Yeah, definitely don't wanna start losing pressure up top "trying" to push a single pump. Will keep a close eye on IDCs when I start to dial E85 in. May end up just biting the bullet and get a double pumper... Thanks for your input.

You could always look towards a Walbro 400 instead of a double-pumper.

I agree with Kracka.

Coming from a guy with a double pumper, if you can avoid using two pumps do it. However i view the Boost a pump as just as reliable (or unreliable depending on how you look at it) as a twin pump.

My next upgrade will be a big *** weldon, external style.

Thanks for everyone contributing as well, And nice results megatron, that was at relatively low boost for an EF4, Im sure if you want more power you will find it.

Thanks for starting this thread as it has gotten a lot of folks (including myself) excited about the EF series!

I assume your talking about the E85 version of the wally 400? Is that what their calling it 450?
Thats what i am running currently i got it a few weeks ago after it was released.

So far supporting low 500WHP range on stock rail, lines, wires, regulator. I havent tried high boost on it yet.

This sounds scary, my friend.

I like simple set ups. If the larger single can get me there, count me in.

Correct, which is why I won't be getting them

No cams and no lightweight flywheel this time around.
