So heres my question. There are a large number of zs out there spraying over 100 hp of nitrous at the wheels and there are a large number of zs out there running sc and tt kits putting out over 100 + hp to the wheels my question is are those of you who spent the money on the non nitrous kit regreting it? For the last 4 months ive been reading about the many forms of FI I understand that with what i will now refer to as nos not the brand its not always on and available. But all things considered sc/tt applications are 5xs the price. I read more posts of ati owners having problems than anything else so i want to stay away from them. Can anyone please explain to me the advantages of these applications and why u chose them? Thanks James

 

James:
I am running a G35 with the ATI, more than 3000 trouble free miles. I have about 360+rwhp per the dyno and about 320lbft of torque, on 7psi pulley. that is about a 140 rwhp increase. I love the little bugger. That is not to say that the application is without risk. It is full of risk. Though trying hard to avoid problems, they might jump up and get me. But so is any FI that puts that type of pressure on your engine. Turbos and SC units, no matter the brand, are going to have some issues until the interface with the ECU and the understanding of how the engine runs lean at high RPMs is worked out. There is nothing fundamentally wrong with either the engine or the boost units. It is the learning experience with the mating of the two together that is the present challenge, and that is to be expected early on.

Nitrous is VIOLENT. It is a short burst of explosive energy that gives outstanding results, for a limited time period. It puts your engine under very high strain. If it suits your situational needs for power, it is a cheaper way to go for the set up. Filling the bottle is not real cheap, but if you are not into it a lot, perhaps cheaper than the impact of gas mileage reduction of the other two. (turbo is much more efficient than SC in that regard, as it uses waste energy while the SC is parasitically driven by belts off the crank). But when your bottle is empty, you have shot your load and you are over and done with.

TT and SC are there for you to call upon all the time, and thus are a more or less permanently available source of high power. That is what you are paying for with the set ups. When you go, you go and go and go till you win, you lose or run out of gas.

For all three you can also go until you blow up if you did it wrong somehow.

As for the set ups. There are lots of them. You have single screw or Roots/Eaton type blowers (Stillen) which kick in peak power at relatively lower rpms on this motor (like 2500-3000), and you have centrifugal type blowers (ATI/Vortech) that kick in peak power at relatively higher rpms on this motor (like 5500+), and you have twin screw or Lysholm type blowers, which I have not seen any applications to this car for, but they are somewhat in between the other two types, harder and more expensive to manufacture, but have a lot of very positive attributes (no use discussing it here if there are none to buy!). Suffice to say that if there had been a twin screw unit I would have bought it. But, I did not want to wait. There is also a Dreamworks kit and some others coming.

Greddy has the TT now, and there are some others coming too.

This is all great, as the competition should help with research and development, and problem diagnosis and resolution, and thus reliability enhancement and risk reduction, and also affordability for the consumer.

Pesonally....I like all these kits. They make you go like a bat. But keep your expectations in check. This is not a "fire and forget" weapon. You have to watch this all the time or it will break on you. If you cannot afford to break your car...do not play the game.

 

the Stillen is a twin screw avail. with a water to air intercooler.the dreamworks is the single eaton style.

 

Plus NOS will only suit you on a straight and not useable for anything else, and as mentioned once you shoot your load you are done.

NOS might be a good suplement to FI if you have a car that doesn't have the torque the 350Z does at low RPM's.

 

I done to all my cars NOS and then FI and the kick of the NOS is amazing... I have NOS rigth now and the car is a beast... but eventually I will go FI

 

i want to do fi but am having a little problem spending the cash. The nos sound pretty safe and the fi seems to have some fuel pressure issues. if those issues are worked out in some of the up and coming kits then i think i might be a litttle more ready to hand over the cash

 

You CAN use a 50 shot while drifting the tail around corners.
Nitrous is NOT for straight line use only.

 

doesnt matter what you do James your still not going to be beat me

I think the charger when done right is the best bet. Im going with all NA because I want the car to last a long time, cams, etc...are better for my personal style...plus I can hit the spray when I want....

 

p.s.

Your Girls hot!!!!

 

thanks tim so is yours, I think im gonna wait to see what happens and decide next winter when i put the car in storage ill have it done

 

Wow, just the consumate race driver, drifting with NOS around corners, real safe there

 

SPRAY, SPRAY, SPRAY

Reason 1: wont put engine under constant additional stress like turbo or supercharger

Reason 2: 9 out of 10 engine blow-ups with G35's and Z's are supercharger/turbo related (not that nitrous is much safer if not tuned properly)

Reason 3: Easy install (and removal if you need to go to the dealership)

Reason 4: A Whole Lot less $$$


Maybe some reasons why you shouldn't get nitrous:
1. Only can use in 15-second bursts -> so for auto-cross or track racing, it may not be a good idea, but running turbos or superchargers in auto x or on track puts intense strain on motor and can result in overheating and engine failure.

2. Have to fill up the bottle - its appx $30 per bottle. Hope a nitrous station is close to home or work or it will be pain in the ***. This stinks, but you can get a maximizer kit (2 bottles) or a filled up second bottle for spare when you run out.

3. Run out of spray while racing - make sure you have a nitrous pressure guage to know when your spray is getting low.

4. Bottle open and close - if you don't have a remote bottle opener, you'll either need to open the bottle manually everytime you get in the car or jump out at the light and open the bottle when your ready to race (looks stupid and obvious). GET A REMOE BOTTLE OPENER.

5. Safety - nitrous is completely safe until you 1) try to spray too much (do a search on smithtown nissan for a kaboom video) and 2) have a too rich or lean condition. To ensure you don't go kaboom because of too rich or too lean, there are window switches and a/f switches that will cut the nitrous if you reach a certain rpm or run rich/lean.

I am running 150-shot, which is giving me a dyno'ed 137 to the wheels. Peopke are running a 175 and 200 shot, but need upgraded clutches and some other magic to ensure they run right. I got my 150 crank horses with tons of accessories (guages, switches, bottle warmer, remote bottle opener, etc...) for a little over $1000 as opposed to a supercharger/turbo costing from 4 - 8 times that.

 

I like boost period, can't get myself to get hype over NOS though. I like to run around on the street quickly on occasion, but never really long enough to use NOS. Heck, you don't have to put the car to the floor on every occasion to feel like you are running. NOS is just too temporary and short for me to really get into it, if I were a dragger, I would do it in a second though.

To each is own, decide what is best for you. Having alot of HP in daily traffic is just fun to me. The only way you can really do this is by TT or SC. On the street, sometimes I just hit like 2nd gear from the bottom to the redline. With NOS, this would be a real waste of juice. But hitting just one gear with TT or SC would be a blast, this is making me dream, lol.
