We have made 643 on PTE 1200's and a Buschur double pumper. So your injectors are not going to be the problem. Although I have seen a single Walbro do 570 on e85. So I would think you would be close to 600 on a Dynojet with the Aeromotive!

Yea his double pumper is probably the most recommended. I just had a local guy modify mine for me (basically the same thing), but unless you trust the person I wouldn't recommend that route

Burchur's kit comes with all the pieces I explained and actually might also use a different method for the second feed line. If you have strict emmissions you might want to keep your evap emmissions stuff. He takes care of the secondary line routing as well so just call them up and they would be able to explain it to you I'm sure. I don't think he uses AN stuff, but I am sure whatever he uses works fine.

 

Ok, i think buschur connects the 2 pumps to the orginal line? making the orginal line a restriction? or does anyone know the capicity with 2 pumps on orginal feed line?

 

It depends on your injectors, boost pressure, fuel type, etc. but it will handle over 600 WHP in any event.

 

Now that you mention it, I see that he might just Y into a single -6 sized line, which apparently works fine. Whatever he does, I am sure it works as there are tons of people with his kit out there.

 

The buschur double pumper feeding into the stock feed line is good for 700+ on a dynojet, more than most people would be to max out... If you are going to play with E85, do youself a favor and just get a BR double pumper and call it a day...

As far as a hobbs failing, I have personally never seen one fail, they are pretty resiliant...

 

I am there now... 1200cc injectors with a A340 will not make 600 WHP on E85 not even 586whp I think.

 

Yes. Inline 255 and a 340 will get you to 560 or so on E85 if at 30psi or so. We made 590 on that setup but were running a 13.0 out the top. Switching to 1450s and a Buschur double pumper fixed all of that issue.

480ish in my experience on 1200s and one 255. A 340 only seems to have enough to give maybe another 20whp or so. Luke did 509 on his car with the Green with a 340 and E70.

 

I bumped the base presure to 55psi and running walbro 400lph... still need to take it to tune.... I dont like the idea of dubble pumpers... if one of the to fail.... buy buy engine! I rather run series pumps.

 

How would a series pump failure be any different than a parallel pump failure? Either way you run way lean. I had two pump failures when I was running in series so I know. So far running in parallel = 0 pump failures. In series, you either run them both all the time and deal with part throttle and idle issues or you push through a pump that is off and run into the issues associated with that (more idle/start up issues).

 

Hi all, i have installed a fullblown dual hanger with 2 walbro 255 in it. new an lines to the feed.
I hear a lot of people saying that the walbro will brake if driving with E85, is this true?
How much power should my current fuel setup handle?
