GRP .28 Tuned!
Guys, I have just gotten the new Mugen 6T and was thinking about dropping in a GRP .28 tuned mill but I don't have any experience with this line of motors. For those that have actually used this motor please provide some commentary before I pull the trigger.
Be brutally honest about your likes and dislikes. Also, this is the promo kit version so it will include the header and pipe.
Thanks guys for the input!

GRP.28
I have ran the GRP.28 for 2 summers in a x2 crt. Engine has the smoothest power I have ran in a .28. Pit time average about 8 1/2 min. with 7.0 restrictor p3 plug Byrons 30%. I have aprox. 7 gallons on this engine and still runs very strong with good compression.

I'm running the tuned .28 in a 8T 2.0. You probably want to change a few things to help tame it and get better fuel ecconomy. Run the 6.0 restrictor, the lightest clutch springs you can get and, gear up 2-3 teeth on the clutch bell. I also run run the GRP pipe.
The preformance is about the same as the best 21 engine you can find with this setup. I had ran a 16 tooth bell for a while and it was very smooth and fast. It was also a little harder on the clutch shoes. 2 weeks ago I switched to a 15 tooth bell and I liked it a lot better on a high traction surface. It was getting 8-9 minutes of runtime on a tank. I would also recomend runing the Dynamite Maxlife clutch shoes.

It, and the almost identical Ninja .28 were the kings of .28 nitro engines
