Where to buy used Rover/MG engine in UK

I think it's the unpredictability / non linearity of the power delivery. The tendency for the power to surge as the turbo spins up without direct input from the driver. A normally aspirated engine, even a big one like an R500, gives you what you ask for immediately. And if you want a bit more you then ask for a bit more. Put your foot down in a turbo and you get something, then it keeps building, often quite suddenly. Mid way through a bend on the limit in something light weight a big surprise present from the turbocharger could spell trouble.

Exactly what I think. I had someone chasing me to help him registering a Cateham with an YB engine here in Denmark. I refused and demonstrated to him what happens with my own 200BHP car when it comes "on cam" in a corner in 2nd and full welly: It spins. You can handle the car when you know exactly when it happens, if you don't, you can't.

 

If I was to charge a Caterham in any way it'd be with a Rotrex supercharger.

 

But remember that only the half dead needs a respirator...

it all depends on the size of the turbo and the boost used, i drove a 1.4 K series turbo and it was very linear but i have to say it didn't made huge horsepower ( my guess was about 160 bhp ) In the wrong hands any Caterham could be lethal

I looked at pressure charging the 21 race car last year. Packaging, heat management, and weight were the major issues. Whether a turbo or charger you will need to intercool . The main advantage with pressure charging  was the area under the curve - torque which would provide more grunt down the straight bits with a loss of drivability through the corners, good when running in a power to weight class. You will need to Apollo or dry sump the engine to gain oil capacity / cooling. 15kgs + to the front axle and look at the final drive ratio in relation to the power characteristics.

I think there is a Rotrex kit available for the K series as fitted to the Elise. You would need to to some re- engineering of the pulley work and brackets to fit in a 7. I briefly looked  at a kit to fit my 1.4 K series wet liner engine, these engines are very strong.

I can find out if there is one as I happen to meet the inventor of the Rotrex supercharger on trackdays. I could give him a buzz.

Could you sort a bulk buy with him to please.......

Turbo technics used to do one for the k series in Elise. The rotrex site only lists Komo-tec as selling them now though

I wouldn't be surprised

How many are we talking about?
