walbro pump failure and e85/e98?

[slowgsr]

Hi.. I want to run E85 next season or perhaps E98. I found a ethanol supplier locally and Im going to see if I can buy e98 by the drum. Anyways, has anyone experienced any type of fuel pump failure while using E85 or E98? Im running dual walbro's intake and don't really want to switch out to different pump(s). If its going to be an issue with these pumps I may just run C16.

Please, if you can report a failure mention how often you drive the car since I don't drive mine often other than track days.

On another note, anyone have any idea how much power a -8 feed using E85 and dual intake walbro's can support? I think the walbro's can flow 800hp worth of fuel, im just worried about the -8 feed, it would be a simple fix to swap it out to a -10 though (inplace of my current -6 return).

Thanks guys.

A single walbro is only good for about 5-600hp most people seem to run out of fuel at the 500 mark while others can go higher, a lot depends on your setup. For an E85+ fuel system you will be running at least dual 255's to get 500whp.

Cost comparative, buy enough fuel system to run E85 and you will save $14+ per gallon and have the same performance with E85 vs C16, very different fuels, but can produce the same results. If your planning on 800hp+ you might as well go with VP import or E85/98 could get you there as well.

I am currently using dual intake 255s, in parallel. I'm just wondering about specific walbro failures with either e85 and e98. I will probably upgrade the feed to a -10 and see what kinda power it makes on e85 with the dual 255s and -10 feed on e85 providing I don't hear about too many short term walbro related failures using e85. If I'm looking for more power than I feel comfortable with on e85 I will switch to e98. I found a local ethonal supplier I'm going to attempt to purchase it through because a very consistant blend has always been another worry when your pushing the limits. I like the cooling abilities e85 has too always nice to keep them skirts cooler

So any walbro failures with e85? And do you guys think dual 255s and a -10 feed will support/flow UP to 800 on e85/98?

E85 or E98 don't cause Walbro failures and -10 AN or even -8 AN feed will certainly support 800HP, but you'd have to do the return line too and get bigger injections and maybe switch from stock fuel filter to an aftermarket with steel filter too.

I don't if this is a case in Canada, but E85 suppliers in the US do winter blend which is the equivalent to e70.

By the way, which turbo are you shoot for 800hp?

Ive ran E85 for years on a walbro with no issues, as have several others around here.

Also dual pumps in series increases the pumps ability to overcome head loss (pressure drop) which is not really the problem. Pumps in parallel will increase volume and have a much greater effect on flowing more fuel. Its basic fluids engineering

thankyou. The car already has a -8 feed with an fuel lab filter and I have some injectors that will do the job. I will be getting e98/85 directly from the manufacture so hopefully the blend will be spot on.

So it seems my dual intake walbros (parallel) and current fuel setup should be fine and walbro pump failures aren't common so I should be good to go. I read some stuff at nabr about failures so I figure I'd get a second opinion.

I believe there's a wiseman on here that ran out of pump using dual walbros and e85 at just over 700hp. -8 feed -6 return.

It'd be nice to know if it was in parallel or series though. It seems that everyone use to run them in series but now people are catching on that parallel is the proper way to do it using same size pumps.

Although, using a small pump to feed a larger external pump is a different story and probably why everyone thought it had to be done that way.

But to the O.P. Go with the walbro's. Even if one does go out in a few years, theyre pretty dang cheap to replace anyways.

Parallel Walbro 255 can handle over 800 HP.
