SDS...DYNO...new Fuel pump
Well i completed my second run at the dyno and even after the installation of the walbro 255 fuel pump the car is still running lean at top end. but before we stopped i dynoed a 259.7 whp. the last run we really cranked the settings on the afr up ALOT and we dynoed 255.9. it is not running as lean as it was but it is still lean at around 13.7 at 6500rpm. so i guess next step would be bigger injectors. currently the kit comes with 270cc and i think i should go to 310cc. i will have to talk to ROSS and see what he says. the guys at the dyno (PRUVEN PERFORMACE) said that maybe an aftermarket fuel filter or different fuel lines. what does everyone think?
but overal i couldnt believe it 259.7.....i am happy with the numbers but not happy about the running lean part. good thing is we didnt hear any detonation on the dyno..hehe....i am trying to stay positive with all this. FYI....it is really frustrating being the first....it takes alot of nerves....NERVES that i dont have. i am pratically shittin bricks everytime we did a pass.
