The Death Trap - Street Build TRD Supercharged 2011 SR5

That's about right. A

All in how you set it. Are you supercharged? Yeah, I get a tank per 3 qts.

 

Yessir, supercharged. Will definitely be looking into this more. If I have any more questions ill post up in your meth thread. Sorry to fill your build with BS @Athlaos !

 

I'm late to the party. But #racetruck builds are the best. @Athlaos I see you run the same tires as I do. Love these nittos but man they must get sketchy with the extra HP and cold winters up there.

 

I love them as well. They hold the torque pretty good, even in 1st.

I have a set of winter tires. I drove on summers for one winter a couple of years ago, because reasons. It wasn’t.... TOO bad...

 

I think I’m at about a gallon in the city. Highway it’s way less.

 

It’s all truck stuff, and even related to my build at least remotely. So no problem.

 

Finally got to the dyno. First here are the raw charts, so you can see the actual data and the AFR and the boost. Then the 3rd chart is a summary of three dyno runs - my 2018 one, my 2013 one, and a stock supercharged truck that I pulled off the forum from somewhere, trying to match the ambient conditions as much as I could.

I will say I was kind of surprised at the low horsepower gains - which basically mean not much gains at high RPM when switching to the 2.0" pulley (and with the other mods). I am willing to wager that there are significant airflow losses in the intake and the heads/valves, at least at these airflow and power levels. However, low end torque was significantly improved, so overall I'm fairly happy. The guys at the dyno were pretty surprised at the amount of torque a supercharged Tacoma put out.

Also, the engine tuners from my car club said the tune (just the UCON-EMS) was very good at controlling the AFR. They said they haven't seen many tunes that good, and they know what they're talking about - and are very seldom giving out compliments of any kind with regard to engine tuning. So, URD's UCON-EMS is, indeed, verified as good sh!t.

 

Post them here :

I bet you’ll get higher output with a stock ECU.

 

Is that the OV tune thing?

 

Few of us saw better results running the UCON on the stock ECU rather than the bully dog.

 

Oh okay, that does make a bit of sense.

 

Got mine from eBay for $125 .. huge difference. Scott will have to load a different tune tho.

 

Maybe I missed the mixture you’re running in a prior post on the meth injection, but I see people running -20 washer fluid and it seems fine. Using the same reservoir for both.

 

In one of your other threads I speculated that our little SC would run out of airflow on the top end with the 2”. I think that’s what you’re seeing as the slope of the line decreases more than the 2.825. Somewhere @Roostfactor posted the SC efficiency curves.

First of all thanks for sharing this! You are blazing new territory for us all to see.
I think you are correct as well with the inlet restriction. Stock is fine for normal levels but with your airflow demands I'm am fairly certain you are creating vacuum in your sc inlet. This of course meand the sc has to work harder to pull in air so its robbing power to try to make power.
I have contemplated chopping my inlet off right before the 180° bend and run larger inlet tubing. Just another thing on my to do list.
What size tb are you running?

 

Do it!!!!!
