Turbo Charging A Tundra!

Do you know why the IC piping is larger over the engine cover area?

 

I was wondering about that too. Maybe it’s the MAF sensor tube/housing since it’s a larger diameter and in the closest section of straight pipe to the manifold?

 

Ah. That’s gotta be it. Doesn’t look like they are putting it pre-turbo with that filter clamped on the compressor housing.

 

I believe that has the MAF bracket on it along with a built in air flow grid.

So,,,, the fuel pump and injectors still need to be added and Jesse told me about the water meth system would have to be applied to the Stage 2 system too. Not much is left.


All that needs to be done is turn the housing for the Stage 2. Then of course the piping and stuff above. Plugs are done for the Stage 1

 

OK here it is!!! WOW!! I was going nuts???? Jesse did the Dyno for the Stage 1 this morning and everything went amazingly good!! I was giving him till noon their time and I was going to send a message. I did not even wish him luck!! The Stage 1 IS NOW COMPLETE!!and Jesse is already headed back to the shop to finish up on the Stage 2!!! I am Happy everything worked out!!!




,,,,,,,,,,numbers?? What numbers?????

He said he did a couple pulls and I will let him put up the numbers and video once he gets it all ready to go. It might be a day or so but give home some time to edit, get caught up and he will get it posted.

Everything is measured at the wheel,, at 3.5PSI it was 409 HP at the wheel and 480 FT pounds of Torque. My truck I have noticed always wants to just keep pushing I guess that is one of the good things about Tundras. He then did the wastegate dump which he said sounded fricken awesome outside the truck and that was like 425 Hp at the wheels (I think he said) and I really do not remember the torque.

I do not know much more than that but Jesse will get things posted when he gets everything in order. I am sure he will answer any questions once he posts up some information.

I think the 425 HP is amazing, that would be like 103 more ponies than the stock run when this started. With the wastegate dump I think he said it hit 4 PSI or a tad more?? I am sure he will post particulars when he gets it finished.


Thank you Turbo Kits!! Jesse!!

 

Awesome! If the Hp per Psi ends up being pretty linear you may be at 520-550whp on the 8-9psi stage 2. I’m guessing they’re spraying meth during the dyno runs?

 

^^^yup the water meth system is functional on the Stage 1

 

I am hoping for the 550 range which I would be more than happy with. I am thinking it might be a bit more for some reason? We shall see, as it should not be too long of a wait this round.

 

Now we just need to know how much this could cost.

 

Yes I am curios too as I know a lot of people are. That’ll be coming too.

one thing I noticed through this, I think mounting the turbo and the intercooler are probably the most difficult to mount out of this whole deal just because of the size more than anything?? I don’t know though..??? I think I could even do it?? Not the tune but everything else. just from the pictures.

 

Man, I had a vehicle that ran hotter than I liked and was constantly watching my temps 24/7 and I HATED that. Got rid of it and bought the 2018 Tundra. This is really interesting but I am not looking to watch my temp gauges again. It has been 5 years without doing that.

Interested in seeing someone in Arizona, Texas or Nevada and their experiences

 

^^^^^In Texas is where the truck lives!
The turbo blanket, water meth system and the intercooler are all there for a reason and the reason is to keep it cool

 

Keep us posted this summer

 

Turbo blanket will keep the under hood temps down but more importantly it keeps the heat in the turbine housing to help with spool. Water meth cools IAT’s and helps reduce knock as does the intercooler. However, the added pressure in the cylinders, the bigger boom, the higher IAT’s in general, all lead to more heat being dumped into the cooling system.

 

^^^^^^^ why indeed it does,, the spark plugs have even been changed. Everything that has to do with HOT has been addressed. It would be a shame if the truck gets driven on a 100degree day and it blows up or for that matter dies a fast death and dies tires up before it hit 25,000 miles. If I thought this would happen or for that matter if they thought this would happen I am positive this would have never taken place.


If needed and I do not think it would fans can be added as well as vents in the hood. I truly think it will run cooler than that big piece of supercharger under the hood does?? Time will tell. Jesse has been running this setup for awhile making sure there is no worries and it is a complete doable addition.

but if there are any heat experts please chime in….,,,, they know how to move air without things having a melt down!! I hope

 

To add to and slightly elaborate on what @centex said, a traditional four stroke engine only makes use of 1/3 of the energy in the fuel. So if you have make 300 HP, you are burning 900 hp worth of fuel. To go from 381 hp (crank) to 500 hp at the crank, you are going from 1143 hp worth of fuel to 1500 hp worth of fuel - a LARGE and noticeable difference.

But if you are only getting 500 hp from the engine, what happens to the other 1000HP?? It turns in to heat - an appreciable amount of heat that your cooling system must deal with via engine coolant, oil, and heat transferred directly from the block to the air passing over it. The latter cooling method is fairly negligible for most motors contained between two fenders and a hood, so it's left to the oil and coolant to disperse the heat.

The cooling system on the tundra appears to be quite robust since it can stand up to the extra heat induced by the TRD Blower (which is a less efficient system than turbo's in some regards since you must make an additional amount of HP to turn the blower itself, whereas the turbo is scavenging power from the exhaust heat even though it also requires power to turn, but that's another discussion...). Anyways, that's the point that I think Centex is making. Turbo blankets and methanol injection keep heat in the impeller instead of putting it back in to the engine bay, as well as cool the air charge to make better power, but the overall heat output of the HP you are making is increased from the stock level. So additional engine cooling capacity is often needed.

 

After all,,, everyone enjoys a good train wreck!!! I am sure there are a couple around here are hoping to see something like that happen . BUT,,,,,,,,,,,,, Jesse and Sean are betting it won’t happen and I am betting a 21 Tundra CrewMax that that does not happen also!!


The supercharger is a big piece of metal providing hot compressed air and things heat up. Then there is not riding in boost WOT everywhere you go. VRROOOM!!

I am hoping to have less heat issues than what I have read about in the supercharger thread?? A big ole fan and a good metal guy might see me???

it’s all good but the Heat issue has already been discussed way back at the beginning.

Of course then I could always move to North Kadota I don’t think anything ever over heats up there!!!

 

The tundra cooling system is pretty robust, I don’t think coolant temp is a concern. I’ve never experienced coolant temps any higher than normal pulling a 7500lb. TT in summer heat and hills on 8psi with the blower. It’s the same as normal driving in mild temps, hover around 205 at most. Looking at logs when I’m not towing my IATs post blower actually drop lower at WOT. The SC kits have pretty efficient water to air intercoolers between the SC rotors and Intake valves so IATs haven’t been a big issue. I don’t know of anyone struggling with “heat issues” on the SC thread. We all just like to discuss and try to make conscious choices on the selection of the intake we are using to not use any hot engine bay air and draw all intake air from the fender well to maintain the best performance and safety.

If there is going to be a heat issue, it’s going to be related to exhaust gas temperatures towing heavy with an aftermarket turbo system as referenced in the warning of @Saltyhero13 post #233 in this thread. I’d also be trying to move the intake on the turbo system into a sealed airbox that is ducted to the fender well or front grille for cooler air to lower IATs. Are these dyno runs being done with the hood open, or closed and sucking in hot engine bay air like real world driving?

 

“We all just like to discuss and try to make conscious choices on the selection of the intake we are using to not use any hot engine bay air and draw all intake air from the fender well to maintain the best performance and safety.” From post 287

which is an issue that is discussed,,, “I am hoping I do not have to have those type of discussions.

issuses meaning “an important topic or problem for debate or discussion”

 

The hood was closed on the original dyno and I am positive the hood was shut like they all should be during the Stage 1 Dyno run or any other dyno run they do. I would like to think this is not run by a bunch of illiterates and they are pushing for real world numbers. If they didn’t I do not think a place like that would be in business very long. I would like to think that that is and should be a non issue (a topic for discussion)

 

Richard Holdener, a very respected tuner has a great video on intakes. He specifically talks about turbo setups and the intakes for them around the 10:20 minute mark. As all of his videos are, super worth the watch.

One thing about this is it can all be taken apart and put back to normal in a very short time if any issues arise. Two companies seem to think that there will not be any heat issues. Like I said I hope there isn’t any too. It should be a non topic of discussion. .

 

Don’t take any of these suggestions or criticisms toward the kit the wrong way. How you say you use your truck as mostly a daily driver which will now just see some more spirited driving from time to time I don’t foresee there being any issues especially if you keep the water meth injection system topped off. I’m simply thinking of ways in which it could be improved and bringing that in for discussion for fun and for the sake of the discussion itself. That’s what we do here on these forums!

There’s of course a distinction to be made between what works good enough, and what is optimal. Most of us with the performance oriented addiction are always thinking of what changes can we make to make things more optimal, and aren’t the “leave things alone” type of people. It’s in our nature to tinker and improve.

Im sure they will have this kit set up in a way that it will be perfectly fine for the “set it and forget it” types to install on their tundra and enjoy as a daily driver with a twist type of usage.

 

Trying to move a turbo is not a simple task. There is limited room in side that hood and where they have it I would think that that is the best place they could fit it. The stage two turns the housing which runs thru the fender out front and that is where it is going to stay. As I am not a pipe fitter nor have any ideas about placement at the moment. Maybe someone might come up with something but this crew seems to know what they are talking about and I do not know any others running a turbo at this time. If I did I would have to inspect to really see if they knew what they were talking about, to see if it would benefit my Tundra to move anything or benefit them to move their setup like the one on my truck????

sometimes things that work good enough is optimal.

 

I was more referring to leaving the turbo in place and simply piping an intake tube to the inlet from the fenderwell. It would be a sub 100 dollar job with some parts off the internet and take an hour or two. Nevertheless it’s not something you are interested in so I digress. Enjoy the kit as it comes!

 

You can see what I see. The intake runs out the fender on the stage 2 to the intercooler back to the intake. Now if you are talking about where the filter is,,, running that straight out to the front would seem like a thing to do. But as I do not have this dang thing yet I can not tell you a dang thing!!!!! I can’t help you out right now!

the best thing is to ask the guy building the the thing or suggest that to him. He would be better than I. For now I have to go with what is shown to me and I ask from there, anybody else should do to I would think.

As no one I know on this whole site is running a turbo I am opting to listen to the ones doing it for now. Until I find out other wise. I am not that smart on the subject at the moment. Running a pipe over to the fender probably would not work as the picture shows there is a pipe running over to and thru the fender already. There is limited space as you know. But thanks for the suggestion.

 

This is the way it comes. I am sure mods will be made as time goes by.

 

Thanks for this you and @centex. So what are the options a supplemental oil cooler and lower thermostat?

 

The guys running turbos are out in Southwest Asia and are pushing 1500 HP through these trucks and the other folks were running rear mounted turbos. A few have posted on these forums but aren't active here; more discussions regarding turbos taking place on other Tundra forums. Plenty of YT and Instagram action though.
