   does anyone know what size bore each branch on the manifold is?
   i.e
   
   supersprint
   raceland
   janspeed
   gmc
   piper

   tbh if you go for the biggest then your bhp wont be so restricted, for example the raceland the max power that should go through it id 150bhp from what i gather so the larger the bore size the more tuning you can put in i think is the principle but if you go too large for your untuned engine there wont be enough back pressure

   if you look at vtr180's thread you'll see he found out that racelands are good upto about 170180bhp so hes changed as hes running about 186bhp i think on Tb's
