Oh,

If you happen to be using the 6 port and = plan to use=20 only 4 of the yellow injectors, they are only good for between 173 and = 197 HP=20 at 80% duty cycle and BSFC of .5.  You would have to use all 6 to = realize=20 that higher HP that they are supposed to = make.

I am thinking that they are sized small in = the car=20 because they don=92t expect you to be at WOT for long in the car and = they will=20 have a chance to cool down.  In our case they will be at WOT for = hours=20 and could overheat if they were at a high duty=20 cycle.

Thoughts??

 

Bill = B 

 

Bill,

I figure they ( yellow) would be = fine and=20 although at the higher end of the duty cycle, they would still be = below 80%=20 and better at lower RPM.

The figurers I put up previously showed = 400cc=20 would be more than enough, I think my figurers showed 760cc/2 being = the higher=20 end needs, but I would need to go over my figures again - could be=20 borderline.
