Just went SS4 and Forged. What to expect?

CamaroATL · 07-09-2019, 12:08 PM

I have a 2016 A8 SS. Headers, pray ported TB, pray ported IM, e85, CAI. I just ordered a GPI SS4 custom cam, am getting my stock heads ported, and ordered GPI's drop-in piston/rod set. What should I expect hp-wise? I also have a nitrous setup for 100 shot... just trying to set some expectations for the finished product. Anybody with a similar setup on or off nitrous, would love to hear your feedback.

You'll probably be around 550 to 570 before the nitrous shot. What manifold and throttle body do you have from Pray?

I have the stock ported manifold and stock ported throttle body.

Your going to be leaving some power on the table then especially with that big of a cam wanting to breathe. Most cam cars are running the 95mm/msd combo to help with all the extra airflow coming in.

I'm a big fan of 1 and 7/8 headers but at your level 2" headers would add a good chunk of HP and even midrange torque...

I suppose i'll upgrade to 2" at some point along with an MSD manifold and bigger throttle body but for now, just going to go w/ what I have
