Default E85 conversion

So I have my c5 with a vortech v1 Si trim on it. I’m looking to see if my current set up will tolerate this conversion.

I have:
a stock bottom end ls1
Vortech V1 Si
60# injectors
3.6 pulley now, but dropping to 3.33
walbro 450
kennebell BAP

do I need to change the fuel pump, add another additional pump or an in line pump. Is it good the way it is?

tune right now makes 528 whp/476 ftlb

trying to to get to 590-600whp safely

Any feedback would be greatly appreciated.

thank you

Not really based on what the OP asked. That thread took a tangent.

OP, the first thing to do is know what your injector duty cycle is. E85 is going to require about 30% more fuel. Your fuel system is going to need the support your current requirements + 30% without going over about 80% IDC.

The other thread is more about how to enable E85. And it's a bad thread about that too.

I believe the title should be revised as it is a double to site and most of what op is asking is covered. I created that thread last year. I have to disagree it’s a bad thread. Boosted with e85 would have been a new thread but I could be wrong. Then even that was discussed. Please check it add some 2 cents to the thread. It does cover a lot.

I totally agree with you man, and thank you for answering this. The other thread is not at all what was asking but it’s ok. I found a complete kit that offers two 325lph pumps, the hat, all wires, sniffer, sensor, and everything needed for an e85 flex fuel conversion. I’m going to buy this but I’m going to buy another 450lph as I just put one brand new one in about 1 month ago. I’d rather have overkill when it comes to fuel supply.

if your car is pre '03 pm Blownbluez06 and get one of his twin 450 hangers, that's what you need for big power on e85... I don't think the 450 will fit on the hanger that holds 325 pumps... fore makes a nice triple pump setup for the 03+ cars as well
