Stock vs stock 2013 on B5 and 2060 on Soeed neither one pulls on each other, B5 has more snap off bottom and B5 gets better mileage...on the dyno they put out nearly identical numbers....thats the facts from true side by side testing...The Speed does have less off the line punch and a smoother feel, but adding a weighted flywheel to the B5 smooths it out just the same....
Well let's say that it would be hard to believe if no other engine manufacturer
would come up with something better than V-Spec/Speed combination since the basic engine has been out for ages.
In my opinion OS is a good engine brand but it's not superior to Nova or RB etc. Main advantage of OS is it's carb and the overall tuning meaning it can be pretty much off and still run OK. Most of the other engines out there have narrower window and there for can be considered "harder" to tune. If you say you can "out tune" most then who cares and what does it mean in general ? Absolutely zero as you can't run around the world and tune the engines can you ? I can tune my Alphas for +10min but still it does not mean that everyone can do that. So the package needs to be so easy to use that majority of the users can feel them selfs as a good tuner be it the case or not. This is the advantage of OS + the (stock) Speed can make 10min where say 90% of the other stock engines can't. In many cases you can have 10min or close with +4 and with B5. Only issue with B5 is that it won't last more than few gallons on that +10min tune (kind of a vspec syndrome) and +4 can't reach the tank times as reliably as OS. Now keep in mind this is with normal racers and not any "PRO's".
Now what this leads to us: it's more how you use the gear than what it says on the cooling head or block. And what is funny is that most of the guys who argue these things can't either drive so well that they could take the advantage of something that can be seen only on dynos nor tune their superios engine for +10min tank times even they claim to do so in Internet
So have fun racing and leave these debates to the internet experts
