I think they are close in runtimes and just to put it out there, you cant compare to what the pros run, they do not run stock engines

I think the +4 gets the nod in the runtime department.

The OS Speed gets great mileage but its primary purpose seems to be to haul the mail not getting extended runtimes...it just happens to do both

The rest of the RC world was forced to start to focus on mileage by the V-Spec and Speed and in doing so I think they have eventually surpassed them. In talking to Ed Bridges (EB Mods) he said they do this by using a smaller crank opening which in turn gives less HP. This was during a conversation about why the GRP engines were capable of such impressive run times.

I guess tune and driving has a big part of it. I have a speed and I have been getting better milage than the 21-4.

I've seen Ryan Lutz in person go 13:30 on a tank with the SPEED.

Last time I saw Lutz (speed) run with Drake(plus 4) at Rev, Ryan had to pit once more than Adam in a 40min main. (Ryan was on, he still won) They are close, but the plus 4 is good for an extra 40-60 seconds.
