google brought me to this thread I'll see if you reply. Looks like some guys are still on the boards lol.A 340 is way too much for you and you really won’t take advantage of what the 255 has to offer either. If you’re gonna upgrade, might as well get at least a 155 though. Some extra fuel won’t.
On that note, a good fuel pump is like $90. Why skimp on a crucial part that keeps your car operational? The tre performance are decent pumps for the price, I think they’re like $70.
a few dollars more than what? I need a 340 as the 255 will not suffice for a blower setup making over 500 to the wheelsA walbro Gss340 (high pressure 255lph pump) is only a few more dollars and will support pretty much anything that can be run on a stock fuel system which maxes out just over 500rwhp. Which i'll assume is what you are doing since these pumps are made to go in the stock hanger.
well I've had quite a few folks use it with the stock hanger and even without upgrading the wiring, ( one of them on a fox) and no issues.....I personally don't see the point in a pump that size on a stock hanger.
Unless you have a dart block and a complete fuel system, i don't see a point in a true 340lph pump. And you if you do have a dart block and a fuel system you wouldn't be using the stock lines and hanger.
You would be using something like this:
Aeromotive Mustang 340 Stealth In-Tank Fuel Pump Assembly (86-97) 18638

All of these things I know lol. I know the difference between the two pumps as well. I also know that when you say 42's and the 340 good to 500 HP it's different from Na to boost correct? Sure is better to be safe overall but there have been people running up to 5:30 5:50 keeping the RPMs below 6K and their engines lasting. Plus I'm not one that I'm not one who dogs their car matter of fact I baby them a good bit for the most part.My point wasn't that you can't run that pump, it was that it doesn't make sense to on a stock fuel system.
42s and a gss340 have been run successfully for a lifetime up to 500rwhp and if you go much further you need the entire fuel system, not just the pump.
To be clear the Gss340 is the high pressure version of a 255lph pump, they are NOT the same.
The block doesn't even support 500rwhp reliably.
If this is for a real 94 cobra with an original 2 bolt main shortblock I wouldn't be going anywhere near 500rwhp. I'd stop well short, splitting a block is a catastrophic failure that could cost you 10 grand to fix, all so you could brag to your buddy's that you make over 500rwhp, when in reality on the street you couldn't tell the difference between 450 and 500.
More boost ,that's how!Always makes me wonder how these evos and civics and 2jz’s and bimmers make 1,000 horsepower and we have built v8’s with H/C/I plus boost making 500-700hp.

Its actually not running now... Its about 11 years old, the really old metal bodied ones were supposed to be the best ones...I'd sell that POS while it's still running and try finding one made in the US and built by the same company that pooped their label onto it.
I wonder if any still exist.
