How much power left on the table...? Just bought a 2000 Camaro off a member of this forum. It has a 383 in it. As well a GMR twin turbo kit, built M6, and a 12 bolt. :-)
The car was "safely" tuned with 91 octane (Southern California). Exhaust is 3" all the way. Car was tuned at 600-700ft elevation.
The car made 600whp or so at roughly 10.5 psi.
Now my question is: If I were to add a 4" cutout before the 3" Y pipe, retune with 93 octane (by NYC, Jersey side. So just about sea level)... what kind of power could that be? It's gotta be pretty significant for a pump gas setup, no?
I am NOT complaining about a very drivable 600whp twin turbo setup. Just wondering how much more "safe power" I could get out of the car? Not into C16, meth, any of that. I'm a pump gas kind of guy.
The turbo and throttle response should also improve, no? Eliminate some more lag?
EDIT: How about going from an 85mm intake and throttle body from BBK (port matched intake) to a ported 102mm FAST intake and throttle body?

You'll pick up a good bit with an open cutout after a short downpipe. Numbers all depend on the current exhaust setup. It will spool a lot faster then run through a full exhaust which will be very noticeable. As for 93 over 91 i dont see you gaining much there and personally id probably just leave it the way it is timing wise and run 93 for safety. It will need to be retuned for the cutout though because you will probably pick up a little boost with it open.

Really...? Hmm... I thought that Cali had "crappy" gas? That's why I was hoping to maybe add a pound of boost, add some timing, etc... You might be right though. Keeping it safer does sound nice. :-)
The setup was built to have a 4" exhaust from where the down pipes meet all the way through the back. It's 3" and through a magnaflow. I would think it's pretty restrictive being 25% smaller than suggested.

octane= power potential
To not run methanol injection is leaving a ton on the table.
Try 1 tankful of e85 (106 octane) with proper tune/fueling mods and you will never go back to 91 octane ever again.

Well, no E85 readily available. But I have 93. I wouldn't use 91!
Meth isn't "completely" off the table. But I've heard of those systems failing and then blowing up engines (boost and no meth I mean).

Thanks... And I know that. But one thing at a time! Hahahaa. If like to know how much I'm leaving on the table on straight pump gas. I thought 2 points of octane, the elevation change, and the 4" exhaust cutout would prove to be quite a performance gain. Just seeing if anyone else agrees
your biggest gain is going to come from the exhaust cutout. does it have an electronic boost controller? Im gonig for 1000rwhp on pump gas+meth with my TT build, so the fuel is fine.

dont be afraid to throw some timing at it either with the meth kit. on my procharger set up. i ran 93, no meth, stock bottom end. it made 571 rwhp @ 850ft elevation, 6 psi, and 18* of timing. i beat on it for a year with no problems.
I still have the car. I sold the procharger and purchased a couple of turbos. Im in the middle, well, beginning stages of a twin turbo build on an AES 390. For a daily i have an 04 RT neon. Its the real race car lol. And i agree with djfury also, 8:1 is really low compression. You need to cram some air in that thing. My 390 will be sitting at 9.4:1
