how much spray can the plastic intake take?

MaroonMustangGT · Jan 9, 2006

gonna order a vt short block and planning on running a 200 shot. can the plastic pi intake take it? or do i need to go bullet?

Might as well just do the Bullitt swap and avoid the "damn.. why didn't I just do the swap" thing later.

That's awhole lotta spray.
I've sprayed 150 3 times and wasn't real excited by it. I think JayC does 150, sometimes.

On the topic of spraying, I'm running a 98 GT and I would like to run a 50 shot from a NOS wet kit. How will this affect my bone stock GT? What all do I need to do to give this car the highest reliability?

a 50hp wet shot???
might see 2 tenths in the 1/8 reduction. Not 100% sure never sprayed that lil amount.
Most beleive up to 100hp shot isn't really gonna affect it too much. Of course if your spraying ALL the time then it could.
If your wanting to stay with that low a shot you may want to look into a dry kit instead.

Nice, pardon the freaking newbie question, but what would be the difference in installation between a wet vs. dry kit?

Wet you need to tap into your fuel line, dry you don't.

I don't think it is the amount of nitrous used that kills the intake, it's back fires caused by puddling. I'm ot nitrous expert, but I think i'd invest in a nozzle system to avoid the puddling before I'd invest in a bullitt intake.

I'm with ya. I've never played with nitrous before, and I'm not thinking of going with a 50 or 75 shot - DRY.. just something to have fun with every so often when getting on the highway. My only concern is that I'd probably use the nitrous so seldom, that it may not be worth the hassle come summertime (having to remove the bottle frequently and such).

Before I ever run nos on my car, I think I would go ahead and invest in a good intake for my car, and try to elimate the problem of haveing to fix it after its already broke. Especially if you plan on hitting the giggle gas on a regular basis .

QU!CK · Jan 10, 2006

You can run a 300 shot but don't expect to use it more than once

Try it twice and you'll be on the road side sweeping up the legos, er, intake manifold peices

Well here's the deal. My buddy put a wet system in his Supra, and took it out because he wanted to break into the 9's without NOS. So he's going to part with it for $200 to me. So I need to get some additional pieces and find out exactly what I need to hook it up before hand. This is something I'm interested in only if it doesn't leave me walking. What do you think, deal, or not worth it?

VicRattlehead · Jan 10, 2006

50 wet shot......

its not the amount of nitrous, its the amount of backfire thats the killer

btw

zerosgt READ THIS!!!! http://tccoa.com/articles/misc/Nitrous/N2O-FAQ.shtml

IMO, if your even thinking about any N2O you HAVE to have some sort of computer program in place to work with it.

Guys, let's get all the facts out on the table.
First of all the plastic composite 4.6 2V intake manifold has known defects. Ford just settled a class action law suit regarding the intakes failing/cracking at the seams due to heat. Read more on that here:
http://www.fordmuscle.com/blog/ford-settles-manifold-lawsuit/

Secondly, in any NOS system, wet or dry, a backfire can destroy the manifold...and anything else that cant hold the pressure. This could be the air box, the air ducting, and sure even a piston or head gasket.

However, in a wet system, where fuel is running through the plastic intake, you have another problem...and that is incompatibility of the compositie material and gasoline. Those intakes were never designed to carry fuel. Fuel makes the plastic brittle, and sure over time it can become weak and crack.

I've run a 150 shot on my 01 without issues, but I don't use the NOS often.

I think if I ever wanted to use it repeatledly I would step up to a aluminum intake. Professional products is introducing one in a few months:

FYI, this article is must read if you haven't done NOS on a mod motor:

All true stuff there.
Zero- If it's a got a bottle, working solenoids it's worth that much. You may have to do some research and order jets but that is the only thing I can think of off the top of my head.

what he said.

zerosgt · Jan 11, 2006

Wow, you guys are really on top of it. I'm looking into upgrading my intake anyhow (due to it's lame abilities). So would it be better to do a dry kit to avoid the fuel eroding the plastic intake? I'm really not keen on the dry idea.

Any other manufactures that make aluminum intakes for the non-PI heads 4.6 or do I have to do that upgrade as well?

jimfitzgerald · Jan 11, 2006

The plastic intake is not the real issue with nitrous. They are cheap and easy to replace. The real issue with nitrous is not to burn up one or more pistons due to running lean. IMHO a wet kit is best because you are spraying both nitrous and fuel and with a good tune you should be OK with up to 150 shot I believe. Above this, it starts to get risky.

The intake issue comes into play if you get fuel puddling in the intake resulting in a fuel explosion in the intake. This will definitely destroy a plastic intake but I have also seen it destroy a Bullitt intake and a MAF meter. Fuel puddling is more likely with a wet kit, but I would rather buy an intake than an engine.

If I was going to run nitrous, I would get a wet kit and buy several used plastic intakes and stock MAF meters as spares. This would be much less expensive than a Bullitt intake that you might blow up anyway.

Sounds like good advice. I still want to drop an aluminum intake in it, just because. I found a company that's putting one together and I told them I'd be a tester with a Nitro kit. Let me know what you think.

I would not buy anything unproven. Also, just for your information...

N2O = nitrous oxide
NOS = Nitrous Oxide Systems (a company)
Nitro = nitromethane

how much spray can the plastic intake take?
