10 Rib CONVERSION ???

SOCAL.M6.ZLE · 01-20-2024, 07:09 AM

Hey Team, Just curious who here has done a 10 rib conversion? Wondering how long it look to install, and where you are getting the belts from... Any down sides aside from the $1k cost?

Pretty easy upgrade, couple hours of work to do the THPSI setup. 10 rib isn’t needed at your power level but the LT5 tensioner is a nice upgrade for more travel and stronger tension. Will be good if you decide to crank up the boost down the road.

Thank you sir... I am planning on purchasing the Katech Dual Drop in Pumps, when they release the plug and play harness in the next few weeks, along with a Big Gulp.

With the extra lowside capacity, ill be running straight E85, and figured id also bump the lower pulley to add another pound of boost...

So when looking at lower pulleys, I saw the 10-rib kits, and thought that it might be time to upgrade... I am pretty sure, Ill be happy with 850rwhp +/- and wont need more than that...

I installed this DSX upper idler bracket with 8-rib belt, which eliminated any slip

Famous last words haha! Far be it from us to try to coax you into more boost….

You cannot just run the LT5 tensioner as the bolt pattern is different. TooHighPSI CNC cuts out the specific bracket you need out of billet aluminum. I have a pic or two in my build thread.

i might be interested in this since i bought the supercharger head spacers. 5 mm doesn't sound like a lot. But it makes a huge visual impact as well as all the wiring harnesses are significantly tighter, And obviously the belt will be a close fit also. So a tensioner that has a bit more throw would be nice. I'm sure it will help with temps though. Today, February 5th it was like 93...

You should start a new thread about that since this one is about the 10 rib conversion.
