This thread is for the results of the testing of the differnece pop pressure at the same size.   

 

ANY REPLIES NOT ON TOPIC AND OR WITHOUT DATA WILL BE DELETED.  

 

I will be running 3 sets of DAP injectors first set at 305 bar, next at 330 and the last at 350 bar.  We are going to compare real world situtations and what the pros and cons are of increasing pop pressure.   All tests will be datalogged and video taped if applicable.   

 

The tune will be EXACTLY the same for all injectors.  al runs done on Lvl 3, so no wiretap being used

How would 12v injectors work with higher pop pressures? I know my last 98 truck got great mpg after I p-pumped it. I kept the 7x.010's set at 305 bar. Truck started and ran great

We set up all of our P7100 pumps to higher pressures.  stock is 260 BAR, we set them closer to 280BAR for performance sets.

Glad the new 150HP are working well for you and MPG are up.

 

I'm really happy with my 100's set to 322BAR. Its about as smoke free as you can get from a Smarty.

You should add that in as an option for ordering injectors. The settings haven't changed but the smarty is smoke free.
