Clio 197 supercharger

Has anyone here install KTR supercharger kit? Is the standard engine really capable of producting at least 280hp, is it safe? anyone tested this kit on track days?supercharger_kit_c3rs_f.jpg
 
Engines are quite strong but it’s the gearbox that’ll go first
I dont know about the engines... I had a sport cams and rebuilded engine and the engine after 3k km throw the rod out... Now my new engine is OEM with ARP conrod bolts and it runs fine...
 
My supercharged clio has been built 7 years and done many track days with just arp rod bolts. Good to go
