ok guys. I'm looking for some advice here.
I currently have an e-85 walbro 450 and 1000's. i'm wondering if anyone has made 700+ wheel with that setup, or do I need bigger injectors and or pump setup?
i'm going to order bosch 1700's, and I don't want to go dual pumps if the 450 will cut it.

anyone have actual experience with this???????
thanks......

I have read here and there about that much power but with 104 or C16. The E85 injectors need to be bigger by a large amount because the BTU content of alcohol is not good. But you knew that. I think you can find some of threads, possibly in the build section.

Yeah, basically the formula I've seen is, .5hp/cc of injector on E85.
Basically 1600cc injectors for 800hp. I'm sure this isn't exact, just a gouge number.

thanks for the replies. I talked to aaron at dm about it. looks like the one 450 is good to 600 wheel. i'm thinking about doing a surge tank. I did order the bosch 1700's and I have a dual feed rail already. just have to figure out the tank/pump issue.

is anyone running a surge tank, or second inline pump? if so, i'm open to any advice... :)
