Not even ten years ago, finding a 1,000+ horsepower street car idling happily at a stop light was a rare and magical feat. These days, if you aren’t approaching that power mark, you just aren’t trying hard enough. DeatschWerks has realized where things are headed and decided to release its DWR2000 pressure regulator and -8 AN fuel rails to fill a need on a quickly growing segment.
So what’s new from the DWR1000 to the 2000 you ask? Lots, including, and perhaps most importantly, now being compatible with E85. It is also now capable of feeding 750-2,000 horsepower—no small task by any means.
“Compared to the R1000 the 2000 is larger dimensionally,” said Chris Mills of DeatschWerks. “It has a -10 AN inlet and -8 AN outlets. It also has several ports on it, in case you want to run a gauge directly off and it is vacuum referenced.”
The regulator also features a stainless steel ball valve as well as all stainless steel internals. The rest of the unit is hard anodized, making it more than compatible with ethanol. A ball bearing adjuster ensures precise and constant adjustment in any situation and a fiber reinforced Viton diaphragm will keep the go juice at the appropriate pressure for years to come.
“When we released our new -8 fuel rails, it didn’t make sense that the regulator (DWR1000) was still a -6 AN output,” Mills said. “That lead to the new regulator having -8 AN outlets and being capable of supporting more power.”
To help you plumb your newly improved, high-flow fuel system, DeatschWerks has also released more than 150 fuel specific fittings, ranging in size from -6 AN all the way up to -10 AN. They also introduced a new set of matching AN wrenches to make installation a breeze.
“In applications that are clearing 1,000 horsepower, a -6 line is just not going to cut it,” Mills said. “That’s why we bumped everything up to at least a -8.”
Mills also mentioned that DeatschWerks is frequently looking to improve its offering of E85-compatible components to meet the growing demand for such products.
In the fuel rail department, DeatschWerks will be adding 16 new part numbers to fit everything from an LSX to an RB26. Specifically in the LS realm, they will offer the LS1/LS6 style as well as the LS3/LS7 style. All rails are extruded and anodized, meaning they have no need for adjustment at any point and fit right the first time, every time.
“The bore on the fuel rails are 18 mm on our domestic stuff, which is quite a bit larger than stock and our competitors,” Mills said. “They’ll be able to supply a lot of fuel—whatever fuel you want to run, it can handle it.”
He continued, “One of the really cool things is that both rails will have two 1/8-inch NPT fittings on each end, so if you want to run a fuel gauge, or tap into the fuel for a nitrous setup, they’re there. It also allows you to decide whether you want to run a return or returnless system, cross it over on the front or back—it’s just a really modular system.”
If you’re looking to make the switch to E85 or just want to upgrade your stock fuel system to be able to feed more ponies, the new gear from DeatschWerks is definitely worth a gander.
