We're just getting warmed up with Gen2 B58! There's been a lot going on behind the scenes here for the past couple years and some of these things can now start to see the light of day. Here's a sneak peak at our initial Gen2 cam offering. What's pictured here is a set that has been in our shop car for quite a while now. Just as we've done with Gen1 B58, we have a partnership with the best in the business @kelfordcams ! We can now bring you their full catalog of record breaking cam profiles paired with our upgraded fuel pump lobe. We also have a full billet "exhaust cam only" solution coming up just as we do for Gen1. As always, our advertised power numbers are very conservative and we let the 3rd party results speak for themselves. This +27% cam lobe is just the start and it pushes things quite far when paired with higher flowing injectors. Stay tuned for updated product pages, 3rd party results, and more product releases!

Gen2 B58 here we come! This one has been a LONG time coming, but of course with the release of our new and improved DS25-250 for Gen1, comes our latest and greatest creation, the DS25-350! This pump is completely reworked and optimized from the ground up to offer our usual rock solid reliability and market leading performance, but now at 350 bar operating pressure! As usual this one's 100% plug and play. No bending, trimming, cutting, etc. Everything drops in for OEM fitment of all harness brackets, sound deadening, engine cover, etc. And unlike the F-chassis cars, there's no need for cowl removal during install. What's this mean? It means big fueling gains in 15 minutes! Our well known cam solutions to follow along with high flow injectors. Stay tuned! Website updates are in the works and we'll be launching a pre-order sale shortly!

PSA: Our widely successful Dorch Stage 2 (DS2) has been replaced! For the better part of 2023 we've been exclusively producing and shipping our new DS25 pumps. These pumps are 250 bar capable with over 15% more flow beyond our last generation and beyond most competitors. 250 bar matters if you expect your upgraded injectors to flow as advertised! Due to some major confusion in the marketplace we have rebranded these pumps to reflect our massive performance gains. Beyond the performance, we've made fitment EVEN better with OEM low pressure routing to avoid any interference with coil pack or spark plugs changes whatsoever. As always, we're still the ONLY true plug and play option on the market with our included high pressure line. No bending, cutting, splicing, etc. Everything installs in minutes just like OEM (including all sound insulation, engine covers, etc.) So let's sum that up: • #1 Flowing B58 HPFP • #1 Fitment • #1 Control Software • #1 Customer Service • The ONLY true plug and play kit • Compatible with our +40% camshafts and all injectors
