42lb injectors?????? Isn't that what they use on hypo turbo's??????? Tell me its going into a stroker i6 , to obtain that kind of flow out of 4.0l i6 would need to spin to 10,000rpm lol!!!!!! Thats not an injector that is what is better known as a donkeys penis
 .
Ohowww!! I can sense an abusive post coming up |

my engine (~150rwkw) hit 100% duty cycle with stock injectors at 4000rpm. With '21lb' injectors it was at 96% duty cycle @6000 rpm (was actually 24lb running at lower fuel pressure).
By doing the maths I have figured out that for a I6 engine you get an ideal 6.6rwkw/lb of injector (you can get more but the duty cycle will be above what is normally considered a safe margin for error) so ... 19lb ~125rwkw 24lb ~160rwkw 30lb ~200rwkw 36lb ~240rwkw 42lb ~280rwkw sorry for pushing the thread off track, might try to post a bit about ITB's later.
