100 Dry Shot on Stock pump/injectors/etc..

Re: 100 Dry Shot on Stock pump/injectors/etc..

does anyone else see something wrong with how the spray is ran? i have my nozzle going into the side of the round neck of the whisper lid. it seems your would not be nearly as effective having to take a turn like that? anyone else agree with this? one of my friends had his hooked up like that on his trans am, after i talked him into moving, he said it it felt like a world of differance.

i really dont see why to much bottle pressure would matter. i know to little and you arent getting the full shot. it dont matter how much ur pressure it still only lets the same amount of spray through. im sure its just consistantey of the shot makes the differance. having enough pressure just keeps the shot from cutting in and out. im sure it makes it feel like it hits harder though. what turned u against it all the sudden. dont get me wrong i know its a risk, but a calculated one. as long as u take the saftey procautions you could stop anything major from happening.

i foresee a new thread in the near future, jut by reading this quote above ^^

"i blew my motor, but i dont understand how or why"....


i would highly recommend u pull off or disable your n20 system until u do some research and gain some understanding. :spank:

I'm with you on that. If he is worried about the motor, but doesnt have much money for safety equipment, I wouldnt run nitrous at all. The only people I have ever known that blew their motor with spray was when they cut corners and didnt have what they needed to run it safely on the car.

Yes, I see that being a problem too. BobDole, I would move your nozzle to the neck of your Lid.

Re: 100 Dry Shot on Stock pump/injectors/etc..

The kit instructions indicate this as one of the ideal places for the dry nozzle.
The Harris Speed Works: Sudden Impact dry kit was made for LSx motors and the instructions actually diagram installation on an aftermarket lid such as SLP or Whisperlid.

I originally would have placed the nozzle in the neck about 3 inches from the MAF for a straight path to the MAF. Then I read the kit instructions which advised 6-12 inches from the MAF is best. The location I have chosen is actually a little closer than 6 inches, but was clearly indicated as a recommended spot. Depending on who you talk to on this message board, you will find that some would recommend placing the dry nozzle as far away from the MAF as possible.

Under 800 psi, I get surging or a weak hit. Take it up past 850psi and it hits pretty hard (950psi is recommended for the kit). For what its worth, the kit maker also recognizes that most users remove the MAF screen too. http://www.harrisspeedworks.com/inst...n%20Manual.pdf see installation instructions as they are very helpful for any dry kit on an fbody (might have to register/login to hsw). The position I have chosen still allows the car to run rich even though it is around that bend.

When in doubt, stick with the kit instructions, right?

If thats what the instuctions say then okay, but I would check out LS1tech and see how those guys set up there nozzles. I've just never seen that before.

i would recommend that yall dont say something when yall do know all the facts. i know exactly what i am doing with my kit. i know im at risk of messing something up. i had a grandprix that i messed a tranny up with becuase i didnt have a window switch. when it ****ed up i didnt blame the spray, i knew it was my fault. all im saying is people have done it successfully and it is possiable. you could say that any mod coule break your car, the point is know what ur car is capabale and be ready to accept whatever happens to it. i personally believe i have a better feeling for my car without the window switch. as for the fpss, i prolly do need it, just a risk im willing to take.

Re: 100 Dry Shot on Stock pump/injectors/etc..

Dude, I'm just simply telling you what happened to others who were cuttin corners with nitrous. Maybe your car will run fine, maybe it will blow to peices, 50/50 something could go wrong. 50% chance that you could spend up to $2500+ for a rebuild when a $35 dollar could have prevented it, not good odds my friend. Thats all I'm tryin to say. :)

For what its worth, the way I see it, you are totally fine doing what you're doing. You seem to know what you could be getting yourself into in the worst case scenario, so I am 100% behind your decision to run the 100 dry shot on stock fuel system. The thing is, if you do end up locating a weakness in the stock system, your experience could help many of us here.

I would have never gone with the HSW dry kit if you had not run it and posted your experience with it first. Everyone tells you what you may already know (what you are risking and the popular opinion on what may happen), but you push forward into unknown territory.

You are a pioneer :tup:

I wish you the best luck. You have to understand that after so many V6 motors have blown, members of this forum can get very protective and not want to see it happen again to anyone else. They're looking out for impulsive guys like me who can get a little carried away with the nitrous after sending just a few pounds through the motor.

When my disposable income hits a certain point in May 2007, I am going to mod the **** out of this poor car. I have a long term goal to build a solid high performance NA V6 motor that can pass smog (California) and handle a 150 shot.

Re: 100 Dry Shot on Stock pump/injectors/etc..

i appreciate that, hopefully i wont run into any troubles. but like you said, i know im at risk. i currently looking for a good nitrous cam in hopes to bumpin up to like 125-150 (with the appropriate saftey checks of course ;) ) Good luck with your car though. forrest

Re: 100 Dry Shot on Stock pump/injectors/etc..

Good luck fellas, I wish the best for both of you. I am just tryin to give you the statistics on what has happened to others and dont want you to make the same mistakes and have to spend a ton of money to fix your car.

Bob, keep us updated once you dyno your car. :burn:

Re: 100 Dry Shot on Stock pump/injectors/etc..

i blew a head gasket running a 100 shot on a stock fuel system.. one word of advice.. don't do it

Re: 100 Dry Shot on Stock pump/injectors/etc..

SO wait, you want to run a 100 shot on a stock fuel pump?
-Ok, I could see that. I have done it.

BUT, you don't have a FPSS?
-This is stupid. It saved my ***, and its cheap.

Soooo, doing both together?
-That is what is called being young and irresponsible. You are cheaping out in two huge areas for 25 more HP? Its not worth it my friend, not at all. When you grow up, you will look back and say, "Damn, that could have been bad. What was I thinking?"

BTW - Surging is usually not a bottle pressure issue, it is a solenoid or fueling issue.
Good luck.

Re: 100 Dry Shot on Stock pump/injectors/etc..

i could give 2 ****s about what u think about how i run my nitrous system. i have been through two bottles about and no issues. yea i know im taking a risk. as long as i know this and dont plan on just blaming the spray if something happens i dont see why it would even concern you. the point of this thread was someone asking if you could run a 100 dry shot on a stock pump. all i was saying is that its possiable, although not recommened. if someone wants to and feel they want the saftey measure of a fpss then fine, if not then nothing wrong with that as long as they know the risk. so dont go judging someone and calling themn irresponsible just because they dont do things your way. thanks and have a nice day:)

Re: 100 Dry Shot on Stock pump/injectors/etc..

Not using a $30 peice (that is free on most respectable nitrous systems) that could save your engine and all the work that comes with replacing it is totally irresponsible.

I went through 2 bottles on a 100 shot and a stock fuel pump, but the FPSS saved me when the pump went. Its not a matter of if it will fail or not, its a matter of how long it will hang on.

I could give a damn less how you run your setup, I hope you do blow your motor up on principle, but don't come here telling other members bad ideas.

Don't get so defensive pal, its only the internet.

EDIT - FWIW that kit comes with NO safety features that most kits include, such as FPSS and a second safety nitrous solenoid.

That is well worth pointing out. It is a bare bones dry system that retails for under $310. HSW may be asking for trouble, but then it is a dry system activated with a micro WOT switch; the potential problem is failure of other components in the car, right? I don't think that would weigh negatively on HSW. I question the PowerMax solenoid though. I left the valve on the bottle on over a 3 day period with the car parked. The system was at about 800psi with the bottle out of direct sunlight and under a covered car port. It leaked a small amount of nitrous through the solenoid and into the intake. That was a real annoyance, but I guess it is common which is why people keep the valve closed.

Matt, how did you blow a head gasket? What was your RPM and bottle pressure?
Was was the condition of the engine before it blew the gasket? I used to blow head gaskets constantly when I modded and raced my 4-banger mitsubishi cars. I don't like the idea of oil and coolant going where they don't belong and I can't stand seeing oil on the driveway.

As for the dyno... it never happened. Apex Motorsports is run by a bunch of flakes. I'm going to dyno-tune it after I find a reputable shop that can monitor a/f ratio accurately. I'd rather spend a few hundred and know what the car is really doing and be able to get it to run right rather than to spend $95 just to see how its running without a tune. I should be able to remove speed limiter and adjust torque management with a dyno-tune, shouldn't I?

I'm due for a dyno-tune. I've run 4 bottles in less than 2 weeks. I prefer to dump what's left in the bottle when it doesn't warm up to 1000 psi without getting so hot that it burns my fingers (on the heater). The fresh fill is worth it. When I run a report on my spending later this month, I'm gonna flip out when I see how much I dumped into nitrous.
