      It hasn't progressed much beyond a basic layout I want to explore. But I am very confident we can develop a manifold configuration which places the turbo favorably. And that means a "hot parts" kit...

      20psi is a good basis for those calcs. When powered by E85 exhaust, the current-model MixedFlow F21T can do only a hair more than that.

      Speaking of tuning above the MAP sensor's gamut, I thought Id post some interesting graphs that document another dynamic of Maestro-based tuning at this level. Because along with being "blind" to...

      I'd take the fuel rail pressure up to 5bar -- and then closely monitor your fuel trims (corrections) and Lambdas. Your tuner will have to keep airflows within the limits of what 550s @5bar can...

      Everybody likes a video. Well, at least I know I do.

      Have you data logged the fueling corrections at WOT? Are you seeing active values? Do they remain active and changing all the way through the pull? If so, what then are your actual Lambda values?

      I'm not sure I'd call any of those three approaches "ghetto". But lacking the 3bar capabilities of more modern cars such as the Golf R, "forced" boost duty values are all you have -- or ever will...

      If all you're trying to do is force boost above the sensor limit, and your turbo is capable of that much output, you adjust upwards the values in the boost duty table. All of them, across all...

      Thanks for the candid feedback. As you may know, we're developing a turbo hardware kit for the 2.5L engine as well, and solid info on installation challenges is really valuable. While our kit will...
    10. FrankenTurbo MixedFlow F21T E85 fuel dyno testing

      Last winter we wrapped up pump gas testing of our MixedFlow F21T hybrid turbo with a solid 300whp result. As soon as the DynoJet's rollers came to a stop ForceFed's Ed Woolsey suggested we build the...

      Toyota MR2 Spyder electric power steering modification

      The electric pump from the Toyota MR2 Spyder is working very well. Here is a short video we took just after powering it up. Aside from a couple of easily-sorted leaks it is finished. I had been...

      I wonder what became of that prototype throttle-body spacer they were working on at USRT. It seemed like a cool idea when they sent us a sample:

      Clearance around the manifold runners is tight, making it a challenge to get a tool onto the 13 manifold stud nuts. But with patience it will go in. Thx

      Yes. Any generic high-flow exhaust manifold would be a much better choice than the stock unit. I'd thought the Greddy kit came with one but I guess that wasn't doable at the $3000+ price point.

      Understood. I think we've sufficiently whetted peoples' appetites. So we're shortly going to begin laying out a manifold and up-pipe adapter for the stock exhaust. How will we be doing that? In...

      Here's where things get more awesome-er. Or where they might simply fall apart.

      This new motor has no power steering pump. The majority of 2.5L-engine cars have steering systems with the powered...
