V1 CTS-V fuel pump assembly question
Can someone tell me if this is what the stock V1 pickup assembly looks like?

So I am guessing that means there is no simple drop in fuel bucket upgrade like the V2 or the 8.1 the GTO guys are using?
Im worried that an upgraded pump or BAP is going to cause cavitation because the volume of that bucket is not much.
Im putting in an LS3 with a TVS2300 at 8lbs of boost and a custom boost cam. Were guessing between 550-600 HP which will be about 700 at the crank.

GSS342 drops right in the bucket. (identical size)
Go with two, some plumbing, hotwire kit and you would have no problem sustaining 600rwhp.
I would highly recommend to change over to a return and add a FPR on the rails... The pressure varies when your using the regulator in tank...
Several guys with WS6's and such have the same issue.
12-916 Is Holley equivalent
You can also use A Denso 19513-1270 - BUT realize these draw DOUBLE the current.
You can also go with Kyosan 895091-0810 which is a modified Denso (toyota pn 23221-46110 equivalent) Also runs double the current - quiet and is larger so modification of the bucket is a MUST. also flows a hell of a lot 390lph @14V @ 43 psi. hotwire is a must.
I would run a cheaper walbro w hotwire / twin if you think its needed, they are still quiet enough, no bucket modification and run at 65psi - boost referenced... you will not have any issues.
You could still run the BAP on a pressure hobbs switch... but I doubt it would be needed.
Aeromotive 340 is another option... I dont know much about them though... size / current draw etc.

I ordered the racetronix kit and have looked at the pumps. I didnt know the GSS was an idenitcal fit. I will probably go with that one.
My concern though is that small reservoir (sump) that the pump is in. When using the extra fuel required at WOT, how does that thing not empty and overheat the pump or even worse cavitate?

I'll try and take some pictures today.

If I go with anything more Ill do a return setup (w) external pump, etc. etc. I just didnt think it was necessary for my goals.

In the process of running a magnafuel 4301 setup. Just pulled out the sock stuff and capped everything. Sumping the stock tank on both sides towards the rear.
For 700 horses though, the stock lines might support it. Will be getting close.

I ended up going with the DeatschWerks DW301 pump. I sent it in to be flow tested in our stock assembly.
I am attaching the results of their pump in our assembly vs the stock pump. As you can see in the results the stock assembly is very restrictive as this pump flows 300lph at 56psi unrestricted
