Magnacharger rear 10 rib question

[1stGXPmaggie2.3]

At what boost level does it start to slip. Was told by a pulley supplier that it will begin to start slipping after 10lbs. Want to get a second opinion if anyone knows.

No way for it to slip unless it's too loose. Mine (1900) has a "gear" type belt on the rear.

As for the 6-rib front belt, I never had slippage when I had a 2.9" pulley on at 10psi before my cam

Hey norm why do you have a picture of your rear tire in your sig?

I'm at 11 lbs currently with a 6 rib front setup. I have no belt slip(yet).

Im running on the front an innovators front overdrive 8 rib setup, but was told that the rear 10 rib will slip after 10lbs., but might of been some misinformation about the slippage.

"Gear" type belt on rear??? did you modify before putting in? I have the 10 rib belt as sold to me..info?

My mistake. It's a 10 rib. My mind is playing tricks on me in my old age.:om: Well there's your answer switch it to the "gear" (or whatever it's called) type.

I know of a local GTO with a cog rear setup on his 1900. He is using a 6 rib front setup (3" pulley))but I'm not sure how much boost he is making. Dynoed at 650 RWHP.
