look at the duty cycle of your injectors.

you injector should be capable for about 400hp at 80% duty.

calculation: 650cc/10.5= 61.9lb/hr

(61.9lb/hr*0.8(80%dutycycle))/0.5= 99.047HP (per cylinder)

99.047HP*4= 396.188HP

hey friend thanx for all this but i still have a difficulty in understading it. do you have any website from where i can learn more and i want to know the range of the boost which can i go on like by using 650 injectors can i go to 25 psi without damaging the engine? and i still have problems in tuning like i still dont know how to tune the fuel trim abd other things so can you help me please?

well, most of my information i got through friends, forums, school, university and, of course, a lot of book about engine building etc. in the university libuary.

there won't be exact information on the internet. no tuner will tell how to tune it right, everyone has his own hints and tricks. it's a business, where you can earn a lot of money, if you do proper work.
