can anyone give me feed back on the two, which is preferred?

 

Obviously the S/C if properly installed has less issues. You need to be full throttle to take advantage of N2O. You cant let off the gas to regain traction. That said an S/C isnt an off on switch and it doesnt have to be refilled fro 45 bucks every 10 races.

You will need drag radials to get either to the ground and a S/C installed is 3 times the cost of a fully functining reasonably safe nitrous system.

Both are not without serious dangers. If the fuel solenoid doesnt fire you will blow up and if you go lean under boost with a failed anything in the fuel system the same deal. Expect the N2O to be more of a shock due to its unreal TQ.

If you have the money a S/C is the best route these days. 7K with stock part throttle drivability and its removeable in the end to sell the car. Not likely to have nitrous backfires too.

 

I had both on my C5 (at different times). The Nitrous served it's purpose which was to get me into the 11's, but it was a real PITA otherwise. Heating the bottle, filling the bottle, opening the bottle. When the bottle was full and warm it hit hard but once it lost pressure it wouldn't. Filling the bottle was a chore. Even in a big city like Houston there are not that many places that fill bottles. It was a wet kit so you need to retard the timing all the time on the tune to keep from knocking when spraying. The bottle did fit nicely in the rear compartment in the C5 but the C6 doesn't have that.

I ripped the kit out when I got a good deal on an A&A ATI P1 kit. The Supercharger was WAY better! Always on, still drove like stock. Just awesome.

When I bought my C6 from a forum member in OK it had a nice dual bottle plate nitrous system installed already. It was one of the first things I removed because I knew I didn't even want to mess with it.

Just my opinions.

 

IMO if you want to go fast for less N20 if you want the power heat and octane all the time SC or TT, they all have there negatives.

Look through the list with a few mods CAI HEADERS SPRAY 11.1 and traps 123-125 at Altitude 2200+ feet

The SC cars have cams / H/C / 427's to run 11/10's

 

EVERY car I ever own will have nitrous on it...there is nothing better for going fast and making insane power when you want it (at the track) in such a cost effective way.

My vette will have one of my extra dry kits on it by the end of this summer.

 

First of all you can let off the gas anytime you want to regain control.

The cost of a supercharger installed is more like 5 times the cost of a safe nitrous kit installed (unless you go for all of the unnecessary bells and whistles)

Nitrous is VERY safe if you set it up properly. Do a dry kit and there is no fuel to puddle and backfire...you rely on your injectors and fuel pressure which should be up to snuff anyway.

 

My dry kit is working flawlessly though I must admit extremely hard on the drivetrain if spraying from a dig. I can run low 11's all day trapping 125+mph.

I rarely get on the car unless I am out having fun or at the track.

I will admit if I had the cash for a Novi 1500 it would be on my car right now.

 

Nitrous is tons of fun and can be very safe as long as set up and tuned properly. The INSTANT torque is a kick in the **** unlike any other, but it does have downfalls. Refilling bottles sucks. Having to find some way to hide the bottles (if having them in plain sight bothers you) sucks. That it is either ON or OFF, but no in-between, sucks. Good sides are that systems are cheap, you pick up a lot of speed, you get that awesome kick, easy to tune, and the purge looks menacing. Superchargers are awesome but very expensive! Good thing is that for the m ost part, once its on and tuned, you dont have to mess with it again, just fun all the time. Only downside I can MAYBE see to forced induction, besides price, is possible heat issues if you ever plan to road race the car.

 

Spray it, So much eaiser.

 

Just for clarification~ That 10-second car we ran is wayyyy inaccurately described above in how it was configured. We have no idea how it got that far out of whack form how we originally described it.

This is the correct configuration:
DTE 10.89@129.93 (APS Twin Turbo/3.42/DTE Calibration/Catbk/HF cats with stock pipes/T.C./DR's-1.77)

Hope that helps.

 

My last ZO6 had NOS. Its simple...

What can you afford?

 

I have nitrous and did on my last car too. I have a dry kit. You cannot modulate a gas pedal with it and that is what I was reffering to. Progressive controlers are also predetermined increases in power; you cant ride that line on a launch to keep traction. Yes you can come out of the shot and regain control but once you hit it again it is off or on. It isnt the be-all-end-all. I will get a S/C as soon as I feel confident enough to tune one. You can produce more power with a supercharger than the stock bottom end can handle....same as nitrous. I agree they can be made to be very safe as mine is but if you are saying N2O is as safe as a S/C, I disagree. S/C's also have unlimited runs between refills. 10 refills = 450 bucks here in NY.

I like both and am happy I have N2O. The great thing about modding is that you can do what you want. Opinions vary. The fastest C6 I am aware of isnt N2O, its a TT and a S/C on the 2 cars Cartek put in the 9's. Saying its the faster choice isnt accurate.

 

Putting the list of today's fastest C6's up is a terribly poor repesentation IMO.
The C6's have not really been pushed by most of their owners anyway near their max per build. To get a proper representation you should look at the C5 guys since it is basically the same car and they have been pushed much farther than the C6 crowd has to date.
We recently took the C5 stock LS1 engine record with a 9.82 at 138.9 with our SC kit and blower cam. We have also ran 10.3 with just a stock LS1 and SC and that's with a lessor engine to start with and a heavier car.
I'm not saying nitrous is good or bad, that's all opinion and everyone will have one, just that the list does not represent properly at this time. Willisfast has our SC kit and now is making an additional 80+rwhp, but decided to stay away from the track, I'm sure many others are in the same boat.

Since this is an opinion thread, I'll give mine. NOS is a pain in the butt! TT or SC for this guy. NOS has to be constantly monitored for pressure, bottles have to be filled all the time at a good price to boot. By the time you add all the safty extra's you are more than half way to an SC and the NOS expense never ends. Let alone in the winter months getting bottle pressures up fast and so on. No thanks, all I want to do is drive and have the power there all the time.

As far as longevity goes, either can last a long time when set up correctly.

 

I agree that the performance is related but I see head cam packages with little change not performing well...as well I should say.

I think the C5's hook better and transfer weight better. Mod for mod the same tuner packages are making more power on the C6 but not showing better track performance.

Doug what is the weight difference between a C5 frc/Z06 and a C6 base/z51? Is the FRC lighter?

Phil97svt ran a 10.77 all motor and 10.60 before his solid roller motor days started. That was a C5 coupe.

I also like the way the front of the C5 looks compared to the new ones.

 

Depends on whether you want to own your horsepower or rent it.

 

My 2000 FRC weighed 3075 lbs w/ magnesium wheels, fuel on reserve.

My 2008 C6 = about 3217, which is about 30lbs heavier than 2005 - 2007.

 

Supercharge it!!!

Power on command!

If you have the money and want to ALWAYS have the horsepower then supercharge it...that's the answer.

If you want an occasional HP monster for a fraction of the cost the go nitrous.

 

I was thinking coupe to coupe that the C5 was heavier, but I could be wrong, I thought the C6 was 100lbs lighter? I'll have to look that up.

From what I see at our Corvette challenges, the C5 guys are more willing to side step the clutch at 6k rpm to get those great times, while the C6 guys are a little more reserved. I think the times will start dropping when the C6's get a little older and people are more willing to abuse them at the track more.
