LG A90 Supra Auxiliary Fuel Pump Kit

Camus · Jun 2, 2020

Hi, does anyone knows more about this kit?

https://www.lgmotorsports.com/lg-a90-supra-auxiliary-fuel-pump-kit.html

It was posted on a YT video of a Supra vs C8:

How it works?

Thanks.

I know our stock fuel system maxes out below 500 who on pump gas, it would be good if someone found a simple solution to the maxed fuel system.
On the other hand, I doubt an aux fuel pump (without additional injectors) can do any good as we already run very very high pressures through our mechanical pump.
These C8 vettes are fast

This should explain it all :popcorn:

Saw this kit as well. Looks pretty sturdy. A fellow member here actually installed one recently. They also have a YouTube channel as well goes by the name Lite Brite. Will put a link to the video.

Very interesting, thank you for the insight
Let's see who breaks the high pressure limits.

Moreover, I'm more interested in an upgrade that can take me on 93octane beyond the limits of 500/550whp without the need for Methanol / Ethanol

The stock fuel system is good for over 600HP on pump gas. The stock system just struggles down low on ethanol rich fuels since the fuel pump capacity cannot flow enough as it is mechanically pumped.

I'm almost maxing out my injectors duty cycle running 93octane @ 19PSI on the stock turbo. Specifically in the 4K/4.5K RPM range.

PSI is relative. Absolute numbers are a more accurate comparison.

I run am able to make plenty of power on e50 with the stock fuel system. And in 91/93 I am typically octane limited before fuel limited. The fuel flow is limited in that rpm range. But there should be sufficient for pump fuels.

We installed it on 2 of our shop Supras.

These pumps are known to flow for days!
