the stock tb is not at its absolute limit in terms of flow, it can allow for increased flow. an aftermarket 70mm tb on a ported stock plenum can get you 5 or 6 rwhp peak. not too shabby really. just porting the plenum aids in reducing a restriction, which gives you modest gains.
yea i agree with yall on that you can get more out of the stock plenum but i just dont see why just go with a aftermarket not that much more and you will see better gains
well, its like this. i paid $75 for a used 70mm tb, and ported my stock plenum. i think i got about 5 horsies out of it. an accufab setup costs about $400 for perhaps 2 more oversized mules. $325 just ain't worth it to me for the 2 extra meat bags. for someone looking to get the absolute max, then by all means. i'm looking to be fast on the cheap however, more a sense of pride by doing it that way for me.
