Results of Procharger P1X with FBO/Heads/Cam

Saberscar223 · 10-08-2025, 09:54 PM

I just got my car back from the shop with the Procharger installed, it’s been pretty great so far. With about 5.5 psi on the stock 4.13 pulley I made 645whp and 678tq. I plan on getting a 3.9 pulley installed to up the boost a few pounds. Here’s a sound clip of it https://youtube.com/shorts/jZBgU0Rmg...qRUokr0_scsbse

It has helical gears, Stage 2 Intercooler and the big red race valve.

Nice! That is some serious low end torque!!!

Saberscar223 · 10-08-2025, 10:54 PM

Yeah I was very shocked by how much Tq it has I expected much less tq like high 500s at most with a Centrifugal Supercharger

Nice dude. What’s your IATs like?

Looks like they gave you someone else's dyno graph, doesn't make power like any Procharger I've seen.

Edit: there's definitely something wrong here, you're not going to be making 678 wtq at less than 3,000 RPM on a P1X setup pullied for 5.5 PSI.

Falling off hard up top. I would be concerned about that.

I was at pretty high elevation and that's the adjusted numbers maybe that has something to do with it? Also its pullyed for 7 psi but he said my cam and being at elevation I lose some boost.

It does seem like the power curve is much more inline with a PD supercharger rather than a centrifugal its odd because from everything I've seen ~650whp is about right with those mods.

Saberscar223 · 10-09-2025, 12:27 PM

Im getting it tuned again when I get the 3.9 pulley and a catch can so maybe it was just a sheet mix up

See if they can send you the correct one so you'll have results from the pulley swap.

my Whipple keeps making power with a stock cam clear out to 6500rpm.

It's laying over up top because something isn't happy.

Someone else's car with a PD blower wasn't happy.

Yeah, I just looked back at the graph again from my computer and seen you revised post. I agree with that. P1x would isn't making that much torque down low...especially with the pulley combination. 6psi peak is likely only 1-2psi down around 2500rpm.
