Fuel Pumps: Ford GT vs Focus vs Cobra vs Walbro 255HP

[tmsoko]

Does anyone have a pressure / flow chart or any specs at all to compare the Ford GT, Cobra, Focus, and possible Walbro high output 255 fuel pumps? I currently have a Walbro and trying to decide if I add another, upgrade to a pair of the factory Ford pumps everyone is talking about, or just put an external Aeromotove or SX pump in.

My engine is a 351W with AFR205 heads, custom headers, and a 2.4L Autorotor supercharger with custom adapted '03 cobra water intercooler system. Shooting for 600+ Flywheel (since I am running a stock block). Down the road will be Dart block and max out the 2.4L boost.

I just can't find any real detail on these pumps other than "you should upgrade to Focus SVT or Ford GT pumps". I need to know what they flow to choose best fit for my app.

Thanks!

**Edit: Not realy sure what happened to this post, but I was just referencing some amterial found on the KB website which did a pretty thorough comparison of dfferent pump setups. In a nutshell, the stock pumps with a BAP outflowed all other pumps with the exception of the GT pumps.

Note sure what IronTerp is saying!

Anyhow, I used the chart I found on Mod Fords and converted / added Aeromotive and SX fuel pump detail to the list. The Dual GT pumps blow even the Aeromotive Pro-Series pump out of the water (by ~25%) and that pump is rated at "1400HP" for supercharged apps.

Am I missing something or is the switch to Dual GT pumps massive overkill? Just seems like a whole lot of fuel would be making the trip around the fuel system and picking up alot of excess heat!

How expensive are the GT pumps?

How is that so Terp? twin Aviator and Focus pumps with a BAP will support more HP than stock twins with BAP?

This is misleading Walbro makes an assortment of pumps for Mustangs of all years:shrug:
The traditional Walbro 255's aren't designed for returnless fuel systems they'll burn up!
