Okay, new injectors are in and working great so far. Took the car around the block a few times and got into the gas a bit. This thing is gonna be spicy. Looks like it starts to make positive pressure around 2700rpm in 3rd gear. Had some safeties setup wrong and it was stopping me from going passed ~3000rpm so I wasn't able to get into much more than ~1psi.

Hopefully be able to take it out soon and get some data.

 

Made some block offs for various things that I no longer use/need in the interior

 

What material is that?
I've deleted the AC/Heater controls in mine and would like to fill the space with something but don't know what to pick.
Carbon Fiber looks cool, but I've never worked with it and that material you used looks great.

 

So, I took the car out this weekend. Overall, it went well. Just a couple of small issues that I have sorted out already.

First one was, tried to get into some boost and I believe it hit one of the safeties I setup in the tune (fuel pressure). I believe once the second fuel pump turned on, it blew a hole in one of the fuel lines inside of the fuel cell. I was able to limp it into a parking lot. Went to the near by autozone and got some supply to fix it. After that, all was good. The next day I went and got some submersible fuel line to fix it the right way. The quick fix prior was just some regular fuel hose from autozone.

Apparently, at the same time, I ended up running out of fuel. I thought I had topped off the tank prior to the drive. It really only had some idle/rev time on it. Then I remembered that I pulled the fuel rails a few times and lost a good amount of fuel each time. At this point my fuel gauge was not working. (I think i have it sorted now)

After I got some enough fuel to get it to the gas station, I topped it off. The extra weight added to the rear ended up making the rear end squat more and the tires were rubbing on the fenders under acceleration. I shaved the inner lip on both rear fenders and now have a good amount of clearance.

The one pull that I did try really felt kind of gut-less. I do have quite a bit of timing pulled out of the mid-range/peak torque area and don't think i even got passed 5000rpm before the safety kicked on (didn't get a log). So I added a few degrees back to that area. I think its still pretty conservative but should be better.

 

These pieces are 3D printed. Modeled and printed them myself. The material is PETG CF. It prints very easy and depending on the orientation, the finish comes out smooth. You do need a hardened steel nozzle to print it.

 

Drove the car again over the weekend and finally got into some boost! I thought the wastegate springs that I had in there were 8psi but turns out they were 4psi. I did the pull in 3rd gear and it made around 3.5psi. So the gates/priority are working. (I was worried I would have to step up to bigger gates, so this is good to know that they work as is) In the log everything looked good. It was adding about 10% fuel through the whole pull. Not terrible considering I guessed at the whole fuel table.

Once I got home, I did find some oil outside of the motor. From the valley cover area and the rear driver side. I ordered up a new valley cover gasket and replaced it. For the rear driver side, I thought it was the valve cover gasket but it turns out I completely forgot to plug one of the extra bolt holes on the back side of the head (heads have both LS3 and LS7 bolt patterns). Got that all sealed up and hopefully no more issues.

I also ended up trading my cowl hood for a vented hood from another member on the forum. Had to do a little cutting to get it to work with the intake.

After the last drive I pulled off the exhaust and added some turn downs in the middle of the car. Needless to say, I put the exhaust back on, lol. Not about that dumped life anymore, I guess. Would probably be better if it didn't dump under the car but I'm okay with it for now.

 

The droning you get from dumps under the car is the worst, especially at cruise.
I'd much rather have a fender exit than that lol.

 

I get annoyed at having my wastegates dump right under the car, and that only matters under boost. I can't imagine cruising with the whole exhaust dumped like that.

 

Yeah there was a small area under acceleration that it just rattled my brain. Had to accelerate real slow and shift early to avoid it. Definitely not worth it. Ironically though, when it was NA I had it dumped under the car the same way and it was no where near that bad.

My ultimate goal is to route the exhaust to exit similar to how the Vipers have their exhaust exit, right in front of the rear tire on the fender. But i am still debating on that.

 

Made a pull the other night on wastegate (~9psi).

Recorded the pull on my Meta glasses. Audio is not that great though


Couple small issues I need to fix and it'll be ready for the dyno.
