base procharger boost question

I have a base procharger P-1sc-1 with base 4.0 pulley, do people see 7 PSI as procharger states on a stock engine?

Currently, I have the above kit with ported heads and headers, stock exhaust, ported MSD, 103 MM TB, assuming I don't rev it any higher would 6 PSI be expected?

I'm just getting a baseline before I go boost crazy...

Can’t speak for the P-1SC personally, but I’m at 10lbs with a P-1X with the 4” pulley so I’d say it’s very safe to say you should see at least 7lbs.

My P1SC shows 8-9 psi on my digital auto meter gauge depending on ambient temps.

I think you might loose a little PSI because of the headers.

Bone stock with only the ProCharger and the 4.0 pulley I was getting about 7.5 at redline.

That was 2 weeks ago on the dyno with the headers and 4” pulley.

Without the headers I would occasionally see 9.5# at the track. The Autometer has a peak memory and warning light. So it helps since I can’t watch it while racing. Lol

I would be interested, due to my age in this adult toy, does it fit in either of the two common pods? Please provide the part number of toy....

This is the one I got. I don’t ever plan on running “high” boost numbers, so 15psi is good enough for me.

But if fits in the vent pod without and issue.
