RBs are just awesome engines, the only thing i would complain about is the price, but they're worth it.

The GRP is a great engine, but just like the old Ninjas, you get one and it could be the best engine you've ever had...If you're lucky.

I vote RB. I know that they are a little more expensive, but they last. I had a GRP, and I popped a rod after 1/2 gallon. It may have just been a bad apple, but it ruined my taste for the brand. I am on gallon 4 with the RB and it still pulls strong.

we run both the GRP and RB engines like em both...one RB in my sons 8t will be on its 3rd season coming up and never opened up.. the GRP .21 was the 1st year last year, and also ran great.. run time was 10 to 12 minutes..both have plenty of power and reliable... tie here...

Both are great lines of Engines go with whatever support you might get at what track you are located at or hobby shop that carries either

I've got a .28 tuned GRP sitting on my workbench NIB for a project I was playing with - sort of lost interest (sick basher buggy). I'm sure we could get it delivered for a good deal. PM me if interested.

RB C6 in a buggy, you better hold on to the oh $h1t handle, Insane power! I run a C6 in my 8T 2.0 and ran a 10 min main without a pit and had enough gas to run another 2 mintues easy on a wide open track.

its gotta be the rb c6 the grp is nice and smooth but there is a point were u can get to smooth down the straight and any really tight bits the grp gets shat on because it doesnt spool fast enough to get going

I had a C6 before. It was great! when I got to the track it would be first to start and last to finish and I never used full trottle.

i have had both these engines, and i definatly vote RB!

the GRP looks like a gem, but for me it stopped there.....
it was difficult to break in, it would rev iraticly, and i always was chasing the tune........it did have a smooth power band but wasnt overly poweful......iv seen more than one of them get smoked down the straight like it wasnt even fair by an x-tech.......

the RB is just the opposite........not much bling, but is verry consistant, easy to tune once you get it right, but the S7 isnt a powerhouse either and is smooth as well......
