Seller's Description & Comments
This car started life as a 2012 Ariel Spec Race Atom (SRA). It is professionally modified and now has:- A built N/A motor with 260hp/200ft pounds tq (up from 180hp stock)- Link stand alone ECU- A Quaife 5-speed sequential trans with no lift upshifts/no blip downshifts (in place of stock Honda 6 speed manual)- Twin disc clutch- Dual element Frt/rear wingsMore, see below.br style="box-sizing: border-box;" /IN STOCK TRIM, the SRA Atom:- Is powered by a Honda K24 and 6 speed transmission straight out of an 9th Gen Civic Si. Dyno testing showed the motor put out 180hp and 160 ft pounds tq to the wheels.- 4th gear is a weak point of the stock trans and is prone to failure, particularly under track/racing conditions.- Has no aero.- Runs on 205 Hoosier R7s in front and 225 Hoosier R7s in the rear.- Has a troublesome and antiquated data/video system.IN ITS CURRENT MODIFIED FORM, the Atom is fitted with:- A custom built Honda K series motor with a K20 top end and K24 bottom end putting out 260 hp and 200 ft pounds tq to the wheels. See gallery for dyno sheets. The engine has run only two test sessions and one race.- A Link ECU is installed in place of the stock Honda ECU. This allows greater tuning and data collection. The car is tuned to run on 100 octane unleaded. More power may be obtained if tuned for 110 oct.- A Quaife sequential 5 speed transmission allowing no-lift upshifts and no-blip downshifts. The computer handles engine cuts for upshifts and blips for downshifts. The trans was inspected and refreshed with a new input shaft, 4th gear and minor bits in November 2023. It was run in only one test session since.- Twin disc clutch- Mil spec wiring harness installed in 2022 - 2023. The OE engine and chassis harnesses were removed completely from the car and discarded. Mil spec wiring was professionally designed and installed for both engine and chassis. See photo of battery box for a sample of how good the wiring looks. The car has been tested and raced with the new wiring and it is 100% with no issues.- 245 Hoosier A7s in front and 275 Hoosier A7s in back. The car comes alive with the grip much wider and softer tires provide compared to the narrower, harder R7s. The Atom is so light that it is hard to get the R7s to their optimal temperature of 180-200. A7s heat up almost instantly to their optimal temperature of 110-140.- Rebuilt, re-valved and tuned shocks. See gallery for report on shocks from the tuner.- Aim SmartyCam GP2 camera integrated with the MXP data system.- A 2 port USB hub is mounted in the firewall just behind and to the side of the seat. The ports provide power to rear facing cameras to record the action behind. No such camera is provided in this sale.- Rear camera and monitor. This is separate from the SmartyCam. Camera does not record. It is to make backing easier in the paddock and to see competitors approaching from behind on track. Camera is mounted. Monitor is not mounted. Wiring with Deutsch connectors is all present. Mount the monitor, plug in the camera and monitor and it is done.- Chassis is reinforced. Even in stock trim, the Atom chassis is prone to cracking. With almost 50% more power and wider, stickier tires, cracking welds can be a real problem. Gussets are added to prevent cracking. See pictures.- Skid plate is fitted to protect engine and transmission. See pictures.- Lifeline 360 fire system with dash mounted handle for the driver and an external handle for rescue workers.- 2d seat with harness provided and now mounted in car.- Gulf livery is paint, not wrap. Everything that is vulnerable to chipping due to flying debris is clear masked, including the entire nose, side panels, blue sections on the tub and vulnerable areas on the rear body work.- Front/rear dual element wings with proper bracing to prevent vibration and movement at speed. Spares included- Second Kirkey seat identical to the installed seat. Seat mounts are in the car. Mounting hardware is provided. Update: seat is now mounted in car.- 1 set extra wheels with Hoosier A7s, 245/275- 1 set roll around tires- Several serpentine belts- 2 used brake rotors (front or rear), one used rotor hat. Rotors are fine in a pinch but there -isn?t much life left in them.- 2 sets of brake pads, used but have most of their life left.- 2 new bell cranks.- Two exhaust turn downs for sound limited tracks. These allow the exhaust to be pointed away from sound meters. In my experience, this can reduce sound by as much as 6db.- Exhaust discs for sound limited tracks. These are inserted into the muffler. In my experience, each disc is worth about 1.5db sound reduction.- Speed sensors, one new and one used.- Oil filter.- Several rear wheel bearings and grease seals.- OE radiator fan. The car?s fan is removed to increase high speed cooling.- One used control arm. It is slightly bent but is a good spare. The car aligns correctly even though the arm is slightly bent.- One used upright. I don?t recall why I replaced it with a new upright. The fact that I kept it means I thought it would serve as a spare in a pinch. It is best to consider this part unusable until it is put back on the car and the car is aligned.- Two throttle pedals (one OE and one duplicate of the OE pedal).- OE steering wheel.- Palatov suspension components including bell cranks, shocks and springs. No uprights or hardware (nuts, bolts, etc). I paid a bunch for this on Palatov?s claim that it would transform the car?s handling. I could not make it work but perhaps the new owner can. The shocks are brand new Penskes.- Assortment of springs (in addition to the springs that came with the Palatov suspension).- Assortment of rearview mirrors and two replacement lenses. Some of the mirrors are missing glass and some have broken glass. Two pair of mirrors can be had from those that are not damaged and the two replacement lenses.- Kirkey headrest cover.
