that's the point of the sump, so you can get rid of the in tank single walbro. no feeder pump, the large pump draws right out of the sump.

supra guys just tap the bottom of their fuel tank, thats all we'd have to do. You'd keep the buckets, so your fuel level senders wouldnt be affected and you'd return the fuel back thru the bucket as well, just like it is now.

interesting.

sounds like a good setup. Wonder why nobody put effort into that? Couldn't they use the second tank top and make an adapter so you wouldn't have to tap the tank? That way it's a bolt in piece.

BUT, that would mean sucking the sludge and filth in the tank

you could do that as well i think. Obviously someone like Phunk would have a better idea on how this could be done.

theres just little interest as a community to go with that kinda fuel system. twin pumps are enough for 99% of the cars on here.

just a FYI, the driver and passenger baskets use the exact same fuel float. SO you could make an easy triple pump setup by just using the stock basket with a 250LL and attach the fuel sender to that. That way you'd be pumping out of both sides of the tank.

Should have some nice tech info about our new pump to post early next week. We've gathered some good data this week and should have some time over the weekend to put it together.

Here's a bit from the first round...

Hmmm me likey... for those who are stock block FI and want to run E85 without twin pumps (me!)

DeatschWerks: How many different models/applications of your pump are you planning? please contact me at the number in my signature if you have any spare time, id like to see if you have one on the way that will be compatible with our twin pump assembly.

So, what is the WHP limit with this new pump in our cars?

BUMP

Any update on this?

Chris@DW

Right now, the DW301 is going to be the workhorse.

I can see us possibly doing other fitments and lines in the future, but for now we want to focus on getting DW301 off the ground and established.

Thanks for the question.

Hello, Just wanted to let you know I got your voicemail!!

DW and I did get in touch last week. For now, there will not be a DW pump that is compatible with our twin pump. I believe they are considering the application that our twin pump requires, but havent moved on it yet. We will see what the future holds!

Bummer that we'll have to wait a while for that.

A CJM twin pump assembly upgraded with either a version of the DW301 or new Walbro 325lph pump would be an attractive option for those of us trying to push 700+whp on E85.

phunk

iTrader: (21)

Well, in terms of 700, I think you are no problem... I *think* you should be able to run just over 800rwhp on e85 with it as is

RudeG_v2.0

iTrader: (1)

Cool! That's significantly more than I expected!

phunk

iTrader: (21)

well, i suppose it depends on the dyno type. but I would be insanely shocked to see our twin pump as it stands run out before well into the high 700s rwhp on a dynojet... but without having done it, i cant say for sure.

ProEFI uses a Dynojet and I still plan on doing a C16 tune too. So I should be fine... for now.
