You gotta love those wet shots. 2nd video later in thread shows the boom and the flames coming out of the front.

That had to hurt. What happened did the N2O hit while on a 2-step?

By the looks of the damage. I doubt a set of burst panels would have prevented the intake from going boom.

Spraying off the line. When ever you see them do that its always off the line. Or least all the vids I've seen. Why is that? Not enough air flow for the amount of gas being dumped due to being stationary? What causes that to happen off the line?
By the way Robert I hate it when you do that. Gets my paranoia going and makes me think my car will blow up and burn to the ground... if I ever get it back

Don't use a wet shot.

Dude I can fix it. My dad has tools, he's a TV repairman.

Is it just me or did it blow the drivers side headlight cover off too? Pretty nasty.

Not every wet shot goes boom.
But theres got to be a common reason as to why they blow off the line like that. I'd never spray of the line, my suspension isnt set for drag racing and I have serious traction issues as it is lol

That **** scares me, that is why I am ***** and use that huge 75 shot jet. I have yet to even put the 100 in.

Your safe Mike. Dry shots dont have fuel puddling issues. Although any back fire on nitrous is gonna hurt a little.

just get a direct port setup and guess what no more problems of fuel puddeling.

So what happened? Did he not have a working window switch?

Nitrous is painful if not used properly. I need to check my system to ensure its working properly before my first visit to the track.

Here's a TNT wet 200 outa the hole, on a Z06.

You got to give more information than that!!!

Were these cars using safety equipment? Your kind of scaring me with that **** dude!!!

I think I'm gonna try and wire up a system that will run my nitrous. That way the none of this **** will happen.

man, that **** scares me too.

ryan keeps telling me not to spray when the bottle pressure is getting down because of that

I guess you can hook up some systems that shut down your kit if the safe peramiters aren't met.

I need to look into this **** some more before I go boom!

Bottom line: If you got the ***** to spray, you either better have the money to stay safe or the money to replace parts when you go BOOM!!

Notice: Robert never touted once the safety merits of running a dry hit, or the fact that no can find any videos of this on the whole WWW concerning dry hits.

Wet hits are not that great at lower rpms, and even worse as you go bigger, as Ellis stated. The wet vs dry thread has a nice explanation on the raw fuel going through an engineered dry manifold. Our manifolds have two more issues, they are plastic, and the TB is at the front. So when an intake back fire and resulting explosion happens, it has no easy escape so it finds the path of least resistance-through the plastic intake. Having a below the runners plenum is another feature that is not conducive to fuel, it likes to drop out.
There are many reasons for an intake back fire, but the added fuel makes it much worse, then the the fuel rails become dislodged and spray more fuel around. Now, even a dry system will have a little fuel vapor in the intake track, because of reversion, but it will be just a hic up when an intake back fire occurrs.
Both cars had window switches, and both were spraying 200. What caused the back fires, who really knows, but we do know there was plenty of fuel.
This doesn't happen all the time, many run 200 wet hits just fine, but on occassion things can act up.

So does a direct port prevent it? Is that correct?

TwoFast4Lv

Number ONE reason wet nossle kits blow up out of the hole.

LEAN SPIKE! Almost all N2O kits come with equal length lines. N2O is at around 1,000Psi and Fuel(LSx) 60psi. SO which one getts to the cylinder first? BINGO! so now we have 1,000psi of N2O AND a big jet filling the intake. At the same time some thing(the plug comes to mind) over heats and sets off the mixture before the Valve is closed. This happens Just about the time the fuel gets there filling the intake with the N2O.

Well here we are with an intake full of N2O AND fuel while the valve is open and a hot spot in the cylinder sets it all off.

BOOM!

The main reason there is a big fire afterwards is the fuel system is still pumping fuel out every where

I have seen it with wet and dry shots.

I hope this helps you guy get a good mental pisture of what happens.

HOW can you solve this? the same way you did it 20-30 years ago. Make the fuel line shorter then the N2O line If you look closely at my Videos you will see my car pour black for a split second while the 200+RWHP hit comes on out of the hole

That is because my fuel line is only 45% as long as my N2O line

can you fix mine too? (when I come by next time)
I don't like Boom, it scares me

sardog46

nice explanation ellis. And yes alot of the problem can be eliminated with a direct port, but you still have to have the safety measures in place. one of the guys in south carolina i know has a 5.30 1/8 mile camaro with about a 4-500 hit direct port and has been spraying that for over 20 years with never the bit of a hic-up. But once again this system has all the safety switches in place.
