does anyone have a list of what injectors to PSI to use safely?

I need to get some injectors and I've heard different things, so can we set up a list, chart or something?

thanks!

 

I know 650's can safely support 400whp without going over 90% duty.
I would say 880's would be plenty for most of us and I don't think you need to set up and injector driver for those.
1000's are overkill for most setups, but again you would never be limited by them either, you would need to upgrade to a dual walbro setup or a-1000 setup for fuel first.

 

Is there a kit for dual walbro setup
Any pictures out there ?

 

so how much boost can 550's support at 90%?

 

Just get the 750s. No reason to get less.

 

It has nothing to do with boost and everything to do with flow capacity. If 650s can support 400-425 rwhp, 550s should be able to support 550/650 of 400-425 or 340-360.

Honestly, next to HP and Torque, I think boost is the most commonly misunderstood engine topic.

 

I think someone on this forum has set it up. Take a look in the UTH forum or do a search for dual walbro's and see what you can find. I would personally just go with the a1000 even though it whines a good bit and you need a sump. Not very good for a daily driven car.

 

LOL the stock injectors can easily handle 60 psi

i have 1000cc injectors using the injector driver should i downgrade em? i dont plan on makeing more that 450rhp max

 

For a supercharged setup these will fit the bill nicely.
