After doing some research I've decided to get the sc61. My only question is about the exaust housing size? If I were to get the .63ar, how would the top end fair? I would be using the T350 76 trim exaust wheel (stg 5 wheel). thanx

I guess it would help if I tell you which motor huh. crvtec, 9:1 comp, 3"dp, Nu-image mani

 

it wouldnt be that bad, maybe you should ask yourself, what is the sole purpose of this car?

drag car?
street car??

if it were up to me id get like .82 laaaaaaaate spool..helps low end traction probs

 

street car

 

yeah I would agree with the street car.
