Loaded up! Tomorrow, the E92 finally gets back on track with . Usually, we’re after lap times, but tomorrow won’t be about breaking a record… tomorrow is about drivability tuning with , calibrating the car and myself for a fairly substantial boost in power, and making sure this thing can stay cool long enough to battle. Let’s see how it goes… this will be our ONLY test day before Thunderhill at the end of the month, send good vibes this way plz.

Wow, we’ve been quiet here… sorry! This super fast and simple supercharger + stand alone install has been a tremendous lift, but we can see the light (I think!). Spending time planning, wrenching, tuning, and most of all, fulfilling orders and supporting our customers, means less time for posts, but we are BACK. For the first time since December, the splitter and bumper are back on the car. There are no boost leaks, or leaks of any kind, and the car is ready for its first proper test day on Friday. No, we aren’t going for a PB, we will be cycling the car, getting it hot (please, not too hot) and working on throttle calibration, TC and dialing in the tune. I cannot say enough about our incredible partner, . They believe in the mission — we all want to see this work. The goal here is to prove what’s possible with this older chassis and special motor, integrating Syvecs, safety and power. Maybe to break some records, stand on the podium, spray some champagne… the usual. On the last trip to the dyno, we put down 546whp/382lb-ft. Following that, the bypass valve spring was found in pieces, not functioning and leaking. Belt was worn, along with the tensioner, and slipping up top, and we had a massive vac line leak under the plenum. Without this, I’d imagine we are much closer to 600 now… should be absolutely insane at 28xx lbs. Thanks for following along, the season is just getting started. 🏁

Fuel issues be gone! When we were on the dyno with , we saw a massive fuel pressure drop by the time we made it to 70% throttle. Nice thing about Syvecs is we can see EVERYTHING, immediately. Because of this, we didn’t bother pushing any further, which netted a safe 515whp, but who cares about numbers. We’ve been looking for a good fuel pump solution for the E9x M, and somehow, it just doesn’t quite exist, at least for the stock ECU and easy to drop-in like M3’s turbocharged non-M siblings with N54/55. But since we’re on stand alone, we can wire up two extra pumps directly to the computer, and it turns out Radium has a gorgeous surge tank kit that’ll sit in the other side of the saddle, utilizing the factory pump assembly to feed the tank and keep the OEM system easy and unchanged. We’ve opted for twin Walbro 525’s which should give us plenty of headroom for big injectors and E85 later, but best of all, should continue to allow us to run the car low and light! Still waiting for the feed side of the kit, but once that’s here we will get it installed and head back to the dyno for tuning. CANNOT WAIT TO DRIVE THIS MISSILE. Last slide is a preview of a future post with some cross-country R&D between myself and the legendary .

Put your AirPods in and turn ‘em to a million, the E92 sounds INSANE. Finally, a limiter that does this thing justice, motorsport TC, 515whp (at 70% throttle and 7600rpm!) and I don’t even know what else to say. It just keeps evolving. The supercharger adds quite a bit of weight in the wrong place, lap times will tell us if it’s worth it. This current stage wouldn’t have been possible without . We’ve been working together on our F8x S55 and G8x S58 packages, but this is our passion project and it’s only the beginning. We need more fuel, for starters, so that’s first on the list. Once we sort the pump, we will see what it’s like with all the beans. Cooling needs work, too… amazing first test on the dyno and I cannot wait to experience this thing on track. Till then, enjoy the noise. Thank you to for the amazing facility and hospitality!

WE HAVE A RUNNING CAR! Been wrenching on the E92 slowly, methodically, over the last couple weeks. Before the TA season starts in full force, it was time to find out what the car would be like with a 200hp boost. No, this was never the plan, no, I don’t think this car needs a blower, in fact, it’ll be tough to beat NA. HOWEVER, Time Attack is an arms race, and it’d be nice to even that battlefield a bit. The coolest part is what you can’t see, though. A full Syvecs S7+ is now in place of the factory computer. We’ve got a custom harness added in with knock sensors and a bunch of other sensors. The car gets full motorsport TC, and today it runs thanks to the amazing team at . Few things to sort out and then it’s off to the dyno this week. Before you go nuts, just know, this is a test. If things are looking good, this boat anchor of a kit will go through some major revisions. Questions? Thoughts? Concerns? We have those too.

It’s funny… doesn’t matter how long you’ve been going to the track, how many times you’ve been to Buttonwillow — sometimes you just keep learning the same lesson over and over again. I won’t lie, it’s been surprising to keep finding time in the E92. I never thought it would be doing 45’s… and when you keep chipping away so consistently, you get a little greedy, maybe a bit hopelessly optimistic. Conditions weren’t great at last Friday’s event — nobody was breaking records. I just couldn’t find the grip. Did a handful of 48s, which is crazy to feel disappointed and off-pace there now… so the 1:44 will have to wait! I ended up having the best day ever, otherwise, just hanging with so many friends, driving a completely underrated car, the 370Z. Thanks for that ! Seriously, that chassis and drivetrain is special. I’d love to build one out a bit. Also drove an insane AMG GT-R by and a new client build, an OG M2 from .alcohol.md. And now? It’s time to see how good or bad boost will be. We have enough time to test before the competition season starts, so this car is getting Syvecs and a blower THIS week, and then is coming in to work some magic.

Looks like PB weather to me.

STICKERS. The coolest tire rice from , except it’s the real motorsport stuff, and we’re headed back to Buttonwillow tomorrow to see if we can get some more heat in the tires and go faster than the 1:45 lap from a few weeks ago. After tomorrow with , it’s time to make some changes and keep this thing evolving.

Excited to welcome to the program this year. How often do we see new lubricants coming out, designed specifically for the high-strung motors we love? Proper race stuff, made by people way smarter than me — no garbage in here for the road. Ready for some 8600rpm pounding and it’ll be in the store soon!
