Anyone running a Rotrex?

[Conor D]

I've seen a few videos on YouTube with Rotrex powered cars, most have modified engines along with varying between the C90 and C74 chargers.

Without much info it's hard to know what people have experienced as good setups with either - without modifying the engine.

Anyone here?

I have sent a couple. There was a company trying to sell a kit for MX5s but it didn't sell well for some reason, probably cost compared to the well established turbo or supercharger kits.
I can't remember who the company was but I think they had more luck with S2000 kits so it might be worth looking there.

Kraftworks.

By all accounts they promised the earth and delivered nothing - at least in the USA. Smog certification was one, modular upgrades was another i.e. IC kits etc.

The first batch of kits was also really poor quality where none of the brackets fit properly, they left the owners high and dry, wouldn't respond to calls for assistance.

Not surprising it didn't go well.

They seem to be actively developing their kit, might be worth watching the US forums to see how it goes...
