- Seeking Double Pumper Advice -
Long story short, I'm fairly new to Evo's in the grand scheme of things. Not new to the scene, this is however my first "full" 4G build. So! Car in question is an '06 Evo 9, build list is as follows:
(Quick list to help provide accurate advice)
BR 2.0 (Std. Rod)
BR Stg. 3 Head w/ Supporting Components (Valves, Springs Ext..)
Gen. 2 6266 - T4 - TS - 1.14A/R
GSC S3 Cams
BR COP w/ CDI
Magnus Manifold
Boomba 70mm TB
AEM S.2
Build is almost ready to go, I just need to wrap up my fuel system. I have ordered some FIC 2150 Hi-Z's, however I have yet to order a new pump(s). I've been reading a lot about the Full Blown Double Pumper and the Buschur Double Pumper, both of which seem to be very viable options. I have ran across a few posts where there were fitment issues, ext.., so I wanted to reach out to those whom have used either Double Pumper and get some actual feedback on your experience, build quality, ext..
To be honest, from the many hours of reading I've done on both Double Pumpers, it doesn't sound like you could go wrong with either. But we all know the Internet and reading horror stories, or stories from disgruntled customers isn't always fair to the manufacturer, nor do I feel like it's an accurate way to form an opinion on a certain part, which leaves the forums as the best solution for "real life" experience.
Thanks in advance for any information, experiences, or input you provide. I appreciate the help.

ive had two full blowns.
One did leak some... not bad.
the other didnt.
i did run out of fuel at about 750/525 (dynojet), running two 255's.
ive heard, even with 450's you cant push much more through the full blown.
could be from fuel turbulence in the inner machining, but that is just my guess.. not a fact.

What power levels are you going for? A single walbro 450 rewired with 2150cc injectors is good to 700hp. These days a double pumper is no longer a necessity because if you were trying to make more than 700hp and still have fueling problems you should be looking into weldon pumps.

Thanks for all of the replies guys. I appreciate the "actual" experience sharing, some posts like this post (for example) can turn into pissing matches quick like. I appreciate the technical information, thanks again.
As far as HP levels, I'm expecting to max out the 6266 pretty quickly. This will be a full flex build, but primarily ran on E98 or E98 w/ 92 Oct. mix. No H2O/Meth, or Oxidizers, ext.. On the current build on full E98, I expect to be over 700whp.
Depending on how the car performs, I may go w/ something bigger, ie: 6466/6766 or 42R, ext. Since this is my first full build done on a CT9A platform, I wanted to start conservatively, learn as much as I can, then work my way up. I'm sure it will be one hell of a car once I'm done though, I'm just as interested in gaining the knowledge from/with this build, as I am with the Dyno results. Hopefully that makes sense?
Truth be told, I also want to keep things simple, which is why a Double Pumper seems so appealing to me. I can rewire singles and get there, I'd just rather dump two into a housing and bolt them up. Besides keeping things clean, there's tons of more room should I choose to go bigger, so I want have to change much once it's in.

If you're curious as to why E98 vs E85:
Believe it or not, E85 is pretty hard to come by in the Seattle area. Fort Lewis is basically the only place around me that I can get it reliably. Since I'm not enlisted, or a veteran, this poses a problem.
Since E85 and E98 are about the same price when bought in drums, I chose to go with the later. Storage of a drum can be tricky, but I have a 6 Bay heated garage, with a fire system, so the "risks" associated with storing fuel, or water getting into the drum are pretty minimum.

However, with that said, I should be in the 700whp neighborhood on full E98, so I'm thinking running a set of twin 450's isn't such a bad idea after all. Who knows at this point, when I bought the car I said "I'm not going to 'mod' it, it's fine how it is".
$20,000 later.. Here I sit..
Thanks again man!

The reason I went with 450's is walbro rates that pump for e85 usage and the 255 is not. Countless people have done just fine though on e85 using 255 pumps. Good luck with the build

700whp (dynojet) is extremely do-able on a twin 255 setup. Tom from Tscomptuned just did it on 1 450! Keep in mind if your going with 450's, you will most likely over run the factory fpr.

And thanks man! I'll be sure to share the build once it's running. I would say "complete", but we all know there's no such thing.
