20-25 RWHP w/CAI & tune; exhaust work will add probably another 30-35 RWHP, w/similar torque gains on both sides also.

What engine do you have?

So lets see if im in the ballpark here:
-CAI + Tune = 20 to 25 hp
-Headers + Midpipe + Catback = 25 to 30 hp
-Throttle Body = 10 to 15 hp (it actually states 15 rwhp on americanmuscle)

So in total around upwards of 70 rwhp & 70 ft lbs torque correct?

And any suggestions on what more I can add or is it jjust supercharging & nitrous left?

Thanks so much

Its the 3.7 V6 bro not the 5.0, but i do plan on looking at the 2020-2021 S650 GT's when they release!

That's ricer math - it doesn't work that way. With all of that together you won't get 70rwhp. You can't take each of the modifications and their "claimed increase" and add them all together to get a figure. With all of that, and the most performance gains are always in the tune, you will be lucky to see more than 25-30rwhp gain.

So from a 300 hp stock car with 235-245 to the wheel with 87 octane regular gas with no tune to $4000+ worth of mods and a tune for 25-30 rwhp gain? i think.your math is off lol that sounds way to low of an increase. That's why I'm asking for dyno sheets for proof of what people actually get cause i was told directly from American Muscle via live chat that I would see an increase of 45-50 rwhp bout an hour ago. So what's up with that everybody's giving me different numbers.

No, his math is very close.

-Cold Air Intake = Maybe 5 HP if you're lucky
-93 Race Tune = About 20 HP if you go for a 93 tune from a good tuner
-Catback Exhaust = 5 HP at most
-Long Tube Headers = 10 HP
-Shorty Catted H-Pipe = maaaybe 1 to 3 HP
Throttle Body = 0 HP. Total waste of money

43 HP total and I'm being overly optimistic.

There are several points you have to take into account. First your car's intake is not that bad, the OEM throttle body is fine, the headers would have done more if you had gone catless and the catback exhaust is mostly a sound improvement.

I A-S-S-U-M-E-D you were talking V8, not V6, however, I'd still guess w/all those mods you're looking at about 45-50 RWHP overall. 25-30 seems mighty low, in my estimation.

Parker9090

40-50 sounds more like it and would be a noticible increase in both horsepower, torque, and throttle response. Am I wrong? Im dropping a lot of money into this thing just not supercharging her as I have other plans.

Thanks pal! I just really want to notice the gains after it's all said and done and I re-tune it.

Anybody with experience or dyno sheets is still welcome!

The HP gains from a CAI and tune will vary depending on the type of CAI that's installed, and how good or bad the stock tune was in the first place. A top performing CAI with a good tune will elevate the output to 285-290rwhp. If your stock baseline was 270rwhp, you'll gain 15-20rwhp and if your stock baseline was 260rwhp, you'll gain 25-30rwhp. The difference is the state of the stock tune.
A full LT headers back exhaust will add a further 15-17rwhp and a TB maybe only 2hp, so your car should have about 305rwhp and 320rwtq after the next round of mods.
You could gain a further 15rwhp & 15rwtq by adding charge motion delete plates and underdrive pulleys. You'd need another retune though after installing CMDPs (you can convert your existing CMCVs into delete plates and save $280), but the end result of about 320rwhp & 335rwtq will be a lot of fun with better gas mileage to boot.
