Thank you all for the information. It made the process a little easier for me. I've ordered the 340 pump, ground wire kit, and c5 filter/regulator. If it will handle around 750 to the tires, it is sufficient for my needs. I have plans for this weekend due to fathers day, but I intend to install the kit the following weekend. Dragula, i'll do a follow up after the install. I'm hoping it goes smooth since it says direct bolt in kit.

So I started my install today. I"ve been super busy with work, vacation, life. You know how that goes! I used a write up on here to drop the tank an inch and lay out the hole for the access door. I learned that in a convertible you have to get some of the fuel out of the bucket to tilt it. I don't have the clearance to raise it straight up like a hatch car. I laid everything out on the table and i'm missing a few things from the kit I bought. I contacted WS6 store and they sent it out today. I managed to fish the hot wire harness up from the bottom of the car and into the new access hole. That was my stopping point. Tomorrow i'll run the hotwire harness. If that goes smooth i'll start the C5 regulator kit. I'm in no hurry, just taking my time

So how good is the 340 in a stock bucket?
Do you have to modify it to keep fuel in the bucket?
The racetronix kit keeps fuel in the bucket with the way it’s made.
im just wondering when I go turbo if the 340 in the stock bucket will run Dry?
What hp level is the 340 good up to with e85 in a boosted setup?

It fits nearly identical to the 255. We engineered the c5 filter regulator kit to return more fuel into the bucket so the bucket never really runs dry. It doesnt fill like the 255/venturi setup but it does still work.
The 340 kit will handle more power on E85 than the stock lines can flow with proper operating voltage. We say roughly 750 though on stock lines as that is pretty much where they max out.
Above that we recommend the line kit from racetronix. Then youre looking at roughly 800 for a single 340 depending on fuel demand, inj size, and target afr.

So help me or us understand, what’s the difference from the stock, racetronix 255 and the 340 kit when it comes to fuel getting into the bucket?
i thought the stock bucket has a few small check valves to let fuel in but not out.
Do you have to modify the bucket for the 340?
I thought I read the bucket may run dry or not fill up initially to actually return fuel into the bucket.
Or will the bucket fill like stock pump does?
On a hard run, with a 340 pump, do we need to have the tank a certain amount with fuel so there’s no starvation?

Hopefully I am making sense here

The 255 kits with venturi use the venturi setup to pull fuel into the bucket and fills it up higher than the outside level because the bucket is a sealed design.
No other aftermarket pump has that. it also relies a little on the drainback from the fuel pressure regulator.
Since we still want to offer filling the module up and keeping the pump supplied with fuel, we ditch the factory regulator and housing and use another nylon fuel tube to direct fuel back to the pump directly.
So far i have seen no issue with running the setup like this on a few builds and no issue with keeping it above a certain level. it is a very good idea to keep it above 1/4 tank to keep the pump cool and supplied anyway but not a mortal sin not to.

The other guys will sell you a 450, pat on the back another satisfied customer and not give any provisions for return fuel or the fact that they are overpowering the factory regulator and flimsy housing

I have yet to assemble the bucket. My kit was missing a few things. I'm STILL waiting on my fuel hose that goes from the fuel pump to the top of the bucket. I keep getting the short hose sent to me that goes on the barb where the fuel pressure regulator was. I'm waiting on my third package from them now.... Hopefully it will arrive in the mail today.

I got the system installed. I did a before and after fuel pressure test. After I got the new pump installed i had about 80 psi. I called WS6store. they sent me the newer/better version of the c5 regulator. After swapping it out i had 60 psi. I notice my car starts faster now. I have put about 400 miles on the car and nothing bad has happened. All in all it was a very frustrating experience. Thank God I have multiple cars. I don't know what i would have done if this was my only ride. I know they are a sponsor here so I'm not going to go negative. Just take that with a grain of salt. Its my opinion. THE KIT WORKS AS IT SHOULD.. The main purpose of this kit is for my d1sc kit. So, i can't tell you what rwhp the 340 kit is good for yet. I'm close enough to black friday i'm thinking of waiting to see if i can catch a deal on a short block. .... I see thompson motorsports has a deal on a 408 for 3999, but i don't want an iron block. I like the black friday sales. the companies compete and our consumer dollars go further.
