Bolt on turbo kit (5 Viewers)

[myersman]

yeah I totally feel for everyone right now. My sisters are all in nursing so they are busy as can be. But man it’s utterly depressing to hear how many of my customers and friends have lost their jobs

Joey I’m cool with the wait. I’m super lucky my job is essential so I don’t need a refund. Initially when this pandemic started my first thought was to cancel. I’m glad I didn’t. I think this thing will end sooner than later.

Question: I see a number of installs where the Intake Air Temperature sensor is installed in front of the turbo, rather than after the turbo. Wouldn't you want to know the turbo outlet temperature rather than the temperature of the air coming into the air box? Curious what the theory is.

Thanks,

Mike

Because the system doesn't work if you put the IAT post turbo. The MAF has to know how much air is being brought in, and MAF's don't function well measuring compressed air.

I was not clear, but I was referring to aftermarket gauges, not the fuel injection system's IAT sensor. I understand why that needs to be before the turbo. I keep seeing aftermarket sensors put into the air canister neck pre-turbo. For an aftermarket gauge, aren't we more interested in the temperature after the turbo? The temperature in the air canister is pretty close to outside air temp, most of the time. On the trail going slow in the summer, it is probably a significant delta from ambient outside temp.

Picture below from another install with the aftermarket IAT sensor in the air canister neck:

Oh I don't know enough about that particular setup to know why it is there. If you are doing it just for the turbo, yes you would want it post compressor, but if you are not doing anything about it is kind of a waste. Now if you are using it to trigger meth/water injection, etc it makes sense, but even that prevents problems spraying directly onto the element.

That is my rig.

I bought the 14-in-1 gauge for my set-up.
My primary sensors I monitor are boost, oil temp, water temp, oil pressure, & AFR.

The gauge came with numerous other sensors that I don’t have listed on my primary display. I put it there because I wanted to know the air temp going into my engine, in relation to under hood temps & ambient outside temps.

I wanted to know what my under hood temps were to determine if auxiliary cooling measures would be beneficial. (underhoodheat soak).

I have the Wits End down pipe blanket (not installed yet), and thinking of doing the Poison Spyder hood louver panel.

Well, unfortunately I did another refund on Friday and two minutes ago I just got another request for a refund. Both are due to job losses. Folks are having a tough time. I totally get it. Unfortunately my reserves are tapped out which is really unsettling because it’s a first for Wits’ End. I need to figure out a timeline for today’s request but any future refund requests please keep in mind that I won’t be able to do an immediate nor complete refund the moment it’s requested. I’m going to have to work out a schedule for payment. No other choice at the moment.

Have any of the prison shanks?

But seriously next time Im in that area of town been meaning to pick one up.

 

[Dirty Koala]

Now seems like a good time for folks to order up those odds and ends from Wits’ End that you have had your eye on for a while. I am sure there are a few things I should add to my cart today.

Went on my first shakedown hwy cruise after turbo.

Stats:

70 miles, approx.
cruise set at 75mph
total drive time 4.5 hours
max rpm 5,555
fuel econ 12.5 mpg
total fuel used 14.6 gal
Power button = OFF
max water temp = 216ºF
A/C on the entire time
max speed =80 mph
approx 12 miles of off roading with 25psi in the tires, which skewed the results somewhat. Normal street pressures are 32 front/ 35 rear.

Slight head wind most of the way with lots of steep climbs on the interstate.
She downshifted ONCE during the whole way there.

On the return trip, tried couple of things. I set the cruise at 70mph but she had to downshift couple of times. Somewhere around 75mph is her happy power band. I also adjusted the kickdown cable (aka throttle cable in the FSM) so the shifting seems more spot on to me.

I'm still experimenting with the power button on and off around town to see how I like the city driving response.

This is the FIRST time I was able to use cruise control since I moved to NM from IL, where the elevation was around 100'. Driving the 80 will become fun, once again for all those hours of seat time. Turbo made the 80 great again

This is great news and really good to hear people are happy with the results! Joey has worked really hard to make this all happen.

[Wompom]

well finally went WOT after getting my gauge installed yesterday.
HOLLEEE FOOK. Had more fun ripping this onto the highway confusing people when a big brick went flying past em then I do in my MUCH faster sleeper DD.
Max boost was 6.8psi. Water temp stayed <193. AFR stayed in a safe range. Though, my sensor was reading 15-15.1 at idle which is weird to me that its not right at 14.7. going to give it a few drive cycles as the battery was disconnected during install.

107k miles...its a baby!

 

[scottryana]

15.0 on a narrow band at idle wouldn't be unheard of, narrow band O2's are notoriously inaccurate they just give the computer a go/no-go signal.

Yeah it is! new motor when i bought it with a thrown rod and 84k. Still smelled new inside. I've defiled it since. Almost felt guilty modifying it, but i'm never getting rid of it.

15.0 on a narrow band at idle wouldn't be unheard of, narrow band O2's are notoriously inaccurate they just give the computer a go/no-go signal.

As in since the ECU is targeting based on its narrowband o2 signal? I'm not concerned with it, yet. any throttle brings it down, though some points of idle were 15.5+.
The readings on the gauge are from a wideband in the downpipe.

 

[scottryana]

Correct, the ECU doesn't know exactly what the AFR is. All that the ECU knows is if it is in range for the narrow band. Which is typically 15.0-14.2. So if you are in that range the ECU is happy.

So if your truck is idling at 15.0, the narrow band sends the ECU a good to go signal, but your wide band shows that it is really 15.0

I jut need this kit to motivate me to start putting it back together. Sitting at the 1/2 way point of a head gasket replacement.

 

[toyotaaddict83]

Have my kit installed and looking good. All that is left is to build a SS exhaust and fit/program the gauges. Very excited!

 

[NLXTACY]

I would only say to point the output of the compressor down a little more parallel to the ground.
