David,

How far off is your Evo X solution? I say solution because I know you've stated the kit for drop in is ready except for pricing but am presuming due to the very large increase in flow as you've stated we may need to have some supporting modifications to keep things in check.

I've been looking into fuel solutions on my new X and been really torn with all the reports of fuel starvation etc. with 1/4 tank of gas and such with various setups so this really appeals to me.

 

twin buschur pumps and keep some gas in the tank and you'll be fine

 

It's very disappointing to see that you are going to make up a sarcastic fallacy to give the illusion that I use you as my go to source when all I have done is ask you one single question of your experience with the Denso 1 step colder plugs for the IX. Poor form Mike.

What argument? I inquired about a possibility to make this 400lph pump to fit the Evo8/9 and was met with condescending insults instead of what could have simply been an educational explanation. I still would like to personally pursue an affordable solution to make this pump work with the factory housing. I'm not a vendor nor a competing company so I still don't understand the hostility you direct towards as if I was trying to undercut you with a product of my own. I have never told anyone to not run your products nor have I ever bashed any of them either. I'm simply trying to think out side the box which is what others have done to help take this platform where it has Evolved too today.

 

How about we just stop snapping at each others throats and talk tech more?

Somebody needs to be the bigger man and just drop this BS.

 

+1
it sure is entertaining though... Pride is on the line it seems.

 

i think this kid should give it a shot, try and make one fit and get back to us with the results. with enough time its possible. Hell if i didnt already make my own DP i would give it a shot.

 

It's too bad it won't fit. I read this whole thread, and no-one mentioned or thought of using two of these in the Buschur double pumper. Now that would be awesome. I have the Buschur double and its very clean install/ works well.

 

Even if its fabricated, it needs to be a cheap kit. Real low cost or the pump will shoot up in price and be near the cost of a double pumper. At that point nobody would run it. The realquestion is how cheap can you fabricate a kit? Most likely not cheap enough.

 

Oh boy, some of you guys aren't reading what I am saying. I have the pumps HERE IN THE SHOP. I HAVE ALREADY LOOKED AT MAKING IT WORK. Sheesh, I am trying to tell you guys that by the time you make it actually fit, not make it fit with some "shim" that the cover won't go back on with, but actually make it fit, then the price difference will not warrant using a single pump that flows less than a double pumper........I can't make it any clearer.

Double pumper usage, already thought of it, waiting on our tops to come off the mill to test fit, I see no reason that two of them can't be used other than maybe fitting them through the hole in the top of the tank. Now, the absolute fact is using two of these pumps will require the fuel lines on the car being replaced and a large aftermarket regulator to be used, the siphon would probably need to be eliminated too or highly modified. So now you are talking about complete new fuel system lines and all.............something that the double pumper we designed has pinpointed eliminating. Yes, I'd build it for someone, we have AN fittings for the kits, so you'd just have to buy AN lines/regulator etc. and go through the work of putting it all on.

I will put this out there. 99% or more of you will NEVER need that type of fuel delivery. My car runs 9.0 at 159 on our double pumper with 1200 cc injectors (on gasoline). With the new 2000 cc injectors that work so well, the fuel delivery of the double pumper it's just something that isn't needed.

 

Sorry, more thoughts. The stock fuel line with our current double pumper is the biggest flow restriction in the system but my car had STOCK lines on it when it ran that 9.0 and had fuel left over with just 1200 cc injectors. So, at some point IF you have a double pumper and start needing more fuel my recommendation is, so you don't destroy a good EVO, take the stock feed line off the car, neatly. Replace it with a rigid 3/8" stainless steel line, in the same holder and up to the frame rail in the engine bay. It is time consuming to do right and you will need a quality tubing bender like Rigid Tool makes. I have a few guys who have gone this route and just used AN line the entire length (which I do not recommend/promote or like) but the IDC's dropped substantially when they did so.

Using our double pumper with just one of these pumps in addition to an already modded Walbro would cause the factory fuel line to become even more of a restriction.....

 

Oops............edited, woke up at 1:38 am, information incorrect.

 

If the need becomes great enough for the 8/9 then someone will build it. Thats just way things work. Id rather just buy the best solution up front which for me was the double pumper. This will be the last set up I will ever need on my car.

 

What is the point of this thread then folks for evo 8/9 owners. Double pumper it is! Thanks for info

 

David quick question, with just one of these bad boys in the EVOX, no rewire kit, what will the base fuel pressure be, and will it overrun the OEM FPR? Thanks

I can do the testing myself if I had one handy, but since you have a stash thought I would ask!

 

I started an x-specific thread, and Buschur said it would def over-run the stock fpr (or parts pertaining to it).
