Default School me guys...

So I have the 2.8 pulley on my car. Mods are in my signature, here my problem. I guess from the sheets from the dyno and from what they guys were telling me is my belt is slipping. I have asked people how they fixed it. I was told about changing the pulleys, but what ones? All of them? I changed out the idler but it was to big so I had to put it back. Any ideas on how I can make the belt grip??

Buy a "belt wrap kit" which puts more tension on the belt. Or people have cut grooves/slits in the MPS pulley to help it "grab" better.

That kit will help quite a bit but if you want to completely stop belt slip, try some cogged pullies.

Farnsworth's "cog" setup is a show piece. Nothing more. You will get better results with that belt wrap kit, or even an 8 rib setup and still be cheaper.

Yeah, I plan to get the 8 rib set up and wrap kit next month. I hope it helps, should I go up a pulley size also.

I'd wait to see how much of a difference the belt wrap kit makes before you go and buy the 8 rib setup. Just me though. And how loose is your shit now?

as of right now its tight but if I were to nail it, at about 4500-4700RPM you can hear it slip. It sounds like the power stearing belt locked up, thats how loud it can get. Also, there is a power loss that you can feel until you let go. I should get the wrap kit today or tomarrow, the 8 rib I think will just be extra protection. besides, Im going to need to get all the help I can to keep up with Stever crazy Buick GS!!

Whats your scans say for MAP kpa when your at those RPMs? Is there a dip or a quick drop off? Have you inspected all your pulleys to make sure they are spinning freely?

BAD PANDA!!!

You would be proud of my panda I did scan but i dont think its the same thing your thinking of. What I did was open all those boxes, MAF,Boost, ect. I want to do the log thing but am unsure how to do it.. Any tips will be helpful. Atleast im trying to use my tuner for something besides clearing codes.. Be proud panda, be proud!!!

agreed. I had the same issue with my 2.8 but that was on a Gen V blower. ended up going to a 3.0 and life is good.

good luck with that set up. hope it works out.
