Has anyone moved from a 175/180 pulley to 168 mm and recorded the IAT changes ?

I have added upgraded HE with meander pump and still constantly breaching the 140f threshold causing fuel dumping at about 4800 rpm and losing power at the top end. Was considering sizing pulley to 168 and maybe getting more power.

i dunno but should be drastic... my friend had a 180 and it would shut down ALL the time until he upgraded his HE and pump
I have a 168 and never shut down with repeated runs in the Vegas summer - my HE and pump were stock at that time.

I go over 140 all the time with the 180mm...but then again I went over 140 with the oem pulley as well on the stock H/E.

Done many things to reduce intake temp but the only thing I cannot mod is the local weather!

Just wanted to see if someone that has made the change can share the info. All I need is for the temp to fall another 8-10C ,I think it will be good

For sure it will. I made a post a few years back on AIT of the 168 with tables. You will have to search for it
