Re: Project Lex
Just some small updates.
- Still moving forward with remote tunes. Vlad said the tune (AFR, Timing, Boost Solenoid type stuff) is looking very solid now. Just some very minor tweaks, but it's pretty solid at this point. So we're starting to look more at some of the "other/extra" features.
- So the two AEM 12pos switches I wired in for Boost and Trac control. We verified I wired them in correctly and AEM is seeing them correctly. So we've activated the boost switch. It starts out at the lowest boost setting (17psi which is roughly WG level). Then increments roughly ~2psi in each position up to I think 29psi is the current highest setting.
- We also verified the front ABS sensor is coming in clean. The rear one isn't for some reason so I need to look into that. I didn't think there was a polarity on these sensors, but I might flip the wires to see if by any chance polarity does matter. Without both working, we can't implement the traction control yet. But with the front one working what we can do is use that for a sort of boost by speed setup. In 1st gear I hook with just a very tiny amount of chirp/spin at the lowest boost setting. So we'll probably just stick with that setting through 1st gear speeds. 2nd gear it hooks decent at the 25psi setting, I have to do some more testing at 28psi, but 2nd gear speeds will probably end up somewhere around 25psi. Then no limit on 3rd gear speeds and above. And really with that in place, it makes the whole traction control piece just a little less important to me since this is sort of already helping me keep traction in check a little bit.
- I pre-ordered up the Grannas 8.8 rear diff kit. I'm going with the 1000hp axle option that retains the stock hubs. I purchased a diff from the local junkyard for $128 that I'll be getting built with a custom gear ratio and LSD. And hoping Grannas can simply make me a diff adapter that will allow me to just keep my current driveshaft. So I'll have my current 3.26 diff with Torsen LSD & Axles up for sale at some point here.
- I remade the cold side IC pipe. It was really cobbled together and was the source of a boost leak. It's been redone and is much better. Fixing these leaks has really made the car feel more responsive, but that could all just be in my head too lol.
That's about it for updates at the moment. I'm getting anxious to setup a dyno appt here soon as well to see where I'm actually at. But here's a screen shot from a 3rd gear log I took yesterday to give some sort of idea of where I'm at right now.

Re: Project Lex
Had the day off, made a couple quick videos showing where the car is at today. Walk around video and a drive around video. Drive around video was at 23psi. I usually keep it at around that or 21psi for normal driving around, and only turn it up if need be.
Hopefully have some more footage for you next week as I hit the dyno on Monday to see how she does! All I'm hoping for is a number that starts with a 6

Did you have it in the waterproof case? I can't hear anything you are saying.

Re: Project Lex
Wife lost our normal digital camera that I always use. So I used my Contour 2+ Action Cam. It's got a big piece of solid foam in front of the mic for wind noise, but muffles sound. I also had it turned down a bit. I just did a mod to it tonight so it should be louder and more clear from now on (basically ditched solid foam for a more airy kinda foam).
But I can hear it on my computer, just turn up your volume.

Re: Project Lex
Dyno'd today. Rented the Dynojet at DBPerformance. Danny was nice enough to run the dyno and the car. Vlad was remotely connected to the Infinity and did all the tuning.
We started off at Wastegate boost (~20psi) and made ~590hp. Over the course of about 2hrs we were all in on this little 61mm (~29-30psi tapering off by redline of 7500). Ignition was starting to break up once we went all in. I brought a spare set of plugs which Danny was nice enough to gap to .020 for me. That took care of the issue and the car was able to make a few clean pulls at max boost.
Ended up at 709HP / 665TQ. Extremely happy with those results as my goal has always been somewhere in the 600's. Here's a couple photos and some videos. Sorry about the sound, they have huge exhaust fans in there which make a lot of backround noise.
Bit thanks to everyone who has helped me with this. I'd try to list all your names but it's impossible to remember everyone. But you all know who you are, thanks a million for all of the help!!! I'm super stoked!

Re: Project Lex
Very awesome. So 700 on kill mode? Pretty sweet you made all that power on stock motor. Congrats. Wish I had the balls to push the limits of my car.

Re: Project Lex
Yeah 700 with my boost switch turned all the way up. But I like to cruise around town with it down at like 21psi because no need to push it hard unless I have to, like if Peter rolls up in his Vette next to me lol. Seeing how the car did today, even 21psi should be right around 600hp so plenty of fun to be had there and plenty to gap 99% of what's out there usually anyway.
Yeah the car goes straight. So today we also added in Boost by Gear. So in 1st gear now the car will be on WG boost no matter what, then every gear after that it'll just be whatever I set it to on the switch. I'd really like to try and make a pass this year as I'm pretty sure it has 10's in it now even with my shitty driving, and the Boost by Gear I think will help me getting out of the hole in 1st gear which is what I struggled with in the past on this car.

Re: Project Lex
It should run 10s pretty easy with that power and boost by gear. Plus those big meats in the back...... proving grounds in the fall?

Re: Project Lex
That's the plan. It's all gunna come down to if I can figure out how to launch it. Best 60' I've done yet was a terrible 2.1 or something I think lol. All I need is maybe a 1.9 and I should be in the 10's I think.

Re: Project Lex
Awesome numbers! I gotta ask as I'm a bit slow, why is the graph so choppy up top?
Be fun to see that thing make some passes, hopefully I can make it to proving grounds and see it in action!

Re: Project Lex
It's choppy because smoothing is set to 0. So my understanding is it's basically the raw signal. For whatever reason that is what Vlad prefers. I could add smoothing to make it smoother, which I believe is what most people do. Doesn't really make a difference to me though.
