Sounds like a good plan! I dont think porting the heads is a worthwhile idea. Id milk that warranty as long as you can and just cruise! Aero mods and maybe a sportier exhaust? Not sure whats on it now.

Right now I have ported/coated OEM exhaust manifolds, stock primary cats w/DEI heatshields, secondary cat-delete Borla X-pipe, and the optional NPP (dual-mode) mufflers.

Ahh okay yea then you are all set there!

If someone would have told us 10 years ago that wed be driving corvettes in 2016, we'd laugh so hard... lol

I would agree on the exhaust. The ported/coated manifolds showed nice gains on the dyno (+11whp/+8wtq) and flowbench, the primary cats are high-flowing 3" and don't seem all that restrictive, and the Borla X-pipe and NPP axle-back w/mufflers are all dual 2.75" diameter.

A guy I know tested a set of ARH mid-length headers w/HFC's and his gains were barely more than my ported/coated OEM manifolds on the same dyno (21st Century Muscle Cars in Addison, TX). He saw +11whp/+14wtq; so if I were to go that route, I'd spend $1500 and gain +6wtq and no whp.

Regarding your 2nd point...I would have told you that you're crazy :lol:

HA! No. Seems like everyone who gets a C7 turbo kit immediately sells the car as soon as it lays down a glory pull on the dyno. Nobody will give a reason, but my guess is massive issues dealing with all the heat in the snug engine bay.

Rear mount turbos. :D

I have the oil issue with the AFM in my Tahoe, I just get the oil changed every 3000 miles and then I don't have to worry about it. Does kinda suck though, especially when I see no benefit at 14mpg.

Here's an AFM disable module you can plug into your OBDII port: http://www.diablosport.com/shop/sprint-active-fuel-management-module.html

I guess it comes down to if you think the service dept at your dealership would notice/care about the cam. If you think they would notice right away or void your warranty for it then don't do it. Really though the only way they'd ever know for sure is if you lost a motor. So only the person that eventually buys it from you needs to worry :lol:

But you might be able to get by with one of the milder ones without having to go nuts on the heads too with lifters, pushrods, springs, etc, etc


Maybe just send these guys a line and let em use your car to develop a C7 turbo kit :) That should cure the itch for awhile.

I hope those things have super heat resistant starters or come with one hell of a heat shield! :eek:
