Hi folks,
I've been chatting with a guy who has developed 931's for the track and has quite a few years of experience under his belt (and that's just on 931's). Here are a couple tidbits I thought would be interesting to the group-

931 driveline losses come out to ~19%

With 1bar boost, intercooler, modern EFI, and ignition, he's seeing a solid 258hp (210rwhp) on 93octane (US measure). I believe this is on stock pistons and a stock k26 too. Good to hear, this is just about the number I'm shooting for with these mods. However, he reports that the stock clutch can begin to slip at this level.

Even at 210whp, it will leave behind a 964 without much work.

well 210whp and 2700lbs is a good mix..

Im looking for about 210 at the flywheel with stock CIS injection. That would be intercooled/14psi.
