Found this on the PTE site shopping turbo options for the mirage.
from the site, "The only thing better than an Ariel Atom is a faster Ariel Atom" reads a quote on rspatom.com, a website featuring Scott Hodges' Ariel Atom 3 which is powered by a 9.7:1-compression Honda K20 motor.
Built by Real Street Performance and designed specifically to house their RSP Turbo System, this Atom features a Precision 6262 CEA ball bearing turbocharger, custom RSP manifold, downpipe and intercooler/piping, custom JE billet FSR pistons, Carrillo Pro H-Beam connecting rods with Carr bolts, a complete Ferrea valvetrain and Injector Dynamics ID1000 fuel injectors. Engine management is handled by a MoTeC M800 ECU system and SDL3 digital dashboard. Additionally, a modified gearing and tire package helps effectively transfer power to pavement.
Weighing in at a scant 1,375lbs (1,550lbs including driver and fuel), Hodge’s RSP Atom currently makes approximately 600 horsepower at 20psi on 93-octane pump gas which makes it the fastest Ariel Atom in the world!
Primarily used for fun, traction control components have been ordered and the team is currently discussing reworking the fuel system in hopes to turn up the boost on race fuel or ethanol in the near future as it’s currently close to maxing out capacity – they hope to make 750-800 horsepower and we’re confident that they will hit their goal!
