Project Supra on Modified By KC’s Dynojet 424x, ready to spin some madness.
Project Supra: Part 10 – Dyno testing – we hit 800 WHP!
I know that in Part 9 I said I was already working on getting this next part of our Project Supra series together, and that it would be soon released on MotoIQ. But here we are two months later. Forgive me.
I was telling the truth, but at the time I wrote that I also did not know I would be given the opportunity to cover the PRI 2014 show, which took 52 pages—that’s like 10 articles’ worth of content! But now that I’ve got those out of the way, I’m excited to bring back this “little Toyota that could” to you.
In this article you'll see a record amount of dyno graphs, not only of this car with its different boost levels, but also of other interesting cars I found while trotting around the Modified by KC stable on the days I swung by.
In case some of you West Coasters have forgotten, it’s winter out here in the Midwest. And it's cold here in the Kansas City area. Actually, two days ago as I type this, it was 70F and tomorrow we've got a high of 38F with some snow. So the temperature is really all over the place. In any case, this is how the Supra has been spending most of its time since November.
In case you haven’t been up to date with our Project Supra, our goal was to hit 800whp. We started this pursuit with a built engine featured in Parts 1-3, some bigger and badder parts like turbo, exhaust and intake components featured in Parts 4-5, a stout intercooler featured in Part 7, and a nice fuel system featured in Parts 8-9. In order to make it all work harmoniously, however, we needed an engine management system, and that’s where the AEM Infinity comes in.
The AEM Infinity has been steadily growing in popularity in nearly all forms of racing, including drag racing, road racing, and drifting. It features Motorsports-grade, weatherproofed hardware, and a CPU speed of over 400 million instructions per second (MIPS). It’s truly a fine piece of hardware.
If you read through our PRI 2014 Part 1 coverage, you may have noticed that AEM is continuously expanding its plug-and-play harness applications list. AEM started with the E46 M3, which we installed and tested in Project E46 M3 Part 6, and then they made one for the MKIV Supra, which is pictured here. Lucky for us!
AEM’s PnP Infinity harnesses are now available for some Nissan, Honda, Mitsubishi and VW models, as well as Porsche 996 and 997. AEM’s also just released a PnP harness for the 2003-2007 USDM Mitsubishi Evo VIII and IX.
Also pictured above are some optional AEM Infinity sensors, including sensors for Exhaust Back-Pressure (long one, upper-left), Fuel pressure and Boost Pressure (upper-left), Exhaust Gas Temperature (upper-right), 0xygen/Lambda (right), and Intake Air Temperature on the lower right.
