ill be running a t3 on a 94 integra about 7 pounds what size injectors should i get ?

 

first to find out you have to decide on what hp you want at the flywheel. Then you take that number and multiply it by BSFC(brake specific fuel consumption) which is for a turbo car is about .55 to .60. After you do that take the number of injectors you are using and multiply it by its duty cycle which is about 80%- 85%. now you take the answer you got from BSFC times the flywheel hp and divide it by the number you got from the injectors times the duty cycle, then you multiply it by 10.50 and you got your answer.

Example:
300 (hp you want at the crank), 4 injectors are being used, 80%(ruff estimate for the duty cycle), BSFC is about .60.

now it is (1) 300*.60 = 180, (2) 4 *0.85 = 3.4, (3) 180 / 3.2 = 56.25, (4) 56.25 * 10.50 = 590.62
So you would say you need about 600cc injectors

 

as well as a standalone to control them if you don't have one already. Hondata, AEM, etc.

 

cool ill just get dsm forget doing the math

 

That makes no sense because you could hurt your performance going too big.

there's nothing wrong with going with a big injector...i run 720's...

 

whats the conversion, for lets say 60lb injectors, and 650cc??

what is the conversion from lb to cc??!?!?!
