Well done. I drove the Mustang with the 2.3l turbo across the states on Route 66 and that flew. In your car it must be even better.

Thanks Griffo. I guess the light weight advantage follows through on both cars regarding torque transmission.

Yours now gives same torque as 3.7 Cyclone but (amazingly) at lower rpm!

The great feature of the 4 cylinder cars is their "chuck ability" compared to the heavier +8s and Roadsters .

With that amount of low range torque you have created something very special indeed, instant go AND good handling.

I must also complement you on your engineering skills and devotion to achieving your goals, not many of us would be prepared to take on such a project.

Absolutely. A fantastic result, you should be very proud of what you have achieved.

I've been watching your project with great interest and thinking that my ARP4 could do with some of the torque you have at your disposal. The only thing stopping me from going down the same route is the fact that if I change my engine, it will no longer be a Cosworth ARP4 and therefore will knock a large chunk of value off the car, on top of the cost of installing the engine - a double whammy.

Well done on the whole job, it must have been very satisfying?

A great report! I read about it at first in the MSCC magazine. And I think: ohoh, out with a trailer, back with the trailer and an engine... And I think a lot of wives are not happy. They can't see the real worth ;-) (of the future fun). I know it, I' ve got a classic MINI and I found some engines...

Than I see your way: a lot power for (nearly) a budget. And I was not far away to travel to Britain. To collect such an engine.

But than after a cup of coffee it was clear I could never get a chance of "TÜV"/ MOT in Germany and than after 40 years experience in frontwheeldrive cars I' m affraid that on twisty roads the back would be faster than my reaction.

I see you've done it right! And I'm still learning.

René

The story below is just an example and could happen with a Morgan/Rotrex combination in the same way.
The very car at the link here is actually my Elise equipped with a Rotrex charger.
https://www.rotrex.com/centrifugal-superchargers/lotus/lotus-elise-exige-220s-toyota-1zz/

This all happened 12 years ago, I still have the Elise but it was a very rocky road for a long time! I would NEVER do this conversion again and can advise anyone against it or you take it that you can get into the shallows of unpredictable traps and problems.
After a quick fatal engine damage the tuning garage had to change essential parts of the engine and it worked only reliable by using other connecting rods other pistons etc. so that the compression could be weakened. Since then the engine holds over 56.000 km. The Elise delivers 260 Nm at 4000 rpm and 220 hp from the 1ZZ engine, so a little less power but stronger torque at lower rpm than the 2ZZ conversions.
I would never put a Rotrex charger simply on an engine that is designed as a naturally aspirated engine in terms of compression. Or you work with very little boost pressure but then you must ask yourself if the weak result is worth the costs in relation.

Back to the topic,
Griffo, in my view you did the only right thing with your decision for a complete engine solution.

I don't have any complaints against Rotrex conversions, but one should be careful what he could get involved with.
