O.K. so, they use more volume like I claimed, (due to the increased fuel capacity) but why do they require a higher opening pressure?

 

i think the pressure needs to be higher due to more fuel being injected and with bigger nozzles it takes more pressure to atomize the fuel efficently, i maybe totally wrong though

 

They will need more volume of oil but they will not have a higher opening pressure

 

I concur. Thank you.

 

I installed my rosewood injectors 2 months ago love them! i didnt have an intercooler at first and they ran just fine. Got kinda hot really fast when pulling the racecar to the track this weekend. So i just installed a water/meth kit yesterday and went for a drive while pullin the car again... it was just fine cooled the egts about 250 degrees. Water/meth is way cheaper too! 554 dollars i got a snow stage 2 kit...

 

Just FYI, you can easily build an intercooler system for less than 500 bucks...

Glad you got your EGT's under control...

 

I have less then $150 into my old IC setup
