thanks guys, she has 500 bhp and 512 ftlbs torque per tonne , so have found nothing on track that can catch me yet. On my last outing at Rockingham two 911 Carrera GT3 RS's were going round together and they couldnt catch me.
I'm using a 3.09 diff ratio so it will do 80 mph in second gear, 70 mph its cruising at 200 rpm and according to a gear calculator at 6800 rpm she will be doing 195 mph
but i wont be driving it.
Its mainly a track car but is fully road legal so gets used for the odd sunny day blast but she is a little scary on the road.
I have always had rotaries and rx7's, the next logical step was to put one in a lightweight car. I think the rotary is a perfect engine for a kit car, small, lightweight, loads of revs, cheap to get hold of and 500 bhp is fairly easily achievable with the right mods. Also, the gearboxes that come with them are great and strong enough in a lightweight car.
