Jan.2020 I bought a base C6, LS2 with 6L80 auto trans. It came with an EForce supercharger. Had I known more about these cars I wouldv have held out for a C7 Z06.
Compared to nowdays I got a good deal.
Mods since then are Kooks headers to ATAK mufflers, big fuel system, small cam that suites the stock stall, flex fuel, 3 more lbs. boost and tuned to 605whp on the shop E98.
Its a perty fast, very smooth & reliable cruiser.
The shop that does the work isnt real keen adding more power. I suggested ported AFR heads. They said for parts, install and tune would be 4000$ and not worth the 40hp and with the 10.9 compression in the LS2 with the Eforce they dont want to destroy the engine.
I dont want to put a new engine in 'this car.
Is this as far I should go with this car?
Thank you
Just keep in mind that the LS3 has lower compression that the LS2, and why you can throw more boost at the stock LS3 motor.
The LS9 has even lower compression, is built a little stronger, and why you can throw 26lbs at the stock LS9 and still be on the safe side.
Note, remember when they came out with the LS9, the LS3 swapped to the same block as the LS9. So you have LS2 blocks, slightly stronger (pre-ls9) LS3 blocks, then the stronger ls3 and ls9 block since when the LS9 came out, they used the same block for the LS3 as well.
So on LS2 block, be happy with around 700hp on that stock block with suporting long tube headers, suporting cam, and meth system to prevent detonation cooling system problems on stock pump fuel with the TVS-2300. If you want to go more than this, then stock crank is good for 1K, but will need to replace the pistons and rods with some thing that can handle the increased pressure/HP instead. Also, don't forget to increase the piston ring gaps, so they don't go to Zero gap from the heat to just rip the tops of pistons off, since Zero gap means that they are binding on the cylinder walls.
With E you get better octane and a cooling effect to your intake air temps. With a blower specific camshaft, you should be fine with the 3.25" pulley. I've had two TVS2300's on LS3 powered Vettes. One with a 3.3" pulley and one with a 3.2" pulley. They made either side of 650 rwhp on pump 93 octane. The 3.25" pulley should give you another 45ish rwhp and run your boost up about 2.5#'s
What are your goals? Do you race your Corvette at the track? Why do you feel you need more power? Having 605 RWHP on tap is a lot of power for most people. More than enough power to take down a stock Z06 or Zr1.
I agree with the others that you could push it a little further, but I am not sure if you bought a Z06 and wanted to push it to over 600 rwhp it would be any better or more reliable than your current setup.

It can be seen and heard at ig.

Leave it. There's nothing wrong with it. The shop is warning you not to go further and if you do, there's a good chance you will lose this "very smooth & reliable cruiser." You've just gotten used to the power and/or bored with the car as it sits and you're looking for a project. My suggestion, maybe look into some cosmetic mods or an upgraded sound system to reinvigorate your passion with the car.
Everyone who knows about this type of thing says the same thing. Its good as is.
I just want to be as ready when someone rolls up wanting to try granpa in the stock appearing granpa Vette. Cant even hear the blower.

Thanks guys for your opinions.

Even better. I love sleepers. Well, as much a Corvette can be considered a sleeper. Being older is another plus. They wont be expecting what's about to happen to them.
Another vote for leave it. You have the perfect amount of power. There will ALWAYS be someone that's faster. You have the perfect reliable sleeper. If you do anything put a 3200-3600 stall.
I would say that the shop that does your work is giving you some wise advice, short of replacing the engine or making the engine a time bomb, just enjoy what you have

I didn't realize it was an auto. Higher stalled converter and tranny cooler are absolutely the way to go. Keeps you in the powerband through WOT.
Most people see at
least a half a second improvement, some a full second at the 1/4 track if they have the tire because traction will be the challenge...especially at that power level.
What else can I do to it?
