So I just picked up a really clean 2001 Corvette Z06 with HCI and milled and BTR ported heads and nitrous cam and plate.
It's set up with a 200 wet shot using an nitrous outlet plate system and an NX fuel cell. It's wired to cut timing 7 degrees when the nitrous is armed. The car is really clean and the system installation seems really well done.
Setup makes 477whp off nitrous and 700+whp and 800+ft lbs on nitrous. Was set up and tuned by Phil at bluecat tuning.
I'm not super familiar with nitrous setups, I know how it all works but I'm concerned with the stock bottom end at these power levels. I know boosted engines and I know with good detonation control that gen 3 rods are definitely being pushed hard at 7-800hp. The guy I bought it from did a lot of roll racing with it and I wouldn't put it past him to use a really aggressive setup.
At 11+CR and stock bottom end is 200 shot really pushing things? Or do you guys think this combo is safe?
Anyone know of any LS nitrous experts in Minnesota or Wisconsin who can take a look at my system and make sure it's done correctly? Or can help me pull the system down to a 100-150 shot if 200 is pushing it?

I really don't want to wreck a perfectly good 24k mile LS6. My long term plans with this car involve pulling out the LS6 and experimenting with a SBE 6.0 or 5.3 with a big procharger. So I want this setup to be perfectly reliable.
I mostly bought the car because of it's 2013 C6Z drivetrain and cradle swap, 15" rear conversion, and coilovers.
How do I go about getting it down to 150?
It's a nitrous outlet plate kit. And it's a wet shot, but I have no idea what jets to change to for the fuel or the nitrous.
It currently comes on at 4k rpm. I've got to look in to my controller because there's already features in it the seller didn't tell me about. Like that it only activates in an RPM window not just at wot.
I'm going to forge the motor this winter. And then I assume I can safely run a 250 shot?

Did you try contacting Nitrous Outlet? Forged motor 250+ is fine.
Yeah i've noticed most nitrous companies will start you out a bit conservative and rich. You might need to play with the fuel jets a little to get the optimal AFR
You can run a bigger hit but it should be with a progressive controller. Look at how much power people make with boost on SBE. They are ramping in the power, "boost curve" compared to smacking the giggle button and adding 300hp in less than .2 seconds.
The other big part of that is what fuel you are running.
That particular engine combo I would think the first failure point is going to be the ring end gap. Not pistons, rods and definitely not crankshaft.
Since you are running a NX fuel cell I hope you are running good fuel in it.
Also timing...oh timing. That's what blows **** up.
Actually it's normally pump gas and too much timing...or running way to rich...then too much timing...but I digress.

HELP: 200 shot on SBE LS6 with milled heads
