Dorch Engineering B58 Gen2 DS3 HPFP Upgrade **NEW PRODUCT**

[Extreme Power House]

The Dorch Engineering B58 Gen2 DS3 HPFP Upgrade is the highest-flowing single-pump solution available, delivering 20% more fueling capacity than the DS25. This OEM drop-in solution offers full DME control, no modifications, and an effortless plug-and-play installation. Designed for extreme performance applications, the DS3 HPFP supports up to 1150whp when paired with a 27% cam upgrade, making it the most powerful fueling upgrade for B58 Gen2 engines.

NOTE: If you already have an ethanol sensor in your car, simply choose the correct chassis fitment and type “ECA HOSES” in the order notes.

Better than ds25 for OEm injectors?

No. You can easily max OEM injectors on the ds25.

Thanks bro

DI has been on the up and up, and I’m here for it. With nostrum coming out with insane DI injectors that could do 830whp with a ds25, I’d be curious to see what numbers come with this pump.

Any word on when the new injectors will be released by Dorch?

Goddamit dorch, i wish i waited ??. I have the ds25 pump and s58 injector combo and i'm now wondering should i try and sell it to move to the ds3? 20% improvement over the ds25 is not a small % bump imo. Basically this all means more boost.

What are you planning on doing @razorlab ? Are you sticking with the ds25?

I'm sticking with the ds25 for now. I'm already able to get my trans to slip so I need to bring the power down a little.
