Hi wyn ,
It was a std re-build by Aaron at HT , about 2 years ago i think . It did NO work at all as Finlays wiring meant it never ran properly , eventually i got him a chip and some greens and it did a trackday at brands , the splitter was a Cut Down Filing cabinet side and the fuel tank was ratchet strapped in , i had no more to do with him or the car as i felt it was dangerous and bloody stupid to use like that .
HT's std spec was/is about 7.6:1 , piston cut outs , balanced , 4x4 pistons , it wont have been much more special than that . The ecu had a chip from scott at Julian Godfreys , it seemed to go well when i saw it .
