My TT 5.4 2V build thread
After compiling tons and tons of data, I've decided to start working on adding dual T3 turbos to my 5.4L. Luckily I have lots of software and the ability to tune anything imaginable with my modis and maple sim software. Im contempating on adding an SCT Livewire from franchi for on the fly tunning, but most of my tunning will be right from maple sim and CAD. I am just not getting the results from my testing, and they are a bit off, but I am getting more and more familiar with the system and programming.
I picked up two T3's at a local junkyard today for 75 bucks each. It will prolly take a while to fully complete the build, but with summer coming I can deal with it.
I've been calculating alot of different things with my program, below are some examples. More info as I get into making the own short tube headers.
The graphs are a bit off scale due to me starting the tune at 700rpm and looking for max torque at 2300-2500. I will work on tweaking them some more. I have my max torque where I want it, but it needs to be a bit more gradual so I need to work on the sizing of the pipes and manifold pressure.
What brand did you get? T3's are pretty small, but 2 might do the trick! get us some specs and pics :thumbsup:
It will be cool with someone doing a turbo build!
I'm not looking for massive gains, just a few steps up from a sc and torque at a different rpm. Yea the t3's aren't very large, but so far they have been workin volumetric wise.
Pics coming soon. Thanks Dave
Ohh shiny! Subbed... :D
Cool! What are your power goals? Just curious...
If you end up rebuilding one of the turbos, maybe you could do a single hybrid t3/t4 turbo. I've seen lots of guys who use the t3 turbine section, with the t4 compressor section. That way you can cram in a larger compressor wheel on the 2nd turbo. Spooling wouldn't be a big deal either, since the 1st baby turbo will get the other one ready to roar when you really step on it. TT F150 is going to kick ass either way!
I honest sold the kenne bell and picked up a garret 88mm. However, after some research and math I went down to some smaller ones. Power goals: hoping to see about 550 tq. Could care less about hp. I'll run a mock up dyno later at 12 psi later and post it.
I'm still calculating the volume of pipe to the compressor wheel to maximize torque at 2500rpm.
Thanks for idea about the t4. And Franchi I'm in the market for a tuner now.
After researching I am seeing alot of guys use those T3/T4 hybrids on their 4.6's and 5.0's. So hopefully this will work for my setup.
Some more useful stuff...
The time it takes to go from no boost to full boost is a function of your total intake volume before the throttle body:
Time = (volume in cubic feet of intake/ CFM of flow out of boost) x ((60 sec/min)/(1728in^3/ft^3)) x 2
Velocity = airflow/area
CFM out of boost is roughly your hp @ a given RPM x 1.5. The 2 is a 50lbs head deduction that when going from no boost to boost, the airflow through the system doubles).
So how do you figure the volume of your intake? Here’s some pointers: I ASSuMEd that my intercooler was 300 cubic inches. Also, I made an educated guess that the total length of the intake piping would be about 9 feet. If you want to get anal, you can estimate the small diameter from your two turbos into the IC, then the distance of the larger pipe to the throttle body.
For piping volume, V = ((diameter of pipe/2)^2)* 3.14159* length of pipe in inches
2” pipe x 9’ = 340cubic inches
2.25”pipe x 9’= 430 cubic inches
2.5” pipe x 9’ = 530 cubic inches
3” pipe x 9’ = 763 cubic inches
Plugging into our time to fill, plus adding the intercooler volume of 300cubic inches,
2.00” pipe x 9’ = .244 sec
2.25” pipe x 9’= .275 sec
2.50” pipe x 9’ = .311 sec
3.00” pipe x 9’ = .393 sec
3.50” pipe x 9’ = .491 sec
What does this mean? If you choose to use 3.5” piping in your system, and are run up on by some ricer in a Fast and the Furioused stickered out STi, it’ll take ½ a second to go from no boost to full boost for your little 60mph to "show him who’s boss" mph. That ½ a second can seem like an eternity when you really need it.
The flip side of this is that going too small can cause unwanted turbulence. For most of us that will only reasonably need 750cfm for a 500bhp 5.0, then the following velocity of the air charge applies:
2.00”: 573 fpm
2.25”: 453 fpm
2.50”: 367 fpm
3.00”: 255 fpm
3.50”: 187 fpm
What do t3 turbos come out of that you got them from a junkyard. I am deffinitly looking forward to this.
This is a list of all turbos that can be used for a twin turbo setup.

Note that most of them are for engines between 2 and 3 liters. These are the best size for a 5 liter because 2 of them would equal between 4 and 6 liters.
