The Truth About Harnessing Power: A Journey with the LS7 Engine

As we embarked on this journey to harness the power of the LS7 engine, we encountered various challenges and obstacles that tested our patience and ingenuity. The first step was to create a suitable environment for experimentation, which required us to set up multiple screen options, GPS, and other necessary tools. We were fortunate to have a "truth" harness in place, which provided us with the necessary feedback to fine-tune our modifications.

One of the initial modifications we made was to relocate the computer that had previously been mounted on a different part of the engine. We removed a vacuum block and repositioned the computer to its new location, inside the engine compartment. This move required some careful planning and execution, as we had to machine a custom plate to accommodate the new configuration. The process proved more challenging than expected, with one attempt resulting in a failed outcome that required three additional attempts to get it right.

Another issue we encountered was the fuel pressure regulator, which was causing low fuel pressure readings. Upon investigation, we discovered that the vacuum line had become detached and was spraying fuel into the intake manifold. This problem led us to reevaluate our approach and make necessary adjustments to rectify the situation. With each step of the process, we were able to refine our understanding of the engine's behavior and optimize its performance.

One of the most significant modifications we made involved upgrading the throttle body from an LS1 unit to an LS7 model. While this may seem like a straightforward task, it proved to be more complex than anticipated. The new throttle body required us to machine a custom plate, which took three attempts to complete successfully. Despite the challenges, our persistence paid off, and we were able to achieve impressive results.

As we progressed through the tuning process, we encountered several other issues that required attention. We upped the red line from 6,500 RPM to 7,200, but ultimately decided to run it at a lower speed of 6,800 to ensure stability and control. Additionally, we removed another coolant tank, which allowed us to refine our cooling system and optimize engine performance.

With the car now assembled and ready for testing, we opted to drive it over to the dyno with the hood off, showcasing its sleek design and aggressive stance. The plan was to fine-tune the engine's settings and monitor its performance under various conditions. After making some initial adjustments, we were able to achieve an impressive 570 wheel horsepower at 11 pounds of boost.

Encouraged by these results, we set our sights on increasing power output even further. We decided to push the wastegate spring to 13 pounds of boost, which resulted in a significant increase in horsepower. Our efforts paid off, as we achieved 630 wheel horsepower, well above our initial expectations.

The next step was to plan our transport from one location to another, ensuring that our vehicle would arrive safely and on time. We considered various options, but ultimately decided to rely on our truck, which had become a crucial component of our operation. This move required some creative problem-solving, as we had to navigate around logistical challenges to ensure the safe transportation of our car.

As we approached the final stages of our journey, we reflected on the numerous challenges we had overcome and the lessons we had learned along the way. We realized that harnessing power from an LS7 engine required patience, persistence, and a willingness to adapt to changing circumstances. Our experience served as a testament to the complexity and beauty of engine modification, demonstrating that even the most seemingly insurmountable problems can be solved with dedication and expertise.

With our car now ready for transport, we began making plans for its participation in the upcoming Dream Racing event at Las Vegas Motor Speedway on October 25th. We were excited to share this experience with others and showcase our creation's capabilities. Our event would feature open lapping sessions from 7 to 10 am, followed by additional time for settling out any discrepancies.

To participate in the event, interested drivers could sign up through a link provided in the description. As part of the contest, we planned to offer signed posters of our team members, along with other prizes and recognition for participants who achieved impressive lap times. The winner would be crowned based on their performance, with our predictions suggesting Matt Farah taking first place, followed closely by David Patterson, Tommy F., and Rob Dom in second, third, and fourth places, respectively.

As we look to the future, we remain committed to sharing our passion for engine modification and exploring new frontiers in power generation. Our journey has taught us valuable lessons about perseverance, creativity, and collaboration, and we hope that others will find inspiration in our story.

"WEBVTTKind: captionsLanguage: enall right mom and the truth harness is in fingers fall just need noise to come out of there Jakub raining outside all right thank god we've got multiple screen options like all sorts of fun stuff and we got the GPS that lager there yes module and we're working we're good I like this and this is my new traction control switch that turns traction control on all right so what are we looking at right now we're outside on our own power good move what have we changed well we've taken the computer that was over here that is now gone they remove this vacuum block we have changed the the computer location is now inside there we had to get rid of the ls1 throttle body go to an ls7 throttle body which sounds really easy but it was not we had to machine that custom plate and that took three attempts to make that plate there so that's one thing the fuel pressure regulator was the problem and the reason we dine out very low if you pulled the vacuum line out of it it was just spraying like a hose and that goes back into the intake so literally we were pissing fuel into the intake which is probably why the AFR and I didn't think the fr I was reading but it makes sense now why the AFR was reading a tow and the dyno and why it made 550 horsepower we're upping the red line a little bit he was revving it to 7200 but we're gonna run it at about 6800 and it was previously 6,500 I got rid of this other coolant tank here so we're gonna drive it over to the dyno see what it does and just for dramatic effect let's drive it with the hood off because that looks pretty badass all right you can't see because I'm outside in the Sun right now but my pets right there on the dyno at 4:00 spread engineering racing in Deer Park and we're going to get girl run all right so this is pointing up the tune a little bit but that's 570 wheel horsepower at still on the wastegate spring ten pounds of boost so we're shooting for thirteen pounds of boost you electronically cut of that they cut the boost but we were starting to make more horsepower seat it was going up that way and then it was like who's cutting him safe to say we have a working car which is good and now we have to figure out the transport situation and like it was one of those things I didn't want to put a lot of thought into I've got a couple of lines in the water but it's usually when we've blown out the window of commercial transport we have to go my truck which is now in the way to Kentucky is out so we got to figure out a way to get my car probably Rob's car if he can get it done across the country in like four days five days so that's my new challenge but just be happy at this car as as predicted going to Vegas it just proves anything can be solved if you throw enough money at it got much more expensive and I was hoping it would be Wow all right back at the shop and the car made about 630 wheel horsepower at 11 pounds of boost we're not gonna run anymore than that I'm probably just gonna run enough the wastegate spring which is about 6:20 6:15 6:20 whatever plenty of horsepower more than enough to win in Vegas what's going on in Vegas the 25th of October we're going to be a dream racing 7:00 a.m. to 10:00 a.m. at Las Vegas Motor Speedway you guys are more than welcome to come out and spectate who are you gonna see myself Matt Farah maybe Rob Dom if this cars ready David Patterson and Tommy F yeah and a professional driver who is I don't think it's a secret Justin Bell and Justin bells gonna be laughing all these cars we're gonna be lapping these cars gonna be a lot going on if you guys want to sign up to also participate we're gonna be doing contests sign up in the link in the description if you drive a dream racing at any point in time and you sign up through our link we're going to hook you up with some signed posters of all of us at the track it'll be good you'll like it and then we'll pick people by lap time and we'll give them prizes signs stuff and maybe even the dinner invite if you participate on the 25th so how it's looking to work is we're gonna be doing our driving 7 to 10 open lapping for you guys or anyone else between 10 and 3 after 3 o'clock we need additional time to settle it out we will but we'll catch you guys in Vegas thank you for watching check the link in the description my predictions as far as who's coming in where I'm gonna come in first because me Matt Farah coming in second Dave Patterson will know Tommy he'll come in third David Patterson fourth and Rob Dom if he finishes and probably won't finish play he'll be dead last it's my prediction write it down subscribe you'll see more that's next\n"
