The 84s are making crazy power on other platforms, I'm finalizing my list of things to have settled first before I jump so I'm probably early Winter 2026 now on an 84, probably 4" pulley since I want around 800tq (engine) on the stock block w 4 bolt.

Order it with the 3.1 Pulley, I am using a stock block filled with Billet Caps and I'm gonna let her Sing! I'm in the plumbing phase on my Build so I should have it fired up end of this month (March 2026).

Cool hit us back when you get it tuned and ripping.

The 3.1 pulley would be like 14+ psi and I'm already 610tq and 11.7 compression so that sounds like a stock block buster for sure, I'd drive around with a broom in the trunk. LOL

I'm just looking to get near 800tq so probably 6-8psi will do that on an 84mm for me. You guys get to push the limit and let us know what you think. The main issue is the compressor bracket install and belt alignment so you don't shred/ throw belts. Green belt or black belt etc.

Nacs Fab, any updates?

I am getting ready to fire mine up hopefully by the weekend. I upgraded a ton of stuff on the car during the engine install so, it takes time getting everything dialed in. Ill definitely be putting it on a chassis dyno this spring and ill post numbers for you and once it fires, ill post up video.

Anyone on Facebook, check out the latest Video by Kauffmann Racing Equipment. 535 with Hi Ports and 84mm Torqstorm & 3.5 pulley made 964HP/885 TQ on 8psi! I knew these Torqstorms were capable of power!

I have the same inquiries, I friended the Guy who is having the engine done. He had Kauffmann pick both static compression and camshaft, so Ill pass along specs.

The head cfm and intake will give us an idea of what the 3.5 pulley will push that SC 84mm psi level too. If he's as cast High Ports and unported Victor then we got a solid idea but if he's 360cfm at .600 with a ported Northwind etc then most likely that 3.5 pulley is much higher psi for us as cast HP guys which is around 320cfm @ .600 and T2 intake.
