hi,

i have just bought a new rad setup and ive got the fan off my old setup left.

is it worth mounting this as a puller on the IC? I havent chopped my bumper much and thought it might help airflow, and i have room behind the IC for a fan, here is a pic:

 

Only in rare cases is it really necessary, like if the front bumper wasn't designed to ingest in the air needed to support the turbo system. In your case, with a honda, it is not necessary, as it will block more air than it will provide if it were simply left open. Perhaps cutting some of the black plastic of the grill will help more if you're looking at this as a concern

 

okay, thanks for the advice. I'll monitor IAT's and if theres a problem i'll report back.

 

There shouldn't be for 90% of the applications used if tuned correctly. Especially on a Honda, really.
