Using NOS

[smallv6]

I have always been against using NOS on any car, perhaps I have always felt your cheating a bit.
Well last weekend at the track I lined up against a built Z-28, I thought, no problem I can get this guy. I blasted a 12.4 with a crappy 60' time (cant keep those DR's Planted!)
Just as I cross the 1/4 mile mark this dude is right next to me
He ran a 12.5, I thought man that is one fast car!!
After I pulled back into the parking lot after the run, the dude driving the Z-28 comes up and say's Nice Race!!
He was very cool about it and was just floored that he lost to a Turbo 6
Come to find out he is running a 100HP shot of NOS, Now it makes sence why he was so quick.
Later that night as I was enjoying some nacho's, the same guy hit's a 11.9 on street tires
I think that if I am going to mod my car more I am going with NOS.
I cant see spending $1000's of dollars to get to the mid/low 11's
when for about $600.00 I could just get the bottle.
Sure if I ran race gas at $8.00 a gallon and ran with slicks (Which would put me out of the street car class)
I could compete with the NOS guy's no sweat.
But it seems to me with NOS you get the most for your money.
Or am I wrong in assuming this?
If I do decide to get NOS which kit's are available for our cars and how do they hook up?
Thanks for your time

Well if your gona run that youd be foolish to run steet gas , why not do a double fuel system like myself and turn up the boost ? Anyway Nos make a gn specific kit and NX makes a universal kit . If your cars stock upgarde your fuel system and get a low timming chip or your gonna go boom . A few guys on this board have good experiances with the juice , maybe they will chime in . Bottlefeed is on guy if i rember right , try a search on the subject .

If your running 12.4s youve got to have some mods there and if that at street boost if you run like 25psi i cant see you not going 11s

Thanks for the reply,
I am thinking of using the NOS in conjunction with my SMC alky kit.
I have done some searching on here and it seems some people are doing both alky and NOS.
I have variable timing with the T+ and extender chip, and I have read that the nos will raise boost about 3#'s so I will turn it down 3#'s to even things out.
Maybe bottlefed will chime in, he seemed to have good luck with it.

I have a best time of 12.2 @ 109mph. on a TE-44 and 26lbs. of boost and 25/23 timing. 100 octane xylene mix.
The problem is I can never seem to get good traction or hold any real boost at the line.
So I was thinking of soft launching and kicking in the NOS at the 60' mark.

Why not use some of that $600 on tires(et streets) and get a dedent hook? I can't see why you'd be having spool up problems with a 44 a 3in dp and your converter. Or a progressive boost controller to limit boost in 1st gear.

 

[smallv6]

I have Nitto drag radials 275/60/15's
Are the ET streets better?
I do have to address my braking system to hold more boost at the line, it just pushes through the brakes at 3lbs. and up.
Still with my set-up I will only see 11.9 to low 12's without
bigger turbo, bigger stall, better flowing heads. Now I am into some serious money, It just seems NOS is the cheaper route.

 

[trading t/a]

I was debating whether to use nitrous on my car(in the rebuild process currently). After looking into it an seeing many people running good times without it I'm against it now. Ever think about switching wheel cylinders or a trans brake. In the long run a mild tranny rebuild is a lot less costly than a short block. Now you're talking about cash if that happens you'll say to yourself why not port the heads and I may as well go with a little bigger cam. It never ends.

I am never one to talk anyone out of using something on their car, but I think in dollars not sense. I hate to throw money away on things I could've prevented. The reason I got into these cars was to not spend a lot of cash to have a good performer, if I blow it up on some mishap(could be anything from tune to fuel pump probs to bad switch) there goes the theory on these cars. Spend money where it's needed. I'd look into doing the brake job first doesn't cost much and may pay the dividend you need.

By the way I have nittos on my car and my turbo was so big it didn't come on until the 330' mark but it still blew the tires off. A biasply tire will always work better with the low end grunt these engines have you'll need the help in traction anyway.

I used the bottle on my car for about a year. Works great!! I ran an 11.12 at 124 mph with a 75 shot from Nitrous Express. I still had factory unported heads (Upgraded valve springs), TA 62 turbo, Stretch IC, 50 lb inj, 307 fuel pump. Low timing chip is the key. 18-20 degrees of timing with nitrous.

How much boost were you running and what fuel in the tank? Is that a wet or dry kit?

 

[BUICKTR]

It was a Wet system. You could only run a wet system with the Turbo Buick unless you have a FAST system then you could run either Dry or Wet. Without nitrous my boost was set at 22 lbs and when I hit the 75 shot it shot up to 26 lbs. I used C16 fuel just as a precaution.

SOUNDS GOOD TO ME

Small V6 i would say go for it I have had tons of good luck with my systems...My first stage is the most common one people use and its the 75 shot....And i have ran alot of bottle throught this EXTREMELY STOCK motor....I most definetly recomend using the good stuff when it comes to fuel .... But hey as much as we spend on our cars why would we put the cheap stuff in them anyways Just as a heads up we Burn all of our own chips for our thumbwheels for all the different timing settings ....if you want we have all my BIN files on hand. You just need to get ahold of WILKINSHC he is the mad scientist with the lap top in our group let me know if i can help with anything elseSPRAY ON BROTHER!!!!!

 

[Roc87]

Nitrous NOS kit from Holly Part #05301 (Even comes with a chrome up-pipe) I've heard that the jets that come with the kit are wrong though.....

 

[turbov6joe]

I've been playing with a little 60HP shot and have had really good results to date. My TTA runs consistantly at 119 MPH with alky and pump...boost set at 25 psi. On the 60 shot it runs 123 MPH with a base boost of 17>>>increasing to 24 with the converter locked. I used 114 octane initially but have run some 112 with equally as good results. I have the timing set to 21º in 1st and 2nd... then have it scaling back to 19.5º in 3rd.

Are any of you NOS guys running exteranal waste gates? Or are you guys running Terry houston type pipes? Dont you set boost on a Terry houston style pipe by limiting how far the puck can open? Reason I'm asking is because I'm getting ready to put NOS on my car and I run dual delta gates. I'm wondering if my boost level will jump as much as you guys are seeing because I'm running alot of waste gate and I'm not limiting how far they can open. Do you guys think ill see the boost level jump with the NOS?

TIA: Jason

also how big of a difference does the NOS make in spool up time? I run a 63 with a PTE 63 housing and even though I run a art carr 9" she is kind of a pig spooling up from a dead stop. BTW... Spool up and launch is the main reason I'm putting NOS on it.

 

[turbov6joe]

Postal,
I don't think it so much as how much or how many WG's your running than it is what kind of IC your using and how efficient or inefficient it is. For instance, on my old car (GN) with a MJ 17 row IC and just a 60 shot, I would see as much as 3-4 psi increase across the board. Now when I switched to a PT&E FMIC, I would only pick up ~1-2 psi...that's it. All these passes were made with a THDP (internal WG). On my TTA with the OE IC and a big neck I see as much as 7 psi increase with the converter locked.... 5 psi with the TCC unlocked. That just goes to show you how inefficient the closed front end of the TTA affects the efficiency of the IC....that little problem I'm going to address this winter with the help of DC Tech here in KC. As for spool up time, using the NOS was the main reason I also went this route....the shot OE converter really takes a while to get to full boogie.
