Thanks! Couple more questions...

I wonder if this would be a bit much with a 2.95 pulley? The pulley is exactly 8 inches 10 rib set up.

Does anyone know what the part number for the belt would be for this pulley setup?

Also, the balancer did not come with the pin kit but with my cam kit i got a stock balancer bolt. Can I use this bolt with the ATI balaner or do they have their own bolt I did not really see much when I googled this.

This is on a 13 1LE so 3.91 gears. My fuel setup is a DSX auxiliary pump, unlocked factory pump via HP tuners, ID1050x injectors, and a DSX flex fuel kit. My alcohol content is typically at 72-74%. I have plenty of fuel and never drop pressure. I monitor via a wide band in car and a fuel pressure gauge (both AEM). I’m tuned by Matt Sorian.

This is super close to the same setup I am about to run! how does it hook? I am assuming not very good lol. Are you still running stock axels?

I know on the vortech site they have an impeller speed calculator that would be able to give you an idea of how hard it would be pushing the blower.

As far as the belt size I am not sure on that one but hopefully someone else will be able to chime in. [I'm waiting for my rotating assembly to come back from the machine shop and then back to the shop my cars at where we are going to figure out what we are going to do pulley wise (Just upgraded from the Novi)]

I would 100% get the pin kit for the balancer. Even if you were using the stock crank you should pin it. Believe me when I tell you it is worth spending the money on. [Don't even want to get started on how I know. Lol. And I actually purchased the pin kit. Just do yourself the favor.]

As for the balancer bolt you can use the one with the cam kit (I personally went with the ARP bolt just for the added piece of mind and the bonus that it can be used more than once) but either one you choose you would still have to pin the balancer to the crank.

I trapped 145mph with a 7.5” crank 3.15” blower pulley on a ysi-b. That is somewhere around 850-900hp according to online calculators. That is spinning the blower ~57k rpm shifting at 7k. With a 8” crank 2.95” blower you would be spinning it ~65k.

I’m running 315 nittos on stock 20” 1LE wheels. It’ll break loose at 60 on the freeway lol. It needs some ET r’s on 15’s or 17’s for sure. Fun car though
