[Z06] H/C vs FI
#5
again, the MAX you could ever do with head/cam is 600RWHP, I started with a blower at low boost (5PSI), and am now working on bumping the boost pressure to 12-14.
The blower package IS heavier but you can EASILY compensate for that added weight by more power. Also its much more expensive.

You are going to have to forge those internals, and go lower compression, no way your stock bottom end is going to hold even 10lbs of boost with stock internals. A guy in the C6 section just blew his motor on 9lbs of boost, the bottom ends aren't any stronger on the LS7 vs the LS3. Heads and cam is the way to go unless you start tearing down the engine, the 8k budget will at least be doubled with FI

I priced the new Vortech kit installed and tuned for $7,800. We are estimating near 600RWH with 5+ boost. H/C came in around $7,000. with no warranty and estimate 550RWH.

Having had a couple Supercharged cars and a couple Head/Cam cars, I can tell you that you will be happier with the Supercharger. Your car is going to run around like stock until you get on it and then you'll have 600rwhp.
The H/C car is going to take a certain degree of driveability away. Not much if done right, but the Supercharger will be better. Plus most H/C cars only put out around 550rwhp.
If you go with a Supercharger, I personally would recommend going with ATI.
My Viper has the Paxton and drives around like a stock car. You can't even tell it has the blower at all, till you really get on it.

Listen to this guy. FI is the way to go for sure. My car drives just like stock untill you hit the gas and then it will blow you away. I have the vortech kit, and have no complaints whatsoever. 580rwhp on 5-6 PSI. Everything else is completely stock and running perfect.

Here is another way to look at it.
How long do you plan on keeping the car?
You might want to consider FI, if you plan on selling the car in the near future. It would be easier to take out and sell the car as stock.
If you plan on keeping the car for a long time, and want to spend more money on mods, go H/C route.

For those on the fence as well, I suggest driving a FI car then a HC car to see the huge difference in driveability. As already stated, a FI car will drive just like stock until you step on it further, with one exception. The torque is much greater off the line and makes the car drive like stock but much more powerful and responsive.
Having said that, for the stock C6Z I would probably do HC. For any other LSx car out there, I would go FI, IMO.

One of the other reasons for thinking FI over HC we are at 6500 elevation average and my home is 7600. However that said I am still on the fence and looking for all the info I can find. Running down to the drag track 2 to 3 times a year and cross country track on occasion.
