LS2 402 Blower Motor With PSC-1
Like to find if anyone is running a LS2 402 Blower motor with PSC-1. If so what are your dyno numbers and are you still using 6 rib system. My system is from A& A so I have his wrap around bracket. Can't affors a D1 and 8 rib systm yet so I'm going to use my PSC-1 and Andy's bracket on my new LS2 forged 402 (LQ9 heads) at 10-11 lbs which will probably be reduced to 6-8 with new engine due to less restriction. I will be running a 3.65 pulley. I'm hoping to pull about 630-650 RWHP with about 580-600 RWT. Stock LS1 (with alky injection) today with same set up is getting me 520 RWHP with 488 RWT.

It's definitely not the most efficient set-up, but I am running the standard ATI kit (with the smaller twin intercoolers) on my new 402 LS2 motor. The head unit is a lowly P1SC. My dyno numbers are 602 rwhp and 568 rwt (through an A4). There's more available if I were to switch to a single FMIC and upgrade to a D1SC, but I am not sure I want to spend the money at this point. Maybe it will be a winter project...but I am saving up for a C6.
Best of luck!

I have a P1 on a 427 and make about 7-9 PSI that drops off up top. Through an A4 3500stall i make about 660rwhp this is from a 346 p1 same pulley making 525rwhp. Oh yah this is a 6 rib A&A bracket. I agree not very effiecent, the D1 is a better choice.

You should be able to get some very good numbers from this setup. I have a lowly 346 forged, and the given up to the scrap heap A&A DS1C with a 3.85 pulley and I see 12-14 lbs and with ECS Alky I was able to pull a little ole 742 rwhp/655 rwtq and I keep being told to go TT's as they are the rage (but when I built my car last year even the new A&A Vortex/ECS Paxton kits were not even on the market no less a affordable Sick HP TT setup), oh I bought my blower used. You can get good numbers out of the setup if tuned properly
Keep your eye open for a DS1C/F1R head unit as with your forged setup you have a monster of potential on your hands, just think what my DS1C would pull on your 402

Thanks for the input guys.....PSC-1 is going on first with 3.65 pulley then maybe next year upgrade to D1 with 8 rib system.....Hope to get arounf 630 RWHP and 580+ RWT with PSC-1 at about 8-9 psi.....

Definitely doable. Mine's at 545/480 with an ECS P1-SC setup on a LS1 with stock internals. It could be doing a lot more, but that's as far as I'm willing to push the internals.
