Current Fuel Starve Options?

gomer_110 · 10-05-2022, 07:28 PM

I had planned on buying the CJM road race fuel pump system to address the terrible fuel starve these cars have and found out it's not being offered for sale anymore. Has anyone found any alternate solutions to the fuel starve issue that work as good as the CJM option did?

Did you get a hold of phunk directly?

Look at the Radium stuff. They have something.

CJM has a fuel starve solution but its currently only available for cars with a return fuel system, which can be unnecessary added expense in cars that dont have big HP upgrades.

For strictly fuel starve solutions that are compatible with otherwise stock fuel systems, there is the simple Z1 kit, and then there is the Radium kit which works much like the old CJM RRP kit plus a couple enhancements.

Try upgrading the fuel pump first. Just upgrading the pump to a stronger aftermarket unit has me running down to 1/4 tank on track, before it was 3/4 tank starving.

I thought Phunk was working on a new setup, but i haven't seen/heard anything since early in the year

I have the Z1 fuel starvation kit, (bought it from fryzia23)
I have had excellent results, I actually ran out of fuel at Barber Motorsport Park.

You’re not driving hard enough

I have used both Z1 fuel starvation kit and Radium surge tank.
Both can fix the issue. The Z1 kit is a bit difficult to install because the fuel line is in the fuel tank, which might interfere with your fuel level sensor and cause inaccurate reading. The Radium surge tank is a bit better especially if you are considering to upgrade to dual pumps or having dynamic fuel pressure according to vacuum pressure when boosted.
