Im thinking of getting a crank pulley, I was told either a 168 or 172 given my current mods since 180 would be putting my motor at MAX. However, I hear Renntech and ASP make the best quality without risking them flying off but they're also $1000, anyone also recommend a good one for a more reasonable price?

That's about the going price. I picked up my 180mm ASP pulley for $900.

Shardul sells one for 850 with a pin kit. I wouldn't run one without it pinned.

Asp and installation is key!

Worth the wait

Why not just get a SC pulley?
Less weight, easier to install and less risk.

lol - as long as you're right on key...

What's pinned mean?

What's the installation key?

I already have one but crank pulley gives more power and boost

Ditch your current sc pulley and get the clutched 77mm sc pulley and your done.

vikingdiesel

Really... 77mm willreally help over the 83?

I meant installation is most important thing with a crank pulley. Most often pulleys fall off because of bad installation.

I've yet to hear of a single failure of an evosport crank pulley. My car had one installed by the original owner 9 years ago at 20k miles. Now has 86k . Its a 180. I noticed a few used ones for sale on eBay recently.

Where do I get the evosport pulley?

Google how to pin the crank pulley. If you don't want to do this, you should not install a pulley.

My car has had a Renntech pulley fitted since the day it left the dealership. 62,000 miles later it is still going strong.

Supercharger rpm specs say that is like moving from a 168 to a 180 crank, which is a 2.4psi increase.

I remember your post. You have a good set up. With your mods you can run a large crank pulley. 190+. You can add a 175 to 178 in be in the same range as a 190-95 crank pulley. Keep in mind 99% of the people with a 84mm sc pulley don't have the cooling and fuel mods you have. I would go 172 atleast. But a 175-78 would put you where you should be. BUT I wouldn't run that boost without pinning the pulley. Don't even consider it. So if the thought of drilling a hole in you crank makes you feel sick then just change to the 77 mm clutched.

Sorry guys but what's pinning the pulley mean?

evosport is out of business btw

Bro 180mm CP all day. Just make sure it's pinned and have someone who knows what they're doing install it. Ziveli!

menace2sobriety

I have the 77mm clutched pulley on mine and it goes hard

Boost rises to ~14psi
