With the YouTube BBCode, you only need the ID of the video and not the entire youtube URL.

The URL for this video is https://youtu.be/aHXMTzenVTg
All you need for the embedding is aHXMTzenVTg

BTW, I send you a couple of PM's =) Might be easier to communicate over email? I am ready to order stuff tonight =)

With yours and other people slightly lower daily numbers, I think I am going to get a couple hundred cc bigger injectors, the twin pump setup and maybe push for 700/550 on E85. The last dyno run I did for seb to get the ecutek controlling my boost solenoid was 620/550 at 14psi on my high setting. I dont want to go crazy on this stock bottom end but that would be a nice thing to say im able to change a map and be at 700hp for dyno outings and the occasional Mexico trips.

Side note, the RE-11 305's aren't cutting it at the 620/550... whats the next step for daily tires with some rain ability? Or am I in the brake change and tire change column if I want to use this power now?

Thanks Justin and congrats man!!

But in your case you would still have to play with the hoses to get an inline filter into the system. :(


I have the same question, when I ordered my kit I did receive the external filter with my kit that I installed under the frame rail cover and you helped me initially during my order to find a way to install my EC-2 flex fuel sensor over the fuel hat with provided fittings about a year and a half ago I guess before the "E" kit was a thing?

How easy would it be for me to do the new hat, new twin pump, and rails? And would this be sufficient for big built motor power in the future or would I need larger lines and other things than that which came in my s1(.e?) kit?

Thanks Charles,

Lol, I have basically the same numbers and tune from Seb, 610/560. At that power level no summer tire is going to do any better, no even ps4s's which would be the only other street tire I would buy. If you are going to run at 600 plus whp, you got learn how to contol your right foot and make sure you got heat in your tires before ripping out on the hard top.

Great job Charles, Seb was pretty excited about your collaboration on this project. Awesome stuff that is going in the Z community.

If you have the external filter than you already have the S1.E kit... as far as our fuel system acronyms go, the E means external filter and that is how we distinguished it from the previous S1 kits.

You wouldnt use our billet hat with our twin pump, it would be one or the other since the billet hat is for the stock fuel pump housing and the twin pump has its own hat as part of its design.

The twin new pump can be configured to use a single -6 output, and factory style QD return... which means it can be used as a drop in replacement for the stock fuel pump module so long as the car has an external filter already, as the twin pump does not have room for an integrated filter.

Adding the rails would mean switching from your S1.E to our S1.SE kit. This entail purchasing the rails, the rail crossover hose, and the rail to regulator hose. The rest of the S1.E on your car would remain in place as they are the same parts.

Hey Phunk, What all would I need to do a return system and twin pumps? This will be a new upgrade. I am stock at the moment.

phunk 01-18-2018 07:15 PM

When used with our existing S1.E and S1.SE fuel systems, you can just add the twin pump. Nothing else in the fuel system needs to change. This spring when we start putting Justins Z back together with the built engine we will make some larger hose upgrades available for maximizing the twin pumps output, but it will already support most likely 1000whp with no issues as is.

If the car has one of our older fuel systems that does not include an external filter, most of the plumbing will need to be replaced and a filter added.

What 2 pumps will I need for E85 and a max goal of 800hp?

phunk 01-18-2018 07:40 PM

You could use a pair of Aeromotive 340, or a pair of Walbro 450... DW probably has some pumps that fit, I need to get more familiar with their product line one of these days. You can even mix and match, like one 340 and one 450, etc. 800 isnt a lot to ask of twin pumps since a single 450 can typically take you to 700whp with our high compression and relatively lower max boost engines.

I would highly recommend picking up a Hobbs switch to activate the second pumps relay in boost only... so that you arent pumping 1200hp+ of fuel back and forth just to idle and drive around.

Is someone planning on boost? :confused:

I have been planning for over 2 years. LOL Time to stop planning and start doing.

Spooler 01-18-2018 09:25 PM

Guess I need to go with a single to start with until I build the motor at a later date.

Congrats guys... Love it at the end... "Stock...Not looking good though" guess we know what the limit of the half shafts are now.
