better acceloration

[grim]

Hi i am every new to all this so please be gental.  I was wondering what would give me better acceloration a 13T or a 15T clutch housing on a 3port 21 ho-bao?. 
Also what is the port all about (what does it mean?).

I have only had these cars since christmas so still in virgin teritory.  Istarted with ansmann virus (bad move keeped breacking) then got hyper 8.5 rtr MUCH better, lots of fun.

A smaller clutch bell will give you better acceleration and a bigger clutch bell will give you higher top end speed.

Here is a little write up on how nitro engines work which details what the ports actually do Nitro Engines Explained
