One of R.N.R Autosport customer have upgraded his machine.Previously it was stock 20v Blacktop with metal head gasket and adjustable cam pulley on exhaust,was run by Adaptronic e420d ecu with R.N.R Autosport COP conversion kit.
The owner have upgraded his cam to Toda 264-264 9mm lift.Others remain untouched,even the piston is OEM 81mm. OEM Rotating internals have been balanced.
The blue graph is Toda Cam run with previous tune,the red graph is Toda Cam after tuning the ecu,the power drop above 8000rpm is due to cam settings,the owner will send the car to his mechanic to optimize the cam timing and hit the dyno again.The VVT is still retained in this setup.The gain is almost 9HP, i reckon it can get more than 160HP on this dyno with proper cam dialing setup.
Fuel is RON97 with Octane booster.
that was the best toda 264 could give..
ReplyDelete272 will drop around 9200rpm..
288 will drop around 10200rpm..
304 will drop around 11200rpm..
i already have tried all set ups with all cams i've mentioned above
Yes around this figure,could tweak a little bit more with slight adjustment on cam settings.
