FLYZNTN

Doing a Whipple install this week. Plans for this vehicle are to eventually go to a forged 416 rotating assembly but not until the fuel system is upgraded. I have looked at Fastlane, LPE and LPA and I came across the following note from one of the vendors:

"the fuel pumps supplied with the XXXXXX twin fuel pump kit are designed for use with pulse width modulated control systems like the 2010-2011 Camaro. For durability reasons XXXXXX does not recommend using the TI/Walbro gerotor type GSS pumps or other pumps not designed and tested for use in pulse width modulated applications."

I am looking for a little clarification on what this means and whether or not it is a legitimate concern.

Lastly, how about a group purchase?

Thanks,
Mike

Also, I have read an item or two regarding tank fuel levels. I.E., do not run below 1\2 of a tank or you risk a lean condition or excess heat build up in your fuel pumps. I'll just say up front that I am not particularly interested in a system with that type of stipulation. Any advice?

This may or may not be a 11101/11104 in a 2010 camaro tank

This is a "spy" shot so it's months out from being real. Just thought I would throw another option in the ring for you.....

I was looking at the Aeromotive Vette in tank setup just the other day wondering what plans Aeromotive had for the Camaro.......

Very interesting.

You guys want to borrow my car for a couple of weeks? All you have to do is leave the system installed when you give it back.

We offer the Lonnie's duals and it uses all factory GM components keeping 100% of the factory function. We have seen over 900whp with our complete kit. Working on some much higher HP systems as well.

These cars control the pump speed to maintain the proper fuel pressure.

The use of a non-pulse width modulated pump in this application may cause pump damage.

Also trying to eliminate the pulse width modulation feature is not preferred as you will need additional items for proper fuel pressure control.

I have a drop in dual pump setup for the 2010-2011 Camaro. It is designed specifically for pulse width modulated applications. These are in stock.

Feel free to call for more info.

Thanks for the replies.

Lonnie,

I noticed you offer the pump kit with or without the lines and fittings. This seems to point to a limitation in the OEM lines. What are the limitations of the OEM lines if you don't mind me asking?

We have seen a few cars over 750rwhp on stock lines, dependent on the engine configuration. Typically this is the power level that I suggest my fuel system upgrade.

Got it! Appreciate the informative responses.

Any issues with just going with a full return type system and an old school regulator? I don't see why so many want to keep that FMU in the loop. Am I missing something?

Actually there is no FMU per say. It is controlled by the factory computer & a pump controller module, which is a good setup provided you are capable or tuning it.

You can add an external regulator, but it requires special mods to the fuel system in addition to careful coordination with the factory pump controller so they do not fight each other, or cause the pump to run at full output all the time which will likely kill it.

My dual pump kit has already supported over 900rwhp, using the factory controller & regulator. We also have you covered if planning on higher power levels with my triple setup.
