However, I really would like to know what makes it so appealing to have Hyper7 as well as Hyper SS with .28 engine.
Would more torque mean better buggy performance on hilly drives or grass etc. and what does more engine rev mean?
Thank you for your inputs.
A .28 engine will usually have more torque. So acceleration may be a little faster, but that depends on the engine. There are many .21 engines that are more powerful than .28 engines, so it really depends on the engines you're comparing.
Usually a .28 engine won't run as fast as a .21 engine will. Say a certain .28 maxes out at 30,000 rpm and a good .21 maxes out at 40,000. You can use a clutch bell with more teeth with a .28 engine since they usually have more torque to get extra speed, but I don't think the bigger engines are any better in a buggy. People usually put them in monster trucks so that they can do wheelies easily.
Simply: .28 usually has more torque, so quicker acceleration while a .21 has a higher rpm range and (usually) a higher top speed. I don't think the extra torque is worth the extra fuel that a .28 will use. Most people use .21 engines in their buggies.
