Basicly a turbo cam version of the comp 280 magnum cam.

the 234-244 112 cam is a roots supercharger cam.
from previous twin turbo builds with the tpi intake, the best cams for power would be the summit 224/224 or the comp 268, both of these cams have pushed tpi toped turbo engines well into the 9's and just into the 8's

i know what would be ideal for this motor, and that summit 224 cam was awsome but like i said im willing to trade off some power for sound, i wont be racing the car enough to worry about squeezing every last bit of hp out of it

on a build with small valve truck heads and only a port matched tpi intake on a .40 over 350 that cam (224/224) made almost 700rwhp on 23psi from twin gn turbos. way more then i really need, i could literally give up 100-150 hp and not really care as long as driveability dosent suffer a whole lot

power numbers arent as important to me at the moment, more along the lines of if it will drive ok with the cam

this engine is an experiment for me as ive never had to tune anything at the altitude i am at 6,500ft above seal level. compared to being 0-200ft below is what im used to.

once im comfortable the altitude wont give me any headaches tuning i will be building an 227 afr headed 434 sb , with a single plane efi manfold for the real engine , paired with a set of gt3582r's or a pair of p trimed 66mm turbos

on this engine having everything perfectly matched will be much more of a priority
