OK guys, I am going to try to explain this as well as possible. OK to start things off. I have a 2001 Z06. Its got a built motor, heads/cam and a vortec YSi @ 16lbs. I had the car dynod a few months ago, but the belt was slipping pretty bad(only producing 12-13lbs). Car put down 683 rwhp. I would assume the car is just over 700 rwhp now b/c I replaced the belt and its right at 16lbs again. Thats not really important but figured I'd let you guys know everything.

I was told by the tuner that the computer is tuned to pull timing when the car reaches over (I think) 200* F. So basically right now, the car feels strong as hell until I shift to 4th gear. You can tell its not all there in 4th. So I am on the fence about what I want to do for cooling!! Also I want more power too!! Obviously I have 2 options.

1. Alky Control Meth Kit
2. Nitrous Kit

What is the more "safe" route. I know at this power level nothing is "safe" but I want the safest route.. I am leaning towards nitrous, but then I run into the fact of wether I should go with a wet kit or dry kit. So if you think I should also go nitrous, then which kit should I use? Heres what I've come up with.

Dry Kit: Since I dont really have the money for HP tuners or any other software, I can only have 1 tune. So with that said, the car will have to be tuned for nitrous at all time if I go dry. The car will run rich when off the spray right? I know it depends on the size shot, but I atleast want to spray a 50-75 shot. I feel this would be the easiest/cheapest route b/c the nozzle can be plumbed right into the S/C tube before the MAFS that way the IAT's can be recorded more accuratly.

Now on the other hand, if I go with a

Wet Kit: The car can be tuned with only 1 tune, but I will need to have a IAT sensor after the nitrous Nozzle(in this case a nitrous ring). So some how, I'd have to plumb a IAT sensor into the intake right? I wouldnt mind doing this as long as it doesnt cost too much money, and as long as the work is decently easy. In this case I'd probably spray anywhere from a 75-100 shot

So now if I decide to go meth, not just for cooling but performance. I can up the timing but theres no safety precaution at all. I wouldnt have a chance to take my foot off the throttle if the meth pump stopped.

What do you guys think??? Let me know your opinions on this. I might have left some stuff out but I think this should be enough to let you guys know what I am looking at!!

THANKS in advance...

I would use methanol vs. N2O. The tune can be set to fail-safe fuel and timing maps in the event of non-delivery of methanol.

Also, have you considered improving your intercooler set-up? More surface area (frontal area and / or core thickness), more exposure to air flow (fins and core exposed / not onbstructed), high speed electric fans on the intercooler(s)?

 

meth over nitrous for your needs

 

 

OK.. With methanol, shouldnt I go speed density? Also, how do you tune for methanol fail?

 

I have a pretty big intercooler now that get direct air from in front of the car!!

 

200 degrees is high. With A&A's ram air intercooler and 18psi boost, I hit 172 degrees at the top of 4th in a 1/4 mi run without meth. With meth, I can keep the temps barely above ambient. I am running a 2-bar tune, but you don't have to change to it. All you have to do is put an IAT sensor from a 97 Vette behind the methanol stream and use the IAT vs. Spark table to remove timing if you go into an area that you would only go if you lost the meth. If you have HPtuners and need help with it, PM me and I will help you get it right.
