Getting closer-.700" lift just before coil bind, Trend .135" wall 9.9" pushrods-should RPM nicely. J.Rob
Waiting patiently for the big number.
Does it slip at the crank pulley or can you tell?This build has just about reached its conclusion for me. It has been an uphill battle almost all the way as far as the shiny stuff mounted to the front of it is concerned. Fab discharge tube, remove intake and install all the fittings, move damper back .500" , source the correct length accessory belt since Tq-Storm sent one 4" too long, set carb up for blow through, plumb rising rate fuel system..........On and On and On. Long story short it sure looks and sounds promising but BELT SLIP above 4500 RPM sets in and I am in no position to start re-engineering the whole dang drive system. J.Rob

doesn't look to be much belt wrap at the crank pulley, maybe add another idler driver's side between the crank and s/charger. or swap to a toothed belt and pulleys for zero slip.
i don't get why they don't come with a toothed belt? seems crazy after all these years of 'known' belt slippage with the multi rib ones.Seems like every single centrifugal supercharger build I see has the same damn belt slip problems. I don’t blame you for being done with it.
I agree. But I think most of these kits are considered “entry level” and are purposed as such. They don’t expect people to use them in more than street car type stuff at low to mid boost levels, 5-10 psi. Most of the issues I’ve experienced are about the 10-12psi and 4800rpm range when they just can’t maintain a tight belt any longer. I had a vortec v1 s trim on a 347 sbf in a mustang and it lasted a month before I got tired of chasing belt issues. Centrifugal out…….turbos in.i don't get why they don't come with a toothed belt? seems crazy after all these years of 'known' belt slippage with the multi rib ones.

i guess so but what difference cost wise would it be at the manufacturing stage to build the kits with a toothed belt instead of multi rib? if it was another $200 it'd be worth it surely.I agree.

a lot of other pulleys to swap out otherwise. i'd rather swap all the pulleys and have no belt slip mind.I think the tooth belt thing kinda requires the blower has it’s own belt?
me too, lol.I’d rather have turbos.
Or a crank drive pro charger.I’d rather have turbos.
if you got the room.Or a crank drive pro charger.
Just take the radiator out and put a 5 gal. tank in there.if you got the room.

It's also an option on their other kits.I noticed browsing around on the supercharger store website, the higher-HP Procharger kits they sell do come with a toothed belt instead of a normal ribbed one.
