a buddy of mine is doing something i think is a little nuts, everyone else is telling him he is nuts too but he is very sure of himself. he wants to run a 10sec 1/4 is the thing.

here is what he is doing.

150 TNT shot with window and wot switch, 100nx wet shot on top of that on a seperate button in his hand, he is going to spray 4500up with that. here is the bad part. NO TUNING at all. stock long block, 100 octane. he does have a fuel pump.

is there anyway this will work? i could see a 250shot with some tuning and better fuel.

I would definately run more than 100 octane with no timing pulled. And throw in some colder plugs to fight detonation. What car/truck and year is he spraying?

He is going to have distibution problems and melted pistons. Its not so much not having a tune that will kill it. If the jetting is Ok. Also he might still ahve to much timing for that spray on a 250 shot. Also even if it does go off w/o a hitch I would not expect great results. Just a bad idea relly. Now with a fogger setup and the right amount of timing pulled i would say go ofr it and give it a try. A progressive would be really nice too.

it is an 02 camaro. the plugs are another thing, he has tr6's in there but that seems to hot for a 250 shot. i dont know much about bigger shots but it just seems like a bad idea to me.

i think we can get 105 unleaded. it would still be nuts even with that wouldn't it?

Are you going to be watching for knock. It seems fun and cool but if it is done bass ackwards then its not cool. I would say go a little colder just for the n20 passes. Maybe even a plug that woul foul on the motor alone. I still think the eal thing to worry about is distribution. then agian I think I have seen cases were someone hit there car with 300. Then agian the had alluminum on the plugs after the first run.

If he is willing to shoot a 250 shot with no tuning then I think he wouldn't mind possibly ruining some o2's for the sake of safety. Run some C16 in that bad boy with some TR8's gapped down tight and see what happens!

Right. that would be the way to go about it for sure.

yep...on a stock tune with C16 he will be running pig rich (possibly covering the leanest cylinder). I think as long as both stages didnt come on at 3000 rpm together it will work.

I think he should fill the tank when he gets to the track...I doubt it will run for long like that. Fouled plugs and 02s for sure.

He should just put the second stage on another window switch to come on at 4500. That and some good gas and I think he could do it easily.

Make sure you take your trailer with you

Forget the C16. I would run some Sunoco Supreme N.O.S. That will greatly help the detonation. I would also run the first kit on the rich side, and run the second kit "straight up" on the jets. You don't want to shock the motor at all.

I've heard of that but what is it exaclty?

Jeffrey, it's right at 120 octane leaded, with around a .725 or so specific gravity. Good stuff for nitrous motors. We have a drum of it at the shop if you want to try some.

Might just have to try it pretty soon.

NGK -8 plugs gapped at .032
pull 3 degrees of timing out if at all possible
1st stage on at 3000 rpm, run one jet rich on fuel side (150)
2nd stage on at 4000 or so, standard jetting (100)
dump exhaust if at all possible (i.e. cutout)
have nitrous shut off at 5800 or so...

big sticky nasty tires

Oh, yeah...the most important thing...tell your friend to sell his Camaro and get an import, that way he can talk to EVERYONE about throwing a nitrous kit on his honda and running 10's

P.S.,
I thought about the truck thing you have done...very nice. I wanted a std. cab, 2wd, with 4l80E and transfer case out of 3/4 ton....just like you did...Very nice setup. I would hate to see your truck on the street and only beat it by a couple of cars while on the hose! That to me would be just as bad (or cool, depends on how you lok at it) as loosing to a more traditional car (i.e. viper Vette, etc). I imagine you should be in the low 10's with the 408 and more boost/nitrous.

I can't remember what stock timing tables are for an 02 but it isn't very high. He will probably be fine with the timing. I would run some 112+ octane fuel and TR8's

I run 18 degrees total timing and use TR8's gapped at .032 with my 300 shot. I am making alittle over 700 to the wheels and 800lbs of torque.

Ahh is the camaro on a 12bolt or 9in. If not forget the sticky tires and whatever comes with it.

I think the rear is going to be the least of his problems. :jest: I'd say the stock rear would hold that kinda power and stickies for a pass or two at least. Whatever you do don't forget to video this I'd seriously like to see what happens. I bet it's doable but I wouldn't wanna be the one to test it.

At the minimum he needs a Timing Tuner. I also recommend NX's chemical X. I ran it last week on a 200 shot on the stock shortblock & got no detonation & it really did feel faster. I also got a new best NA time with the Chemical X in the tank. I also ran a new high trap speed on my 150 shot with the chemical X in the tank. My bolt on car with a 150 shot trapped 123 in the 1/4 & the DA sucked it was around 2250' when I made that 123 MPH pass.

I have the pills for a 250 shot for my stock shortblock motor, but weather & track conditions wouldn't let me run it.

Ive seen it done before, a buddy of mine had a 250 shot on a 2001 ws6 car just had minor induction stuff and a cat back on slicks and i think he ran liek a 11.40, Im not to sure how much of a clean shot it was though he had 2 foogers stabbed into the air intake before the throttle body. I cant remeber if he ran it on race gas or not i dont think he did though.

Just dont tell him and go stick one of those resistors in his IAC just to help him out a little.

we did 300 shot around here in my buddies '00 WS6 the first week he had it. He had a custom single stage dual nozzle NX kit and ran a 50/50 mix of C16 and 92. The car had a lid and TR6's.

It ran great for about 2 weeks and ~10 bottles, then it melted a piston and backfired sending a nice fireball out the front of the intake destroying the MAF and lid. Car ran 11.34 @ ~128ish on slicks, ran a 13.8 @ 134 on street tires.

we went out and did a few runs with efilive hooked up. i am prety much amazed. below is a screen shot of the last run. at about 4000rpm the 150shot kicked in and around 4800 he hit the extra 100shot. this is with 92 octane. he the 250shot running for at least 3 sec and there was no new knock during that time. he did get a little knockretard when he first hit the 150 and there is a nice lean spike on that first shot. 31.5deg of timing up top too. :eek2: . he is going to the track on friday and this will be on video. should be interesting. he will also be running a set of the MT drag radials.

because he is a nitrous expert and there is nothing to learn here that he doesn't know all ready ;)

My buddy sprayed a 150 shot with msd digital 6 iginition to pull the timing, but he didnt wire the msd right and it backfired and blew a hole in his intake manifold about 10 inches wide and 3 inches tall.....o wait that was in a mustang...tell him to go for it! :rock:

10-06-2004, 03:39 AM
ouch.its not that bad.a friend here ran a 2 stage maf plate set up.shot the 1st stage out of the hole not sure how big got to the end of the 1/4 mi. all we see was white smoke all over.got towed to the pits and after checking a rod dicides to let go and punch a hole on the pass.side of the block.now that hurts.

10-06-2004, 07:09 PM
Yea a rod through the block isnt ussually a good thing...then again we have no idea how my friends internals are except for they are still inside the block...he was going off to college right before so it hasnt been worked on...
Another reason why im only goin 100 shot :nod:

parish8
10-08-2004, 05:57 PM
it is time. we are all on the way to the track shortly. he is nuts, going with a 150 tnt about 1/2way thru 1st and then add 75-100nx at 4500+ in the higher gears. tr6 plugs, 105 fuel, full timing. :bomb:

should be interesting. there will be video if anything cool happens.

I'm curious how this turned out.

Also a comment - looks like a possible uneven mixture problem brewing from the difference in the O2 readings on that EFI chart.

Probibly no he only little problems brewing either huh Deezel.

he didn't blow it up. he made one hard run and messed up his clutch or tranny. i am not sure of the exact problem. he did pull a good 60' of 1.71 and ran a 11.5 at 125(i think). i have think i have a vid of it but i have to sort thru the footage i have.
