Turbo Charging A Tundra!

Got me eyeballing some meth over here

https://www.proimporttuners.com/parts/toyota/tundra-aem-water-methanol-injection-kit.html

 

Properly size they do a great job. Will be curious to see what they look like after some sustained runs and heat soak but I don't think they'll be that bad. Keep up the good work.

 

LOL or here! https://www.turbokits.com/aem-v3-water-methanol-injection-kit.html

But in all seriousness, we love water meth, been running it on kits since 2005, back when we had to get the aquamist kits from the UK. Its cheap insurance and emulates running 100oct but with pump gas and only when in boost, plus the charge cooling. It's really is a no brainer on ANY FI motor. Especially the newer direct injection motors with carbon buildup, the water meth can help keep that down (if started from new or cleaned engine). Anyway, there are just a lot of benefits and we love it...

 

Cool, I'd rather purchase from someone active on the forums! What's the difference between the two linked products? I can't see any from pics. Just that one says Tundra, and the other Honda. Guessing the wiring/mounting brackets?

 

All the cool kids are doing it.

 

Nothing that I can tell, their site is misleading a bit by saying it will fit the Tundra. It's universal, it would work on a lawn mower if you installed it properly, LOL. So keep that in mind, these are universal, so you have to mounts them, wire them, run the pump and lines, etc.

 

How would you implement it? Everyone always says the meth eats the coating on the SC rotors. You would have to inject it post rotors by drilling and tapping a fitting into each intake runner. Sounds pricey.

 

Oh, no idea lol. It hasn't gotten past the, "Hey that looks cool I could probably use that" phase of thinking. That looks like a lot of work, probably won't happen

 

That's a nice kit. May be easier to design a riser with ports.

 

I've used the snow kits in the past but they are all fairly simple. The kit I used was boost referenced and progressive so as the boost started to rise, the system would inject more. Below a certain threshold it wouldn't spray. They are pretty universal and basic.

 

Tuning this time seems to be moving right along, the hold up has been the snow storms. I imagine that if they could get some clear weather that lasts for a few days the tuning could be complete! Again, once the tuning is complete back to the Dyno for the final run

 

Got the go ahead from the tune to test higher boost, had to get prepared for an almost 2ft of snow, storm, coming in tonight through Wednesday, but was able to get the boost up to 5.5-6 PSI and get some logs to the tuner... Wanted to keep posting the IATs from the logs for everyone to see. It was 36* the ride in this AM, 41* IATs cruising, 46* at the top of a 6 PSI peak boosted run...

 

is it "normal" for a turbo engine to only add 10 degrees of IAT?

or is this exceptional?

 

A properly sized intercooler will do wonders bringing the intake temps down as close to ambient as possible.

 

Meth works wonders too:

 

Yeah I didn't want to say that those are the IATs before Meth comes into play, since the meth nozzle is after the MAF and not part of the IAT readings, but yes, the meth is then taking this small differential and bringing it back down to ambient or even a few degrees lower! We are a big fan of Water Meth, I personally have it on both my personal turbo tundra and my sport car.

 

Good to know when we are looking at these logs. Thanks.

 

Yes correct, we state the Meth was after the IAT sensor in this post: Turbo Charging My Tundra! | Page 13 | Toyota Tundra Forum (tundras.com)

Which you can physically see in the pics on this post: Turbo Charging My Tundra! | Page 13 | Toyota Tundra Forum (tundras.com)

 

Yes. I forget that in the middle of this frothing orgy of boost.

 

Don’t get me wrong, air to air intercoolers work great, but this data is a poor representation of the reality of the IATs. Cruising along on a 30 degree day when not making any boost like on this log, the cool ambient air pre-cools the whole mass of the intercooler to 30ish degrees. Then we are shown a 55% throttle pull at low boost for a very brief period from 45-72mph looking at this log. The minimal heat discharged over that brief low boost pull is not going to present a scenario that will ever heat up and saturate the intercooler (especially in it’s pre-cooled state), and show true IATs under a sustained boost scenario. The point is we aren’t concerned with IATs on a 30 degree day for a 5 second pull from 45-70mph. That’a not why there is interest in the IATs.

I understand @TurboKits.com is showing us this just to show the IAT data he has available so far at the current tune limitations. He’s showing us what he has, but this little snippet of data doesn’t really tell us what we want to know. What we really want to see is the IATs on a 100 degree Texas day on a sustained boost pull from 0-100mph like on a 1/4 mile strip; or IATs pulling a 9,000lb travel trailer up a steep grade for 2+ miles.

If you a want to know the real IATs of a given scenario then enter them into this calculator. Input temp will be underhood temp in this case. A Generous efficiency input for the turbo is 75%, and a generous efficiency input for an air to air intercooler is 70%. Plug some numbers in and you will see the reality of what to expect.

Just trying to dump info as we have it... Thanks for your input. Working with TurboKits.com will not be for everyone and we understand that...

 

We'll I for one appreciate how you've graciously answered questions and shared information about the development of this kit. Clearly this isn't the first truck platform you've fabricated a turbo kit for as your personal and business reputation precedes you.

As far as addressing skeptical forum questions, we mean well even if it is hard to sense tone and intent from some of our comments. Modifying trucks comes with trade offs; these questions are aimed at helping understand what those trade offs will be with a turbo kit.

At this stage it will be difficult to know all the answers based on a one off prototype run, especially for a new platform. Some of these answers will only shake out as more owners adopt the kit and run their trucks through the gauntlet of "truck duty" activities.

 

That was what I was getting at as well, glad we are on the same page! We only have the info we have, the rest is speculation. If that means some owners don't want to take the jump until that info is out, great, we'll keep building and testing and posting our and customers feedback until we have all of the info possible out there for everyone. Thanks again!

 

Don’t misunderstand my questions as anything but excited and curious to see the results of the kit and am happy to see more support for the platform. I think it looks like a nice kit! Just prodding for answers that I understand we don’t have yet, but are nonetheless important considerations for potential purchasers depending on how they use their truck. My intent is to make suggestions on providing some important info possible buyers may like to see and then when possible see it recorded and presented in a way that doesn’t leave anything to question.

The IATs we have so far look great, I’m looking forward to seeing how it looks under sustained boost runs. If it’s within 50 degrees of ambient on a long pull in high heat at full boost (without the meth) I think that is a success.

 

The only question I have is regarding pricing. I’m gonna assume 8-10k uninstalled.

 

The IATs will always be "without meth" since our meth nozzle is after the IAT sensor, so even tho the meth is helping cool the intake charge and increasing the active octane rating of the fuel, it is not ever going to be part of the IAT readings in the HPT logs. That info would be purely what he turbo and intercooler can do.

 

Stage 2 less

Stage 1 much less

We'll release the #s once we have the stage 2 layout 100% and can get it all quoted from our mandrel bender, but our plan when we started was to give the same if not more power for less $$ than what is currently out there.

 

You had my interest but now you have my attention.

 

Yup I understand that. The difference for me is I personally don’t want to depend on a meth system on my pickup truck so any benefits it may have wouldn’t be considered anyway in my case.

 

questions:

at what temp does the meth activate?

is it a single dose or is the amount metered to IAT or boost?

How is the true meth-supplemented IAT known if the sensor is before the meth?
