RE: Dynamite Big Red .28 in a XL?
If its the 6 port it will scream on topend i had the xtm457 6 port,
basically the same engine internally and it was excellent allround,
i also had the sh28 3 port in a 2speed monster pirate and it would lift the front wheels in the air, but suffered from little topend
although i run the xtm 457 in a extended madforce it was still too much engine for it,
