Thats crazy

300 hp at the wheels once we are done

Holy God, that's amazing for a NA engine.... Good work, fellas.

Interesting - looks like what UL is saying he's gotten on a certain west-coast S2000 using a 2.2 engine. 271 on a Dynapack is approx 250 on a Dynojet, no? 290 to 300 crank hp, eh? This is the most I've ever seen on a N/A 2.0 liter. I didn't see a list of mods right off. I think UL's has i/h/e, cam gears and an AEM EMS?

Anyway,

follow the thread, its a bit more involved than just replacing engine parts with aftermarket

I suspect that when the specs are released we'll see its just a "hair" over 2 liters though since its tough to get that torque out of 2 liters without big time compression (non-streetable) or continuously variable cam timing. Additionally, the power peaking at 8000 rpm and droppign rapidly after indicates that its probably using stock (or near stock spec) cams on an oversized engine. I'm guessing somewhere around 2100cc, but even more kudos are due if its smaller - the smaller it is, the bigger the compliments, so to speak.

Why do I opine so? Well, because the plot looks remarkably similar to Mr. David Karner's F22 at 2157cc (270/186 since some tuning with adjustable cam gears). Congrats to the boys back east.

Considering that David's car retains completely stock Honda internals from the crank, rods, and pistons all the way to the cams, valves, etc. (only internal mods are a valve job, Ti retainers and cam gears) and required no engine building expertise outside of blueprinting clearances .... I don't have _any_ problem believing that a properly designed and assembled motor with good aftermarket parts could achieve the hp levels published in that thread - in addition to going well beyond it with more wild specifications as they plan. Even more impressive, Giles' dyno seems to read a bit lower than mine, so the results are even better than you might expect.

One more example that the F-series is far from maxxed out from the factory. I hear tell a few drag racers are going to be campaigning them in import all-motor racing too. Since those guys were making 330+ whp (dynapack) on B-series engines, I'm excited to see what happens then. Again, congrats to the boys back east on some great results. I eagerly await the specs. Don't spend your money on the JDM stuff guys, buy American (or Canadian)

I have one of the new Dynapack dynos that appears to be very much on a par number wise with the results of other brands of dynamometer. The engine needs some more miles on it before we start messing with such things as cam gears. The engine was originally a MY00 which had oil pump failure so the engine was rebored a little so its displacement is a little over 2 litres and the compression ratio was raised a little. Excellent forensic analysis Shawn! Can you read tea leaves too

Very Nice!
