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?
a 50hp wet shot???zerosgt said: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?
Wet you need to tap into your fuel line, dry you don't.zerosgt said:Nice, pardon the freaking newbie question, but what would be the difference in installation between a wet vs. dry kit?

All true stuff there.FordMuscle said: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:

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:

jimfitzgerald said: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.
I would not buy anything unproven. Also, just for your information...zerosgt said: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.
