DYNO 6port turbo
#1
well i dynoed my NA-turbo today
mods
its a 6 port NA s4 block with about 200K miles on it now.
im using s4 t2 manifolds port matched to fit the block, and an s5 turbocharger. i have an rtek 1.7 with 720cc secondarys and a walbro 255 pump. 3" exhaust and TID mod, and a SAFC.
i managed 231 hp and 220 ft lbs today at 10 psi, alot better than i expected. and it didnt blow up either !!
