Zex perimeter plate

[racer3]

Has anyone tried this plate ? And if so, how do you like it and have you had any problems?

[flames4me]

just as a reference for people who don't know what it is...

I've never tried any Zex products.I was always under the impression that they sold ricer garbagie?(I'm not trying to flame anyone who may run it,and that is only my "opinion" )If they really sell for $575 as posted, I wouldn't waste my time on it.I have run compucar(junk) Nos(selling crap w/ name recogniton) and NX(by far the best nitrous solonoid and plate I have used). NX is a much better product for about the same price. Just my .02 on the matter .

wow, i thought zex perimeters were the way to go.

who makes the best plate systems? jam reckons nx. anyone else??

by the by, I'm running the NX twin gemini perimeter plate . For the record

[hammered54]

use what ya got!! been using NOS for year's no problem's, if it need's to go faster just put more to it, it's all in the tune up in my opinion.

The tune sure will help, but if your running pencil neck tiny noids..... it won't matter what jet ya put in it. True or not?

I'm curious as to where this statement originates? It seems to be a common feeling that somehow lots of nitrous companies run undersized solenoids. Which really just isn't true. The only N/X solenoid I can think of that is significantly larger than most others is one of their fuel solenoids which is around .312" I believe. But on the nitrous side you can only go so big on the orifice before the coil can no longer open against the pressure, typically about .125". You can go bigger but it requires either a much larger coil like the 30amp one on the NOS 16010 (.156") or a type of two step plunger that requires a slight pressure differential to open. Those types however usually can not be pulsed.

Some people see the smaller solenoids such as the NOS Super Power shots or what Zex uses in some of their stuff as inferior for the simple fact that it is small. It seems that people are quick to buy into other companies marketing hype when it comes to solenoids. Some companies will only carry larger solenoids possibly for several reasons. One is it easier to have one large solenoid that is used in all your kits which cuts down on inventory overhead as well as it cost less when having to stock multiple styles of solenoids when placing orders with vendors. Now assuming company only stocks large solenoids it is in their best interest to convince the market at large that the smaller solenoids are somehow inferior in quality. Similar to a company that only offers wet kits telling you that dry kits are unsafe.

Now there is something to be said about larger solenoids having less pressure drop and therefore making more power than a smaller solenoids with equal jetting. But the perception that they are somehow inferior just because of their size is to me misguided.

IMO, it's not really an inferior issue but rather an amp power rating issue. So many of the late model EFI cars run such high water temps and cramped engine bays that the temp of the noid is raised considerably compared to cars of past years. This is turn causes increased electrical resistance at the noid itself. I have had a lot of issues with the small noids not opening on my Corvette, and not just one brand. My rec is to run solenoids with like 10/12 amps as min rating.

I did a lot of testing with temp guns, different locations, different mounting like off rubber isolation mounts, and still heat sink under the hood was an issue. Some of the small noids on the market (not NOS) won't even open if the pressure gets much above 950psi, then add the engine bay heat sink and it really causes issues.

I have been a long time NOS fan, and was an early adopter of the dry 5177 kit on the Vette. However, I have come to the conclusion that the Powersport solenoids are not the best choice for a late model EFI car. IMO, they just don't have the power rating to over come the heat sink issue along with any pressures over 950psi, and then consider wear/tear after a couple years. They just don't always open. Does this make them inferior, not really, just not the correct choice for a car with heat issues. I have wished for years that NOS would offer the 5177 with their better more powerful solenoids. I believe this to be the real reason that some companies have chose to just drop the small solenoids altogether, and not a conspiracy to make more money, LOL. NOS in general is still in my top 3 companies for quality. I have had issues with not opening with other brand small noids too. I only use them for purging these days, and even there they don't always open due to heat.

Now to the ZEX perimeter kit. I think the perimeter style kit to be superior to the spray bar type kits. they allow better off the shelf a/f ratio per cylinder than do other spray bar type kits. You guys should check out the new perimeter kit from Nitrous Works if you want the best cutting edge plate kit. Also, HSW has adapted the perimeter tech to their EFI plate kits and believe this be superior to other style plate kits on the market due to better atomization and distribution. Perimeter is the way to go, IMO.

not sure what solonoid's he is talking about, but even the "pencil neck" noid's will have a hard time overcoming extremely high bottle pressure's they are rated at a lower amp draw, the old power shot may be what he was refering to, they were rather small ,nos for a while used them for purge noid's when the superpower shot replaced them, and there good for 175hp+/-(which is a pretty healthy shot!!)

[racer3]

Alot of good input on this topic. So it seems to me that flow is more important than the delivery of the nitrous. So a fogger manifold with large solenoids would be the best way to go?

Funny those where exactly the noids I was talking about. I was unaware that nos changed em. Gee, I can't figure out why they woulda changed em?

SOMEBODY SAY TITS?

"who makes the best plate systems? jam reckons nx. anyone else??"

The best plate companies out right now are wilson pro flow and speedtech thats what most of the big dogs are using

[hammered54]

right! smaller noid's will only flow X amount of no2 no matter what plate your using true. but using a plate with more hole's will help to atomize the mixture better no matter what noid your using, I use the NOS cheater plate's for a single carb applacation 32 hole's with NOS super powershot on each carb(2 660's) each is able to produce 175+/- hp @6psi

[flames4me]

they might be talking about what the plate is rated for compared to what the solonoid is rated for... 400hp capeable plate mated with a 250hp capeable 'noid will be limited to 250hp shot for obvious reasons. is this what you were thinking of with the pencil-neck solonoids you were talking about?

[flames4me]

yea, thats a safe bet you will have a good reliable setup with a fogger manifold and big 'noids.

[hammered54]

yep! a good relliable set up and a fogger with big tit's um I mean noid's!! yeah noid's that's right noid's!...........

[flames4me]

lol, make the world a better place and make all of our threads about tits, i mean nitrous.

[JAMZ87SS]

I have heard alot of good things about wilson also.

[quicktruck]

I was running the Zex perimeter plate system on my s10 with a RPM air gap manifold and it flows great! I loved the system and I think it was totally worth what I paid. I got it off of ebay brand new for $475. They use large solenoids, can handle a progressive controller pulsing them and it does a great job of distributing to all the cylinders. I traded the truck today for a monster truck though.
