I have a few used intakes locally for sale near me. Need opinions on which would be best for my setup. There's a Trickflow R with 90mm opening, a Trickflow Street burner and an older Edelbrock Performer. Car will be mostly street driven with some 1/8th mile track weekends and I plan to keep the boost around 8-10psi. Want to keep good street manners, but have some fun at the track too.

Sparky, I will tell you from experience that I should have listened to the experts here and gone with a Trick Flow Box R Series intake TFS-51511008 (see photo) from the start. I thought it would be too big and instead went with the R Series intake TFS-51511005. I regret that decision and will be upgrading to the Box R Series in the future.
Your combination with the supercharger will flow more air than mine and will work well with the Box R Series with a 90mm TB. Otherwise you'll be leaving A LOT of horsepower on the table.
Take a look at my build list - Progress Thread - 12th Owner: My '93 Notchback Restoration & Performance Build | Page 26 | Mustang Forums at StangNet https://share.google/DrGzeA9IRPc08f8C8
My car made 400 rwhp on the current combination and has good drivability. I suspect I will pick up at least 15 more horsepower after I swap from the R Series w/90mm TB to the Box R Series.

Way more clearance with these valve covers. Even the stock throttle bracket clears (with the 1" spacer). I'll have to figure out what color I want to powder coat them and what to do with the breathers. And if I'm going to run this intake or buy something else. Anybody in the market for a very good condition original Cobra intake?

Probably just do black or Ford blue and maybe highlight the lettering somehow. Nothing to crazy.
Probably not. I have a buddy who's trying to talk me into something that flows better as long as I'm this far into it, so peer pressure has me second guessing myself. I do like the old school look of the Cobra. But if I can find the right deal on something better.....
You're supposed to try out and dyno like 12 different ones so that [we] know which one is better. 
Just for info... ThatS an extremely old test, like 3 different retooling of the long r runner intake since...
It's the only one I saw with those two intakes.
Won't find much on revisions from most companies, there advertising and marketing sucks for stuff like that. but that's an old, really old first gen R egr upper with the 2 bolt bosses running threw the throat, the newer non egr ones are a ton better.
Very happy that I chose the Box-R for my combo. Great street manners. Tough to fit under the Heat Extractor hood. It fit nicely, with solid drop mounts, under the 2.5" Kaenen.
Completely redesigned the upper, throat, port taper and floor of it vs that old casting. New ones have the bolt on emblem and only 1 bolt running threw the throat area.
Is that the turbo 363 '93 listed in your profile? What size throttle body?Very happy that I chose the Box-R for my combo. Great street manners. Tough to fit under the Heat Extractor hood. It fit nicely, with solid drop mounts, under the 2.5" Kaenen.
I am pretty sure the new TFS R-Series uppers have either a 75mm opening (EGR) or a 90mm opening (non-EGR). Just wanted to point this out in case anyone was thinking that if they needed to go to a bigger throttle body on the on with the 75mm opening you have to deal with the EGR port right below the opening. I ended up selling my 75mm upper and bought a 90mm upper so I ended up with the new design.
