Why pick 168 over a 172 or vice versa?
I am trying to make a decision about which pulley to get.

I understand LTs make the car lose some boost, but how much? Is it negligible? I was thinking to get the larger pulley to make up for the boost loss (172 instead of 168).

Is the 172 a plug n play pulley set like the Renntech/Kleemann 168 set is?



PLEASE HELP ME MAKE THIS DECISION!

172 because the car handles the 168 so well --- a few mm larger should be fine... but to get full benefit you need a tune.

I've already done a ton of cooling and about to add a trunk tank so i figured I'll run a larger pulley. 180-190.

Sorry Craig, I already got another pulley on the way but will hit you up in case it goes south.

Is the 172 pulley kit plug n play? Or is modification necessary?

The 168 is plug and play correct?


Thanks in advance...
