However bolting a supercharger on the unit would be simple and not require any other speed parts and should give you about 160hp, I guess, which of course in the scheme of things is not much, but in the P4, in particular, should give a useful boost in capabilities. so I might still try.
Sorry I was thinking SD1 six. P4 - took a look through the P5 books I have (think still the same engine) and all I can find for the rally cars were head and carb changes. Did find this though...... http://roverp4guildaustralia.wordpr...uld-a-rover-p4-look-as-a-historic-racing-car/ Good luck Martyn Singlefingerspeedshop.com. Detroit
And let's not forget, a Rover P4 set the world speed record for jet turbine powered cars in 1952 at 152mph.
