just wanted to know if any of you guys that have a procharger in your truck pinned the crank or changed pulley? Also if you have videos of your procharged truck driving in the street or at the track please post them up... Thanks..

 

Def pin the crank. Not only with procharged trucks, but any Blower app..

 

thanks for the heads up mangled03.... you've been of great help since I'm new to this and have no knowledge about it... I appreciate it

 

Yeap, its a must with a blower.

 

what do you mean pinning the crank?

 

whats pinning the crank??

 

You drill a passage way where the crankshaft and and crank pulley meet, then install a pin in there to prevent the crank pulley from spinning on the crankshaft.

The blower at high boost will create a lot of force on the crankshaft pulley and it will slip under high load, reducing boost.

Crank slippage= BAD , and bad for boost.

No crank slippage= MORE BOOST !

 

not to mention you could damage the crankshaft.....

 

Can you explain how can the crankshaft be damaged with the pinning kit. I don't want to start anything just want to learn.

 

Not damaged by pinning it, it's damaged by the pulley spinning on it.
