Zex perimeter plate

[quicktruck]

glad I can help. I have run the NOS bar style plates and I felt like the perimeter plate did a much better job. I think the new owner of my truck will probably agree with me after he tries it out.

can dual plates be used or will I need a cross plate? 75hp first ,100-125 on the second stage.

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.

how much would you guys recomend using with an edelbrock rpm air gap manifold? Ive heard 150 shot
