Which in-tank fuel pump??

[Sweet6]

I had stock lines, 255 liter pump 93 and single nozzle alky with 60lb injectors. Went 10.57@127 at 90% DCs. 3650lbs raceweight.

Sorry to hijack or resurrect an old thread but I figured it might be better than starting a new one: I'm looking at upgrading my fuel pump soon. There's an upgraded in-tank pump and hot wire kit from the previous owner but at this point the pump is 20 years old. Things have come quite a way since then. I'm looking to run mid-10's max and I'd prefer to have safety buffer. Ideally, I'd prefer not to modify the return line if possible.

The DW pumps seem to be the way to go unless something have changed? Currently running 60 lb injectors, a TT chip and stock turbo on 93 octane. In the future I plan on going Alky and a turbo upgrade. Any guidance? Thanks again, did some searching but the majority of the threads are 10+ years old.

The DW300 will work well, cheap, and easy install. Will go at least mid 10s with alky and the 60lb injectors.

Did you have to modify anything?

Injector time

With a recent turbo upgrade, I have realized its time for another step up in injector size. Currently have 50#s on it. So the question is do I go 60# or 80#. I am going for a solid mid 10et this winter (hopefully). Any feedback on this is appreciated, especially the guys running the 80s...

It is possible of you work closely with TT, and have the fuel pressure in the chip programmed to a higher setting.

If you go to the ECU-GN, you will have full control and can PW modulate the pump, change pressure setting, or fuel pressure compensate in the ECU.
Lots of options to get it right, pending the setup and your strategy.

I appreciate it and will look it over. Unfortunately that’s the case with so many threads these days.
