You don't think those are valid questions? That's over 1000 hp on gasoline and even if you want to propose using it on E85 or E100 a Walbro would not be my first choice for sure.

If you believe yourself to be beyond reproach then you probably shouldn't. Such a pump foesn't really fit in this general subject either, but I suppose you will take that personal too.

 

I am not taking it personal and beyond reproach I am not. I did not state it was a viable solution to OEM but from what I read it can be used on applications <400hp. Which a handful of members on this forum do fall in that category. As far as I can tell it hasn't been discussed at all on this forum and with it being a few months old I was shedding some light on the existence of this product. I am not making any claims of how it can or would be utilized.

Last I checked this thread was in the major hp upgrade section not the Trouble Shooting

 

Yes, very few and the 255 lph Walbro that is discussed here and has known reliability issues will get you to near 600 hp, and there are several threads discussing the 300+lph Aeromotive pump

more is not always better, especially if you prefer not to be heating your fuel up by recirculating it continuously due to installing a grossly oversized pump

 

I am aware of the previous/current issues involving Walbro pumps. The Aeromotive pump has issues as well on other automotive applications but I have not researched if there are issue similarities on the Rx8.

I don't claim to be knowledgeable on why a particular pump is used in certain applications and not on others. Or why it is/isn't a bad choice for the Rx8. I leave that to the experts and that is why I posted the link in the first place. So it can be discussed and learning can take place. Thanks for your input.

 

It seemed to indicate a bigger must be better thought process rather than an understanding of the subject. 400 lph is mega-overkill. Maybe this will help:

The point of all this big fuel pump discussion is that you no more want too big of a fuel pump than too big of a turbo. There are ramnifications like excessive fuel recirculation, high amp draw requiring larger power supply wiring etc. even people using the smaller Aeromotive pump face this issue and may want to consider slowing it down with a pulse modulator or something similar. In theory the pump will live a longer life too.

I did a bit of searching but I can't find a how to swap the existing S1 fuel pump with a Walbro. Anyone have a link they can share please? Any rewiring required?

 

I haven't read the entire thread front to back, but has anyone tried a deatschwerks 255lph pump?
It seems like it might fit, the walbro p/n used in the 8 is used in sti's and evo's, deatschwerks makes pumps for them so it would seem pretty strait forward.
Am I missing something. Emailed them just waiting on a reply to see if they can shed some light.

 

No rewiring is required, however the walbro is slightly shorter than the oem pump. The BHR kit supplies you with the proper size o-ring that makes up for the extra space. Their price is in line with what you would pay for the pump from any other source.

 

I bought the pump only from BHR but I did not notice a seperate o-ring unless it was already mounted to the pump itself.

So basically all I have to do is follow MM's instructions on page one to disesemble the pump assembly. Install the new pump...Then melt the siphon pop up?

Anyone know where I can get the special removal tool?

 

I suggest you contact BHR and see what they have to say about the o-ring. Otherwise yes, just follow the instructions. As for the tool, I borrowed one from a member that doesn't visit any longer (Swoope).

 

Is it cheap? Maybe I'll just buy one.

 

LOL...it's an o-ring.... about 10 cents if you can find one

 

or you could actually read and comprehend the thread since it was already discussed in detail

 

I swear you have a macro setup to to auto type this sentence every chance you get. But your assumption is only 50% correct as I read half of the thread.

Not to mention I was not talking about the O-ring (should have made that more clear)...I was asking about the removal tool which I need quickly. If someone were to give me the name of the tool the search button would be more useful to me.

 

Disregard questions above...I got my answers thanks to Ray.



MM,

I read in one of the previous posts you mention installing the new pump may require a retune if you are experiencing starvation at WOT. My question is: can I install the new pump, even though I am on my third tune, and perform WOT? I want to make sure I can still do the datalogging for the next tuning session. So far the only occurence of starvation, to my knowledge, is during high G's at an autocross.

 

Damn, I did read the whole thread and it wore me out! I'm glad I have a couple of days 'til I get my pump so I can rest up.

 

really,

and misspelled my name you dick!

caveman, i have it. am using it tomorrow to help a local... i could ship it out monday.

i think you have my email address shoot me one. or pm me. i am going to be around a bit more. got stuff to figure out.

now my question. is the areomotive pump mentioned (i think that it) just a pump or an assembly? if it is a just a pump will it fit the 09 housing?

beers

 

[Maxwell Smart voice]Sorry about that Chief.[/Maxwell Smart voice]
corrections were made.

so i have a few options..

1 the stuff that is in my car now.

2 a fuel pump that was never named, but run in a 04 to 8 serious mod and did well.

will it fit in the spare 09 fuel pump housing that i have laying around?

or is the areomotive something different?

btw, did you cut your hair. looks good!

if i offend you, i am really sure you have my phone #! btw, if you call me i gots a billion questions for you. fail, fail

btw, got the right question in the right place.. really? !!! i thought i really posted in the cobb forum or something like that! dick!

beers

 

See my post to him above...I seriously thing he's testing out some new macros. Imagine the old west when the gunmen are facing each other to try and see who has the faster hands. Well, team has developed these new macros of awesomeness to dish out newb pnwnage with a single key stroke! With a stroke of a single key you too can be pnwned by Rx8club's newb security guard. GO TEAM!

[/TROLLIN]

P.S. PM sent...THANKS!

 

First, I am not offended. I'm concerned that you turned into some dufus n00b during your hiatus

Second, outside the DIY area I am just another member with my own opinions and viewpoints.

Third, I wouldn't have to be a dick if you weren't acting like such a 'tard You're not some moron n00bie so stop acting like one and also stop being a role model for other moron noobies to do the same by posting up lazy *** questions when you darn well know how to search and that you should be doing so

 

i could not think i could offend you, as i think our humor is kinda the same. but i did ask a serious question or two in my post.

and as i have been in time out and way behind in the catch up game i dont expect an answer out right, but could someone throw me a link.

but if you think i am a dumb stupid newb, i am cool with that as, your one of the few people here that doesnt owe me money...

beers

 

Successful mod and install. Thanks to all the good people who contributed to this and the many other helpful threads.
Cheers!
