Why no more Fox EFI plates?

Seems like every nitrous kit I see is a nozzle or a carb plate. I canít find a EFI plate to save me life besides the occasional one used. Other genís and other cars have EFI plates aplenty though.

Gotta find them used. Nitrous isn't as popular as it used to be and EFI Fox platform is getting old..

I’ve seen those and they are nice. But I was more so talking about the ones that use to bolt behind the Throttle body. Every once in a while I see a used GT40 lower intake plate. I may wait for one of those to come up.

They had poor distribution through the long runner manifold.

The type that tjm73 posted are the way to go.

as already mentioned though, i would be careful with the higher jetting with long runner intake.

replaced the 93'ish coupe with a 76 F100, 393, 11.5:1, TEA CNC 205 TW's, custom Hyd Roller, Super Vic, 830 HP, AOD, Edge custom conv., Silverfox SPT-MAC-TB.

Thanks for the input guys. I was looking more for the th plate than the intake plate. I was just curious. You see them everywhere for LS motors. And I just figured if they wernt as good then the nozzle wouldn’t be that good. But I’m just trying to learn about them.

I did and I saw the system. Which is funny because I was almost certain I had looked at all the nitrous places and didnít see one. I like it and when/if I decide to go nitrous Iíll. E inclined to use that system.

I was in your spot last fall when was looking for n2o kit for my car. i wanted a TB plate set up too. i went with a ZEX kit and Ebay TB spacer that I tapped and put the nozzle in.

But it's not the best set up with the long runners and large plenum of the stock style EFI intake manifold to get even distribution to the cylinders. I would also assume it could increase the chances of a damaging backfire if the upper intake was full of N2o and fuel. If i decide to upgrade my set up I will be going with the spacer plate style to help with distribution.

i have run all EFI style systems available for the 5.0... spacer plates from NOS and NX, TB plate from TNW, single nozzle kits and dual nozzle kits. my $.02, i wouldnt go over 300 with anything spraying before the plenum, for ease of install the nozzles are good. For better distribution and larger, dual stage hits spacer plate. i LOVED my Nx dual stage spacer plate!

always install a good high capacity in tank pump if pulling fuel from the schrader valve (i like the 320LPH from HFP), anythying over 200hp shot i would NOT use the schrader, find fuel elsewhere (standlone or new larger fuel lines/rails).

Thanks for the info. If I run Nitrous I’ll prob never spray anything over a 150 shot. It’s a street car. I have a 340 pump just waiting for what ever I decide on lol.

Also most guys that are running nitrous are not using the OE intake (it's a turd in the pool of performance). They have moved on to way better setups. The market has dried up.

I had originally planned on spraying my car before I decided on a single turbo setup. I was going to drill and tap the bottom of the inlet runner underneath my Explorer upper for a dry nozzle so it was hidden and use my A9L to run the nitrous noid. A .076" jet would have put my decapped 19s at about 80% duty cycle. Dry setups are still a great option if you have a stock style intake.

plus i think pushrod stuff is slowly going away. it would explain why NX used to make spacer plate kits for like 4 or 5 different PR 5.0 intakes, now those are gone and replaced with the TB style kit that i linked. makes good business sense.

I don't think pushrod stuff is going away per say, but the market for it definitely shrinking. Let's be honest,the last Push rod Mustang was nearly 22 years ago and the last pushrod 5.0 was built in 2001. Coupled with the strength and smoothness and power output turbos and supercharges produce in the modular engines and the writing is on the wall. Only the faithful will remain.

The real nail in the coffin was driven in 2011. The 5.0 DOHC resigned all other Ford V8's to the faithful few who will keep their flame burning.
