We've been seeing a lot of B58 Gen2 "simple setup" posts lately with a laundry list of parts, controllers, etc. How about just 3 parts instead? Pure800, DS25 HPFP, and S58 injectors. This combo commonly crests 700whp on E50 with the STOCK LPFP. Good for 9.4X on a Supra and 9.7X on G20/22 at full weight.

That said, the power is the easy part. This particular car has a built trans, cooling, and LPFP mods to keep things consistent and safe, which is never a bad idea👍

REPOST:

Credit to @egorsgarage 2021 BMW Z4 M40i stage 3 custom ECU and TCU calibrations on E40 flex fuel put down 690 Whp and 656 Wtq

Mods: @pureturbos pure800 (cast), @wagnertuningusa heat exchanger, intake manifold and charge pipe, @dorch_engineering hpfp and s58 injectors, @csf auxiliary coolers, PSF lpfp, @appliedtorquesolutions stage 2 clutches

Took a bit of a hiatus on social media posts, but we're back! We've been busy cooking up more innovations in the lab and on the dyno, so here's a couple teaser shots of what's to come shortly. Bigger better pumps, more applications, and some absolute game changers 👀 Stay tuned for new releases and results!

PS Keep an eye out for our typical summer sale kicking off shortly!

@myprishow has officially kicked off! Come say hello and check out what we've been hiding under the hood of the shop's F30.

It's official, the DS3 has entered the building. We have been working closely with our partners at Stanadyne to utilize the all new 12mm bore Goliath HPFP family. Our Dorch specific offering has been thoroughly ironed out at this point and offers never before seen DI numbers. Stay tuned for 4 digit results 🙊

Another great result with our Gen2 DS25 HPFP! A few easy bolt on parts and some @samehyehia sauce and you're in the 9s at full weight DI-only! There's a lot more on tap when adding our cam and LPFP, but this setup here is the sweet spot for the Gen2 cars.

Reposted @samehyehia While our goals are to push the platform to its limit. Am introducing to you a new world record on DI only fuel system.

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!
