hi can someone please let me know how much Hp will 680cc injectors support?

looks like 120 hp per injector at 90% duty cycle.

 

Maybe 120 crank hp but I don't believe 120whp per cylinder at 43.5psi fuel pressure...
I would think that they would be at their max by 400whp.

 

really depends a lot on your setup. how efficient/turbo range/fuel pressure.


usually you can get 450 whp out of them.

 

The general rule of thumb is 6cc per whp

680cc x 4cyl = 2720cc

2720 / 6cc (per whp) = 453 whp

The above equation works for gasoline and will keep the injector duty cycle in the 75-85% range. If you use E85, a conversion factor of 1.3 needs to be applied. Hope this helps

 

thanks for all the info..

 

Here are a few good calculators to help figure out how much HP the injectors can handle: http://injector-rehab.com/imcw/

or help you select the correct injector size based on the horse power you wish to reach: http://injector-rehab.com/issg/

Hope that helps
