5.5t for indoor?

[Gavin9]

hello all, I raced over 10 years ago but havent touched a buggy since so am pretty much a newbie but cant wait to get back involved... recently bought a losi 22 and with it got a nosram matrix evo esc and a Losi xcelorin 5.5t Motor...I was told at the time that the motor would be fine for indoor racing but as I research and look around the forum I read lots that I should be looking at 7.5t upwards? Im not fully aware of all the differences in motors. I am planning to race at southport in the new year and was just wondering whether i can/should race with a 5.5 or whether i would need a different motor.

thanks in advance

Gavin
