Yes, very nice. Heck, I will throw in a request for a classic quarter mile run.

Scotty, firstly, congratulations on the results.
A few Q's;
1) what engine management system are you running?
2) since I assume it was run on a chassis dyno, what are the figures at the wheels and what conversion factor did you use to work out the engine figures?
3) that's a heap of boost to get those numbers. Have you got a dyno print out to post up?
As for the trans coolers, I'm running a single B&M trans cooler (the largest one) at the moment as I'm experimenting with airflow and cooling. It is winter here in OZ so not very taxing on vehicle cooling systems. With one cooler, it is working ok but I doubt it will cut the mustard in the summer. I will be going back to two trans coolers simply because they worked really well in the past, even when it is being driven hard, something I've noticed the single cooler doesn't do as well.

I am simply using the AEM FI/C 8, since I didn't want to mess with the TCU problems going to a stand alone. And I wanted the ability to have 2 maps, a high boost, high power map and a low boost, low timing map to run bad gas if premium isn't available.
I will get a dyno graph probably later in the week. Last night it was 10pm on the third night of the guys working 12-14 hour days, and at the time everyone was just excited to be done and buttoning things up, since I am supposed to be leaving today for FJ Summit.
The numbers were made at 16psi, but the guys talked me into backing it down to 12 psi to start, just because none of us really know what's safe for engine components and drivetrain.
The backwards formula used to roughly calculate hp was simply
{stock hp 212/(stock dyno hp)} x {turbo dyno hp}
{stock tq 300/(stock dyno tq)} x {turbo dyno tq}
I saw a 199% of stock hp and 210% of stock torque on the same dyno.
I know it's not perfect but it's going to be close enough for those looking at engine swaps to compare crank hp to ramjet 350's, LS 5.3/6L, 4/6bt's, 2UZFE's, etc since those are all listed as crank values.

EMS has a few different kits, you can check out their web page. My setup is a little homegrown simply because I wanted a few unusual things, so my cost isn't representative of what the kit will cost. Not to mention I bought all of the parts over time and I don't want to add them all up. Haha
I did 0-60 mph pre SC and got 18.xx seconds every time lol! So 14 seconds for 15-60 mph seems right on. With the 2.8 pulley it goes 12.xx seconds now. I bet yours now does 6-7.xxx seconds. That turbo system rocks, congratulations!!! Absolutely sweet!!

Haha yeah 0-60 is not the 80's strong suit, but it's an easy way to compare them without a dyno.
If you have a chance grab a video of like 10-60. The reason I used 15-60 is just because it was the common denominator in the 3 videos I wanted to compare. I grabbed all 3 videos and used iMovie to cut them from 15-60mph and the numbers so far are:
Stock - 14 seconds
Rear mount turbo - 12.2 seconds
Lilevo's GT35 turbo - 6.7 seconds
I would expect my truck to be right around lilevo's time (6.5-8) until he turns the boost up on his bigger turbo. Haha
So it would be cool to see where the TRD system fits in.

It happened to me while reading your post.
Congrats!!!!

Is there a post like lilevo's that summarizes what you've done?
What would really be helpful (I think) to us that are contemplating going down this road (and don't have the level of expertise you have) is a brief explanation/smmary of your decision tree and why you've done what you've done ie fuel management, tuning, etc..
I can't remember too, are you running that boost on a replaced stock head gasket or did you go with the Cometic/ARP setup.

Rookie,
I have a pretty detailed build thread. It will probably have the data you're looking for. The turbo stuff starts at post #386
I am running on stock new design head gasket and new OEM head bolts. I was not going to turbo it, but after not getting any performance gains from the Landtank MAF housing, I needed something.

Awesome work! I think you should start saving for this:

Okay thanks. I guess you feel pretty good about the head gasket to run it at 12psi, but if you had it to do over, would you still go OEM on the gasket and bolts?

I do feel good running the stock HG at 12psi, and 12psi for this turbo size and with this A2W intercooler is going be different than 12psi on a much larger turbo.
If I had to do it again I would have done ARP head studs and the verdict is out on what I would have done for a head gasket. In a perfect world the top of the block would need to be milled perfectly flat with a Cometic gasket. If the engine was out and I had the block and the head prepped I would probably go with the MLS gaskets but if the engine stays in the truck and the head is milled I would probably just stay with the stock redesigned toyota gasket and go with ARP head studs. I mean 12psi isn't really hight boost, we aren't talking about 40psi like the Supra guys are pushing.

Very cool build.
Glad it all worked out, good numbers! Bet it really woke it up.

but you had to dyno it at 16 PSI and take a video .. then you can lower ( I don't think you would do .. boost can be addictive )

Haha yes it can, but I am trying to keep this very tame. I don't want broken parts or a hole in the block, blown head gasket, etc.
EMS has mentioned that they want to strap a big turbo on to the stock motor and just see at what point things break. If there isn't any problem until 800hp, then sure I will go back and wring it out for what ever the little turbo can give me, but we are trying to be a little conservative until we have more information.
