Everyone always fights over the best intake setup and most people say C&L with 75mm is the best for NA or SC or Accufab with 70mm is the best for NA and 75mm for sc
but no.....
Accufab with 75mm is the best for al applications s/c or not
Dyno done for all setups prove this on a guys 03 with exhaust and pullys only....

Stock run was more on plenum + 75mm set up so this shows a little confusion on GAINS.... but overall hp/tq shows
ACCUFAB + 75mm TB=BEST!!!!!!!!!!!!!

how you figure? it clearly shows that the 70mm tb produced more peak hp and torque AND more hp and torque through the curve. As a matter of fact the 70mm produced strong gains through the whole powerband whereas the 75mm not only didn't produce as much peak power - but it virtually made no real power over stock until after 4000 rpm.

So ummm...

ok now i am confussed again....... he has the same car and set up for both test. But the peak is the highest on accufab plenum + 75tb, i figured his stock runs just happen to run better with the 75mm runs so it is less noticable of increase .. compare both test dynos on top of each other...

are you saying accufab plenum + 70mm best for na and 75mm for sc or 70mm for all applications?

mdvaldosta

70mm for NA applications. Look at the before and after numbers IN THE SAME ARTICLE, not hp numbers for between the different articles.
