Anyone running them and think they're any good? https://928motorsports.com/parts/8ribpulley.php The tbatt kit addresses slippage on the serpentine side but wasn't sure if slippage is an issue on the input side since my issue was not due to belt slippage in particular. And this kit already has the impeller upgrade, correct? Or is it just upgraded Si bell housing?

I can answer a couple of your questions. I've got bad belt slippage on the jackshaft pulley, sc side and I do have a sur grip pulley to put on it when my sc comes back from 928. My sc pulley is a high traction from vortech and I had no belt slippage on that one. The 928 pulley is really gritty, I can't imagine I'll have any slippage with it.

Topgunz's kit comes with the v3 Si supercharger, it has the Si impeller which is an upgrade from the Sci.

"I've got bad balt slippage"--says the guy making 12 and a half PSI and nearly 600whp?

Downsides I've heard about the sur-grip is belt dust getting on intake filter, and replacing belts more. I think for the time being I'll go with standard until I decide I have bad slippage as well. Will be excited to see your new setup and what you do with the intake.

But if I wasn't getting belt slippage and boost wasn't dropping off completely at 6900rpm, maybe I could have hit 600.

My belt is wearing pretty quickly as is with the belt slippage. We'll see how it holds up with the sur-grip.

Hopefully I'll have some updates on the other things we're working on in the next couple of weeks.

Well you have me convinced that I need that now too. Better to have the car tuned with it on and hopefully not slipping at 6900RPM than decide later on I need it. Your numbers/figures still blow my mind. And you just have the 9lb pulley? Stock topgunz crank pulley and input pulley? My final test for this car would be an extended road trip because to pass the final test it needs to prove itself to be moderately reliable. A trip from Denver-Utah-SoCal and back up (maybe through AZ) would fit the bill and we should cruise GMR someday

No, they go to a larger idler, not smaller. The larger idler takes up the slack.

G3RSTY7 · 07-14-2018, 04:11 PM

It took the force of god with that pulley puller and one large crescent wrench to get that pulley off. No way the shaft isn’t bent and/or pulley is scuffed beyond use. Also hear a bit of a whirl when I spin it that my buddy says he hasn’t heard in his, so no surprise but rebuild coming in addition to new pulley and shaft. Ceramic bearings and seals, wondering if ordering a new oil slinger could be cheap insurance, and wave washer. Hope i don’t miss any damage and blower starts tearing itself apart once i get it back on the road in case i miss something. Redon’s a bad influence ill probably be pushing 14psi on stock block before long too lol. Were at high elevation though so i could be ok but boom once i take a road trip to low elevation. Hope seb has some magic up his sleeve haha

Are you doing the super vortech upgrade or just bearings and seals? Can 928 do a complete rebuild on it or does it have to be sent to vortech for that? Hope I didn't hurt your arm twisting it so hard.

I wonder if Seb can do a low elevation tune and set it as a switchable map?

I’ll ask him about tune maybe request your low elevation if were similar but isnt our impeller already upgraded? Hope mines still good and it doesnt need replacement so hope only bearings/seals and pulleys

The Si impeller is an upgrade from the Sci. The 928 is a billet impeller and according to them it's an upgrade to both the Sci and Si.

I just swapped out my SC-side pulleys for the Vortech high-traction and the larger idler. Wasn't terribly difficult. I fashioned my own spacer out of a 3/4" x 1" x 1" steel spacer from Lowe's. The shaft is 0.785" and the required spacing is 3/8", just FYI. I cut the spacer to 3/8" and dremelled out the inner surface until it fit on snugly with a little effort. Remember, the idler pulley also needs a 3/8" spacer (or washers, since they don't spin)!!!

I bought a 3/8-24 x 2" bolt for the jackshaft and I used the old jackshaft bolt for the new SC pulley.

Also FYI, I had an old 8-rib belt lying around that I used to wrap the SC pulley while loosening the pulley bolt.

I can get pictures of the specifics, if desired.

I already have the spacer from 928, thanks for the info on it needing to be 3/8" and the bolt length, good info. I was going to use washers on the idler pulley.

Are you still on the Stillen?

EVOHUNTER · 07-16-2018, 01:34 PM

Yes i do, its been sitting for 2 years now LOL!

Im having it tuned this week. hopefully my fuel system holds, stock jack and stock serp side, 2.80" on blower with low/mid range impeller.

I like that little tensioner/pulley for the serp side belt, can you sell me that little piece? lol
i bet that baby helps with belt slippage

batboyvaj · 07-16-2018, 09:39 PM

Do you have anyone running this kit with a TI trim? Or a V2 head unit?
