That most be a nice perk to your job to be able to get behind the wheel of some awesome cars
Yeah, ive got a GT60, have had it for ages, its quite comedy its so big.
Noise is insane, i felt physically sick after driving it for a hour or so, just the noise, honestly, and im deaf as a post anyhow
And when you giving it loads, daaamn
Ears are still ringing, but its just THE coolest sound, a mega big port rotary, evil.
13000rpm dont take anything really, thats the beauty of rotaries, in testing IIRC Mazda got over 35000rpm from them on a bench dyno or something fucking stupid.
Main thing is giving it the breathing to make it WORTH revving that high, so HUGE ports and equally huge turbo.
And some relativley minor (in the grand scheme of things) lubrication mods IIRC, but dont know exactly what, if any, but some 2stroke style pre mix is wise...
