you also cant go by horsepower levels... different gases and some gases like e-85 require alot more fuel then most people think...

 

Where do you see double pumper?

 

bump.. would love more info on this.... im looking to get 750+ on my setup..

so far got PT 1600cc injectors, forward facin mani, PT 67/65 bb billet wheel turbo, kelford 280 cams

not sure what piston and rods to get yet.. but I was wondering should I install the dual walbro pump setup? Ive been hearing yes and no's about this duel pump

 

if you are going to make more than 500awhp, it's a good rule of thumb to go twin pumps

 

ok i have a question for everybody in here now. mellon you told me to just got ahead and upgrade to double pumper. so im adding that to my buy list but im confused as which one to get. i decided to just make it easier and get it from mike. what is the difference in this two besides price

one cheaper then the other. is one a complete kit and the other custom fitting lines would it be easier for me to get the more expensive one seeing as how it looks like its a complete kit with all parts needed or what? is one a basic install while th other is not. most likely kevin would be putting it in place anyways just want to make the right choice in which one to get

 

yeah.. i know that already..

but.. ive been hearing it will limit me to about 650whp on e85..

just wana see a setup that made like 750 with the duel pump with e85 .. if even possible

 

Thanks for the question.

Our dyno reads low as hell, everyone knows that, so using my numbers from my dyno is tough. So I will give out as much information as I can.

We offer the double pumper, which is a complete kit for $500. Nothing extra to buy, comes with fuel pumps, switch, wiring etc. Done deal. That kit uses two standard 255 Walbro pumps. A single Walbro pump will make 500 whp on our dyno but at that point is at it's limit and fuel pressure is falling off, that means you have to ramp the injector duty cycle up to keep from going lean, not a good way to do it.

If I use a modified Walbro, which elminates the pressure relief valve then the pressure will not fall off at 500 whp on our dyno. Doing that modification to the pump is NOT recommended by Walbro, they highly advise against it.

Now, I have done extensive testing on the fuel system in the EVO because I refuse to put AN lines on my car a cell or cut it or the wiring up.

The stock fuel rail is good until about 700 whp on our dyno BUT is a restriction at much lower fuel flow requirements because of the small inlet to the rail.

I thought the fuel lines were a restriction in my car. We built a twin line kit that uses all factory components, I am running it on my car now. It did drop duty cycles but only about 5% if my memory serves me. That tells me the single line is not much of a restriction either.

My car, last year, on our double pumper (modded pumps), single stock fuel feed line, stock return line, BR fuel rail and stock regulator with only a single set of 1200 cc injectors ran 9.04 at 159.64 mph, the car weighs in at 2950 pounds with driver. Figure it out from there. How many of you are going to trap 159.64 mph? No offense but not many, so that says a lot for that fuel system and it's dead simple to install. NO cutting into your factory wires or car at all!! This was at 635 whp on gasoline, duty cycles in the 9X% range.

My car is now running our double pumper with the same modded pump, twin feed line kit and our BR rail. I have done testing with an SX regulator and it did NOTHING at all for the fuel system. So I am sticking with the stock regulator, no need to change it. My car is now on E85 and 2200 cc injectors. I have datalogged the fuel pressure like this and there is a thread here on EVOm about it. The car is now at 710 whp and duty cycles are in the 87% range. There is NO, ZERO, NADDA fuel pressure drop off at all. That means I have plenty of fuel pump and fuel line left.

According the calculations from the fuel pumps being flowed, fuel pressure I am running and the fuel lines the fuel system is good for over 1,000 hp and I see no reason to disagree with that based on my car and what I am seeing.

No offense to anyone but the bottom line is you have to be a fool to put a fuel cell in the car with AN lines and loud external pumps.

 

FWIW I'm seeing 90% IDC on e85 with FIC 1650cc injectors and buschur twin walbros at 717awhp (dynojet) stock fuel lines, stock regulator and buschur fuel rail.

However, I don't like these injectors, the car runs like *** unless you're WOT. I'll likely be looking into the injector dynamic brand asap.

 

We have them instock Mellon, the 2200's are just flat out excellent.

 

OK so dave your saying for my needs i just buy your 500 dollar kit and call it a day complete install of everything i need and im not shooting for anything more then 650 to be honest heck i just wanted to surpass 500. if thats the case ill be ordering one next month then after i get this 2.3 shortblock in with mikes built head redecked/cleaned ready for action. Mellon also are FIC injectors better then PTE?? i was told they have a better spray pattern. whats the deal stick with 1000cc pte or change brands as i have some on lock but have not pulled the trigger yet

 

rockmanx, yes, absolutely for 650 whp all you need to do is put the standard double pumper in and I bet you can get the on the 1,000's, if you didn't buy 1,000's go with 1200's. I would say it's worth the money to put a fuel rail on the car too.

David

 

Yup a straight answer yes im building or rather have been building this motor from scratch using new parts etc with advice of mellon and some others to get it right. im not trying to run 9s but i want a strong motor that could if i WANTED TO go up in power with turbo upgrade and i will not have to worry about adding more stuff. i got already a perrin fuel rail and ams replacement fuel rail line. so i got that covered. i got a killer deal on 1000cc injectors PTEs but have not pulled the trigger yet as i was informed about FIC injectors. whats the true deal on those David?? I was also intrested in the double pumper but was confused by mikes site as to which one to get.

p.s. i still need that ported gasket for my buschur throttle body i never got lol.

 

Rockman, the only reason I went to FIC 1650 was because i was afraid the PTE 1600 would be a little small for my needs. I tried the FIC 1850 first but they require a 16v system, the 1650 are supposed to work with 12v but it's a bit sketchy in my opinion...rough idle/cruise especially on 93 octane but WOT is beautiful. My car is a daily driver so that just isn't acceptable to me

 

so your telling me to stay with our orginal plan of PTE 1000cc and throw the FIC 1050 out the window. I just need to know to pull the trigger or not lol you know our goals with this car soo what have you. so the better spray pattern does not mean anything??? how goes the goal of those 9s this year almost over hommie?

 

1000cc work great for daily driving and weekend warriors, once you get above that, you start giving up a little of the stock feel in my opinion.

pte 1000cc or fic 1050, makes no difference, they are both very good injectors.
