11-19-2002, 10:09 PM

I put some MT ET Streets on my car and went out for a nice little test drive. OH MY GOD. that was the hardest launch I have ever felt. So I went home to go get my little brother and we went to a good road to do it on. then about 1 second later and BOOOM . it sucked bad super bad. well it was running so I drove it home and I opend my hood and blam I had a hole that was about 12 inches long and I was like good greif that is a new intake. here is a pic. I would love somebody to tell me that this happend to them to.

haha you got it easy compared to the one that i had this past year in my old 89 GT. It blew my new harwood hood off, blew my intake off, burned the front of my car..it sucked. REALLY bad.

HOLY CRAP DUDE!

that sucks. im sorry that happened.

im sure it'll happen to me sooner or later.....

would the boxed upper intake prevent backfires?

Dark_5.0 · 11-19-2002, 10:55 PM

Are you using a wet or a dry kit. Lots of people have trouble (Backfires)with the wet kits on EFI vehicles.

Now you have a cool piece of junk you can show off

Later,

Yes it is a wet kit
yes it is going to be hung on my wall

If anyone would like to donate money to the "buy brad a intake fund" I accept cash, money orders, paypal and frontal nudity

how the hell was that running????

bri32zz · 11-20-2002, 12:21 AM

Hey I have an Intake u can have, a ported stock intake if u want it just pay the shipping and it is yours bro. Lower is ported too.

bri32zz · 11-20-2002, 12:22 AM

It is off a 95 do not think it will work for you though

sn95gt19 · 11-20-2002, 01:14 AM

yeah, i have heard of a lot of wet kits doing that. i guess the fuel can pool up in the plenum, and ignite. (as you learned first hand) if money permits i would go with the plate kit that goes under the intake if i were you. good luck!

ultraflo · 11-20-2002, 02:58 AM

Whoa! ....thanks for sharing the pic.

I'm building up my own fund right now, or else I'd contribute

red82gt · 11-20-2002, 03:02 AM

OMFG! That's pretty rough man. A guy I know has killed two TFS track heat intakes. I'm surprised they still sell the wet efi kits, I've seen a lot of carnage from these ticking time bombs. another vote for the big shot plate between the upper and lower.
Also is the other piece one piece or is it shrapnel? There is an outside chance that a good welder could patch that up.

cyberstang5.0 · 11-20-2002, 08:00 AM

That's a bad way of getting to the inside of your upper manifold to machine it...

chris91LX · 11-20-2002, 09:37 AM

Holy crap! Bummer, 801.

I think I'll stick with my dry kit for now.

Nitrous Al · 11-20-2002, 11:30 AM

I blew up my last intake just like that, but I didn't take any pictures. Got to love those wet kits. Next time, I'll have a shop tune it for me.

Come on now!

...wet systems work great properly tuned, of course.

Obviously you just can't plug and play with a wet system like you can a dry kit... there is more skill involved with tuning a wet kit, IMHO. I've read countless posts where Joe Schmoe can't figure out why his new nitrous system doesn't hit like he thinks it should... ask what the bottle psi was, for example, and you get either, "don't know, don't have a gauge"... or, "it was around 600psi." LOL... and then they wonder why the system is sluggish and/or fuel puddles in the intake.

All too often the wet kits get a bad rap because of operator error... [/rant]

bri32zz · 11-20-2002, 12:34 PM

From what I understand a custom flip chip is the best way to run with a wet kit. I have a toggle switch in my glove box for when I run my wet kit. It allows the computer to react to the wet kit. With dry kits the computer picks it up. Since u are shooting fuel with the n2o your computer will not compensate for the extra fuel and it need a seperate program for it. I was also told if you shoot juice with a blower it has to be a wet kit or else you will run way tooo lean and you can say by by to the pistions. Welll I am off to the hospital now for my biopsy see yall later

red82gt · 11-21-2002, 02:35 AM

Ultraflow, I think you're probably right, the guy I know who blew up two tfs intakes was complaining about how his car slowed down when the bottle pressure dropped and someone had to tell him that the Nitrous/fuel ratio is off when the bottle pressure drops, that's why his car was blowing up intakes.
If I owned a nitrous company I'd sell only a dry kit for the Ford efi but I'd make a conversion kit for a wet kit, that would keep some of the ametures away. IMHO the efi long runner intakes are not good at flowing fuel and the 180 turn after the throttle body inlet is a prime place for fuel to puddle and it just leaves no margin for error. I like the NOS big shot kit because the lower intake has much better potential for flowing fuel than the upper. I think if you want more than 150hp from the spray, go with the big shot.

PKRWUD · 11-21-2002, 03:39 AM

This is precisely why I recommend dry kits for nitrous newbies, but I still get crap from people for it.
