Need Help!

[03BCLIGHTNING]

I just recently noticed this the other day, everytime that I give it hard gas the L sounds like its missing. I sprayed it about 4 months ago and i havnt changed the plugs so i was thinking that was my problem. :mad:


Any Help!:tu:

[PoorSvtman]

pull the plugs and check them

[03BCLIGHTNING]

well i know that but anything else that can be a problem!

[PoorSvtman]

Bet you killed a plug... Go out and pull them.. heck might as well change them while your at it...

What plugs are you using, also do you have a tune for your spray?

[03BCLIGHTNING]

NO!:mad:


Can i do that with the tuner that i have? black box (3)

[03BCLIGHTNING]

another thing...i changed my rotors and whole new brake job but it still sounds nasty! it sounds like something is grinding and when i stop it does it also! Do i need to do something to break them in?

[PoorSvtman]

NO!:mad:

You can get a custom tune for your spray which you should have done.. Also for the brakes i dunno id have to hear them. Did you put new wheel bearings and new grease in the hubs? Are they slotted,dimpled,cross drilled rotors?

[03BCLIGHTNING]

na i was going to get the drilled and slotted and that other good stuff but i heard that they crack so i just got some regular ones! Yea i put all that but there is still something there. Where in arlington r u?

[03LightningRocks]

No doubt about it, you fried at least one plug and maybe more. Timing must be taken out of the tune for nitrous. You might even cause valve damage if the plug tip breaks off.

Mike is on target in my opinion. Get Terry to set you up with a nitrous tune before you spray again.


P.S. Never again listen to whoever it was that said you could spray without adjusting your tune. They have just proven that they don't know sh!t about modern tuning and supercharged motors.

[03LightningRocks]

One question for you. Did you go with a wet shot or a dry shot?

[03BCLIGHTNING]

Wet! i didnt have any problems but i guess i should have changed them as soon as i stopped spraying it!

[03LightningRocks]

Wet! i didnt have any problems but i guess i should have changed them as soon as i stopped spraying it!


Wet is good....;) . For me, I feel like the plugs should all be checked everytime it has been raced using nitrous.

Be sure and get that tune before using the spray again.

[03BCLIGHTNING]

yea ill be sure to do that! thanks!:beer:

Just remember nitrous can be a good thing, but something can go wrong and when it does bye bye motor.

That guy could have really screwed you by not telling/helping you with a nirtous tune. Your lucky that there was not any major damage! Rocks is right you need to adjust your timing for the nitrous.
Like rocks said "have terry help you with the tune" most of everyone would say he is the MAN knana

I sort of agree with Rocks except we don't have enough info to actually say this. We don't know how agressive the tune is/was and we don't know how much nitrous and timing. For example, a 50hp shot from the unit Rocks runs would only need a reduction in timing if the tune was super agressive. I'm not arguing but we should know all fact first. As for the plugs, that's where I would look first.

Guess again!!!!

Please explain Rocks. I've run your unit on plenty of cars including SC'd mustangs without doing anything. We tried 75hp on my car with 12lbs of boost and the only thing that blew of were the tires. Keep in mind that my Mustang is as fast as your truck. It's not like I squeezed a stock car.

Your truck might be a little different because you're already running a built motor, a KB, tons of boost, and 10's. I have no idea what 03BCLIGHTNING has got going on.

He hasn't given up alot of info on his truck, but I believe he is running a 4lb lower and a race tune.

One thing to keep in mind. The rods in these 5.4 motors like to come loose. Even inaudible detonation can take our stock motors and turn them into scrap.

Another HUGE factor is that a Lightning weighs 5000 lbs. The load that the motor gets put under when making a 5000 lb brick run 10's far surpasses the load that a motor in a Mustang gets put under.

There are a few things I have learned about racing,

1. The rich can afford to pay and get the work done right the first time, because they pay to have it done right the first time, instead of short cuts and cheap work which results in more expensive work later on when things go south

2. N.O.S. is like a hot girl with an STD, you want to hit it, but you are afraid of the consequences!!

3. Speed equals money, you have to pay to play

4. Cheap fast work = it wont be good
Cheap good work = it wont be fast
Fast Good work = it wont be cheap


You can get by running N20 with a programmer returning it back to your stock or cold tune, to decrease the timing, but you will never see the full power gains and you wont ever run the right mixture of N20 and fuel, which means too much fuel, too much N2O, its not a matter of if it will be ok, its a matter when it wont be, hopefully its just the plugs and you didnt lean out and scar a cylinder wall, throw a bearing, or something alomg those lines

[03LightningRocks]

Snip.....

You are not really that far off Michael. It is not something I would say is recommended though. One of the items that can be done by tuning is to lock in a WOT timing setting. This can insure that you are actually at, say 14 degrees of timing. Let's say for instance you are running on a cold day...the stock program adds, say 2 degrees of timing. Now you wack it with a 75 shot. Oops...too much timing for the nitrous. To briefly address the lean issue, when using a wet shot, your fuel is being added with the nitrous, so there is really no need to mess with the fuel curves in the tune.


All that being said, yes, I have heard of folks switching to a stock or "street" tune to avoid getting a proper nitrous tune. Problem is, unless your set up has been on the dyno and or data logged, you are really just hoping for the best. This is a big risk when talking about blowing a motor....IMHO

Rocks,

Thanks for the explanation. I'm not trying to be argumentative, I just want to learn what is what. I am very aware of the rod situation with the L's, and also, I know that my mustang weighs 2900 and my L weighs 4600. I just thought that bad mouthing a tuner without all the facts wasn't the most logical thing to do. Terry laid into me a couple of months ago because I thought a small dry kit was a good way to go but now I know better and I have a wet kit for my truck. I can't learn if I don't ask.

oops! i messed up on that "quote"

Well you get it anyway! :hammer: :ron:

Your still my boy Ronald....oh no i might have started again! :eek2:

Rocks:beer:

There is no doubt the benefits to a proper dyno tune, espically when N20 on top of a blower is in the equation. Think about how much power our trucks are putting out, now throw N20 in the equation, thats alot for a motor to handle, espically if its only "parking lot tuned" and not dyno tuned. I know Ken Cryder ran his big shot for a long while, but in the end his motor blew, and if I had to guess his was dyno tuned, and he had run N20 since I had meet him back in Nov. of 2002. Like Uncle Rocks said its just hoping for the best, and thats usually not a good thing.

Also if you are running N20, or race fuel you need to change your plugs very often, and fuel filter after every or every other time you race. :ron: When Adam and I went to Hallsville back in January 05, I had never changed my fuel filter, I had roughly 15,000 on the truck. I had run roughly 20 gallons of race fuel through it, and on the way home from running low 12.2's my truck kept acing up wanting to turn off. Turns out my filter was completly cloged. After that, every time race fuel goes through my fuel system it gets changed.
