More Dyno Time

We did get the STI back on the dyno, and temps were much cooler than during the summer. But still the STI wouldn't make any more power than before. I tried some different approaches -- lower boost with more ignition timing, for example -- but didn't have any luck. I was comparing the dyno results with a recent STI I tuned that featured a 20G turbo. (The Tomei ARMS M7760 is similarly-sized to a Mitsubishi 20G.) The Tomei turbo spools significantly faster, but seems to have less top-end. Is the turbo holding our car back? Or is something else going on? We're going to find out.

I also managed to take some video of the car on the dyno. There's not a whole lot to see, but you can get some idea of the noise and of the car straining against the straps. Off the left side of the screen are two high-velocity fans, which make a lot of noise on their own.

Finally, something more blog-related than car-related: The FTC has released guidelines about disclosure in online media. Specifically, it's trying to give a little more clarity to bloggers their relationship with advertisers or sponsors. I thought I'd use this opportunity to talk about the sponsors of this blog.

Basically there's only one sponsor: Mach V Motorsports, my company. At least as of this point, all the parts featured here were purchased by the company. None were donated by other companies. We sometimes get some discounts on parts that are intended for the shop car -- I think the hood shipping was discounted, for example. But aside from that, every part was bought and paid for, and none of my suppliers knew I would be discussing the product on this blog.

In the future, assuming the popularity of Mach V STI Blog suddenly shoots up, companies may fight for the right to give us free goodies to review. (Oh please, oh please.) When that happens, I'll be as clear as I can about parts that were given rather than purchased by us.

I do hope that this blog prompts people to go to our web site -- www.fastwrx.com, remember! -- and buy things. That's the whole idea of the blog.
