How Much Horsepower Will GT40 Intake Make Vs. Stock 5.0 Intake ADD BOOST! 

💯

@@Neomustangs Had a question... I know you have a lot of experience for a while now! A couple of months ago I put a 94 cobra upper intake and gt40 lower from a 90's explore on my 94 SN.... It had a small baffle not like my stock intake with a long baffle. And I noticed I was loosing quite a bit of oil! So I added a oil catchcan to it and, sure enough I filled that catch can every time i drove over 60 miles Can you to tell me by switching to the lower with a big baffle will prevent oil suction through PCV??? Somoene suggested I put a 2nd pcv on driver side valvecover up in front of motor. So I did that and it pulls half the amount of oil then before and runs a ton better but still too much oil for my liking. And it dosnt have blow by to myknowledge. Currently have a new 333 stroker with 7000 miles on it now in my 94 GT AODE with stock heads Any help is much appreciated

Yep

Yea I had fun in a few. I Just did a bunch of stuff to a nice 92 LX for a young man. I didn't have the motor open, mainly fixed exhaust leaks, straightened battery/charging system out and tidy up things. It had trick flow alum heads, Holley intake, bbk Cai headers and flowmasters with 3.73s. I don't know what cam or anything but it ran damn good when I was done with it. He got the itch and wants to boost it now lol.

@@Neomustangs True story. I bought an 82, 85, 86 ASC Capri and a 90 Lx. I currently road race an 85 Mustang. Currently building an 88 Turbo Coupe with a Faux Cobra Motor. ( Explorer motor with Roller Rockers and Cobra cam.) Best fun a gear head can have.

Thx man. I do have the deep pockets mods on my other cars who sit and watch me do This lol

Glad you like them!

Nice !

Right on! thank you!

And you as well !

Cousin paul says yes.. that happened.

Appreciate it!!

Welcome to the channel!!

By your pfp it looks very clean, one of the best looking ive seen in a long while

Thanks. Ya it’s a simple. Not perfect combo I enjoy

Glad you like them!

Thx man

Yes sir. Will have to convert next year

Not sure but its 45 with vac off idle. Stock FMU yes.

Thank you!

Any time!

TY

Thanks! Will do!

Keep grinding, youtube is slow demon. it'll come to ya!

@@Neomustangs thanks brother I appreciate ya. 🙏🏻

@@DEMONFOX5.0 YW man!

Ty

Th

Nice. And thanks

One dads car? 275/40/17s

Thanks for the visit

TYVM

Thanks!

Let’s go !

Still working on it? Just curious lol

@@chris_htepo Still working on getting another lol. I ended up getting a Navigator not long after I made this comment. Needed something with 4 doors

@@reptilelovers3850 Nice! I actually always wanted something really spacious like that too but somehow ended up with an 89GT lol funny how that works out.

@@chris_htepo I completely understand how it seems to work that way lol

Good luck!

Yes and yes

Thanks !

Ya i gotta mass air convert for that.

Thanks for the tip

Pretty important to keep an eye on. If you go Race just buy a secondary set of rear wheels and put slicks on it. Be done with it. Same the street drags for street to drive around ok

Thx

Thx

Yes I do! And if theres an issue i alwasy back it up> I have some ECU's i havent sold yet. I usually take them apart to make sure the capacitors arent bleeding or bad before i test them. ANd i repair that when they are.

@@Neomustangs thanks! I'll go check your inventory for it. I'll get with you out there if I don't see them

@@jpp9846 ok

Thx for comment. It’s only 7 pounds

@@Neomustangs how many horsepower per pound of boost?

Always!

Noted! Hmmmmm

Me too I have a Holley systemax intake manifold also on my 89 Mustang it maybe it's just me but when I first put it on it felt fast but now that it's been like maybe 5 years it feels like it got slower Maybe the air velocity is low with this intake

@@michaelgarcia3452 This intake didn't make you slower. The Systemax II is the best intake for the 5.0 Fox up to 6,500. Go to an NMRA Pure Street race and look at what intake most of those guys are running. Its the Systemax.

Maybe I just suck at racing

Fully ported GT40 intake manifold has very competitive flow numbers.

Thanks !

Right.

You dont really need to convert mass air to use heads.

Thats correct. And knowing that, i know that converting to mass air is my only option with GT40 heads. Im arleady doing this intake a disjustice right now ccause it makes more NA and boosted than that. Just limited to 19s.. and no tune ish.

I hate it when people call a explorer intake a "GT 40" ITS NOT A REAL GT40 ITS A EXPLOARE INTAKE. A REAL "GT 40" was tubular

@@bretthusted1167 Here we go.....

@@bretthusted1167 they are very close and also flow the same and also use the same lower. So yes may as well call it a GT40 variant. As far as performance you have a GT40 in the explorer intake for far less money.

Nah just 86 GT

Ty!

Thx i agree! the check valve is in line with the vacuum hose that runs from intake because SD doesnt vent to atmosphere.

@@Neomustangs Thanks man!!! Seems like some people put it on a T fitting and let the boost vent to the atmosphere, but I'm going to take your route and just put it in line.

Dyno

It's worse than that. The PCV valve will pull oil through the cup screen at high rpm and the engine will smoke.

Thx but price wise vs hp gains there really not.

@@Neomustangs are used aluminum heads for good price not available anymore, sorry been out if Foxbody scene for awhile

​@@msk3905 even good used aluminum heads are significantly more than iron gt40 heads.

I paid $1,800 for a set of aluminum gt40 style heads. They have 2.02" intake valves and 1.6" exhaust. I could have gotten away with spending $600 on a set of rebuilt cast gt40 heads but I had a few extra dollars laying around. The front of the car is about 60 pounds lighter with aluminum heads. But best bang for buck would be cast, hands down.

Plan to go 10s on a stock speed density motor and nos first. I already own term X

HAHAH right!

Yes sir.

290 RWHP! ?

The car is plain out of space to make power on 19s. I think 30s and.a tune it makes more power right now

Very rare and people think they’re gold when they try to sell them. I’ve been them listed for $1,500 in some of the foxbody fb groups

Ya that would be cool

Nice !

@@Neomustangs what kind of HP you think iam around? Ball park. What else would you recommend that i could do besides, ( supercharger, turbo, nitrous)? I like it to be street / cruise and dependable, granted stuff happens. We are in our early 50's, and a FOXBODY it's a great way to go MID LIFE CRISIS. LOL. Fun car to drive / cruise. Much appreciated. Darryl

I’m all set thx tho

NOthing it bolted right up? What do you mean? I used the Factory EGR housing that was bored out. I machined it to match.

Curious myself.

Neomustangs me especially so due to current and vehicles 10yrs old or less all for the most part can be either factory retuned using factory software or tuned with aftermarket software without removing the EGR if equipped or any emissions components. Obviously, that’ll only go so far then it’ll be necessary to remove all emissions and go all out for performance. In my case since I need to remain street legal and within EPA & CARB meaning (instant inspection fail if a check engine is on) but, I’d like to get as much power from upgrades like your doing with old blue except the need to keep stock EGR & emissions A.I.R. pump and equipment with at least high flow catalytic converters.

My current application is a 1985 Mercury Grand Marquis LS 2-Door, 302 nothing special 0.030” over bore with stock rockers, pushrods, flat-tappet hydraulic lifters, stock E7 heads & intake with RV cam, EGR & Complete AIR system with TAB & TAD valves, EGR control & EGR Valve solenoids, A/C throttle kicker, Choke control & Exhaust heat control valve all are electronically controlled and vacuum operated and all working, stock 2BBL CFI Fuel injection & TFI Ignition, stock exhaust manifolds with one O2 sensor on passenger side, 8.8 LSD with 3.73:1 gears 28-Spline axles on P225/70R15 tires on 15”X7” 5 on 4.5” rims. In the last year I’ve installed the following new parts, HD spring assisted front shocks, air assist rear shocks, full 2.5” exhaust, magnaflow high flow AIR Assisted Catalytic Converters, H-Pipe, dual flowmaster 40 series mufflers & tail pipes over the rear axle, head gaskets, lapped the valve seats, new valve seals, double row timing set, new front & rear main seals, one piece oil pan gasket, intake & exhaust gaskets, replaced all sensors including EGR Valve, replaced all vacuum lines with new lines, installed a Monster Transmission AOD built for 400HP/450torque with slightly higher 1,600 - 1,800 stall torque converter (factory was 1,300 - 1,500) made a mount and installed three 15” X 7.5” X 3/4” trans coolers 3/8”s ID, made new 3/8”s trans cooler lines added trans temp sensor in the return line, added remote mounted spin-on oil filter for the trans. Removed entire engine harness except harness that goes through the firewall, repaired any shitty Factory Ford wire slices, ran new sensor wires for a tach, coolant temp, oil pressure & trans temp into the factory harness loom, 4-pod A-pillar gauge pod with autometer 2-1/16” gauges, wired PWR & GND for gauges into stock harness loom, wired the gauge lights into the headlight/dimmer harness loom, soldered/shrink tubed all connections and replaced all factory loom tape with Tessa tape & flexible split loom all for stock appearance and fitment, replaced old frayed 10AWG alternator charge wire and fender to block grounds with 8AWG wire, replaced 4AWG PWR & GND’s and added a block to frame 4AWG GND, added a 8AWG GND for the alternator to the regulator on the fender to assure good charging GND’s. Installed new severe duty water pump & Fan Clutch, new 3-Row radiator without factory skimpy trans cooler, new stock 70AMP alternator, new belts, all new hoses for cooling, heating and emissions, fabbed up a functional 2”T X 12”W X 18” hood scoop with fabbed 18” X 4” air cleaner housing to seal under the hood with stock 9.5” X 3” air filter, new distributor, wires, E3.42 spark plugs, new factory 16GAL fuel tank, fuel pump & tank level sender, basic maintenance new fuel filter, air filter oil change & filter, new brakes front & rear, new tires, new 800CCA battery. My problems are, EGR Insufficient Flow fault code and no idea what parts to upgrade to stay reliable, good idle, more power and stay CARB inspected. My idea is a sleeper that has good fun power, ok cruising mileage and passing state inspection. I’m not by far trying to break and power records here, just a fun old paw paw sleeper car, no turbo, NOS or forced induction except for small ram air hood scoop.

Ya did that and failed. It’s speed density. It don’t like to

Yes it will.

Go for the shorter 93 TBird, 94-5 Fox uppers. The intake curve actually reduces turbulence into and out of the TB a little. Appearance is subjective.

Evan Smith did that in a GT stock full interior totally stock engine back in the 90s when he had MMFF magazine. Revnevan on YT.

Yes!

Be honest with you bro, they had a tag on them that was old and fell off. I had those subs for like 10 years. NOS

I know I can make much more with other tuning too but that wasn’t what I wanted to do here

Sounds like your hands are full there !

Honestly I would just use the long block and swap all the foxbody parts over.

@@Neomustangs that would definitely be the best route to go. It’s HARD to find a foxbody 5.0 with accessories that’s not in a car. Guess maybe find a foxbody with a clapped out 5.0 HO, would be the best route.

I’m sorry I’d be lying if i guessed

Thanks and yes

That is correct. 7 pounds at 4500.

Not really.

North East Ohio.

Would a 408 with a super charger be suffice to run with that 373 in the rear

Still have to maf convert.

I did the same and added a 1inch spacer between upper and lower and its 👍

BigDogs ported is much more cost effective.

The whole point was doing a simple Experiment with simple numbers. These are multiplicative with tuning and larger combos

It went away.

Neomustangs good deal, thank you

5000. But you can’t do that on a radial.

We will be revisiting this

@@Neomustangs I'll be looking forward to it. 👍👍

You bet!

Lots of variables. Casting roughness, valve job, bowl ridges, good springs, etc. Minor details. There's 10 HP difference easily.

None

Neomustangs Time for that fuel system and 10lb pulley! Let it eat🤔😝

I don’t think your truck will like 408 on speed density

@@Neomustangs even down here along the gulf coast at sea level? I talked with my tuner and engine builder about it and they weren’t overly concerned with it. I’m *very* new to this so I’m taking all advice I can on this build but was hoping not to have to convert. I’m sacrificing performance I know by stay with the “stock” gt40 intake but I hate to lose that intake with the lightning placard...dang it you may have just spent more money for me 😂. By the way I just found your channel today and I love the style, edits and content. Great job brother!

This works off an fmu.

P over regular but you just have to understand the spark plug dilemma

@@Neomustangs Oh yes. It is going in a Ranger so that is definitely being considered.

Run the maximum lift possible with a particular duration. The earlier the flow maxes out, the longer the flow stays maxed out = more area under the curve = power.
