How much power will a stock Demon/Redeye fuel pump support? And can these pumps handle E85? Thanks in advance Mike

I think the answer is, it depends. Probably 870 - 900 rwhp on gasoline (race fuel obviously for that kind of power). For E85 probably about the same before you run out of pump. I think most E85 kits include at least one JMS boost a pump.

thank you for the info! I think I'm going with a flex tune. The factory Demon/Redeye pump is 499.00. Just wanted to make sure the pump could handle a 2.85 or 2.72 pulley and E85

You won't be able to just drop in a Demon/RE fuel pump. There are FPDMs, etc involved. Get the dual pump drop in kit from @ostmike or @curt_dusterhofftuning

There's a video of it on my YouTube channel. I just put one in.
