Thanks for pointing that out! It was a joke...

Here you go OP. This will probably fix it.

Multi-Pump Fuel Surge Tank

The fitting only seals to the bulkhead with 1 oring and just one of those slide on metal clips so I was a bitch sketched out, but no fuel sloshed out while corninger at 1.6g with a full tank of fuel and hitting a big enough bump to but the car on 2 wheels so its seems ok.

Super-mega derail: Why hasn't an SSM guy purchased my freaky-light carbon top yet? It would make the wing work significantly better.

Leafy

iTrader: (1)

Yeah, a top is on my to buy list, its not high enough up yet to drop that kind of money on right now. AND I'd probably have to remove the 2nd element if I made the wing work even better, everyone who drive's my car asks if we can turn the wing down because it makes too much rear downforce. I just repeatedly yell there's no such thing as too much downforce (and occasionally throw in a line about doing canards) until they quit complaining.

This thread is all about the derails now, at least until OP shows up and gets us back on track with more data...

Leafy: Y U NO RACETRONIX LINK IN BUILD THREAD?!

...but thank you for confirming the part.

I like that the fuel pump looks like a Fleshlight.

That's how you know it will satisfy your needs. Every time

No new data yet. Waiting for injectors to show up. Thinking about the above fuel pump and wiring kit with all other options to go along with injectors. This being said because everyone is telling me the dw300 pump is crap. Guess I'll replace it while I'm at it.

The DW300 is a really good pump, its just not in the "I want 500whp on E85" club.

Its like saying that a GT45R is a bad turbo. No, its just the wrong size.

Right. I've been running a DW300 (the old 320LPH version) since I built the car 3 years ago. It's quiet, Ethanol compatible and draws less amperage than my old WB255.

The last couple of my DW orders have had the new 340LPH rating it's certainly not sized incorrectly for a 500hp crank car.

"DeatschWerks redesigned the DW300 to offer greater flow with no significant increase in current draw. The new DW300 pump flows 26% more at its peak and 20% more on average. The low amperage draw minimizes pump temperatures, maximizes pump life and reduces stress on OE wiring.

The increases in flow were specifically engineered for high pressures (60-90psi), where forced induction applications need it the most. Conversely, fuel flow has been limited at low pressures (30-50psi) to minimize heat generation in return fuel systems. This dual zone approach results in a flatter flow curve, which maximizes both performance and reliability for supercharged or turbocharged applications."

How much does it flow for a car running 60psi base pressure at 30psi of boost? Thats 90psi total.

DW300 @ 90psi - 255LPH (15 amps)
Aeromotive 340 @90psi 205LPH
DUAL 255 WB pumps @ 90psi 234LPH
WB F90000267 AKA400LPH AKA450 AKA485 @90psi 252LPH (18 amps)

I've seen a number of results on the WB e85 pump 252-268LPH

They must have changed the DW's chart since the last time we all looked and agrued in soviets build thread about how it doesnt possibly flow enough for a high powered turbo car because the flow tanks at high pressure.

FAB

They did with this new revised DW300. If there marketing team was thinking, they would have rolled it out as an entirely new SKU. Once a product gathers an image in this industry it's nearly impossible to change. I also think it's silly they call it a DW"300" for a 340LPH pump and a DW "200" for a 255LPH. I have a hell of a time explaining that to customers.

Update:

Injectors are in and intercooler is mounted. Intake temps are now where they should be at 20deg above ambiant. Injectors are handling 93 octane just fine. I still have finish tuning it on 93 first. Then I can figure out how the 1300's will do on E85. I'm guessing just fine due to all the posts.

That is a BIG change for the DW300 pump. I like. I always liked the DW300 because it literally drops right in (vs hacking things up for F90000267).
According to the new numbers, at 100psi and 13.5V, DW300 flows more than F90000267

I know I'm late to the game but I just wanted to throw out there that we've (race team) been running ID injectors at 100 psi for ~2 years and we've never had any problems. We also saw a significant benefit going from ~75 psi up to ~100 psi on a naturally aspirated car.

If your afraid of running 80 psi on EV14 injectors, don't be. As long as your fuel pump and other ancillaries are up to snuff, the injectors have no problem living at 100psi.
