Turbo Charging A Tundra!

Thanks! I was considering the insulation kit below to wrap the junction box in addition to the insulating tape for a better appearance and as an additional protection.


The basalt laminated shield can be an option too. The same one you used in the cross over pipe. BTW I received it last week, thanks for the links!



Another view angle for the junction box.

 

I can't speak to the battery mat, but if it 1/2 as good as their mat, the. It should be fine. The tape is also holding up but I can see where a heavier product would be better (on my install, anyways). Staying tuned to see how your product selections progress. I envy your time and attention to detail. It's going to look fantastic when it's done.

UPDATE 09/10/24:

We have pretty much maxed out the Stage 1 coupler / MAF flow with the 650cc Inj. 5-6 PSI is where we start running away from fueling control, but boy does it scream!!! This is just basic scaling per the normal stage 1 coupler (3.4" ID) and high flow MAF (no crazy tuning tricks). This morning, we installed the Stage 2 and are dialing in the tune now. If all goes well, we'll get on the DYNO this Friday, do some runs with the stage 1 and then flip the compressor and connect the Stage 2 and see what we get there as well. Which us luck!

 

Can't wait!!! Good luck!

 

Amazing day at the DYNO!! We averaged 517 HP and 577 TQ at the wheels at only ~ 7 PSI. This was over the course of 3 back to back runs once the tune and boost was dialed. We adjusted the tune and boost and hit 526 WHP and 578 WTQ and then tested a few more tunes and went back to that one. We then ran 3 back to back runs to make sure it was consistent for the average above. The best one being 520 Wheel HP / 584 Wheel Torque! Needless to say the Stage 2 set up has bested our goals of 500/550 and is insane! We have a few hours of videos to go through and we’ll put an “official” post with the videos better DYNO charts, etc, but first we have a 6+ hr, 350+ mile tow tomorrow to drop off a project car for engine transplant and 2 new ball bearing turbos. So from the DYNO (20+ Runs), right to trailer hook up, car loaded and ready to go for the morning. Tundra + Turbo = Amazing!!!

 

Awesome! I feel the need to speed up my install!!

I spent few hours today looking the best spot to install the water/ meth controller.
But not 100% sure if I will keep it where I finally decided to install it.

 

I snaked wires and hose through the center console and into the passenger side of the storage bin under the arm rest. Easy to reach if you need to adjust it, hidden and out of the way the other 99.999999999% of the time. Everything you need to know you have in your gauge pod. Clean install as is, but I don't like anything anywhere near my brake controller.

 

@TurboKits Duuuuude! I was thinking we'd be at 8-9psi for these numbers!! Cant wait to hear about how it goes tomorrow while towing and to hear the rest of the details.

 

Good catch! Didn't think about it. I haven't use it so far but it is a posibility. For now I just moved the controller a bit to the right to improve the available space. This is how it looks now...

 

Interesting spot for it. I don’t hate it

 

Figured there was a few minutes of down time on my part so I wanted to continue documenting the towing experiences I've had this first season. Last weekend I ended up towing back into the White Mountains and I am happy to report that all of the details above remain consistent and are becoming my new baseline while towing, at full capacity.

I am averaging 7.5mpg on all of these trips which have accumulated approximately 750 miles at this point. My final trip over Columbus Day weekend will put me at the 1k mile mark since going Stage 1.5 with the appropriate heat treatments. On this last trip, staying around 70mph, I went through about 1/3 of a gallon of water methanol. On the return trip (faster than I typically drive due to traffic patterns), I burned through 2/3 of a gallon. Both of these are over nearly 3 hours and almost 150 miles each. With the temps and humidity being more pleasant, I've got the system dialed in right at 4.0psi peak boost. The truck is extremely content in 5th gear until about 60/65mph where it prefers 4th (2300rpm vs 2900/3000rpm). Most importantly for me, I can hold AND INCREASE speed anytime I want utilizing only 4th and 5th gears, and boost really only comes on when on decent sized hill climbs. Otherwise, I can hold at 0.0psi (in 5th) or < -4.5 (in 4th) and not be hunting gears or losing speed which really make towing so much more comfortable and also explains the reduced water methanol consumption. While I recognize @TurboKits is now working to find the limits of their systems, I am beyond excited and pleased with how well this truck is performing with such a modest configuration and tune.

As a reminder, I went from Stage 1 @ 3.5psi with water methanol only and "conservative tunes" where I essentially ended up limping up a mountain and burning through 1.15 gallons of water methanol in less than an hour to now being able to go hundreds of miles on that same amount of water methanol with cooler IATs due to the intercooler and a more performance based tune. DRAGY times confirm the improvements as well for when it is being used for fun vs work. Those times will continue to improve once I address the stock fueling limitations currently in place, as this entire towing season is on stock pump and injectors. Some good lessons learned, lots of data collected, and some proven product testing across multiple vendors has been a fun journey and I'm really looking forward to seeing what the 2025 towing season looks like with full Stage 2 running at 7-9psi, especially after the numbers @TurboKits just posted on Friday. I have one more gauntlet to put the current configuration through this season and I'll report back on that, in detail. Conveniently, it will also put me right near the newest 4k mile OCI that Blackstone recommended, so I'll be able to get that sample in as well. That trip will be the end of the towing updates for me this year, but will bring this part of my journey full-circle since I'll be taking the same vehicle on the same route as the one described earlier in this post. True apples/apples comparison to see how far the truck has come. If anyone cares for more of those details, they can be found in this post: https://www.tundras.com/threads/turbo-charging-a-tundra.115951/page-39#post-3623296

I'm really looking forward to what @Jego does with his install and I am very excited to see what @TurboKits continues to do between now and my Stage 2.0 installation. I'm just enjoying the truck as a family hauler for the next month, enjoying cruise nights (it does get a surprising amount of attention), and then it will be going in for some minor surgery sometime after that. Jesse and I have had a number of discussions about future heat management solutions and final configurations for what the truck will be in the end and I'll be sure to post up about that next part of my journey. Performance will only be captured via DRAGY times until next May, though, but I look forward to being in the 500whp club

Always around to answer questions and just because I'm not posting doesn't mean I'm not active. I continue to learn a lot from everyone and I want to say thanks to everyone who has been following along and for those of you who have chimed in with your own FI data points to assist in my journey.

Cheers

 

Hey All, we haven't forgotten about you... Last few days were bonkers and we are still catching up on order from last week. We'll get the info posted, hopefully later this evening. Thanks!

 

Tow Results #3: 2014 Tundra, Stage 2 Kit, Water Meth, 650cc inj & Tune, ~7 PSI, 141K Miles on the Odometer

The quick details of the tow on Sat 09/14:
U-Haul Car Hauler 2200lbs & 2017 Infiniti Q50 4000lbs: ~6200lbs
Average MPG: 14.6
Town to NH: 193.7 Miles / 14.75 gal = 13.13 MPG
Trip back to CT: 168.7 / 10.48 = 16.10 MPG *the closest gas station, easily accessible with a trailer was about 20 miles away from the shop...
Meth Usage: A little over 1/2 tank *this included the 20+ DYNO runs from Friday and the road testing after the DYNO. So the meth usage from the DYNO day to the tow was a little more than 1/2 a tank.
Duration: ~9 Hours
Road Conditions: Dry, about 75+* ambient
Traffic: Light; Back roads, traffic, plenty of highway and lots of hills.



The trip up to drop the car off from CT to NH, is pretty much all uphill, many long sweeping, higher speed pulls and some real steep with sharp bends, so we had no choice but to hold the boost. 1st leg of the trip was 197.3 miles. This included grabbing the trailer and loading the car. The second leg, the return trip, was #1, mostly downhill and #2, just the trailer.

The truck ran perfect, never had to guess at anything, logs were exactly where we wanted them, with LTFTs in 2.3% B1 / 1.6% B2, Knock learn maxed and was holding flat line at 18.1 and we had flat line on the KR feedback as well (see histo). This was after ~400 miles of consistently heavy driving.

All we have to say is 20+ Runs on the DYNO, breaking over our 500WHP goal, right to a 400 mile, 6200+lbs tow the next day, while averaging over 14 MPG, and only using a little over a 1/2 a tank of meth... What else could you ask of a truck? Tundra + Boost = Amazing!

Welp, it's almost midnight and I am falling asleep editing DYNO videos. Am out of state working on another truck tomorrow and then I promise I'll get the DYNO videos and charts up and the pricing for the stage 2, 100% locked. Thanks again everyone for following and you help and support!

This is a hell of a flat smooth log chart!

 

DYNO Results - Stage 1 with Injectors: 2014 Tundra, Stage 1 Kit, Water Meth, 650cc inj & Tune, ~5 PSI, 141K Miles on the Odometer, Stock Motor, Stock Trans

We took our 2014 up to the DYNO at ECS performance in order to test some higher boost levels with the Stage 1 kit, now that we have the fueling from the Deatschwerks 650cc injectors. We were able to get to mid 5 PSI range before running out of room in the MAF scaling. This is with no MAF tricks, etc, just allowing it to keep the standard scaling.

DYNO Results: 470 WHP / 515 WTQ at 5.5 PSI

DYNO Results - Stage 2, Intercooled with Injectors: 2014 Tundra, Stage 2 Kit, Water Meth, 650cc inj & Tune, ~7 PSI, 141K Miles on the Odometer, Stock Motor, Stock Trans

We took our 2014 up to the DYNO at ECS performance in order to test the Stage 2 Intercooled set up with Deatschwerks 650cc Injectors. Our goal from the beginning was a simple bolt on kit that could crest the 500WHP mark. Needless to say, we did that and some and consistently!! This was done on Friday, the ambient temp was 85* and the DYNO cell was showing mid 90*. We started with the Stage 1 testing and without even unstrapping the truck, swapped to the stage 2 and continued testing. Ended up with about 20 runs over a course of 4 hours.

DYNO Results: 520 WHP / 584 WTQ at 7 PSI

2014 Stage 2 Turbo -vs- 2021 with TRD Intake & Exh to show gains

 

I appreciate that you guys know how to properly show dyno numbers


kudos

 

Thanks, that's actually our old DYNO, we have close to 2000 R&D runs on all of the products we have developed over the years... Happy the experience we have with our "proving grounds" phase shows!!

 

I’ll bet that thing trucks when it comes up on boost. That’s impressive. Now if I could just stop with the house repairs so I can stack up for one of these.

 

You can sleep in your truck, but you can't drive your house!!

 

Great numbers! Looking at the dyno curves it looks like it would be a fun ride and a very different experience of acceleration compared to the SC. Comparing the dyno charts to the collection of SC charts posted on another thread, the torque curves are definitely different. Turbo looks like a big gob of torque especially from 3400rpm to 4700rpm. When doing rolling WOT runs it should be sitting in that rev range a lot! The SC torque curves are more like a flat table top of torque from sub 2500rpm to 5500rpm but less peaky in the mid range. The graphs look like how my personal experience of owning a turbo vs SC vehicle actually feels….I do sometimes miss that Legacy GT.

 

Yeah, the way I did the DYNO was to start the software reading at 2500, get to 2K and then roll into it, you can see the full throttle mark around 2800, plus its over 500 Wheel TQ from 3300-5400!!

But yes, it's exactly where the powerband is when driving the truck on the street, connected to the gas pedal with turbo whistle and boost on demand! It's amazingly fun, with all the right noises!

 

Tell the wife that haha.

 

Awesome work by all in this thread. I’d love to see a bore scope of the cylinders on one of the trucks running the turbo with H2O/Meth injection. Bet those pistons are shiny!

 

Another benefit of the Meth. It especially helpful on Direct Injection motors! Thanks

 

All the kudos from me goes to Jesse @TurboKits for building the kit and having my back more than I could have imagined throughout this towing season. The fact the kit has done wag more than it was initially intended to do, in the wild, is a testament to his knowledge and R&D process. Nice seeing the dyno results to document what logs and story telling simply can't.

Regarding the scope work, there could be an opportunity for that if @TurboKits signs up for it during the 2.0 conversion on my truck in the coming months, but that would be his time and resources, so talk nicely to him and maybe it could happen. It wouldn't be the worst thing to swap plugs and close the gap down a bit ahead of more boost, so... definitely, maybe, there's a chance.

 

Segregating wires from/to the water/meth controller!

 

Overwhelming at first but I opted to divide in multiple stages... Internal to the cab from external, then broke down each circuit like you have. The pump was strange, too, since this expect it to require a heavier gage wire than what comes off the harness.

Hint: run 2 each power and ground through the firewall, one for the AEM and one for the SCG. Easier to pull together.

 

Yes it can be overwhelming, but I like to do all that . I have the same opinion about the pump wires. I used gage 14 wires from the pump to the interior. In the picture above you can see it in the passanger side coming from the bottom right section. There are 2 for the pump and 2 for the level sensor.
Good hint! In my case I already had a power cable gage 8 from the battery to a terminal below the driver seat. I will use that same terminal. I made a new hole for the vaccum hose. In this photo you can see the power cable that I mentioned here and the vaccum hose.
