I understand there are different impellers for the Gtx-4 a friend put one of mine on the ground a couple of years back. I took it in and asked and the dealer said they had one that would give it a littler additional speed all it did was make it sound different. So now the same friend just left but before leaving he put the other sled on the ground. So before I do it again I thought I'd check with some guys that might know if there's a faster impeller available.
Thanks in advance.
