In my opinion the 3 P R is the perfect rtr engine, it starts easily, ideals well, gets 7-8mins using standard 8mm restrictor but lacks punch which is what I need. I know a few guys who have run 3PR ,5PT and 7PT they seem to like the 5PT best as it offers great punch and more than enough top end. I should have saved a wee bit longer and purchased a 5PT.These Go engines are extremely tough.
I think that's a bit hard comment. I'd consider the R-Spec to be fully breed race engine not some RTR stuff. Also the first gen r-spec is a bit weaker than the newest gen that I currently run but that's what we call R&D
The engine selection depends greatly on track conditions and car you are running. Our team drives with 5pt on buggys (except me) as it's best match to our tracks and they are also looking for that initial kick. I'm satisfied with the r-spec and with M2C clutch it's great thing to drive. I also run the 5pt on my truggy and happy with it so there's plenty of pwr packed in that engine. If you compare r-spec and 5pt you can clearly say the 5pt wipes the floor with the r-spec when speaking or low-end punch.
For cheap alternative get the 5pt sleeve and make a frankenstain R-spec
