New belt=Less boost

[jivepepper]

After shreading the belt monday morning. I replaced it with the same size and brand. The only difference was that this belt had a slightly different pattern to the cogs on the ribs. It looks something like a goodyear gatorback, but its the by Dayco The box was faded and, I think it was like an older version.



Well I was seeing about 14psi at the top of third according to my boost gauge. Now I'm at about 12.5-13 at the top of third. I did have the one IC pipe off so I'll check there for a small leak. I want what I had before. The vacuum is the same. I need it to be the same for the 7th Dammit!! Because I'm going to the track for the first time ever. What's that **** people spray on there belt at the track?

If you think you're getting belt slippage, I would check for rubber dust in the engine bay. I thought the gatorback was a good belt, maybe try to get another one?

you have a dayco polycog belt and they grip better than the regular belts... its ilke a cheap gatorback... i think you either have a slight boost leak or your gauge is going bad if there isnt any belt dust anywhere....

I never ran a gatorback. I only commented that it looked like a gatorback. I ran a polycog bought times. This one just looked a little different. I think it was an older version because the cogs are spaced farther apart and the box looked old and faded.

I get belt slip but I still got between 13.5-14 psi. Now about a pound less.

If you use any belt dressing, be careful to not overdo it.

well I hope this fixes your issues. Did you end up checking for leaks?

Thanks. Not yet I will after the new belt install.

Good plan. I'd keep the Dayco belt + a 1/2" drive (or 3/8", depends on the year) rachet in your trunk, just in case you shred the gatorback belt far from your house.

I probably will but it still takes 2 peps to put it on.
