Tweaked it a little more today. Stopped at 14 psi.

377.60 RWHP @ 5641 rpms376.00 LB/FT @ 418514 psi @ 3533

Bone stock never been touched KA24DE with 113,820 milesPhatKA-T turbo kit (SC50 turbo)PK fuel systemPK S13 ICPK modded engine management (AEM EMS)

Dyno runs on Mustang MD1750 in ground dyno @ Sound Performance.

Driving it is just plain stupid. Anything over 4000 rpms in first or second gear just shreds the tires. Never went for third gear before the weather got crappy. The customers are coming out tomorrow to give it a test spin prior to pulling the kit down for coat, polish, paint and jigs. I will assume that he will post his opinion on how the car is running.

Damn...I think thats a record for 14 psi. Whats AF's were you running and what octane for those numbers?

Not to be a ****... But how much was the setup that made that power?

AF was 11.25 VERY conservative. Timing at 14psi was 18 degrees (I am thinking very conservative) Timing is set up for premium fuel (91-93 octane). Knock sensor reads NO KNOCK.

Yesterday while tuning the timing table, we had timing a little more aggressive and were running 93 octane. We had knock registering around 1.2 volts on the AEM EMS. We backed the timing down till there was NONE registering.

Because we are using a manual boost controller and had no idea what might happen to boost when we adjusted it, and to be on the safe side, I put in about 2 gals of race gas (all I could fit in the tank that was nearly filled with 93 octane) and continued dynoing. The race gas was just insurance against anything that might happen. If anything, the race gas is taking power away with our conservative timing numbers.

Once we are finished figuring out how far we are going to go with this car, we will fill it with 91 octane and make sure that it absolutely safe to drive at whatever boost level we decide will live for a while on the street. I think that we are going to let it leave the shop at the 350ish RWHP level for premium fuel.

The great thing about the AEM EMS is the safe guards that you can program in. We will be turning on Knock control which will pull timing and add fuel when ever it sees KS voltage over what ever we determine to be a safe level. We can also have the AEM EMS setup for O2 feedback correction which we can program to add or subtract fuel based on what the wide band O2 sees and what AF ratio we have programmed into the VE table. Normally if we do set it up this way, we will only allow the EMS add fuel. If the WB ever goes bad, we don't want it pulling fuel out. We will also program the EMS to turn the injectors off if boost level that we program in is exceeded. We also set up the EMS to loop log internally any time boost is being made. This is kind of a tattle tale that will allow us to see what is going on when the car is outside our control.

Thank you. I am really happy that all the hard work that went into this project has resulted in something impressive.

I know there were a lot of opinions when I stared talking about my ideas on FA when it came to stand alone engine mgt. I really wanted to be in control of EVERYTHING that the motor was doing so this was the route I took. I wanted to make sure EVERYTHING that went into this car was top of the line and there would be no need to upgrade anything for a while for this customer.

I have to admit that I really am shocked that things went so well. I am shocked that the engine was so responsive to boost. The BHP is almost trippled over stock and I havent even put a full atmosphere thru the motor yet. I am pretty sure that this motor would put 400+ WHP down if I turned the boost up to 16 psi.

I dont want to hurt anything on this motor so I am being very cautious and trying to keep everything reasonably safe. I would love to push the motor harder but dont want to blow the head gasket or crack a piston or throw a rod out of the block. If this were my car I would push it to beyond its limits and try to extract as much knowledge out of this motor as I could as the power increased. I will eventually do this with one of my 240s but it will be a little while. I did it once already with my 5speed 240 but with Nitrous and no engine mgt or datalogging. I ended up breaking a ring land on a 250 shot :)

I dont mean to try and call BS on this, but this is quite a feat to accomplish. If you could, post up some graphs of hp/tq crossed with boost for us. I would be very interested to know about this kit as well, I am wanting to take my current s14 to a full race application and have a ka-t daily to drive.

how much was the AEM AMS? does it **** with all the factory settings does it only allow you can control fuel and spark? also what size injectors are you using? that is insane power for a stock KA running only 14 psi.

the ems is a stand-alone that uses the stock wiring harness

Wow...I almost can't believe that. That much power on that boost? It hurts my head...and makes me wanna find out more about this kit and turbo. :)

Well I'm as curious as you guys are. The answer to some questions you can find out on his website, Im pretty sure he runs the same manifold and downpipes as the ones shown on his website, also he has the information on the injectors, I wonder if those are the same ones used in this setup, There are prices on all those items there too except for the Turbo,i ntercooler kit, and the EMS. I hope he posts here something soon, im going mad.

VERY impressive numbers from a stock KA-T at 14 PSI! congratulations on a great KA-T build to say the least. I'd love to see the hp/torque/af curves if you got them.

Sorry guys, I am still here. Here are dyno graphs. The MD Dyno software really sux so I cant really get too much usefull info on one sheet so I have to show two. The DynoJet does a much better job all in one shot.



Power (red) and Torque (black) are on the scale. Boost (yellow)scale is hard to read. It starts at zero bottom line and goes up 3 psi per line. The Dyno boost sensor reads 1 1/2 psi high so we only use it as a reference. Both the AM boost gauge in the car and the AEM EMS showed 14 psi on this run. RPM (blue) can be seen on the next sheet.



This one has the RPM reference on the left.

Full description of turbo kit:Manifold is 16ga mild steel with 1 3/4" runners, 1/2 thick flange. Designed to work with Tial 38mm external WG. WG is dumping to atmosphere. SC50 turbo is 50 trim w/ stage III wheel T3 turbine inlet 5 bolt outlet. Turbo is bottom mounted. Down pipe starts 2 3/4" and quickly opens to 3" and has flex section. 3" test pipe into Apexi Dual exhaust. MBC from AMS controlling WG running single port. Evap and EGR needed to be removed for fitment. AC and PS are working and in stock locations.

Intercooler description:Garret core rated to 400 HP. Cast end tanks. 2 1/2 intercooler piping from turbo to TB.

Fuel system description:Extruded aluminum fuel rail stock machined to accept top feed injectors and bolting to factory fuel rail mounting points. 6AN lines and fittings from stock feed to rail to FPR to stock return. Stock lines still used from front to back of car. Walboro 255L HP pump replaced stock fuel pump. Aeromotive AFPR mounted to fire wall set to 55psi base fuel pressure. Liquid filled FPG mounted to regulator. 50lb high impedance top feed injectors.

Engine Mgt description:AEM EMS stand alone. Replaced stock computer. Uses factory wiring (mostly). Reads factory TPS, ECT, CAM, CPS, KS. Added GM IAT and 3bar MAP to replace stock MAF. Basically the car is converted from MAF to MAP. AEM UEGO controller / gauge (wide band 02)

Thats about it. I believe the good numbers are a result of short fat runners on the header, good turbo selection, smooth straight DP, external dump on WG, lack of MAF restriction, and excellent tuning with an excellent engine management system.

I am not a sponsor here and should not be selling things here. For more info you can email me, visit my web page, or call me at the shop.

Now that the car is complete, everything is being pulled off to be jigged up so we can duplicate this setup and everything will be polished, ceramic coated, or powder coated for final pictures and assembly.

The turbo kit to end all turbo kits if these results are duplicatable.

No doubt, a very good topend kit.
