Idler pulley question..
I want to change the idler pulley on my LS2 for a 90mm one. Does anyone know a part number or vender for a 90mm that fits ? 6 rib if that matters.
Thanks. |

Are you shooting for a little more wrap on the SC?

The very bottom of the page... its a double bearing idler which is intended for a 10 rib, but will work with an 8-6 rib as well. Part number is 916208 |

The ATI 90mm one is smooth. http://www.summitracing.com/parts/ati-916208/overview/
They also have a 100mm one. |

Metco Motorsports has what you need. Check them out. They have many different options.

Thanks guys. Ordered the ATI unit from Summit. Metco makes nice stuff but doesn't have a listing for an LS pulley so it got complicated quick when I spoke with them.:crazy:
I will install this with the 2.75 pulley and let you know how it turns out. |
Nothing exciting going on with my car this winter so I'll update this little fix.
No rush to install this since its winter here. Today I had nothing to do so into the garage I went. The ATI idler is a nice piece, but of course, like every little mod I do, a small bump in the road. The bolt from the stock idler is too short. No big deal, I just have to go looking for one this week. The 90 mm pulley is a very tight fit. No way a 100 mm would work. Its so close I had to move the hose clamp on the upper rad hose as it was touching. Once I get a bolt and finish I'll post a pic. |
You know Edelbrock has a new tensioner kit for better wrap and increased force on the belt. I was experiencing belt slip and this is their fix. It also comes with a new bracket to aid belt wrap as well and a new correct size bolt.

On left is the new idler pulley and right is the 2 3/4 eforce pulley that are going on. http://i1122.photobucket.com/albums/...psybyegpeg.jpg |

I have that upgrade since the summer. It is not the tensioner pulley I am changing, but the idler pulley between the tensioner and supercharger pulleys. Once its installed I will post pics.

Finally found time to get the right bolt and install this pulley. Its a super tight fit but definitely gives a little more belt wrap on the SC pulley. I have no clue if that little extra wrap will make a difference, but I am trusting that the Edelbrock guy at SEMA was right. Of course, a simple job still not completed as now the belt is too short. I will deal with that this week. Its a good thing I have until spring since its taken me 3 weeks just s swap the pulleys. :crazy2:
