These are the injectors of choice for a stock appearing turbo on E85! I wish I had purchased these puppies instead of my RC 1000 nozzles.

 

your missing my somewhat skewed thought process.

stock injectors hit their absolute limit (go static?) somwhere in the 105-110 range in evoscan. that being said im pushing 103 from 6k up on stock injectors. ive always tried to keep my setups on every other car ive owned below 90 to be comfortable.

to me that doesnt mean im out of pump, it means im out of injectors. the thought was that putting in th ebigger injectors will give me a little safety pulling the idc's way down without requesting anything more from th epump for the time being. i know i need a pump, i just need to hold off on putting it in for now if possible.

as far as e85, its doubtful it will ever happen since i live in a state with zero pumps. it was just a thought in case i move at some point in the next two years. otherwise i just need enough fuel to support cams and the possibility of a stock block red/bbk setup.

 

If Aftermarket pumps are too noisey for you, consider:

A double pumper set-up which utilises two stock pumps

 

Orr hardwire stock pump to

 

I ran the stock pump on my IX and reached a point where it dropped fuel pressure. I have DEFI gauges so I could play back my runs and noticed the fuel pressure dropped at ~23psi and high rpm. I then swapped to the Walbro and fuel pressure remains constant. With the Walbro I don't notice any excessive whine from the pump. I would not recommend to add injectors without also upgrading the pump. Depending on your hp goals you may want to look into the Walbro or the new Aeromotive, which seems to provide the most flow for a single in tank pump.

 

You really need to monitor fuel pressure at full boost and high RPM to safely conclude it is not a pump issue.

 

so did you get an answer? bigger injectors without a fuel pump?
