Procharger whp expectation?

PaulG,

By all means use what you have (PS4's). This is an expensive game we play.

Just be careful, you'll see what we all mean about the PS4 tires once you get your FI up and running.

I'd wait for the 555r2 to come back as it's better for a dd and can handle rain etc.

How well do the 555R2's handle cornering when coupled with the nitto summer tire up front?
Compared to the PS4s

I finally got the car dyno'd. I ended up using a BAP and DW95 injectors. Numbers are actually a little lower than I expected, thought they would be higher since they are using STD and I had Boostane in the tank. In the ballpark I was figuring though.

622whp on the first pull was the best I saw.

Thanks all for the responses. It is a fully stock HO kit with the P1x head unit. Im not sure what pulley size it comes with, but it will be on Prochargers tune for 93 pump gas. As mention the car is a gen 2 with a 6MT.

I don't really have a goal for the car, but was hoping it would put me in the 550-600hp range.

I have already ordered the kit (from beefcake), so now Im just waiting and have nothing to do but research for the next couple weeks.

I'm late to this conversation, but six months ago I had a Stage 1 Procharger put on my 2015 GT, and it came in exactly at 600 WHP. I have no regrets whatsoever.

I got a 2019 10r80 with the stage 2 tuner kit, upgraded intercooler, helical quiet gears, p1x with a 4.75" pulley and made 640RWHP / 513 torque on 93 pump gas. So that's about in line. I've added LTH's since then but haven't put it on the dyno again to see the change. I'd said it's negligible but the sound makes it feel way faster.

Still running the stock PS4S Michelins, 255/275s and 2nd gear is a no go. 3rd is a 50/50 chance of it hooking but when it does it rips. Once these tires need replacing I'm gonna get a set of rims to accommodate some 305 PS4S's.

I have the 4.75 pulley as well on my 2020 PP1. If you don't mind, who are you tuned by and how much boost at what rpm are you making?
