Alright guys, I am wanting to get back into E-85. My budget is low right now, but my ultimate goal will be in the 450-500 <---- Absolute max Awhp range. with cams and an FPred (or similar) style turbo. As of right now I'll just be running the stock turbo, with bolt-ons.. Looking for 370ish WHP.

My question is which fuel route should I pick? Remember the cheaper the better and if you have suggestions please let me know.

AMS 600hp fuel kit... Adds a Walbro inline.. says good for 500whp on E85.. which would be my limit.. Cost is $400...
http://www.amsperformance.com/cart/a...-fuel-kit.html

Next choice would be just a drop in walbro with an install kit.. (any suggestions?)
basic price is 230-250 range... but would need something more for later on with the red..

Or last the Buschur Racing double pumper kit.. Two intank walbros.. the best solution, but the most expensive at $500.... maybe overkill?...

So let me know what you would do or any other routes.. Thanks

 

I prefer BlaqOPs but the pricing is the same as Buschur. They do have a single kit if you go that way.

Honestly, if you aren't building your block then you might just want to go with a single pump and stop when that maxes out.

 

Drop in a single pump for now or spend the $$ now so you dont spend it later and get the buschur double pumper good for as much as you want to make... Buying the AMS kit that stops at 500 doesnt make sense to save 100.00

BlaqOP's is a little more $ I believe than Buschur, plus buschur is already pre-made etc.. and I prefer buschur period.. just a matter of if I need it.. I'm just trying to keep costs down as I plan on going to Buschur this summer for clutch, cams, turbo, tune, etc.

 

Where can you purchase the BlaqOps set ups? Also not to steal your thread, along the same lines. How much power will the DW injectors at 800cc support w/ an E85 set up? Anyone have a calculation on fuel set ups? I had one for #/HR but I don't know any for cc/HR.

 

Nope. The Buschur is equivalent to the lower price BlaqOPs (uses a Hobbs switch). The Buschur also does not come with an inline filter or new lines for under the hood...you'll have to take care of that on your own.

Not sure what you mean by that...they both require you to send in your stock hanger as a core.

Google the name.

320 on the dyno that I tune on...a little bit less than the stock turbo is capable of, in other words.

 

320whp? for the 800cc injectors?... I've seen 370whp from the cobb off the shelf E85 map with a single walbro and 800cc DW injectors.. I think they did a custom tune and squeezed another 5hp and 10-15 wtq..

Anyhow, I'd say thats about the limit for the injectors.. Anyone know what the limit of a single walbro fuel pump is on E-85?

 

A higher reading dyno. Does every single thread on the forums have to devolve into a dyno debate? I mean, really...I said you won't be able to max out the stock turbo and that's a fact. On high-reading dynos you can hit 400 on a stock turbo w/E85 and cams.

You'll run out of pump before you run out of 1000cc injectors. In the vicinity of 500hp on a high reading dyno.

 

I am in the same situation, I am looking for a fuel system setup that will get me between 400-500hp. I think a double pumper would be over kill plus I cant afford the down time. Far as injectors I see most people are going with the DW1000 but they are not making those anymore so whats the next best set?

 

You might just want to go with something like the AMS inline kit (no downtime) and some FIJ 1100's. The DW's in 1200-1500 sizes are in beta testing with various tuners...if you live near a big-name tuner then they could probably get them for you.

 

I have googled the name, searched the forums, ex........... I still can not find their website or anyone that sells their kits.

Hope this helps... should get you in the ballpark for the setup you're planning to run.

Fuel Pump Sizing
To achieve proper fuel delivery, you must select the right fuel pump for your vehicle. In most cases, where the engine has been modified only with “bolt on” performance items, there is rarely need for a larger fuel pump or larger injectors. Vehicle manufacturers typically design a “safety factor” into the fuel pump to accommodate the deterioration of the fuel system over time. This safety factor is intended to compensate for a fuel filter that is nearing the end its life, or for deposits in the injector orifice. Our research has revealed that generally there is about a 15%-20% oversize in most factory fuel pumps.
If the engine is enhanced via forced induction or nitrous oxide, the stock fuel pump is inadequate. If the engine’s power is increased more than 15-20% fuel delivery must increase as a factor of the power gain.
The way to determine the proper-size fuel pump is based on the desired brake specific fuel consumption (BSFC) of the engine. This term refers to how much fuel in pounds per hour (pph) the engine consumes per horsepower and is a measure of the efficiency of the engine. It is a useful term in determining the total fuel requirement of the engine.
On vehicles equipped with forced induction or nitrous oxide, higher BSFC’s are required as an added measure of safety to prevent detonation or high combustion chamber temperatures. Below is a guide of BSFC’s with standard CR that AEM uses for various engines that run on gasoline:
• Naturally Aspirated engines have a BSFC of .48 to .50
• Forced Induction engines have a BSFC of .65 to .68
Methanol (alcohol) powered engines require twice the amount of fuel so the BSFC’s are doubled.
Calculating the total fuel requirement of an engine requires simple equations that we outline in the following section. You must know how much power the engine is anticipated to make and we recommend that you guess on the high end. The fuel requirement will be determined in pounds per hour of fuel flow. Since most pumps are rated in gallons/hour you must know the weight of your fuel/gallon. (The vast majority of gasoline based fuels run at 7.25 lbs./gallon.)
The equations to determine your fuel requirement is as follows:
• (Power x BSFC) x (1 + Safety Margin) = pounds/hour
• Pounds/hour / 7.25 = gallons/hour.
An example of this equation is:
• 500 hp gasoline engine using moderate boost with a 30% safety margin
• (500 x .625) x 1.30 = 406.25 lbs./hr.
• 406lbs/7.25 = 56 gallons/hour.
• If the pump that is being considered is rated in liters per hour, use the conversion factor of 3.785l/gallon. The pump described above would be rated at 56 gallons x 3.785 liters = 211.96 liters/hour.
In the fuel pump sizing, always use a safety margin greater than 20%.

 

I just had the opposite happen to me this weekend. I wanted to see where my 1000 CC injectors would max at with my 6262. So before I did my pump tune I had Bryan tune my car on E85 with DW 1000cc and a single in tank walbro 255. We could only make 408 before the injectors were maxed. On my turbo that was only 20 lbs. The pump still had more in it. But we did stop at 98% duty cycle to maintain a buffer.

 

DW will most likely have the 1000cc back up after making a better spraying nozzle.

A double pumper and adjustable FPR with FIC 1100cc will take you as far as you want to go (500+ whp on ANY dyno) on E85.

Just keep that tank pretty damn full of E85 if you're taking it on road courses with long lefts...

 

Just a heads up, in case anyone here has missed the news, Buschur Racing now has cores for the EVO X double pumper setup. Here is a quote from their site:

"We now have cores available for building these, I have about 10 cores in stock. For those of you that can not wait to send your unit in and have it modified, you can now pay a core fee and we can send you out a double pumper. Then just return your core to us.

Thank you!"

So, anyone worried about down time doesn't have to worry any more. My double pumper went in the car yesterday and I am sending out my stock unit to Buschur Racing in the morning.
