Roughly...yes. But they are still for sale right now, so.....

 

well ill let you sell them before i flood the market w/ them...jk.
haha

 

haha, i love it!!
i put the atx tb on and didnt have much trouble except for the uneccisarilly large battery tray in the way.
i kept the atx butterfly spring on there, and so far i love it. it does take some getting used too, seeing as i have chirped 1st, 2nd, and 3rd for about an hour now. thanx soo much guys.

 

i have a wierd question could i just get my mtx tb and take a dremal to it and make it as big as a atx or get a atx and make it even bigger?

 

No...No you can not...Well you could but you butterfly would be to small and you would be leaking air past it by 1mm all the way around if you bored it perfectly all the way down letting way to much air in and your car would idle crazy insane high. that is is your as persise as a lathe
