Bro I wasn't referring to the Corvette(just sold it a month ago 
,cant afford 2 10 second cars the way the gas prices are, one had to go, and that was a no brainer. I was referring to the Viper ACR, the Vette motor(after it blew up) had all forged, lunati, pistons rods, crank, cartek stage 3 heads/came, along with every other bolt-on, very very not stock internals. I was wondering if powerhouse would like a stab at tuning my viper useing a Viper engine control management (VEC2) the closest viper tuner is in st. louis, but I need it done right, I'm gonna have to give them a call.

I haven't upgraded my signature, don't have 1400hp, but over 800, major work?
nope , motor has not been opened, runs like a champ, gets beat, and wants more
, very satisfied, the clutch is getting a little unhappy, but hat will be changed soon. ZR1, like the Supra's(dont like supras but give credit where it is due), and pre- 2000 vipers, are built to handle allot of hp. Its about time GM put stout internals in the Vette, this should have been done in the LS7.

So, I say that major engine work will be required to make it to 1400 hp and withstand 45 lbs of boost on any LS engine, and you refute my statement by saying that you have made it to 800 hp on a viper without any engine upgrades. What does that prove? Your post doesn't make any sense.
800 hp is not 1400 hp dude, and a viper motor is not an LS9...

If they can give the Ford GT's 5.4L 250 (est.) bhp on just bolt ons (full exhaust, intake, pulley, throttle body, tune), why can't the ZR1, with a lil more displacement make the same amount of power or even a lil more on just bolt ons?
There are a couple other options when it comes down to it.
I'm thinking a bigger cam will push out anywhere from 50 to 100 bhp, maybe even more. Then on top of that, you can port the supercharger, which can give up to about 50 bhp.
Now to be optimistic and perhaps somewhat unrealistic, if you want to put out big power on the stock blower.
(Full Bolt Ons) + (Cam) + (Ported Blower) + (Base) = (300) + (100) + (50) + (638) = 1088 HP
In my opinion, this is not enough power, since there are viper guys I know that are putting down well over 1000 just to the wheels.
Now I'm not sure if it'll do the job, but if you spray the car (and are willing to do so), with a 150 dry shot, you should make more power. Generally speaking, spray + blower = some type of exponential increase of power.
So lets say it gets you about 200 to 230 to the crank (since most shots are rated to the wheels) from that.
You end up with 1088 HP + 230 HP = 1318 BHP.
I guess thats assuming the internals of the car will hold up, which I don't see why not, since they are forged, like the Gen 1 and 2 Vipers.

except that for 700 crank HP it probably won't need the pulley.

What will it take to get the Zr1 to 700HP? or 800? At what point do the mods get expensive and at what HP will it be at when it gets there? What kind of HP do you think just a CAI and pully will get it? Any tuner/installers have an educated guess? Just curious. I couldn't dump my z for it though. 427!!!!!!!!!

Example:
FGT rod: 4340 forged steel H beam rods...proven for 800+ rwhp
LS9 rod: Ti rod similar to LS7 rod...unacceptable for 800+ rwhp according to most engine shops that build these LS motors for a living.
Your power estimates for those mods listed are well beyond unrealistic. An additional 450 hp from bolt ons, a cam and a ported blower? Surely, you jest.
As far as the internals holding up, call up any of the sponsors listed and ask them if they would feel comfortable using the stock Ti rods for over 1300 hp at the flywheel and see what they say.
Also, with all the other LS engines running into head gasket issues even with ARP head studs at power levels under what you have listed, what gives you reason to believe that this will not be the case on the LS9?

Yeah I guess it was a bit unrealistic. Rough and very optimistic estimate. Haha.
Just wanted to see what people thought of that. We maybe able to reach around 800rwhp on just bolt ons though.
